ABSTRACT. – An annotated checklist of the extant brachyuran crabs of the world is presented for
the first time. Over 10,500 names are treated including 6,793 valid species and subspecies (with
1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families
and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many
resolved. Detailed notes and references are provided where necessary. The constitution of a large
number of families and superfamilies is discussed in detail, with the positions of some taxa
rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the
nomenclature of any large group of decapod crustaceans has been examined in such detail.
KEY WORDS. – Annotated checklist, crabs of the world, Brachyura, systematics, nomenclature.

RAFFLES BULLETIN OF ZOOLOGY 2007
In 1999, Peter Ng visited Leiden to consult Lipke Holthuis
on some problematic Linnaean names, and was shown an
unpublished list of the problems associated with Linnaeus’
and Forskål’s species. This was a project that Lipke
Holthuis, Jacques Forest, the late Isabella Gordon and
Ricardo Zariquey-Alvarez, had embarked on in the 1950s,
but never finished. Lipke gave Peter a copy of these
valuable documents, and also discussed with him what
issues he had been able to resolve, likely answers to
others, and remaining nomenclatural problems. Many of
the most difficult problems are in regard to Forskål’s
names, because almost all his crustacean specimens have
been lost. Wolff (1999: 70) wrote: “The only surviving
crustacean is the type of the amphipod Phronima
sedentaria in alcohol”.
PREAMBLE
There are few things more useful than a catalogue! For
any student of the Brachyura it is a basic starting point to
understanding this group. Not only is a checklist a
resource for checking identifications, but it also reflects
the whole history of the science. For the first and last
authors at least, Serène’s (1968) checklist of the IndoWest Pacific crabs was indispensible. Balss’ (1957)
compilation of genera and families has also been
extremely important in our work. These were our windows
into the literature, and the springboard for discovering just
what the crabs looked like that belonged to all those
names! However, the period from the 1960s through to the
present, has become one of the golden eras of crab
taxonomy — in particular, the decade from 1991 to 2000
saw the description of around 810 new species, the highest
of any period since Linnaeus started classifying them. Not
only new species, but large numbers of new genera, and
significant splitting and rearranging of genera, subfamilies
and families. The crab taxonomic landscape has changed
dramatically in the last 30 years, and it is more difficult
than ever to keep abreast — at least without a new
catalogue that summarises and documents these changes.
It was clear that personal examination of the surviving
Linnaeus, Fabricius, Herbst and MacLeay material would
be necessary. In 1992, through the courtesy of Hans
Gruner, Peter Ng was able to examine the collections of
the Museum für Naturkunde of the Humboldt-University
in Berlin, and in particular, Herbst’s material. A catalogue
of Herbst’s specimens was subsequently published by
Sakai (1999), although not all Sakai’s taxonomic and/or
nomenclatural actions are valid (e.g. see Castro et al.,
2003). In 1999, under Peter Ng’s direction, Tan Swee Hee
(S. H. Tan) visited the Zoological Museum of Uppsala
University in Sweden to examine the remaining Linnaean
specimens. He brought back to Singapore many notes, and
photographs of the still extant types, as well as other
specimens (see also Holm, 1957; Wallin, 1992). In 1999,
together with S. H. Tan, the first author also checked the
Fabricius material in the Zoological Museum of the
University of Copenhagen, matching specimens against
those reported in his papers, as well as against the
catalogue entries of Zimsen (1964). The specimens in the
museum had been stored dried for many years, but were
rehydrated in the 1980s at the instigation of the curator,
Torben Wolff. Wolff (1999: 64) commented: “The
specimens were originally dry and mounted on cardboard.
Since shipment of specimens on loan proved hazardous,
and a slow decomposition was in progress, in the mid
1980s it was decided to transfer the entire collection
(including the 177 types) to alcohol after careful
photographing and rehydration to methods outlined by
Jeppesen (1988)”. Torben was kind enough to give Peter
Ng a set of photographs of the dried Fabricius specimens,
together with Jeppesen’s notes on the material. To
complement this, we rephotographed the rehydrated
specimens, sometimes from multiple angles, and in some
cases, key features were drawn. Some of these have
already been used in a variety of taxonomic papers (e.g.
Ng & Tay, 2001). Finally, on a visit to the Australian
Museum in Sydney, Peter Ng was able to work with Shane
Ahyong to sort and catalogue the surviving material of
Macleay (1838) (see Ng & Ahyong, 2001).
Also, never before has the taxonomic community had a
greater responsibility to make its science available to the
broader community. Without a name, an animal may as
well not exist to humans. Without a name, we have no
framework with which to study the organism, and no way
to understand its unique ecological role. It is only through
a full appreciation of morphological and genetic diversity,
and why this has come about, that we can hope to
succesfully manage, maintain and conserve healthy
ecosystems. Catalogues such as this one, are an important
step in the mapping of the life on our planet.
This idea for a catalogue of crabs has been close to the
hearts of all three authors. Peter Ng began compiling
names from major regional works, revisions, and
taxonomic papers, during the late 1980s. Complementing
and adding to this, was the extensive card catalogue of
brachyuran species built by Danièle Guinot over the
course of her career, and other lists being compiled by
Peter Davie, particularly for the Australian region. The
classification system used was based primarily on the
seminal work of Balss (1957), and the landmark papers by
Guinot (1977a, b, 1978, 1979). As the list grew, it became
apparent that many of the old names posed major
nomenclatural and taxonomic challenges, notably those
from the mid-1700s to the early 1800s. Even the species of
the founding father of modern taxonomy, Linnaeus (1758,
1763, 1764, 1767) were not well understood. Many
Linnaeus species were named from specimens passed to
him by his students and associates, those he had observed
or seen from other collections, or based merely on the
figures of naturalists, notably Rumphius. In the early and
mid-1990s, Peter Ng and his students started to capture the
primary data for the collections of Linnaeus (mainly 1758,
1763, 1764), Forskål (1775), Fabricius (1775, 1793,
1798), Herbst (1782–1804), and MacLeay (1838).
As our simple cataloguing progressed, it became obvious
from our discussions that the brachyuran classification
system also needed a serious overhaul. By the mid-1990s,
many new developments were taking place. With regard to
adult morphology, Danièle Guinot and others were
3
Ng et al.: Systema Brachyurorum Part I
exploring the implications of many new character states,
and extending the use of characters they had proposed the
1970s and 1980s. This was providing substantial new
information on the way crabs should be classified. Larval
morphology was also increasingly being used to provide
insights into phylogenetic relationships. It was also the
beginning of the increased use of molecular and DNA
techniques to elucidate phylogenetic patterns. We realised
that the use of DNA markers, a very powerful tool, would
have major implications for brachyuran classification, but
also that it should not be used in isolation by workers with
little insight into the relationships being increasingly
revealed by the modern use of traditional morphological
techniques. More than ever, a new brachyuran
classification was needed. The key paper of Guinot
(1978) had become a major reference by the mid-1990s,
but many of her ideas needed further development and
refinement, and a number of problems remained to be
resolved. Our simple list thus evolved into the backbone
of a revised classification of the Brachyura — one that we
hope, 50 years on, will be a worthy successor to the
milestone synopsis of Balss (1957). Our work, when all
the parts are finished, is also to go beyond its predecessor,
and will include not only diagnoses of families and genera,
but also species type allocations, and keys to all
suprageneric taxa.
available – it is, after all, the most useful part to help move
forward with alpha taxonomic studies. Also we have had a
number of requests to make our list available to various
public web-based databases intent on providing full
species inventories of the animal kingdom. Some of these
threaten to prepare their own lists if we will not provide
the data – a duplication of effort leading to a waste of
time, money and resources. Another advantage of
publishing the checklist now, is that it should stimulate
our colleagues to pick up mistakes, and to highlight what
we have missed. Such positive criticism is welcomed, and
corrections and additions will be incorporated into the
forthcoming work. Parts 2 and 3 will include the detailed
diagnoses and descriptions of the superfamilies and
families, keys, and a complete bibliography.
Something that we have not included, is distribution
information. We do intend, in the next iteration of the list,
to provide basic biogeographic province data, such as
whether a species is found in the Indo-West Pacific, East
Pacific, West Atlantic, East Atlantic, or Southern Ocean.
This will enable some interesting analyses of relative
levels of biodiversity, and of endemism at both species
and generic levels. Unfortunately we ran out of time to
finish this aspect for the current publication.
We also plan, within the next year or so, to place the list
into our own searchable web-based database, thus making
it freely available to all. This will, we hope, be the basis of
an evergrowing and evolving information system, that will
eventually include full species citations to the primary
literature, as well as regional and country distribution data.
Perhaps, eventually, even links to pdf copies of original
literature, original figures, and photographs will be
possible. The future is soon!
As the list grew in length (and complexity), we were
constantly distracted by emerging nomenclatural and
taxonomic problems. At the same time, we began
preparing synopses of all subfamilies, families and
superfamilies; as well as critically re-examining the
characters that have been used in brachyuran
classification. Along the way, the project assumed a life of
its own, leading Danièle Guinot to dub it our “Grand
Projet”. Through the more than 10 years this project has
so far taken, the data and synopses have been used to help
us with several key publications (Guinot & Bouchard,
1998; Ng, 1998; Ng et al., 2001; Davie, 2002; Guinot &
Tavares, 2003). It has also been used to help colleagues in
their revision of genera and higher level classifications
(e.g. Martin & Davis, 2001; Castro, 2000, 2005, 2007;
Castro et al., 2003, 2004). As we were nearing the final
stage of Part I of our Systema Brachyurorum, Števi
(2005) published his controversial re-appraisal of
brachyuran classification including both fossil and extant
taxa (see Notes later).
While all rational biologists realise that molecular techniques
are powerful tools to be used to better understand
brachyuran phylogeny and classification, there are a good
number of molecular biologists that seem to suggest DNA
datasets are somehow “better” or “stronger” than even the
best morphological data (see Meier et al., 2006, for a
discussion). This is especially so for those who believe
molecular barcoding, using the COI gene, is the panacea for
all species and systematic problems. Molecular datasets
generate interesting hypotheses for morphologists to test,
and morphologists in turn pose questions that benefit
enormously from DNA analyses. Morphologists must take
into account molecular data as additional information to be
assessed; and molecular biologists must not dismiss
morphological hypotheses to dogmatically present
conclusions based on only one or two DNA sequences – for
either group to ignore the other is to do our science a great
disservice. The way to eventual truth must be through an
integrative approach using all available knowledge – this can
come from adult and larval morphology, genetics,
palaeontology, and even ecology, behaviour and physiology.
It was always our intention to publish our Systema
Brachyurorum in its entirety as a single work, with full
justifications of our rearrangements, and of the changes in
status of suprageneric taxa, together with a full
bibliography. However, we have decided to publish this in
three parts for several reasons. Firstly, we are not finished!
Although the fundamental decisions have been made, and
the framework of diagnoses is in place, there are still a
number of character-states to check and compare between
higher taxa. This is time consuming work that would
impede early publication. Secondly, and more importantly,
there is a demand for the checklist now. A number of our
colleagues have already been given parts of the list, and
are exerting growing pressure to have the final product
We end this preamble with a comment made over dinner by
a good friend Maurice Kottelat, one of the brightest
ichthyologists of his generation. In a moment of candour

biology, he sardonically remarked “It seems a parsimonious
lie is much better than a complex truth”. This resonated
strongly with us, and it is our sincere hope that truth will
prevail, no matter how complex.

CAVEATS AND ACKNOWLEDGEMENTS
While we have tried our very best to ensure that the
contents are accurate, the scale of this work means that
mistakes and omissions are inevitable. We encourage
everyone to verify the names in the Systema
Brachyurorum whenever possible, preferably with the
original literature, and to let us know of any mistakes,
errors, and other problems they may encounter. This
compilation represents a first attempt, and we hope to
continue improving and updating it as we can.
The authors would also like to thank Kelvin Lim and J. C.
Mendoza for rendering the wonderful drawings of Dromia
and Calappa, respectively. They have elegantly helped us
capture our sentiments in putting this checklist together.
Martyn Low and Tan Swee Hee have been instrumental in
helping us get this manuscript in a form ready for
publication. For the many photographs used, we thank

arrange for photographs of the many South American
crabs. The copyright for all the drawings and figures
remain with the contributors.
We have been helped by a huge number of colleagues over
the years, too many to name individually, so we hope that
we will be forgiven if we do not name every one. We are
most grateful to Lipke Holthuis, the doyen of carcinology,
zoological nomenclature and crustacean history. Lipke
helped us on many occasions through his hospitality in
Leiden, checking old literature, and discussing complex
nomenclatural problems. He also spent many weeks
meticulously reviewing this work, and offering 30 pages
of suggestions, recommendations and criticisms, which
have very substantially improved the quality of this work.
For him to have undertaken such a huge task with good
spirit and enthusiasm, is a mark of this man’s dedication to
the discipline. He regards this work as a landmark for
carcinological research, and therefore deserving of his
utmost attention. We are grateful and extremely honoured.

Ng et al.: Systema Brachyurorum Part I
Alternative emerging classifications are further discussed
below; and we will take a firmer view with the publication
of Part 2 of the Systema Brachyurorum, when diagnoses
will be given for all higher taxa. Otherwise we have tried
to make a natural system that groups monophyletic taxa as
a reflection of phylogenetic history. This will sometimes
be contentious, and even we have differences of opinion.
For instance, the second author would have preferred to
wait until Part 2 of this project, before using (and
justifing) the recognition of the superfamilies. This is to be
expected from such a large-scale joint project, and in some
cases, what is presented is the best compromise.
Surprisingly, such “compromise” solutions are very few,
and we have agreed on the majority of issues.
INTRODUCTION
Of all the Crustacea, one of the best known and most
intensely studied groups is the true crabs of the infraorder
Brachyura. Brachyuran crabs belong to the Order
Decapoda, the most diverse group of crustaceans alive
today. The measure of their success is reflected in their
colonisation of almost every marine and terrestrial habitat.
They have been found at abyssal ocean depths down to
6,000 metres, and up to 2,000 metres above sea level on
mountains; and are dominant in many estuarine habitats
where salinity and temperatures can fluctuate dramatically
daily. Many species have evolved terrestrial habits,
needing to return to water only occasionally, or just to
release their larvae. Numerous species have become
wholly freshwater, and some of these have even evolved
to survive on transient water sources such as small
phytotelms (temporary bodies of water in tree holes and
between leaf axials), dew, and even water inside empty
snail shells. Some have even been found along the fringes
of deserts. These desert dwellers have been known to
aestivate in clay-plugged burrows for up to six years,
while waiting for rain.
Authorship of Infraorder Brachyura has been attributed to
different authors, notably Latreille. The correct author is
Linnaeus (1758). After diagnosing the genus Cancer,
Linnaeus (1758: 625) headed the first section with “*a*
BRACHYURI Thorace leave lateribus integerrimo”. This
is a valid description, and the infraorder Brachyura can be
regarded as available from this date. The same is true for
the infraorder Macrura, which Linnaeus (1758: 631) wrote
as “*f* MACROURI”.
The basic crab design consists of an expanded carapace
(formed by a fusion of the head and some thoracic
somites), and a strongly reduced abdomen that is tightly
tucked underneath the thorax. In addition, the first
pereiopods of brachyurans are fully chelate, and the
walking legs are placed at the sides of the body. This
evolutionary trend is termed carcinisation, and it has
clearly been very successful. There are now more
brachyuran crab species than any other major clade of
decapods! True brachyuran crabs are often confused with
hermit and porcelain crabs belonging to the infraorder
Anomura. In general, most anomuran crabs have only
three pairs of walking legs clearly visible, with the last
pair being very small and normally positioned under the
abdomen and not visible externally. However appearances
can sometimes be deceptive — some true crabs have their
last pair of legs greatly reduced or even absent; while
some anomurans have become so carcinised, with their
abdomens reduced and tucked under their body, that only
the presence of a telson with uropods makes their true
identity obvious.
The Brachyura can be characterised as follows:
Carapace prominently enlarged relative to reduced abdomen,
usually widened laterally; fused to epistome; carapace with 5
cephalic and 3 thoracic (with maxillipeds) somites; thorax with 5
somites. Front usually prominent, sometimes narrow, triangular.
Carapace usually with well marked lateral linea homolica or
linea brachyura (usually lateral, subventral or dorsal in position)
which may reach most of carapace length or interrupted
posteriorly; occasionally not clearly marked or absent; in
Homolodromiidae, there is a large linea, the whole
branchiostegite is perhaps poorly calcified zone. Eyes stalked,
compound; sometimes reduced; usually in well formed orbits;
eyestalk with 2 articles, first usually reduced. Antennules with
3-articled peduncle; flagella usually short. Antennal peduncles
usually with 1 or 2 free articles; usually without exopod; flagella
usually short but distinct, occasionally very long (e.g.
Corystidae). Mandibles with or without palp; molar and incisor
processes of more or less developed. Maxilla 1 biramous; usually
with bilobed endites. Maxilla 2 usually with endopodal palp.
Maxillipeds with flagella often reduced, sometimes absent;
maxilliped 3 with ischium and merus prominent, usually
flattened, carpus, propodus and dactylus (palp) usually distinct.
Pereiopod 1 always prominently chelate (chelipeds), with fingers
(dactylus and propodal finger) distinctly formed, chela may be
distinctly heterochelous with pronounced cutting or crushing
teeth; fingers may be also heterodontous. Pereiopods 2–5 usually
well formed, usually positioned laterally, coxa fitting into lateral
arthrodial cavities, posterior cavities sometimes subdorsal in
position; pereiopod 4 and/or pereiopod 5 sometimes reduced in
size relative to first 3 pairs, mobile, may be positioned
subdorsally, subchelate to chelate, modified for carrying objects;
pereiopod 5 rarely markedly reduced (e.g. some Cymonomidae,
Retroplumidae, Palicidae), poorly developed (Dynomenidae) or
just restricted to coxa (Hexapodidae). Thoracic sternum either
with paired spermathecae (i.e. internalized structures derived
from sternal modifications of segments 7 and 8, basically a split
between 2 plates of intersegmental phragma, one derived from
sternite 8 and the other from sternite 7; spermathecal apertures
small or large, rounded to elliptical in shape), or with a pair of
vulvae on somite 6. Thoracic sternal plate with sternal sutures
THE HIGHER CLASSIFICATION OF
THE BRACHYURA
The classification used here tries to integrate and
parsimonise what has been published with work we have
done over the years, as well as research we are still
conducting, independently, together, and with our many
colleagues. It is not always easy. What comprise the
“Sections” has been the most contentious area in
Brachyuran phylogenetic research over recent years, and
in particular the monophyly of the Podotremata Guinot,
1977. Strong evidence is emerging that suggests this taxon
is paraphyletic. However, for the purposes of this list,
which is primarily intended as a practical laboratory
document, we continue to recognise the Podotremata.

RAFFLES BULLETIN OF ZOOLOGY 2007
complete or medially interrupted to various degrees and
combinations; sterno-abdominal cavity usually present in males
(in basal podotremes, e.g. Dromiacea, Homolidea, male abdomen
completely filling space between legs or so-named
sterno-abdominal depression; but in Cyclodorippoidea, sternal
plate wide as in Eubrachyura, forming true sterno-abdominal
cavity; for Raninoidea, short abdomen lies in posterior
depression). Two halves of phragma of endophragmal skeleton
joining
interdigitally
(Homolodromiidae,
Homolidae,
Latreilliidae, Poupiniidae) or fused medially (Dromiacea,
Cyclodorippoidea, Eubrachyura); sella turcica present, except in
podotremes. Abdomen generally folded against ventral surface
(rarely first segments remaining visible from dorsal view),
dorsoventrally flattened, often plate-like, sometimes prominently
domed in females, tergites and pleurites not clearly demarcated
(except in some Homolodromiidae), somites articulating
dorsoventrally, no lateral or oblique motion possible; almost
always with 6 somites and telson (or a pleotelson, i.e. sixth
somite fused to telson, in Hymenosomatidae, some
Cyclodorippidae, Majidae and Pinnotheridae), somites may be
fused to varying degrees; in males and juvenile females (rarely
adult females), presence of diverse devices for abdominal
locking mechanism, the most usual being “press-button”. Telson
usually small relative to remainder of abdomen. Uropods in both
sexes always uniramous, never forming tail fan with abdomen's
telson; unreduced (as a small ventral lobe, Homolodromiidae,
some Dromiidae) or plate-like (dorsal in position, Dromiidae,
Dynomenidae and a few Hymenosomatidae); pleopods of somite
6 usually present, in form of small ventral lobes, dorsal plates or
as sockets (for locking of the abdomen), very rarely absent.
Sexes always separate; male gonopore on coxa of pereiopod 5,
coxosternal (but still coxal) or thoracic sternite 8; female
gonopore on coxa of pereiopod 5 or thoracic sternite 8. Presence
of a penis (i.e. external projection of the ejaculatory duct) which
is an intermediate organ to deliver sperm inside G1, varying
from short to very long. Male pleopods 1 and 2 uniramous,
modified into gonopods (G1 and G2, respectively); G1
longitudinally folded incompletely or completely, always
forming tube (cylindrical to very slender and sinuous), structure
for sperm deposition or intromitent organ; G2 whip-like to
rod-like or sigmoidal, inserted into G1 during mating to pump
sperm through; pleopods 3–5 generally absent. Pleopods 2–5 in
females usually biramous, well developed, prominently setose,
oviferous (egg bearing), pleopod 5 occasionally reduced and not
oviferous (Phyllotymolinidae); first pair reduced, uniramous or
absent.
that serve a copulatory or sperm-deposition role acting in
conjunction with the penes; all females either have paired
spermathecae or vulvae on the thoracic sternum. The male
reproductive combination of G1+G2+penis does not exist
elsewhere in the Decapoda. In addition, most male
Brachyura have some form of abdominal locking
mechanism, sometimes remaining efficient in mature
females.
As earlier noted, we have been pragmatic with regards to
the Sections we recognise, and how they are constituted.
Thus, we here continue to use two sections, Podotremata
Guinot, 1977, and Eubrachyura Saint Laurent, 1980 (see
Guinot, 1977a, b, 1978, 1979; Saint Laurent, 1980a); and
within the Eubrachyura, two subsections, the
Heterotremata Guinot, 1977, and Thoracotremata Guinot,
1977 (see Guinot, 1977a, b, 1978, 1979; Saint Laurent,
1980b). We know that this classification is likely to
change, and that there have been some major new
developments over the last 15 years that cannot be ignored
(discussed below), even if perhaps, as a brachyuran
community, we are yet to reach consensus over a
meaningful synthesis.
Most of the contentious issues relate to the concept of the
Podotremata Guinot, 1977. Using spermatozoal ultrastructure, Jamieson (1994) and Jamieson et al. (2005)
supported the idea of a monophyletic Podotremata. In
contrast, a study by Brösing et al. (2002, 2006), using
structural patterns of foregut ossicles, argued against
podotreme monophyly, did not recognise the
Archaeobrachyura, and noted that some of the podotreme
families (e.g. Cyclodorippidae) should be transferred to
the Eubrachyura. In general, many studies on podotreme
monophyly or paraphyly have been severely hampered
because they have used too few representatives (e.g.
Jamieson, 1991, 1994; Jamieson et al. 1995; Guinot et al.,
1994; Schram, 2001; Dixon et. al., 2003; Ahyong &
O’Meally, 2003; Brösing et. al., 2002, 2006).
Guinot & Bouchard (1998) and Guinot & Tavares (2001)
recognised three subsections in the Podotremata: the
Dromiacea,
Homolidea,
and
Archaeobrachyura
(containing the Cyclodorippoidea and Raninoidea).
Recently, Guinot & Quenette (2005) continue to support it
as a monophyletic group, arguing that it is united by a
major synapomorphy that is found in fossil and extant
crabs – females have a strongly modified sternum at the
level of sutures 7/8, and have developed a paired
spermatheca that is intersegmental, internalised, and
independent of the female gonopores on the coxae of the
third pereiopods. Furthermore, using this character, they
recognised two major basal clades, the Dromiacea and
Homolidea, within the Podotremata, based on the fact,
among many others (such as abdominal, gonopodal
features), that they differ in the pattern of the paired
spermatheca. They argue that the “Dromiacea” thus cannot
be used to refer to both the dromiacean and homolid
clades, and should include only the Dromioidea and
Homolodromioidea.
Not all carcinologists, however, have necessarily agreed
that the Brachyura is a monophyletic group. For example,
it has been suggested that some of the primitive crabs,
such as dromioids and their kin, should be referred to the
Anomura (e.g. Spears et al., 1992), but the adult
morphology does not support this contention. Spears et al.
(1992) queried the monophyly of the Brachyuran when
they reported that the DNA of the dromiid, Hypoconcha,
was clearly anomuran; but subsequent studies have
confirmed that this supposition was incorrect (see Ahyong
et al., 2007). Many of the similarities due to shared larval
features between dromiids and anomurans (e.g. Rice,
1980, 1983) are invalid because the considered characters
are all symplesiomorphies (see McLay et al., 2001).
Studies by Jamieson et al. (1995) based on sperm
morphology have also recognised a monophyletic
Brachyura. The true Brachyura is diagnosed by a robust
suite of synapomorphies, with perhaps the most notable
relating to the reproductive system: all male crabs have the
first two pairs of pleopods modified into tubular gonopods
A somewhat contrary view of the Podotremata, however,
7
Ng et al.: Systema Brachyurorum Part I
was put forward by Ahyong et al. (2007). Using the 18S
gene, their analysis of a large number of taxa concluded
that the “… pattern of podotreme paraphyly recovered
herein is not fully compatible with any of the existing
classifications proposed for Brachyura. Non-monophyly of
the ‘primitive crabs’ renders Guinot’s Podotremata
untenable as a formal taxonomic category. Similarly, the
classification of Števi (2005), also with a monophyletic
Podotremata (as Dromiacea), cannot be accepted … For
taxonomic consistency, we propose that the three major
podotreme clades be each recognised as separate sections,
Dromiacea, Raninoida and Cyclodorippoida, alongside
section Eubrachyura.” (Ahyong et al., 2007: 584).
Certainly, the more “crab-like” features of the
Cyclodorippoida have long being noticed (see review in
Ahyong et al., 2007), and the Archaeobrachyura were in
fact placed within the Eubrachyura by Martin & Davis
(2001). If the concept of Ahyong et al. (2007) is to be
accepted, it suggests that the podotrematous condition is
just a symplesiomorphy. Nevertheless it is interesting that
this molecular analysis clearly supported the three
subsections already defined by the foregoing
morphological work of Guinot and others.
Numerous dissections in most groups, notably by Guinot
et al. (in prep.) have demonstrated the sternal condition of
the male gonopores in all the thoracotreme families,
confirming the results previously obtained for Ocypode
cursor (Linnaeus, 1758) (Guinot, 1979: fig. 56-B) and for
Ucides occidentalis (Ortmann, 1897) (von Sternberg &
Cumberlidge, 2001: fig. 3B). One family whose condition
is still difficult to interpret is the Hymenosomatidae (see
discussion under this family). The Pinnotheroidea is also
supposedly thoracotreme, but this grouping itself is
polyphyletic, and because of their small adult size, this
character will need to be very carefully re-examined. The
classification within the Eubrachyura is likely to change
substantially in the years ahead.
At our present state of knowledge, it is perhaps premature
to try to recognise meaningful superfamilies. However
there has been such a strong tendency in recent years to
elevate subfamilies, and recognise new families, that we
felt the practical need for groupings that linked likefamilies, and that at least tried to reflect phylogenetic
relationships.
Some
superfamilies,
notably
the
Goneplacoidea, are groupings based more on convenience
than on knowledge of their affinities. Similarly,
superfamilies like Pseudothelphusoidea and Trichodactyloidea
are a reflection of what we do not know about their
relationships – they almost certainly need to be transferred
to other superfamilies when detailed research is
undertaken. The same is true of some other families. We
had considered placing taxa whose relationships were
uncertain, or doubtful, into a broad category of “incertae
sedis”. However, we felt that this would have been
conterproductive as it would have involved too many
suprageneric taxa.
While the monophyly of the Eubrachyura is generally not
in question, internal relationships are far from settled. The
heterotreme-thoracotreme distinction is produced by two
different patterns of the vas deferens and its ejaculatory
duct, either via the coxa of the fifth pereiopod coxa
(Heterotremata) or through the sternum (Thoracotremata).
The coxo-sternal disposition, which occurs in some
heterotreme families, actually, is only a variant of the
coxal condition since the penis still originates from the
coxa. The coxosternal condition varies considerably: the
penis may be almost completely enclosed by sternites 7
and 8 (e.g. part of Dorippidae, Ethusidae, Palicidae); may
be sometimes covered by accessory plates (e.g.
Chasmocarcinidae); may be exposed but calcified along
most of its length (e.g. Scalopidiidae); or mostly exposed
with episternal plates protecting it (e.g. Vultocinidae). The
heterotrematous condition is the dominant one in the
Eubrachyura, with the most speciose xanthoids,
pilumnoids, and all the true freshwater crabs of this type.
However, evidence suggests that the heterotremes are not
monophyletic (e.g., Brösing et al., 2007, Ahyong et al.,
2007). The thoracotreme crabs are also a challenge – if
this grouping is restricted to the Grapsoidea and
Ocypodoidea, then the available data suggests it may well
be monophyletic. In an interesting study using foregut
ossicles, Brösing et al. (2006) established the
Neobrachyura for some families of the Heterotremata and
Thoractotremata (Grapsidae sensu lato, Ocypodidae sensu
lato,
Gecarcinidae,
Mictyridae,
Retroplumidae,
Potamonautidae, Pinnotheridae, Palicidae) and recognised
the classical grouping of the Oxystomata, including the
Raninidae. This classification, however, goes against
almost every scheme that has been proposed, and
contradicts a substantial body of adult and larval
morphology, as well as DNA evidence. In an upcoming
study, Guinot et al. (in prep.) show that the male sternal
gonopore being unambiguously present on sternite 8, is a
synapomorphy of the Thoracotremata.
In sharp contrast to Števi (2005), we have not used
tribes in this study. From what is published, and from
what we know, many subfamilies are themselves still
poorly defined, so recognising tribes within them does not
seem useful. In particular, it is for the most speciose taxa
that the largest number of tribes have been proposed (e.g.
for the Majoidea and Xanthoidea), but these superfamilies
are precisely those for which the internal relationships are
the least understood. We believe that the elevation and
validation of suprageneric groupings should only arise out
of thorough taxonomic revisionary studies, and then be a
device for better understanding phylogenetic relationships.
FOSSIL FAUNA
The present compilation deals only with the extant fauna
and intentionally excludes the fossil taxa. This is not
because they are less important, but because it is often
very difficult to compare living and fossil taxa without
good fossils, and a holistic understanding of the
Brachyura. This is particularly so when fossils are
fragmentary or poorly preserved, especially when the
sternum, abdomen and gonopods are absent or poorly
preserved. While the condition of fossil material is a major
constraint on paleontologists, a heavy reliance on the
available preserved parts to help determine actual
8
RAFFLES BULLETIN OF ZOOLOGY 2007
phylogenies is questionable. Schweitzer (2003) argued for
the use of what she called ‘proxy characters’ (mainly
external carapace features) because they help track the
more fundamental anatomical features of the crabs which
are not preserved (see Schweitzer & Feldmann, 2000a;
Karasawa & Schweitzer, 2006). However, the study of
extant crabs has demonstrated on many occasions the
inherent danger of relying on proxy characters, with
convergence rampant in many taxa (see discussions in
Xanthoidea, Pilumnoidea, Trapezoidea, Grapsoidea etc.).
The extensive studies of “ventral” characters by Guinot
(1977a, b, 1978, 1979) “… has initiated a dramatic
revision of our picture of crab systematics and evolution”
(Bishop, 1993). For palaeontologists, these characters are
only available when the fossils are more intact and/or
when it is possible to separate the fossil from the matrix it
is embedded in.
We here recognise 6,793 named species and subspecies.
For these species, we also recognise 1,907 synonyms.
These species are in 1,271 valid genera and subgenera
(with 393 synonyms), 93 families and 38 superfamilies.
By no means have carcinologists reached a “plateau” in
the discovery of new species. There are still many new
species of freshwater crabs in the Potamoidea,
Gecarcinucoidea and Pseudothelphusoidea that await
description in the work bins of colleagues, and even
more that have yet to be even discovered. Yeo & Ng
(1998) estimated that one-third of the Indochinese fauna
still awaits discovery, a similar ratio to that estimated by
Cumberlidge & von Sternberg (2002) for the
Madagascan fauna. In a recent global analysis, Yeo et al.
(2008) estimates that the number of new freshwater crab
species awaiting discovery ranges between 128 and 846.
Most of the world’s tropical mangrove systems are still
not well explored, and many grapsoids and ocypodoids
still await formal naming or discovery. The marine
habitats are also still poorly surveyed, with the deep sea
proving to be a far richer habitat than previously believed.
New habitats continue to be discovered, with rubble beds,
deep reefs and hydrothermal vents proving to be very
diverse. New methods such as the now widespread use of
colour photography of fresh specimens, and an expanding
range of new morphological characters being used, are
helping to resolve many species-complexes. These,
coupled with the use of increasingly powerful molecular
tools, have enabled us to identify many cryptic and sibling
species in recent years (e.g. Ng et al., 2002; Lai et al.,
2006), even for commercial species like Portunus
pelagicus (see Lai et al., in prep.) and Scylla serrata (see
Keenan et al., 1998)!
Ng (1999b: 237) commented that “Paleontologists
working on recent brachyuran fossils and carcinologists
studying the extant fauna do not always work hand in
hand. As a result, one often wonders how many of the new
species described on the basis of recent fossils are in fact
conspecific with new species described from fresh
specimens. Carcinologists studying living species on the
other hand, rarely consult palaeontological papers.
Comparisons in any case between crab fossils, which are
often represented only by broken and incomplete pieces,
and fresh specimens with their full suite of characters, are
often impossible.” However, many older and most modern
papers have provided precious information which has been
key in a better understanding the phylogeny of the
Brachyura. When fossils are well preserved, and/or the
study is accompanied by a solid understanding of extant
taxa, significant progress has been made (e.g. Guinot &
Tavares, 2001; Guinot & Breton, 2006). A major work,
such as the Treatise of Glaessner (1969), has been and still
is a very important tool in helping carcinologists
reconstruct crustacean phylogeny. Clearly, a greater
synergy needs to be established between students of the
living fauna with palaeontologists so that some of the
problems can be overcome (e.g. Schweitzer et al., 2003).
With regards to fossil taxa, almost 1,600 species are known
at present (R. Feldmann, C. Schweitzer, pers. comm.).
DESCRIPTIVE TERMS
Carapace. The carapace is a cover, a shield of variable
extension, and sometimes lateral expansion. It probably
does not correspond to the tergum. It is effectively one
continuous plate, but the surface may be covered by
grooves of various depths demarcating associated regions.
We follow Guinot (1979) in using the term to mean only
the dorsal plate. Some authors use the term “cephalothorax” in place of carapace (e.g. Števi, 2005), but this
term actually refers to the entire structure of the fused
cephalic and thoracic somites, and not just the dorsal
shield. The regions usually correspond to the positions of
various internal organs and structures, and thus they have
corresponding names. The gastric region (including the
epi-, meso-, meta- and urogastric regions) corresponds to
the oesophagus and part of the foregut; the cardiac region,
the cardiac portion of the stomach; intestinal region, the
intestines; branchial region, the gill chamber; and so on.
Some major grooves have names, though most do not. The
so-called cervical grooves separate the branchial and
gastric regions; the inter-epigastric groove separates the
two epigastric regions; and the gastro-cardiac groove
(often called the H-shaped groove) is deep and prominent
HOW MANY CRAB SPECIES ARE THERE?
Until now, most workers have quoted the key paper of
Chace (1951) which cited 4,428 species distributed in 635
genera. These numbers had been based on the extensive
card catalogues, meticulously maintained throughout the
century, in the Smithsonian Institution. It appears Chace
was very close, as according to our present list, by 1950
there had been 4,120 species described. This small
difference could perhaps be largely accounted for by
species now in synonymy. Since then, no one has
attempted to provide an accurate update. Published
estimates range from 5,000 to 10,000 (Ng, 1998; Martin &
Davis, 2001; von Sternberg & Cumberlidge, 2001; Yeo et
al., 2008). Boschi (2000) and Hendrickx (1995a, 1999)
prepared major species lists for the Americas, but because
the center of brachyuran diversity is in the Indo-West
Pacific, a great many species were not covered.

Ng et al.: Systema Brachyurorum Part I
in many crabs. In most crabs, there is a pair of prominent
transverse submedian pits (gastric pits) between the metaand urogastric regions, corresponding to the endophragma
on which the stomach muscles are attached.
meet, a tooth or lobe is usually present, this is the external
orbital tooth (also called exo-orbital or exorbital tooth or
angle). The inner edge of the infraorbital margin usually
stops well before the base of the eye or antennules, leaving
a distinct orbital hiatus (gap). As such, the supra- and
infraorbital margins demarcate an ovate, often deep
depression in which the eyestalk lies, and is at least
partially protected when it is retracted. These are what is
defined as complete orbits. In some crabs, the supra- and
infraorbital margins do not fuse or meet along their outer
edges (e.g. some Gecarcinidae), these can be regarded as
incomplete orbits although most of the eye is still
protected. Orbits can be quite shallow in some crabs (e.g.
Lambrachaeus ramifer), and one group, the
Hymenosomatidae, do not have orbits and the short eyes
are completely exposed. The form of the orbit in the
Majidae is highly variable, and often poorly defined and
incomplete. In some majids, the various supraorbital,
subhepatic and suborbital spines and lobes effectively
form a protective hood around the eyes, but this is
different from the true orbit of other crabs. Homolids are
also unusual; while the eyes superficially appear to be
sitting in an orbit, there is actually no clear structure
serving to protect the retracted.
There are various systems for recognising carapace
regions, and these have been developed for the taxonomy
of particular groups. For example, Dana (1852a: 74)
developed a system, still used today, to denote each of the
many complex regions and subregions on the carapace of
xanthids. As far as possible we have tried to use a
commonly understood generic terminology.
The shape of the carapace is typically described, and
commonly used in keys. In many cases however,
especially in large diverse groups, carapace shape can vary
dramatically, and in these cases it is not useful in helping
to define the group. However, sometimes the shapes can
be distinctive and therefore we continue to use it.
Unfortunately, until recently most of the descriptive terms
used to describe shape have not been standardised. We
here follow Ng (1998) in defining the various carapace
shapes encountered, even though some of the categories
can be subjective.
The suborbital, subhepatic, pterygostomial and
sub-branchial regions are usually clearly defined, often
separated by distinct grooves or rows of granules. In some,
the subhepatic regions may be deeply excavated.
It is not certain if the orbital structures in all families are
truly homologous. For example, the elongated orbits of the
Ocypodidae may actually be ontogenetically formed from
the original short true orbit combined with a lateral
transverse depression of the carapace.
Front. The front is the anterior region of the carapace
lying between the inner orbital angles; it is marked
anteriorly by a frontal margin, which in most crabs, is
obvious and prominent. The frontal margin may be
deflexed or straight, and variously shaped, from multi- to
bilobed or dentate, lamelliform, sharp and narrow to very
broad and occupying most of the carapace width. It is
most often clearly demarcated from the orbits. The
so-called "rostrum" in "horned" crabs like some homolids
and many majids is an anterior extension of the frontal
margin. We do not formally use the term "rostrum" as it
may suggest an affinity to the rostrum of Macrura and
prawns, and we remain unsure if they are homologous
structures. In some homolids, the front (or part of it) is
formed by elongated accessory and postfrontal spines, and
for these crabs the term "pseudorostrum" has been coined,
and we here use that term as required. In some crabs, the
ventral margin of the front may have a longitudinal ridge
or carina which can be lamelliform distally (some
Hymenosomatidae). In some freshwater Parathelphusidae,
the frontal margin takes the shape of a median triangle
formed by the median part of the cristate front being
sharply bent downwards, and with a new transverse
cristate margin forming across the top; in some species
particularly, this triangle may be very prominent.
Carapace margins. The anterolateral margins of some
crabs are not well marked (e.g. Homolodromiidae) but
generally are distinctly defined, and convex (sometimes
referred to as arcuate); and may be entire, dentate, spinate,
rounded and/or cristiform. If teeth and lobes are clearly
defined, they are almost always counted from anterior to
posterior. The external orbital tooth is often counted as the
first anterolateral tooth (as we do here), but many also
treat it as a separate orbital tooth. The last anterolateral
tooth is usually, but not always, the most prominent, and
the one that demarcates the beginning of the posterolateral
margin. In some groups such as the Potamidae,
Parathelphusidae, Grapsidae and Gecarcinidae which
typically have only one or two teeth close behind the
external orbital tooth, the term epibranchial tooth or teeth
is often used instead of anterolateral tooth. This is because
they are placed at the edge of the epibranchial region
which is the anterior part of the branchial region. Some
authors also refer to the last anterolateral tooth in
Portunids as an epibranchial tooth, but this is not accurate
as it is placed too far posteriorly.
The posterolateral margins in most crabs converge toward
the posterior carapace margin, and varies from from
convex, straight to concave. In some (notably some
euxanthines and actaeines, Xanthidae), the posterolateral
margin is deeply concave to receive the ambulatory legs.
Orbits. In most crabs the orbits are well defined, formed
by a prominent supraorbital margin (which may be
cristate) which curves inwards to meet the front
(sometimes smoothly or by an inner supraorbital lobe or
tooth), and curves outwards to meet the infraorbital
margin beneath. Where the supra- and infraorbital margins
In a few groups of crabs the antero- and posterolateral
margins cannot be easily distinguished, with one gradually
curving to another. In the Corystidae the lateral margins
10
RAFFLES BULLETIN OF ZOOLOGY 2007
form a single evenly convex margin, and may even bear
teeth posteriorly. In others, particularly the Grapsidae and
Ocypodidae, the margins are straight with no anteriorposterior separation, and therefore they are simply referred
to as the lateral margins.
The antenna (or “first antenna”) is uniramous, and usually
has numerous articles; with the first and second articles
often confusingly named. The first antennal article, lodged
in the epistome, contains the osmoregulatory Green Gland,
which has a urinary function and an external opening
(“article urinaire” in French). This article is often small
and less strongly calcified compared to others. The most
prominent article basally is actually the fused second and
third articles (hence its size); and most workers refer to
this (somewhat erroneously but conveniently) as the "basal
article" or “basal segment”. We follow convention in
using basal article for this structure. The basal article, is
usually the largest antennal "article", can be lodged in the
orbital hiatus, and may be fused with the epistome to
varying degrees. Following the basal article is usually a
series of smaller and/or more slender articles which
develop into, an often long, sensory flagellum.
Proepistome and epistome. The proepistome (also
known as the inter-antennular septum) is the sternite of the
cephalic somite which bears the antennules. The epistome
itself is the sternite of the cephalic somite which bears the
antennae. The epistome in most crabs is clearly marked,
although in some, it may be depressed and sunken. The
epistome is often divided into two parts, with the posterior
part larger. The anterior part is usually narrow, but in
some (Homolodromiidae, Homolidae), it is relatively
prominent. The posterior margin of the epistome is often
crenulated and the lateral margins may be semicircular.
Usually there is a median protuberance (tooth or lobe) but
it is sometimes entire.
The older nomenclature for the antennae and antennules
can get confusing. The antenna is often called the "first
antenna" and the antennules the "second antenna" because
earlier workers have counted in from the eye, and perhaps
because the “first antenna” is typically more prominent,
with its long flagellum, than the second which is tucked
into a fossa under the front. However, as noted earlier, the
antennule is actually from the proepistome while the
antenna is from the epistome, i.e. the antennule is derived
from a somite anterior to the antenna. Thus, from a
development point of view, the numbering is incorrect and
not in the order of the somites they are derived from.
Buccal cavern. The buccal cavern (where the mouthparts
are located), is bordered by the pterygostomial regions
laterally, and the epistome above, and is usually
demarcated by cristate to semicristate margins. The
calcareous plate at the inside bottom of the buccal cavern
(at the base of the mouthparts), is known as the
endostome. Usually, only the anterior part of the
endostome is visible, even if the mouthparts are moved
aside. The endostome sometimes has obliquely
longitudinal endostomial ridges which vary in strength and
extent (may reach anterior and/or posterior parts, and thus
are said to be complete or incomplete). These ridges direct
the efferent branchial water current.
Mandibles, maxillae and maxillipeds. The mandibles are
crushing or cutting structures and are always calcified,
even in symbiotic species. Carnivorous species tend to
have sharp cutting edges while herbivorous ones have
more molariform structures. In parasitic species, the
mandibles are rather weak. The mandibular palp usually is
well developed and in life, normally covers the outer
surface. It has either two or three articles, with the distal
one usually large. In many crabs, the base of the distal
article has a dense row of setae; and in a few freshwater
families
(Parathelphusidae,
Gecarcinucidae
and
Pseudothelphusidae), the base of the distal article has a
strongly produced accessory structure which is as long as,
or slightly shorter, than the actual article, thus forming a
bilobed structure. The morphological or adaptive
significance of this structure is not known.
Eyes. The eye has two articles, the basal (basophthalmite)
and ocular (podophthalmite), with the latter usually the
longer and more prominent. The tip of the eye usually has
a pigmented and rounded cornea. However the eye can be
substantially
reduced
in
many
cavernicolous,
hydrothermal (e.g. in the Bythograeidae, as Austinograea,
see Guinot, 1990) and deep water species, and even some
living in silty mud. In these cases it is fixed in the orbit,
and although the eyestalk is reduced and the cornea almost
lost, it is always discernible. In smaller individuals of the
hymenosomatid Cancrocaeca xenomorpha where the eye
seems completely absent (Ng, 1989), larger individuals do
have discernible structures which represent the remnants
of the eyes (see Naruse et al., in press).
The first and second maxillae are smaller than the
maxillipeds, flattened and biramous, and are rarely used in
taxonomy. They have, however, proved useful in some
groups such as the Cryptochiridae, Trapeziidae,
Pilumnidae and Ocypodidae. In filter and detrital feeding
crabs, the maxillae (as well as the first and second
maxillipeds) have numerous long setae to help sift and
sieve the sand/mud particles for organic matter.
Antennules and Antennae. The chemosensory antennules
(sometimes called “second antennae”) are usually lodged
in fossae, with the basal article often large, and the rest of
the articles forming a flagellum which folds against the
basal article. The flagellae are always short, and are rarely
much longer than the maximum length or width of the
basal article. The distal segments are invariably shortened,
and are distally biramous and appear hook-like. The distal
segments usually fold transversely, obliquely or
sometimes vertically into the fossae, although in some
cases, they are only partially folded, and in some
gonoplacoids (e.g. the Chasmocarcinidae) the fossae are
lost, and the flagella are always exposed.
Of the three pairs of maxillipeds, the third maxillipeds are
the anteriormost structures most frequently (and easily)
used for taxonomy. In some crabs like dotillids
(Ocypodioidea) and mictyrids, the third maxillipeds are
large and almost foliose, covering most of the buccal
11
Ng et al.: Systema Brachyurorum Part I
cavern to form a chamber. This perhaps assists the other
mouthparts in sieving the sand and mud for food. This is
also the case for filter feeders like Baruna
(Camptandriidae). In suspension and detrital feeding
crabs, the first and second maxillipeds have numerous
very long setae on the inner margins. Detritivores use
these setae for sieving sand and mud. Suspension feeders
on the other hand, extend these setae beyond the open
third maxillipeds when feeding, actively filtering the water
for plankton. In the varunid genus Gaetice, the third
maxillipeds themselves have elongated palps bearing long
setae that are similarly used for suspension feeding.
always a well developed cheliped (or pincer), and is here
referred to as such rather than P1. The cheliped consists of
a freely articulating coxa, a basis and ischium which are
usually fused, an elongate merus, typically short and
rounded carpus, and a propodus which is developed into a
prominent manus (or palm) and pollex (or fixed finger).
The last article, the dactylus, is recurved and articulates
with the pollex to form a strong pincer. The manus, pollex
and dactylus are together usually referred to as the chela.
The cutting edges of the two fingers are usually dentiform
to varying degrees, and in some species, the bases have
large molariform teeth for crushing, or strongly recurved
teeth for cutting. Sometimes the major cheliped may act as
a “crusher”, while the minor cheliped is the “cutter”.
Occasionally, the fingers may even be cultriform
(blade-like). The tips of the fingers are usually sharp, but
many groups have evolved spoon-tipped fingers to varying
degrees for scraping. In some, the distal parts of the
fingers are scalloped, with one side convex or flat and the
other side excavated.
The forms of the merus and ischium of the third
maxillipeds are perhaps the most often used characters in
taxonomy. The merus can have the anteroexternal angle
strongly expanded to form a prominent auriculiform
structure, or it may be quadrate, or even effaced. The
merus and ischium are usually free, but in a few (e.g.
Camptandrium
[Camptandriidae]
and
some
Pinnotheridae), they may be fused and the suture
completely absent. The ischium usually has a median or
submedian sulcus (depression). In some Brachyura, the
inner lateral margin of the ischium has a straight and entire
low crest, and may have in addition, a submarginal low
crest (inner surface) which is weakly or strongly serrated.
Whether this serrated submargin (and perhaps the entire
marginal crest) is homologous to the so-called “crista
dentata” (which consists of a double row of serrated
crests) of the Reptantia of Richters & Scholtz (1995)
remains to be seen. The ischium is usually not fused with
the basis, and the suture between them is clearly
discernible (though sometimes medially interrupted). Even
so, in most cases the two articles are not really mobile. An
exopod is usually present in most crabs, but is often
reduced and rarely absent in some freshwater and
terrestrial crabs (e.g. Pseudothelphusidae and fully
terrestrial crabs). When present, the exopod usually bears
a long flagellum which tends to be reduced or even lost in
some freshwater crabs. The first maxilliped is occasionally
used taxonomically, especially whether the endite is
distinctly notched and a lobe is present, the so-called
“portunid lobe” (e.g. most Portunidae).
The form and function of crab chelae has received a
good deal of study. Invariably, they are associated with
feeding, but also for defence, and in some groups for
social behaviour such as intraspecific aggression or
courtship. Prominent molariform and cutting teeth are
associated with feeding on molluscs. It has also been
shown that crabs which use a special cutting (or
sometimes called “peeling”) tooth almost always have
this structure on the right cheliped as an adaptation to
deal with more commnonly found right-apertured
gastropods! Such crabs (e.g. Calappidae, see Ng & L.
W. H. Tan, 1984a) also have the fingers of the left chela
elongate and forceps-like to aid in extracting the
“peeled” gastropod. Invariably, powerful crushing and
cutting teeth are associated with a massive, often
swollen manus. Not much is known about the function
of spoon-tipped fingers, but they seem to be generally
used for feeding on detritus, scooping up mucus from
corals, scraping off encrusting algae, more effective
gripping of filamentous algae, scraping of coral rock, or
picking up very soft foods. Scalloped fingers are
primarily for scraping, be it encrusting algae off rocks
and bark, or thin layers of leaf epithelia; although they
also make quite effective cutters.
Appendages and pereiopods. Standardising names for
the various appendages is not easy. We here refer to limb
and pereiopod segments as articles, to differentiate them
from the body segments, referred to as somites (except in
the case of some fused abdominal somites, see below
under Abdomen). It is important to do so, as the
“segments” of appendages have a different derivation
from those of the thorax and abdomen. The eyes,
antennules, antennae, the calcified jaw-like mandibles
(with a mandibular palp), and the first and second maxillae
(sometimes termed maxillules) are all cephalic
appendages. Although the eye, antennules and antennae
are anterior and sensory in function, the mandibles and
maxillae are always associated with the mouthparts.
In some crabs, the base of the fingers and/or base of the
chela has part of the cuticle weakly calcified, forming
“windows” or “tympana” (e.g. Benthochascon, Portunidae). The function of these structures is not known but
may be associated with pressure detection or sexual
selection. Similarly, some homolids have darkened and
somewhat decalcified patches on their chela that are
believed to be photophores (Williams, 1976a).
The next four pairs of pereiopods are mostly used for
walking and are often referred to as walking or ambulatory
legs. However, many crabs have some or all of these legs
modified for other functions like swimming, burrowing,
grasping objects etc., and one or more pairs, principally
the last pair, may even be vestigial (the Hexapodidae have
a vestigial coxa). We refer to them as P2 to P5, with P2
The next five pairs of appendages, all thoracic, are for
locomotion or manipulation, and are usually referred to as
pereiopods (abbreviated as P1–P5). The first pereiopod is

being the first walking or ambulatory leg.
cannot move. This helps the crab grip very tightly onto the
substrate. Only when the muscles are relaxed can the
dactylus be released. Many such crabs also have strong
hook-like dactylus. In some coral crabs (e.g. Trapeziidae),
the tip of the dactylus has rows of setae and/or transverse
ridges which help scrape off coral mucus for food. Some
semiterrestrial crabs (Dotillidae, Ocypodoidea) have an
unusual "window" on the meri of some or most of P2–P5.
This decalcified patch is often incorrectly called a
tympanum but is now believed to aid respiration by
absorbing atmospheric oxygen to prolong time away from
water.
Many podotremes have the last one or two pairs of legs
modified for carrying objects. In these cases, the dactylus
and propodus form a subchelate to chelate structure, often
with associated spines, setae and teeth, to aid in carrying
objects. In some latreilliids, the dactylus is neither chelate
or subchelate but hinges enough to appress tightly on the
margin of the propodus so as to still hold objects. This is
believed to be also the case for poupiniids, because the leg
is also positioned subdorsally and extremely mobile,
suggesting the P5 may have a carrying role (see Guinot et
al., 1995). Among the podotremes, only the dynomenids
(which have P5 strongly reduced and obliquely
positioned) and raninids (which use the legs for
burrowing) definitely do not carry objects. Among
eubrachyurans, the carrying behaviour is much rarer. In
fact, only the dorripids and ethusids practice this, with
their P4 and P5 modified like those of the podotremes.
Some majids (e.g. Oncinopus and Achaeus, Inachidae)
have their P4 and/or P5 modified very much like those of
carrying crabs, with the dactylus and propodus subchelate
to chelate. From what is known, they do not use these
structures for carrying, but instead, for clinging tightly on
to branch-like substrates in areas with strong currents;
with their carapaces, chelipeds and other legs dangling in
the current to gather food.
Thoracic sternites. The thoracic sternites have a number
of important taxonomic characters, and are increasingly
being used. These usually relate to the shape, and the
pattern and degree of fusion between the somites.
Although the cephalon and abdomen also have sternites,
these are so reduced or modified that they are not
taxonomically useful. For convenience, we will just refer
to the thoracic sternites as sternites. The presence/absence
and/or extent of the sutures between somites is important.
The suture between sternites 7 and 8 is abbreviated as
S7/8, and this pattern is similarly used to refer to other
sutures. Sutures between sternites are not always complete
and are often medially interrupted. In basal podotremes
(Homolodromiidae, Dromiidae, Dynomenidae), only the
lateral parts of the sutures are visible.
There are various modifications of the pereiopods for
swimming. The Portunidae have the dactylus and/or
propodus of P5 distinctly dorsoventrally flattened and
paddle-like, while in Matutidae, P2–P5 are all thus
modified. In some dorippids and cyclodorippids, the
dactyli and propodi, while flattened, are still relatively
narrow, but have rows of long dense setae on each margin
to increase the surface area. Paddle-like legs are not only
associated with swimming, but can also be effective for
digging; large Scylla (Portunidae) are unable to swim but
use the same paddle-like last legs for digging into mud.
Burying and burrowing crabs often have the same features
as swimmers, but in many (e.g. Raninidae), their dactyli
and/or propodi are generally less bilaterally symmetrical
and are spatuliform to subspatuliform in structure. Also,
some crabs (Matutidae, Orithyiidae) are both swimmers
and burrowers, so their legs have features intermediate
between the two. In many luteophilous crabs
(mud-dwellers), the dactylus of P5 is relatively slender but
distinctly upcurved; the spatuliform structure helping them
burrow into soft sediments.
Many podotremes also have sternocoxal depressions on
the outer edges of the sternum into which the inner edges
of the coxae of the pereiopods fit. They are deep in the
Dromiidae, Dynomenidae and Homolodromiidae, shallow
in the Poupiniidae and Homolidae, and absent in the
others. Almost all members of these families use the coxa
of their legs in one manner or another to hold or "lock"
their abdomen to the sternum; and it seems likely that this
depression helps guide the pereiopodal coxae into
position. For the coxa to function as an abdominal lock as
well as aid in locomotion clearly necessitates slow and
precise movements of the periopods. Homolids and
poupiniids, which also use an homolid press-button and
the base of the third maxillipeds to help lock the abdomen,
have correspondingly shallow sternocoxal depressions. By
relying less on the pereiopodal coxae for this purpose, they
allow the pereiopods more flexibility. Latreilliids are
interesting as they do not use their pereiopodal coxae at all
to hold their abdomens. Other podotremes, with a wider
thoracic sternum, and which have special abdominal
locking mechanisms (e.g. Cyclodorippidae), do not use
their pereiopodal coxae at all for this purpose, and are
generally more agile crabs.
Crabs which live in rocky areas or reefs usually have P5
smaller than the rest, and the leg positioned slightly
subdorsally; this helps them anchor themsleves in cavities,
especially when resisting predators. Many slower crabs
which live on such substrates and those which are obligate
associates with corals have a special dactylo-propodal
articulation on P2–P5, formed by a rounded prolongation
of the lateral margin of the propodus which slides against
and beneath a projecting button situated proximally on the
lateral margin of the dactylus. When the dactylus is
positioned at about 90° to the propodus and the muscles
contracted, the two articles are effectively locked and
In a few crabs, notably species of Trichopeltarion and
Podocatactes (provisionally in the Atelecyclidae), the
sternum becomes markedly asymmetrical. We believe this
is due to the possession of an exceptionally large cheliped
in these species, requiring a large muscle block, in an
expanded sternal compartment, to support and move it.
The wider part of the sternum is always at the base of the
enlarged cheliped. We have observed this phenomenon
only in crabs with a narrow sternum. Presumably, crabs
13
Ng et al.: Systema Brachyurorum Part I
with a broad sternum have sufficient space inside the
sternites for the enlarged muscles. Certainly, such
asymmetry is not known in Uca.
segments, but this can be misleading. Segments may have
their sutures still distinct externally but may be ankylosed
to varying degrees underneath, rendering the segments
effectively immobile (e.g. Geryonidae). We here regard
fusion as segments which are immobile and cannot
articulate with each other, regardless of whether the
sutures are visible. It is also important to note that the
depth of the sutures may be affected by age and growth,
and in very young crabs, the sutures may be deep and the
fusion between segments may not have occurred.
Endophragmal skeleton. The internal endophragmal
skeleton of crabs is an important character and will be
valuable in future systematic studies. What is known now,
from the study of selected examples, suggests some broad
patterns. How the endosternites from each half of the
skeleton join medially is important. For most modern
crabs, the endopleurites coming down from the pleural
roof are fused to the endosternites, forming a more or less
single structure. In some families (Homolodromiidae,
Homolidae, Latreilliidae and Poupiniidae), the two halves
of endosternites join interdigitally (or interlaced). Also
very important is whether a sella turcica is present. This
term is used to denote a special part of the endosternal
phragma which links the tagma/thorax to the
tagma/abdomen (intertagmal phragma) and is fused, in the
Eubrachyura, to both endopleural and endosternal
phragmae. Such a sella turcica, which plays the role of
transversely joining between the two separate half
endophragmal structures, is not present in the podotreme
crabs, nor in other Decapoda, and is closely associated
with how the thorax and abdomen are connected. Modern
crabs have a well defined sella turcica, but not
podotrematous ones.
Although the number of segments in male and female
abdomens is the same, there can be sexual dimorphism in
regard to segmental fusion. Male xanthids, carpiliids and
parthenopids for example, have segments 3–5 fused but
their females have all segments free. Male leucosiids
usually have segments 3–5 fused but in some females (e.g.
Leucosia), most of the abdominal segments are completely
fused and form an immobile cover. Male latreilliids have
all segments free but females have some of them fused.
These female crabs have the abdomen highly domed and
modified into a brood pouch to varying degrees, with the
eggs completely protected when the abdomen is closed. In
such cases, at least two (usually more) of the segments are
fused. For nomenclatural convenience, the segments are
here abbreviated as A1 to A7.
The role and significance of fusion has yet to be
determined, but presumably, it helps hold the abdomen
against the sternum more easily, or makes flexing easier,
especially during mating. A large number of crabs have
A3–5 fused, but whether this is phylogenetically
significant or mere convergence is not known. Certainly in
many groups, this is a very diagnostic feature. In some
groups like Cyclodorippidae, Majidae and Hymenosomatidae, there is a great diversity of combinations!
Abdomen. Most crabs have six abdominal somites (or
pleomeres) and a telson. The telson is frequently referred
to as “segment 7” or even “somite 7” by many workers,
but as it never has any associated appendages, it is now
not regarded as a true metamere. For nomenclatural
convenience, however, we find it convenient to refer to all
the somites as well as the telson as “segments” in a broad
non-specific sense. Segment 7 (or telson) is present in all
crabs and is usually free, but in a few groups (e.g. in the
Cyclodorippidae,
Hymenosomatidae,
Pinnotheridae,
Majidae), it may be fused with segment 6, and is then
referred to as the pleotelson. Almost all crabs have 7
segments (although some may be fused, see later), but in
the Hymenosomatidae, there are only 6 segments and it is
likely that this is associated with the absence of a
megalopal stage (another unique feature of the family). In
crabs, the number of abdominal segments increase through
ontogenesis, and the loss of the megalopa is probably
associated with hymenosomatids lacking a segment. Also,
in many species of Cyclodorippidae and some
Hymenosomatidae and Majidae, it is almost impossible to
discern the individual segments, and it is only an
assumption that they have the normal number of segments
for the family. For most crabs with 7 abdominal segments,
segments 1–6 are usually free but in many groups, it may
be fused to varying degrees. Some authors count fused
segments as one, but this is inaccurate and often
confusing. In most cases, even when segments are
completely fused and the sutures between them absent,
traces of individual segments can still be discerned.
Nevertheless, for the present purposes, we count all
segments and indicate which are fused. There is also often
confusion as to what constitutes fusion. Many authors just
look for the presence or absence of sutures between the
The anus, which is normally on segment 6 (A6) in
Decapoda, extends more posteriorly into A7 (telson) in
Brachyura. This means that most crabs can defecate by
just slightly flexing segment 7 and with the rest of the
abdomen closed and locked either by the legs (basal
podotremes) or by a press button (Eubrachyura).
The abdomen of males and juvenile females (i.e. females
before the puberty moult) of most crabs are able to "lock"
onto the sternum using a variety of structures, enabling it
to be tightly appressed (see earlier under remarks for the
sternum). The male abdomen may be held using
prominences, spines, angles and/or small structures on the
base of the coxae of the legs, chelipeds or even third
maxillipeds; or by means of a tubercle on the sternum (on
sternite 5) which fits into a depression (the socket) on the
ventrum of the abdomen (on the distal edge of segment 6).
This special mechanism is called a press-button system
(“bouton-pression” in the original French terminology).
Some species lack any locking mechanism whatsoever
(notably the Mictyridae and some Ocypodidae), but some
may still be able to hold the abdomen more or less tightly
against the sternum using specialised musculature or
abdominal design. Some of course have fully “free”
abdomens (e.g. some Raninidae [except Lyreidinae] and
14
RAFFLES BULLETIN OF ZOOLOGY 2007
Corystidae). While adult female crabs generally do not
have any special mechanism to hold their wide abdomen
tightly against the sternum (effectively “free”), some have
the segments so strongly convex and extensively fused
that the abdomen is effectively one large domed plate
which completely covers the sternum like the lid of a box!
The press-button can remain functional in females of some
families (e.g. Dorippidae), but generally it is represented
only by non-functional corneous scars in ovigerous
females or is completely absent. For example, female
aethrids have a weak but functional press-button system,
while that of female parthenopids is as strong as that of
males. In homolids, there is a similar structure, the outer
edge of sternite 4 of both males and females possessing a
low serrated crest which fits into a slit-like socket on the
outer edge of abdominal segment 6. This structure (which
has been called the homolid press button) functions
exactly like the press-button system of other crabs. The
acquisition of a retaining/locking mechanism may be
regarded as a synapomorphy for the Brachyura.
iphiculids), have their own unique locking system where
the whole margin of the brood pouch is a solid structure,
fused with the lateral edges of the sternum. In preserved
material, we sometimes even need to break the abdomen
to lift it.
The shape of the male abdomen can vary appreciably.
Most male crabs have segments 3–7 forming a triangular
shape, with segments 1 and 2 smaller and narrower
longitudinally. Some, however, have segments 4 or 5–7
markedly narrow transversely, making the distal part very
acute and the abdomen T-shaped (e.g. some
Parathelphusidae and Portunidae). In some, segment 6
may be laterally constricted such that part of the
sterno-abdominal cavity and even the gonopods are
exposed.
Moult lines. All crabs moult, but the “splitting” of the
exoskeleton to enable the new body to extract itself is
achieved in different ways. Most crabs have a lateral
moult line (sometimes called suture) which runs along the
side of the carapace In the Dromiidae, Dynomenidae and
most Eubrachyura the moult suture runs along the lateral
and/or ventral edges of the carapace to the pterygostomial
region and orbits. There have been various descriptive
terms proposed (often “pleural line”), but for convenience,
we here suggest the use of "linea brachyura" for this
feature. In homolids, the lateral moult suture, called “linea
homolica”, is dorsal in position on each side of the
carapace and extends longitudinally across the entire
carapace. These lines are distinct because this is the area
where the carapace is only weakly calcified, appearing
thinner and more translucent than neighbouring areas. It is
not known if these lines/sutures are homologous although
both serve the same function. This is especially the case
with the linea brachyura of podotremes and sternitremes.
Whether these linea are homologous with those in the
Anomura and Thalassinoidea is another question.
Latreilliids have only a partial lateral linea on the anterior
part of the carapace while a few crabs like
hymenosomatids apparently do not have any trace of a
suture. In some hymenosomatids, there are pronounced
grooves on the dorsal surface of the carapace which may
well correspond to the moult suture or “linea” of other
crabs; but we are uncertain how these crabs moult. In the
Homolodromiidae, there is no clear linea, and it is
replaced by a large poorly calcified area on the
branchiostegite. How these crabs moult is not known.
Why do most male and some female crabs need to lock
their abdomens against the sternum? It may be simply
that it is metabolically expedient not to have to maintain
closure using constantly tensed muscles — the whole
point of carcinisation is to reduce the abdomen and close
it against a sternal cavity, thus making the crab more
mobile. Logically the simplest way to maintain this,
when access to the gonopods is not needed, is to have
some form of simple locking mechanism. Female
abdomens are typically broadly expanded for their eggcarrying role, and tend to lie over the sternum rather than
sink into a sternal cavity, and therefore the practicality of
a locking mechanism is challenged. However, there is no
doubt that in male crabs at least, the tightly closed
abdomen serves to protect the vulnerable gonopods from
abrasion or other damage, protecting the male crab's
ability to mate. Wholly marine crabs without a locking
mechanism, like corystids and most raninids, are almost
always burrowing crabs, living in soft substrates like
mud, silt or fine sand. Such soft substrates are unlikely to
damage their chitinised gonopods, and so the absence of
a locking mechanism is not serious. Even terrestrial
intertidal crabs which have no locking mechanism like
mictyrids and some ocypodids also live on soft
substrates. Similarly, cryptochirids, which spend all their
time protected inside coral galls, have no need for a
locking mechanism. Interestingly, male pinnotherids,
have to move from host to host to fertilise the females
and often across hard and rough substrates, have a
press-button lock. All land and freshwater crabs have
well developed press-button locks as they often move
across rough substrates. Why some female crabs need a
locking mechanism is more puzzling. Many crabs have
such large egg masses that it is not possible to hold the
abdomen against the sternum. This is also the case for
parthenopids, so their possession of a well developed
press-button system is curious. It makes sense for some
species which have well developed brood pouches to
have locking mechanisms, but again it is not universal,
Latreilliidae have it, but hymenosomatids and leucosiids
(sensu stricto) lack a lock. Leucosiids (but not the
Sexual dimorphism and sexual characters. Many
species of crabs show sexual dimorphism, with males
being larger, smaller, or possessing special or enlarged
structures. In some species the females are the larger.
Most commonly, males have proportionately much larger
chelipeds or chelae. In some heterochelous crabs, males
have one of their chelipeds extremely enlarged to be used
for courtship.
Males always have only two pairs of gonopods (uniramous
swimmerets or pleopods) which are specially modified for
copulation (most crabs practice internal fertilisation). The
first gonopod (G1) is basically a highly modified pleopod
15
Ng et al.: Systema Brachyurorum Part I
which has been folded or rolled longitudinally to form a
cylindrical tube. The degree of this folding varies; from
incomplete, leaving a prominent longitudinal gap between
the two margins, to having the folds overlapping several
times. The channel thus formed can vary from very wide to
extremely narrow and almost capillary-like. The form of the
G1 varies from broad to very slender, straight to sinuous,
and even strongly recurved. In camptandriids, the tip curves
backwards almost 180°. The tip of the G1 varies from acute
to truncate, and in many terrestrial or semiterrestrial crabs
(Grapsidae, Ocypodidae and Gecarcinidae), the tip is
distinctly pectinated and densely surrounded by long stiff
setae. The distal and subdistal margins can be lined with
spines, various types and lengths of setae, lobes, folds,
special processes, and can even be dilated. The function of
these structures is not known, but it is presumably to help
hold the G1 in position during copulation. In some
freshwater crabs (notably Potamidae and Pseudothelphusidae), the tip or subdistal part of the G1 is so bizarre,
large or swollen that it is impossible for it to be completely
inserted into the vulvae – in these, presumably only the
narrow tip (which may be subdistal) enters. This is also
probably the case with the G1 of ocypodids, grapsids and
gecarcinids. In the camptandriids, some species (e.g. in
Paracleistostoma) have the distal part somewhat swollen,
but as this structure is relatively weakly chitinised, and there
are longitudinal folds, it is probably dilatable, and it may be
expanded during copulation, as is done by many insects.
Since the G1 is formed by folds, it is not rare to find spines
and short setae on the inner surface (channel). Most marine
crabs have chitinised G1s but these are rarely heavily
calcified as well, so they remain soft and still somewhat
flexible. This is not the case with terrestrial and
semiterrestrial crabs (e.g. Ocypodidae, Grapsidae, Gecarcinidae, and many terrestrial Potamidae, Potamonautidae,
Pseudothelphusidae). Their G1s are very stiff, well calcified
or heavily chitinised. Most crabs have the G1 as a single
piece, but in all potamids, potamonautids and some
parathelphusids, it appears effectively “2-segmented”.
Strictly speaking, the G1 does not consist of two segments,
as the basal portion is probably formed by one part of the G1
twisting sharply and forming a transverse or oblique fold.
However, the term “2-segmented” is convenient and is
retained here. In podotremes, the basal part of the G1 has
only one large opening (a single “foramen”) into which both
the penis and G2 are inserted. This is usually not problematic
as the G1 is usually large and the folding incomplete, leaving
a distinct gap between the folds. In the modern crabs
(thoracotremes), the folding is usually more complex, and
the base of the G1 has a separate opening each for the penis
and G2 (two foramina). In some crabs (e.g. some
Portunidae), the opening for the penis is surrounded by a
small but prominent transversely grooved lamelliform plate
which apparently helps guide the penis into the basal G1
opening.
flagellum can be sharp, truncate, bifid, spatulate (some
Potamidae and Potamonautidae) or hooked (some
Eriphioidea). Both segments can be of various lengths. At
the junction of the two segments, there is usually a small
flap which can be cup-like. Sometimes, the flagellum is
absent, and the tip is flattened or concave. In all crabs, the
G2 fits into the internal channel formed by the folds of the
G1; and serves one of two functions, either to guide the
sperm along the G1, or as a piston pump to push the sperm
up the channel into the vulva. Crabs which have very
slender G1s (and very narrow channels) (e.g. Xanthidae
and Pilumnidae) invariably have very short G2s with
cup-like tips. Presumably, the sperm moves up the channel
by capillary action, and the small G2 serves merely to help
move it along. How very long whip-like G2s (e.g. some
Eriphioidea) function is not known. They can enter the
vulvae as fragments of G2s have been found stuck in the
vulva; but it is also possible this is anomalous, with the
elongated G2 staying mostly curled or coiled up inside the
G1 and helping to move the sperm along simply through
increasing the overall surface area when pumping. In the
case of potamids, the study of Brandis et al. (1999)
suggests that it enters the vulva.
What is referred to as spermatheca in the podotrematous
crabs is an internalized structure derived from sternal
modifications of two adjacent segments in females, and is
basically a split between the two plates of the intersegmental phragma 7/8, i.e. one derived from sternite 7
and the other one from sternite 8. This intersegmental or
intertagmal, internal, and paired spermatheca, as a
secondary specialization of the phragma 7/8, is unique to
the Podotremata (see Tavares & Secretan, 1992; Guinot &
Tavares, 2001; 2003; Guinot & Quenette, 2005).
The pleopods of females are branched, setose and carry
the eggs. The fertilised eggs are exuded, and thence
attached to the female's setose pleopods, where she broods
them for several weeks before hatching to release the
planktonic larvae (zoeae).
Development in almost all crabs is via zoeae. The eggs
hatch into first zoeae which typically go through 1–6
instars before becoming a megalopa. Some species have
larger eggs and fewer zoeal stages. Majids in particular,
typically have only two zoeal stages. Some groups have
species in which the typical number of zoeal stages is
reduced, with their zoeae more advanced in form, and
having fewer stages. This is termed semi-abbreviated
development. In extreme cases, there may only be one
zoeal stage that may not even need to feed, relying entirely
on stored yolk inside the body. In a few species, the larval
development is even more truncated, with no free
swimming zoeal stages, and the eggs hatch directly into
megalopae, or even the first crab stage. This is abbreviated
development. Few marine crabs practice abbreviated
development, notable being some species of pilumnids,
dromiids, homolodromiids, freshwater sesarmids and all
true freshwater crab families. Except for the true
freshwater crabs, some freshwater sesarmids, and the
Trogloplacinae (Chasmocarcinidae) in which the eggs
hatch into first crabs (i.e. direct development); all other
The second gonopod (G2) also varies a great deal in form,
from whip-like to sigmoidal (very small, comma-shaped).
The G2 can be much shorter than the G1, or indeed longer.
Often, the G2 is divided into two parts, with a stouter
basal “segment”, and a slender and elongate distal part
(usually referred to as the flagellum). The tip of the
16
RAFFLES BULLETIN OF ZOOLOGY 2007
crabs have at least a short megalopal stage, even if the
megalopa are not planktonic and cling to the mother. Only
in one family, the Hymenosomatidae, are megalopa not
known, with the zoeae metamorphosing directly into first
crab. This is believed to have affected their number of
abdominal segments (they only have six and not the usual
seven). In crabs, segments are usually added as the larval
instars grow, with the final segment added at the
megalopa-first crab moult.
ongoing. In instances when the authors have
manuscripts which will be published soon, we have
cited them as papers in preparation. In some cases, the
comments set out hypotheses for future testing, perhaps
using larval, molecular and/or other methods.
Each family and subfamily has all its synonyms listed.
This is to facilitate cross-referencing. We have not done
this for superfamilies as this will make the work far too
repetitive. Our systematic framework is from superfamilies
down to subfamilies. The format of presentation for each
genus and species is straightforward. For taxa in which
the
International
Commission
of
Zoological
Nomenclature has made a ruling (in the form of a
Direction or Opinion), this is indicated. These rulings are
important as they help fix type species and/or spellings,
gender, authorships and dates of publication. If we have
taxonomic or other notes about the genus and/or species,
we have indicated this with a number in parentheses; and
these are listed at the end of each family. For each genus,
the type species and gender are always specified. In cases
when the classification of a particular species in a genus
is tentative or uncertain, we have placed the genus name
in inverted commas. We also use “?” when we are unsure
of the placement or status of a particular species (e.g.
which genus it belongs to, is it a synonym of another
name, etc.). Primary synonyms are listed, and if a name is
pre-occupied by a senior homonym, this is stated. For
each species, the current generic allocation is used for the
spelling and gender. The genus (and subgenus) the taxon
was originally described in, is then placed at the end of
the name in square parentheses. We have corrected the
suffix of the species name in each case to match the
gender of the genus name. This, however, is only done for
species (and subspecies) we recognise as valid, and not
when the name is invalid or regarded as a junior
synonym. In such cases, we have used the original
spelling. The index prepared here is not comprehensive as
it lists only the recognised supraspecific taxa. In any case,
the pdf document is fully searchable.
In some crabs, the endophragmal skeleton is rather
unusual in that the constituent endosternal and endopleural
plates are all displaced laterally, leaving the central parts
of the crab effectively empty. In the Hymenosomatidae in
particular, this median space is rather large, and this has
apparently allowed some species (e.g. Neorhynchoplax
mangalis) to evolve the habit of ovoviviparity, in which
the fertilised eggs develop inside the large "empty"
median body cavity and are extruded not through the
vulvae but via a tear on the sternal membrane, hatching
into zoeae in the process (Ng & Chuang, 1996).
Setal covering. Many species of crabs have differing
degrees of pubescence on their bodies and appendages.
The “hair” (more accurately called setae) may be soft or
stiff, simple or plumose, or so short that it appears like
pile. The setae may sometimes be so stiff as to be
spine-like, especially on the propodus and dactylus of the
legs. Majids often have hook-like setae which are used for
the attachment of sponges, algae and debris (similar in
action to velcro). This helps in the crab's camouflage. In
other crabs, the longer and/or plumose setae usually gather
dirt and mud which helps obscure the animal's outline.
Softer setae on the legs and chelae have a sensory purpose.
METHODS
One of the major uses for the present list is that it gives an
overview of the members of any given group, and this
hopefully should facilitate and catalyse systematic
revisions and taxonomic studies. While we have taken
care to be as complete and accurate as possible, primary
literature sources should always be checked and verified.
We have used a multitude of literature sources to compile
this list, some original, some secondary, although in most
cases we have tried to verify the accuracy of all entries.
We have not normally considered fossil genera in our
synopsis. Only in a few cases where the synonymy is for
well known extant taxa have we added in the names as
well, for example Palaeopinnixa Via Boada, 1966 (with
Pinnixa) and Carcinoplacoides Kesling, 1958 (with
Libystes), and in such cases, we note that these are names
for fossil genera. We emphasise that the synonymy
concerning fossil taxa is not exhaustive.
The present compilation is more than a simple list.
Whenever possible we have added comments and
discussion to the different taxa when we are aware of
changes and problems. This is done with the primary
aim to inform the reader as to changes which may have
taken place recently, problems that still exist, and
challenges ahead. It identifies numerous nomenclatural
and taxonomic problems that future workers can pursue
and hopefully help resolve. This we hope will help the
reader better understand the complexities involved in
brachyuran systematics, and perhaps help them
formulate hypotheses to test. We have also added points
derived from our own unpublished studies in some
instances so that the reader is aware of what work is still
We have envisaged the present exercise to be in three
parts. The first part is the present checklist. The second
part, which we hope can be ready in several years, is a
detailed synopsis of all superfamilies, families and
subfamilies, with keys and figures. The third part, which
will hopefully will also be ready at the same time, will be
a complete bibliography of all the literature for author and
date citations. While we regret that this bibliography
cannot be ready in time together with the first part (which
would have enhanced its value), practical and logistical
issues pose major constraints. The present list (Part 1) has
already taken us over 10 years to assemble.

The following abbreviations are used: ICZN = International
Commission for Zoological Nomenclature; Code =
International Code for Zoological Nomenclature (1999);
P2–P5 = first to fourth ambulatory legs respectively; G1 =
male first gonopod; and G2 = male second gonopod. Most
of the nomenclatural terms used in this catalogue (e.g.,
nomen protectum, nomen oblitum, nomen nudum, etc.) are
explained in detail in the Glossary of the Code (ICZN,
1999: 99–122) and are not elaborated on here.
Article 23.9.2 are met, and also state that, to his or her
knowledge, the condition in Article 23.9.1 applies. From
the date of publication of that act the younger name has
precedence over the older name. When cited, the younger
but valid name may be qualified by the term “nomen
protectum” and the invalid, but older, name by the term
“nomen oblitum” (see Glossary). In the case of subjective
synonymy, whenever the names are not regarded as
synonyms the older name may be used as valid.”
We have added colour photographs of interesting species
to fill up the spaces between major groups; partly for “eye
relief” and partly to share with the readers how spectacular
some of these taxa are when freshly collected. When the
photographs were by T. Y. Chan or P. K. L. Ng, there are
always preserved voucher specimens in the Raffles
Museum of Biodiversity in Singapore or Muséum national
d'Histoire naturelle in Paris.
Uunder this provision, we have suppressed two names:
Cancer dodecos Linnaeus, 1767 (= Inachus dorsettensis
(Pennant, 1777)), and Cancer pellitus Forskål, 1775
(=Liocarcinus corrugatus (Pennant, 1777). These are both
senior to the names currently used, but have not been used
for at least five decades. It is unfortunate that the rule is
open to subjectivity. There are no types for these species,
but we believe that the descriptions provided by Linnaeus
for them, leave little doubt as to their identities. It seems
that the names were missed inadvertently by early
workers, and the mistake then perpetuated. However, in
the interests of stability, we have decided to maintain the
names under which both have been commonly known.
NOTES ON GENERAL NOMENCLATURE
On ICZN rulings. In many cases, the ICZN has made
specific rulings with regard to type species, incorrect
spellings, and availability of names. These rulings have
been published as a series of Directions and Opinions, and
the revised names and decisions are placed into the
Official Lists. These decisions are binding on all users of
zoological nomenclature, and override normal procedures
as layed out in the formal ICZN Code. Changes will then
only be considered following a new direct application to
the Commission. For example, Miers (1886) selected
Cancer gigas Lamarck, 1818, as the type species of
Pseudocarcinus H. Milne Edwards, 1834. The
Commission (Opinion 85, Direction 37) ruled that this was
correct. However, Desmarest (1858) had in fact earlier
selected Cancer rumphii Fabricius, 1798, as the type
species of Pseudocarcinus. Although the action of
Desmarest (1858) had priority over Miers (1886), Miers’
selection nevertheless stands because of Opinion 85. We
have generally not given full references to ICZN rulings
because they are already compiled by ICZN (1987, 2001).
Type species. Modern authors, when describing new
genera, invariably specifically designate type species. In
fact, under the 1999 Code, new genera (or subgenera)
established without type species after 2000 are regarded as
nomenclaturally invalid. When a genus (or subgenus) has
only one species, we have used two terms, "by monotypy"
and "by original designation". Although neither term
affects nomenclature, we felt it was better to reflect what
the original authors had done. "By monotypy" means that
the original author did not specifically select a type
species but since only one species was mentioned or
listed, it becomes the type species by default. In most
modern papers, authors specifically choose a species as
the type, even when there is only one species, i.e the type
species is "by designation". Article 68.1 which deals with
the order of precedence in ways of fixation of a type
species states that “If one (or more) species qualifies for
fixation as the type species in more than one of the ways
provided for in Articles 68.2–68.5, the valid fixation is
that determined by reference to the following order of
precedence: firstly, original designation [Art. 68.2], then
monotypy [Art. 68.3], then absolute tautonymy [Art.
68.4], and lastly Linnaean tautonymy [Art. 68.5]”.
A note on the 50-year rule of ICZN. The so-called 50
year rule for the reversal of precedence has been
resurrected in a modified form in the recent (1999) Code
as Article 23.9. It states: “In accordance with the purpose
of the Principle of Priority [Art. 23.2], its application is
moderated as follows: 23.9.1. prevailing usage must be
maintained when the following conditions are met:
23.9.1.1. the senior synonym or homonym has not been
used as a valid name after 1899, and 23.9.1.2. the junior
synonym or homonym has been used for a particular taxon
as its presumed valid name in at least 25 works, published
by at least 10 authors in the immediately preceding 50
years and encompassing a span of not less than 10 years.
23.9.2. An author who discovers that both the conditions
of 23.9.1 are met should cite the two names together and
state explicitly that the younger name is valid, and that the
action is taken in accordance with this Article; at the same
time the author must give evidence that the conditions of
A note on emended spellings. With regard to
emendation of genus and species names, we follow the
recommendations of Article 33.2: “Any demonstrably
intentional change in the original spelling of a name
other than a mandatory change is an “emendation”,
except as provided in Article 33.4.” and “33.2.1. A
change in the original spelling of a name is only to be
interpreted as “demonstrably intentional” when in the
work itself, or in an author’s or publisher’s corrigenda,
there is an explicit statement of intention, or when both
the original and the changed spelling are cited and the
latter is adopted in place of the former, or when two or
18
RAFFLES BULLETIN OF ZOOLOGY 2007
more names in the same work are treated in a similar
way.” However, there are two caveats in the Code which
allow some emendations to be used regardless. The two
articles are: Article 33.2.3.1 – “when an unjustified
emendation is in prevailing usage and is attributed to the
original author and date it is deemed to be a justified
emendation.”; and Article 33.3.1 – “when an incorrect
spelling is in prevailing usage and is attributed to the
publication of the original spelling, the subsequent
spelling and attribution are to be preserved and the
spelling is deemed to be a correct spelling.”
due to how the genus name on which the taxon is based is
modified. For example, the raninid subfamily Notopinae
Serène & Umali, 1972, should be spelt as “Notopodinae”
instead, as the name was based on the genus Notopus.
Similarly, the majoid taxon Oncinopidae Stimpson, 1858,
should be “Oncinopodidae” as it was based on Oncinopus;
Anomalopinae Stimpson, 1871, should be “Anomalopodinae” as it was based on Anomalopus; and Leptopinae
Stimpson, 1871, should be “Leptopisinae” as it was based
on Leptopisa.
A note on the retention of junior suprageneric names.
The new Code has a useful provision for suprageneric
names that helps maintain stability. Article 35.5 states that
“Precedence for names in use at higher rank. If after 1999
a name in use for a family-group taxon (e.g. for a
subfamily) is found to be older than a name in prevailing
usage for a taxon at higher rank in the same family-group
taxon (e.g. for the family within which the older name is
the name of a subfamily) the older name is not to displace
the younger name.” This was done specifically to
minimise confusion when family level taxa are raised to
superfamilies, or subfamilies to families, and taxonomic
compositions change. Two cases best demonstrate how
this rule is to be used (and not to be used).
On the gender of generic and subgeneric names. There
has often been confusion over the correct ending of some
species names because of not knowing, or not caring, about
the gender of the genus. The Code has clear guidelines for
this (Article 30.1), though there are still enough exceptions
to sometimes make things confusing. The Code also
provides some strict rules that must be used to fix some
spellings. For names ending in -ops, the gender must be
masculine, regardless of the origins or the author’s intent
(Article 30.1.4.3). For names ending in -opsis, the gender
must be feminine (Article 30.1.2). For names ending in -ites,
-oides, -ides, -odes, -istes, the gender has to be masculine
(Article 30.1.4.4). General guidelines (for crab names at least),
are that names ending in -ceras, -mon, -nema, -odon, -soma,
-stoma are neuter; names ending in -ella, -inus, -merus,
-carpus, -somus, -stomus are masculine; and names ending
in -anas, -caris, -gaster, -lepis, -ella, , -plax are feminine.
In the recent classifications (see Martin & Davis, 2001),
the family Panopeidae Ortmann, 1893, is recognised for
two subfamilies, Panopeinae Ortmann, 1893, and
Eucratopsinae Stimpson, 1871. Before the new Code, the
family would have to known as Eucratopsidae on the basis
of precedence as it was published in 1871, 22 years before
Panopeidae. But because Panopeidae is a much better
known name, retaining this name for the family makes
more sense than using Eucratopsidae. Martin & Davis
(2001) rightly used this provision to keep Panopeidae.
There are some “atypical” cases. Cryptocoeloma is
neuter following a ruling by the Commission (Opinion
1554). Gonioinfradens is masculine, as the gender of
“dens” (or tooth) is masculine. Ocypode and Panope are
feminine; whilst Sesarma is neuter. Some authors derive
their names from arbitrary combinations of letters, or
from non Latin or Greek roots. In such cases, they can
specify the gender. For example, while Tanaoa and
Urashima are masculine, Tokoyo is feminine.
The problem with Menippidae Ortmann, 1893, Eriphiidae
MacLeay, 1838, and Oziidae Dana, 1851, is different.
Citing Article 35.5 of the Code, Martin & Davis (2001:
53) argued that the name Menippidae must be used instead
of Oziidae or Eriphiidae. However, they apparently did not
realise that the articles in the 1999 cannot be applied
retrospectively. The name Menippidae had been
synonymised with Oziidae by Holthuis (1993: 619) who
commented that “The present family is often indicated as
Menippidae Ortmann, 1893, but as the family contains
both the genera Menippe and Ozius, the correct name of
the family name is Oziidae Dana, 1852 (sic).” Ng (1998:
1050) subsequently showed that Eriphiidae was an older
name and had priority over both Oziidae and Menippidae.
The ICZN (1999) Code (and Article 35.5), valid for
actions from 2000, does not apply to both Holthuis’
(1993) and Ng’s (1998) decisions; and the arguments in
the Article are not applicable in the manner argued by
Martin & Davis (2001). Fortunately, in the present
reappraisal of eriphioid classification, the Menippidae,
Eriphiidae and Oziidae are regarded as separate families,
diffusing any possible dispute over the use of these names.
It is also useful to point out that in the case of a subgenus,
its gender may be different from that of the genus. Consider
the
macrophthalmid
subgenus,
Macrophthalmus
(Chaenostoma) Stimpson, 1858. The gender of
Macrophthalmus Desmarest, 1823, is masculine, while
Chaenostoma is feminine. In this synopsis, whenever a
subgenus name is used together with the genus name, and
the gender is specified, it is taken to be that of the subgenus.
In the above case, the gender for Macrophthalmus
(Chaenostoma) Stimpson, 1858, is cited here as feminine.
However, when we use a species name as well, the gender
of the species must agree with the genus. For example,
Macrophthalmus (Chaenostoma) dentatus Stimpson, 1858.
A note on the suffix for some suprageneric names. The
challenges of the Latin language are such that in
establishing subfamilies or families, authors sometimes
use the incorrent suffix for these taxa. This is primarily
19
Ng et al.: Systema Brachyurorum Part I
A note on incertae sedis and non-brachyuran names. A
good number of taxa cannot be determined with any
accuracy and are here regarded as nomina dubia. They are
valid taxa, but have been diagnosed so briefly that we
really cannot be certain of their identity. In most cases, we
have been able to attribute them to a family or sometimes,
even subfamily; but we must emphasise that this should be
regarded as provisional. Only a re-examination of the
types will resolve these problems.
carcinologists now cite the species as “Scyllarides haani
(De Haan, 1841)”. The Code (Article 50,
Recommendation 50A) states that authorship should
belong only to those directly responsible for the name, and
for satisfying the criteria that make the name available. In
a new work, the authorship should be explicitly stated, but
for older works it still often remains unclear how to
determine the individual responsibility of each putative
author. In these cases (sometimes contentiously), we have
used our best judgement to decide on authorship.
Two other names need mention. One is a Forskål name,
Cancer antennatus Forskål, 1775. Forskål (1775) wrote:
“CANCER ANTENNATUS; brachyurus, thorace
subovato, antennis triplo longioribus; chelis cuneiformibus. DESCR. Ungue brevior: cinereus, nebulis
nigris. Antennae seraceae, rufescentes, thorace triplo
longiores: rarus in brachyuris character. Frons obtusa,
repanda. Oculi breves, obtusi. Thorax planiusculus,
ovatus, basi truncates. Chelae compressae, inermes, subtus
rubentes punctis obscurioibus; pedes reliqui sine chelis.
Carpi femoribus longiores, introrsum bidentati. Cauda
ovata, inflexa, thoracis latutudine, utringue ciliato-dentata.
Sués, habitans in foraminibus Spongiae Offic. violaceae.
Quotquot vidi foemellae errant.” Brief though this is, it
leaves little doubt in our mind that Cancer antennatus
Forskål, 1775, is in fact a species of porcellanid crab.
Similarly, the species originally identified as Parthenope
dubia Fabricius, 1798 (= Parthenope dubia Weber, 1795,
nomen nudum), is also a porcellanid, probably a species of
Pisidia. The type specimens in the Copenhagen Museum
are in rather poor condition but are clearly porcellanids.
Another complex (and often emotional issue) involves
crediting authorship to suprageneric taxa like families. The
most unfortunate must surely be the case of H. Milne
Edwards (1834, 1837) who developed a very
comprehensive classification of the Brachyura, including
names for many groups that carcinologists still recognise
today, but used mostly French vernacular names. Under
the Code, names are normally only valid when they are in
Latin or latinised. As such, although H. Milne Edwards
was the first to recognise and provide a diagnosis for most
of the groups, his failure to use a Latin name means that
many of his “families” are now credited to MacLeay
(1838) — despite the fact that MacLeay himself attributed
the names and concepts to H. Milne Edwards! To further
complicate matters, some of H. Milne Edwards' ideas were
actually derived from those of Desmarest and Latreille,
who were often even more vague in recognising groups
which they did not "formally name in Latin". There are
exceptions however — Latreille (1802) used the terms
“Cancérides” (as French vernacular, with an accent) as
well as “Cancerides” (as a Latin name) in the same paper,
so it is reasonable to deduce that he differentiated between
the two, and in contrast to most publications, the
authorship of Cancridae should be attributed to Latreille
(1802) rather than, as is more common, to MacLeay
(1838). To resolve some of these problems, and to ensure
there is less confusion in the future, Article 11.7.2 of the
Code states that “If a family-group name was published
before 1900, in accordance with the above provisions of
this article but not in latinized form, it is available with its
original author and date only if it has been latinized by
later authors and has been generally accepted as valid by
authors interested in the group concerned and as dating
from that first publication in vernacular form.” While we
follow this rule, we have kept in mind that the terms of
this article are not retroactive. As such, for most taxa we
maintain the current widely accepted authorships
(unfortunately for H. Milne Edwards). Article 11.7.2
should only be applied when new cases are discovered.
NOTES ON AUTHORSHIPS OF TAXA
Citation of authors. The correct author citation has
sometimes been confusing, particularly in some older
papers where the author cites others as the source of the
name without clearly stating if they had contributed to the
description (see Ng, 1994). When a purported author is
clearly not a carcinologist or scientist, they can be easily
disregarded. However it becomes more difficult when this
is not the case. Ng (1994: 510) commented: “… citing just
an authors's name after the new species name does not
make clear that the description is the work of that author.
Henri Milne Edwards (1834) in his "Histoire Naturelles
des Crustacés" in several instances used the author's name
"Lamarck" or "Latreille" after a new species name, usually
with a footnote "coll. du Muséum". It proved later that in
such cases, H. Milne Edwards had used names written on
the labels of the type specimens or in manuscripts by
Lamarck or Latreille, who, however, never published that
name or the description of the species name H. Milne
Edwards used. H. Milne Edwards used these old
manuscript names and provided the descriptions himself.
Many later authors cited the species name with Lamarck
or Latreille as authors. The Code effectively did away with
this practice. This is the origin for Article 50a. Similarly,
De Haan (1841), in his Fauna Japonica published a new
scyllarid lobster species “Scyllarus Haani v. Siebold”.
Von Siebold had suggested this name, and asked De Haan
to use it. As the description was entirely by De Haan,
Spelling of author's names. The names of a number of
important carcinologists have been variously cited through
time, and we here recognise the need to standardise usage
and even spelling. For example, should one cite De Brito
Capello or Brito Capello, Marion de Procé or De Procé,
Saussure or De Saussure, De Lamarck or Lamarck,
Forskål or Forsskål, MacLeay or Macleay? There is often
no clear right or wrong answer. Our decisions have been
based on common and/or widespread usage, and/or advice
on individual language conventions.

RAFFLES BULLETIN OF ZOOLOGY 2007
For the father and son team of Henri and Alphonse Milne
Edwards, we follow Forest (1996), Forest & Holthuis
(1997) and Fransen et al. (1997) in using “Milne Edwards”
for the father (Henri) and “Milne-Edwards” for the son
(Alphonse). For French names, the honorific “De” is left
out, because otherwise widely used names like Lamarck
etc. would also be required to have this prefix. There is
also a problem with the correct citation of the French
name “Guérin-Méneville”. As noted by Evenhuis (2003:
16, footnote), “Guérin took on the honorific suffix “Méneville” to his surname in 1836, after his authorship of
the EM [Encyclopédie Méthodique] was completed.”. As
such, for all species described by Guérin up to 1836, we
simply cite Guérin as the author, whilst for all taxa
described from 1836 onwards, we use Guérin-Méneville.
With regards to some Dutch names, particularly well
known carcinologists such as De Haan and De Man,
Charles Fransen (in litt. to the second author) writes:
“According to the Dutch grammar the official rules are the
following: The preposition such as "van der" or "de" etc. is
written with a capital if no first name or initials are used. J.
G. de Man; Johannes Govertus de Man; but Mr. De Man,
and Phricothelphusa callianira (De Man, 1887). In the
references it should be: Man, J. G. de, 1900. In the Dutch
speaking part of Belgium, the situation is different. Here
they always use the original spelling of the name. So it
will be Sammy De Grave and in references it will be: De
Grave, S., 2000”. In Fransen et al. (1997), the incorrect
lower case “de” was used for these names. For the German
equivalent “von”, we follow their convention in using the
term, i.e “von Hagen” or “von Sternberg”. We use
MacLeay instead of Macleay following Ng & Ahyong
(2001). The name of the Swedish explorer, Peter Forskål
is problematic. Wolff (1993) argues that as a Danish
name, it should be spelt with two “s”, i.e. as Forsskål,
especially since he signs his name this way in his letters.
However, all of Forskål’s publications have his name
written with only one “s”, and we therefore follow this
convention as it was obviously with Forskål’s agreement.
For workers of Chinese or Vietnamese descent, the family
name is the first name, and it is used here regardless of
intent or convenience. For example, a 1969 paper on
sesarmid larvae by Soh Cheng Lam should be cited as
“Soh, 1969” rather than the more often cited “Lam, 1969”.
A note on the names established by Weber (1795). In
the 1790s the naturalist Daldorff collected many insects
and crustaceans from India and Sumatra, and though he
did not publish his own results, his specimens were
deposited in the Kiel Museum (see Fransen et al., 1997).
Weber (1795) and Fabricius (1798) published several
similar generic names both using Daldorff’s material and
his manuscript notes. Typically the same names were used
in both Weber’s and Fabricius’s works, in the same order,
and generally with the same spelling. Weber’s (1795)
generic names cause some problems because, under the
Code (Article 12.2.5), a genus name from that era can be
regarded as valid if it lists the valid constituent species,
even if there was no accompanying description for the
genus. For example, Ocypode Weber, 1795, was listed
with three species: O. ceratophthalmus (clearly the species
of Pallas, 1772, described in Cancer), O. quadratus
(clearly the species of Fabricius, 1787, also described in
Cancer), and O. rhombea Weber, 1795, which was a
nomen nudum (Ocypode rhombea was only validly
described by Fabricius in 1798). Cancer ceratophthalmus
Pallas, 1772, was subsequently selected as the type
species. Thus, in accordance with the Principle of Priority,
Weber’s genus names should be regarded as the oldest
available names applied to these taxa.
On authors with the same family names. There are
several cases where different taxa have been described by
different scientists with the same family name. The case
for Henri Milne Edwards and Alphonse Milne-Edwards is
perhaps best known. As both were responsible for
describing many new taxa, their family name is always
preceded by their first initial. In most cases, however, one
researcher dominates. In the case of Sakai, the father,
Tune, is responsible for the majority of the brachyuran
crab species named, while his son, Katsushi, has named
many fewer (at least so far). The same is true of the first
author (P. K. L. Ng), whose student, N. K. Ng (unrelated),
has also published a number of new taxa. In such cases,
this study keeps the family name for the author who has
described significantly more new taxa (e.g. Medaeus
serratus Sakai, 1965, and Parathelphusa reticulata Ng,
However, the Nomenclator Entomologicus of Weber
(1795), termed a ‘miserable little book’ by Holthuis
(1959), had been almost completely overlooked in Europe
for more than 150 years, and for all that time Fabricius
(1798) had been considered the author of the generic
names in question. However, Sherborn (1902: 312) and
Rathbun (1904) both drew attention to Weber, and this is
the reason why genera such as Dromia and Parthenope
were credited to Weber (1795) and not Fabricius (1798) in
American publications. Mary Rathbun brough the matter
to the attention of the ICZN who rendered an opinion in
1938 (ICZN, 1938, Opinion 17). In Opinion 17, aptly
titled “Shall the genera of Weber, 1795, be accepted?” (p.
40), the ICZN voted “yes” (12 Commissioners agreeing, 1
disagreeing, and 2 not voting) with the following
comments which are worth citing in verbatim “The
question at issue is not whether this Nomenclator
1990a) and for the other author, his or her personal initials
are added (e.g. Pinnotheres taichungae K. Sakai, 2000,
and Xenograpsus testudinatus N. K. Ng, Huang & Ho,
2000). This makes for a less cumbersome citation. We do
not, however, discriminate between authors that were not
contemporaries – the decades separating them making this
sufficiently obvious (e.g. H. Lucas of the 1800s versus the
J. S. Lucas of the 1980s). Similarly, we do not use the
term “Junior” or “Jr.” when denoting a younger member
of the family, especially since the older ones have no
history with carcinology (e.g. no one cites “Chace Jr.”).
However, in cases where one family name is shared by
several carcinologists, we have no choice but to cite them
separately, e.g. S. H. Tan, C. G. S. Tan and L. W. H. Tan.
NOTES ON SOME PAPERS OF
NOMENCLATURAL SIGNIFICANCE
21
Ng et al.: Systema Brachyurorum Part I
represents a method of publication which is to be
recommended as an example to be followed by other
authors, nor does the question at issue involve any
relations existing between Weber and Fabricius, nor the
point as to whether Fabricius approved or disapproved of
what Weber did. On the contrary, to take a concrete case,
the question is whether, for instance, Weber’s citation of
Symethis with only one type species, namely, Hippa
variolosa Fabricius as given in Fabricius’ Entomologia
systematica entitles this genus Symethis to be considered
under Art. 25 from the 1795 date. This question, which is
taken as an example, the Commission must answer in the
affirmative, with, however, the caution to workers that
since Weber used many nomina nuda, care should be
exercised not to be misled into error in taking any of his
1795 specific names followed by the letter “S” as basis for
work, but, on the contrary, all these names are to be
ignored as far as this Nomenclator is concerned.” (p. 42)
(see also van Cleave, 1943).
problematic. Latreille did not indicate if it was the same as
Calappa lophos (Herbst, 1782) and as such must be
regarded as a new name. What his species actually is will
require a re-examination of the specimen in question. In a
recent revision of the species, Lai et al. (2006) showed that
the Indian Ocean had three species which had been
confused under C. lophos. Latreille’s name is here placed
under the synonymy of Calappa lophos (Herbst, 1782).
Latreille, in Milbert (1812: 275) described a group of
crabs he noted were what Lamarck referred to as “grapse”,
and described their general colour and features. He then
added “Ce sont le grapse de M. Lamarck. Je mentionnerai
le grapse á pinces rouge (grapse erytrhocheles); le grapse
rayé de blanc (grapse albo-lineatus); le grapse tuberculé
(grapse tuberculatus), et une espèce qui, quoiqui petite,
est néanmoins digne d’attention: c’est le grapse damier
(grapse tessellatus)”. Latreille’s use of “grapse" is here
regarded as a valid use of a genus name, although his
spelling is incorrect. In this paper, Latreille usually makes
it clear when he is using a French vernacular name or a
scientific one, by always italicising the latter (as we do
today). These scientific names are clearly used as a
binominal combination as prescribed by the Code.
Although Latreille used lower case when he named his
genera, this is not a problem under the Code. As these four
species are generally defined by their colour and shape,
under Article 12.1 (for names published before 1931), they
can all be regarded as available names. Article 12.3 has a
list of items that it states do not qualify as a description,
definition or indication, and colour is not among them. In
any case, one of these names, Grapse tessellatus, is today
recognised as a valid species of Lybia, and credited to
Latreille (1812) [Direction 36]. There is thus no reason not
to also recognise as valid the other three names in this
paragraph. Grapse albolineata Latreille, in Milbert, 1812,
is senior to Grapsus albolineatus Lamarck, 1818, but it
does not change the understanding of the species. Grapse
tuberculatus Latreille, in Milbert, 1812, is a senior
synonym of Plagusia tuberculata Lamarck, 1818. The
taxonomy of this species is also unaffected; in any case,
this name has been synonymised with Plagusia squamosa
(Herbst, 1790) (see Schubart & Ng, 2000). Grapse
erytrhocheles Latreille, in Milbert, 1812, is a problem, as
we are not sure which species he was referring to. It may
be a Geograpsus species or even a species of gecarcinid. It
is here regarded as incerta sedis in the Grapsidae.
Lipke Holthuis subsequently submitted a series of
applications to the ICZN which effectively resolved most
of the outstanding brachyuran problems, in favour either
of Weber (1795) or Fabricius (1798). The only unsolved
case was that of Orithuja Weber, 1795, versus Orithyia
Fabricius, 1798. This problem will have to be resolved by
the ICZN later (see under Orithyia).
A note on the type species designations by Latreille
(1810). In a little known paper, Latreille (1810) selected
what he called “genotypes” for many genera described up
to that time. The names are listed in Latin after the
vernacular name, and his designations are considered
valid. While not all his designations are clear cut (not at
least by modern standards), the ICZN made a ruling in
1938 that validates all the actions made in this paper
(Opinion 11) (see also Mutchler, 1931).
A note on Latreille, in Milbert (1812). The publication
of Milbert (1812) was an account of a trip to the Indian
Ocean. In Chapter 5 of this book, “Crustacés et Insectes”,
Milbert comments (p. 270): “Voici quelques notes que
m’a fournies le savant M. Latreille, sur le différents
crustacés de l’Ile-de-France” (p. 272). This makes it clear
that Milbert was reproducing the notes provided to him by
Latreille, and as such, the authorship for the new species
listed should be cited as “Latreille, in Milbert, 1812” (see
Cleva et al., 2007).
A note on the type species designations by H. Milne
Edwards (1836–1844). Although H. Milne Edwards did
not indicate the type species for genera in his “Histoire
naturelle des Crustacés”, his subsequent work addressed
many of these problems. In his contribution to Cuvier’s
“Règne Animal”, H. Milne Edwards published a series of
plates, with notes, that represent valid type indications of
genera (as evident from his detailed title, see below).
However, these plates were issued in different parts,
starting in 1836 and ending in 1844, and are not
necessarily in consecutive order. Cowan (1976: 60,
Appendix 8) provided details for the precise date of issue
of each of the crustacean plates.
For many of the names, Latreille, in Milbert (1812)
indicated the taxon was from Linnaeus, Fabricius or
Herbst. Some names, however, do not carry any such
indication, and must be regarded as new. These are:
Cancer impressus, Cancer lividus, Cancer miliaris,
Cancer cupulifer (p. 273), Cancer hispidus (p. 274),
Grapse albo-lineatus, Grapse erytrhocheles, Grapse
tuberculatus, Grapse tessellatus, Calappa lophos (p. 275),
Calappa depressa, Dromia fallax (p. 276), Portunus
tranquebaricus, Matuta lunaris (p. 277), and Parthenope
spinimana (p. 278). One name, Calappa lophos, is slightly

RAFFLES BULLETIN OF ZOOLOGY 2007
On Latreille (1825) and Berthold (1827). In a poorly
known paper, Latreille (1825) (not to be confused with his
paper in Encyclopédie Méthodique, 1825–1828) published
a key to groups of crabs, and used many names for the
first time. However, most of the names used were clearly
in the French vernacular, not only in the way they were
written, but also in his use of accents for some names. The
names he used and the pages they appeared in are as
follow:
“OCYPODE,
GÉLASIME,
MICTYRE,
PINNOTHÈRE, GÉCARCIN, CARDISOME, UCA,
PLAGUSIE, GRAPSE, MACROPHTHALME, RHOMBILLE,
TRAPÉZIE, MELIE, TRICHODACTYLE, TELPHUSE,
ERIPHIE (p. 269); PILUMNE, CRABE, TORTEAU,
PIRIMÈLE, ATÉLÉCYCLE, PODOPHTHALME, LUPE,
CHEIRAGONE, PORTUNE, THIA, PLATYONIQUE (p.
270); MATUTE, ORITHYIE, CORYSTE, LEUCOSIE,
HÉPATIE, MURSIE, CALAPPE, AETHRA (p. 271);
PARTHENOPE, EURYNOME, MITHRAX, HYMÉNOSOME, PISE, STÉNOCIONOPS, MICIPPE, MAÏA, STENOPS,
HYAS, HALIME, CAMPOSCIE, INACHUS, STÉNORHYNQUE, LEPTOPODIE, PACTOLE, LITHODE (p.
272); DROMIE, DYNOMÈNE, HOMOLE, DORIPPE,
RANINE (p. 273)”. There is not always consistency,
however. On page 269, he writes “RHOMBILLE (ou
Gonoplace)”, and on page 270, he writes
“PLATYONIQUE (portumnus, Léach), Polybie (Léach)”,
suggesting he treats the names of Leach separately, but he
nevertheless still uses “Polybie” instead of Polybius.
Should the names Gonoplace, Portumnus and Polybie be
regarded as properly latinised names? On the available
evidence, they should not be available under the Code as
they are not latinised (Article 11.2). Berthold (1827), on
the other hand, made a German translation of Latreille
(1825), but treated the names differently. The names he
used, and the pages on which they appeared, are as follow:
“Ocypode, Gelasima, Mictyris, Pinnotheres, Gecarcinus,
Cardisoma, Uca, Plagusia, Grapsus, Macrophthalmus (p.
254), Gonoplax, Trapecia, Melia, Trichodactylus,
Telphusa, Eriphia, Pilumnus, Cancer, Pagurus, Pirimela,
Atelecyclus (p. 255), Podophthalmus, Lupa, Cheiragonus,
Portunus, Thia, Platyonichus, Matuta, Orithyia, Corystus,
Leucosia, Hepatus, Mursia (p. 256); Calappa, Aethra (p.
257); Parthenope, Eurynome, Mithrax, Hymenosoma,
Pisa, Stenocionops, Micippa, Maia, Stenops, Hyas,
Helimus,
Camposcia,
Inachus,
Stenorhynchus,
Leptopodia, Tactolus, Lithodus, Dromia, Dynomene (p.
258); Homola, Dorippe, Ranina (p. 259)”. There is little
doubt that Berthold has used scientifically correct latinised
names, however most are still also not available as there is
no diagnostic indication of any sort given, and no species
were included (Article 12). Four names however require
special comment: Trichodactylus, Melia, Cardisoma and
Trapecia.
Trichodactylus fluviatilis Latreille, 1828).
(2) Melia is today attributed to Latreille, 1827. Authors
note that since Berthold’s work was a translation of
Latreille (1825), the name should be attributed to Latreille.
This is not correct (see comments on citations). As
discussed above, Berthold changed Latreille’s work in
some places. Melia Berthold, 1827, is available as there
was a reference to Grapsus tesselatus of Latreille’s
Encyclopédie Méthodique (Berthold, 1827: 255, footnote),
which becomes the type species by monotypy. Grapsus
tesselatus was actually validly published earlier by
Latreille, in Milbert (1812) (genus incorrectly spelled as
“Grapse”). In any case, Melia Berthold, 1827, is a junior
homonym of Melia Bosc, 1813 (Crustacea). Lybia H.
Milne Edwards, 1834 (type species Grapse tessellatus
Latreille, in Milbert, 1812) is the valid available name.
(3) For Cardisoma, Berthold mentions two species: “von
Cancer Guanhumi von Marcgrave, und Cancer carnifex
von Herbst” (Berthold, 1827: 254, footnote). This makes
the name available under Articles 11 and 12 of the Code.
At present, Cardisoma is attributed to Latreille, 1828 (type
species Cardisoma guanhumi Latreille, 1828, designation
by H. Milne Edwards, 1838). Cardisoma Berthold, 1827,
therefore has priority. Also, while the species guanhumi is
today attributed to Latreille (1828) (as Cardisoma), since
Berthold (1827) uses the name Cancer guanhumi and
refers to Marcgrave, he was actually the first to validate
the species name. Either Cancer guanhumi Berthold,
1827, or Cancer carnifex Herbst, 1796, can be the type
species of Cardisoma Berthold, 1827.
(4) The genus Trapezia is at present attributed to Latreille,
1828 (type species Trapezia dentifrons Latreille, 1828,
designation by Desmarest, 1858). Berthold (1827: 255,
footnote) uses the name Trapecia and refers to pl. 47, fig.
6 and pl. 20, fig. 115 in Herbst. These figures are referred
to in Herbst as Cancer rufopunctatus Herbst, 1799, and
Cancer glaberrimus Herbst, 1790, respectively. Cancer
rufopunctatus is today in the genus Trapezia (family
Trapeziidae) while Cancer glaberrimus is in the genus
Tetralia (family Tetraliidae). As such, Trapecia Berthold,
1827, is an available name under Articles 11 and 12 of the
Code, and either Cancer rufopunctatus Herbst, 1799, or
Cancer glaberrimus Herbst, 1790, can be the type species.
It makes little sense, however, for Trapecia Berthold,
1827, to replace Trapezia Latreille, 1828; Cardisoma
Berthold, 1827, to replace Cardisoma Latreille, 1828; and
Cancer guanhumi Berthold, 1827, to replace Cardisoma
guanhumi Latreille, 1828. All these names have a long
history of use since the mid-1800s. Trapezia Latreille,
1828, it is also the type genus of the Trapeziidae, so a
change in spelling of the family name as well is
undesirable. To our knowledge, no one has attributed these
taxa to Berthold (1827). We therefore invoke Articles
23.9.1 and 23.9.2 of the Code to have these names
suppressed. Article 23.9.1 requires that the name in
question must have been used in “at least 25 works,
published by at least 10 authors in the immediately
preceding 50 years and encompassing a period of not less
(1) In using the name Trichodactylus, Berthold (1827:
255, footnote) mentions “Telphusa ? quadratus Latreille”
from the Paris Museum. This name, to our knowledge, has
never been published. There is no description (other than it
was from freshwater), and the name is thus a nomen
nudum. As such, Trichodactylus Berthold, 1827, is not an
available name under the Code. Trichodactylus is at
present attributed to Latreille, 1828 (type species
23

than 10 years”. This can easily be demonstrated as these
taxa have been revised in recent years. For Cardisoma
Latreille, 1828, and Cardisoma guanhumi Latreille, 1828,
see Türkay (1970, 1974) and Ng & Guinot (2001). For
Trapezia Latreille, 1828, see Castro et al. (2004).
On the papers of William Stimpson on Asian crabs.
The series of papers by Stimpson (1857, 1858a–d, 1859)
on the Indo-West Pacific fauna has been extremely
important to brachyuran systematics for the region, even
though what were intended to be preliminary descriptions,
are brief and without figures. Unfortunately, much of the
material on which these papers were based was destroyed
in the great Chicago fire (see Evans, 1967; Deiss &
Manning, 1981; Manning, 1993a; Manning & Reed,
2006), and the detailed studies Stimpson had hoped to
conduct never materialised. This has become a major
obstacle in many studies. Fortunately, a good part of his
manuscript was subsequently prepared for press by Mary
Rathbun, culminating in the publication of Stimpson
(1907). Recently, Vasile et al. (2005) did an excellent
review of Stimpson’s landmark explorations and
reproduced his old papers. This important volume should
be consulted by any scholar of Asian Brachyura.
One additional point is whether the names of Berthold
should be regarded as his, or Latreille’s. After all, it was
translation. Still, Berthold did change the way the names
were spelt and used, and also added new notes in some
places. Following the Code strictly, the names should be
attributed to Berthold alone (see Ng, 1994; Citations of
Authors section above).
A note on the type species designations by Desmarest
(1858). In a very poorly known paper, E. Desmarest
(1858) listed and discussed the various brachyuran genera
known to that time. This paper has been missed by almost
all workers. As a brachyuran author E. Desmarest is
himself not well known, and not to be confused with the
better known A. G. Desmarest. In treating a genus, E.
Desmarest would frequently give the number of species he
regarded as belonging to it, or even list their names. In
some cases, he would comment that a particular species is
the type. This action is valid under current nomenclatural
rules, except in cases where a species was not originally
included in that genus. Unfortunately, because Desmarest
(1858) has been missed by most authors, it creates
problems for subsequent type designations, some of which
have been generally accepted by modern carcinologists.
A note on Rathbun (1893). Rathbun described six new
genera (Ericerus, Erileptus, Oediplax, Cryptophrys, Scleroplax and Opisthopus) and 46 new species (Ericerus
latimanus, Podochela tenuipes, Podochela (Corhynchus)
mexicana, Podochela (Corhynchus) lobifrons, Erileptus
spinosus, Anasimus rostratus, Inachoides magdalenensis,
Cyrtomaia smithi, Collodes tenuirostris, Euprognatha

Cymopolia fragilis and Cymopolia zonata) in a major
paper on American crabs in the Proceedings of the United
States National Museum, and the date for this is generally
given as 1893. However, the bound volumes make it clear
that the publication was actually only released in 1894.
Her publication should thus be dated as 1894 (Rathbun,
1894a). One species described by her, Pinnixa
californiensis, has not been treated in most studies. It is
listed here but its identity and generic affinities need to be
re-examined.
A note on the dates of taxa published from the
“Voyage au Pôle Sud”. The authors and dates of the new
species described by J. B. Hombron, H. Jacquinot, H.
Milne Edwards and H. Lucas from the important “Voyage
au Pôle Sud” were detailed in an important paper by Clark
& Crosnier (2000), and many of the uncertainties clarified.
Holthuis (2002) added to their comments and made
several amendments. The challenge has been that many of
these species had been first validated in plates published
over a number of years by Hombron & Jaquinot (1842–
1854), with more detailed written accounts by Jacquinot &
Lucas (1853). Some species had also been published by H.
Milne Edwards & Lucas (1841). The problems were
compounded by the fact that the “original” version of the
paper of Jacquinot & Lucas (1853) had only had H. Lucas
as the author (see Holthuis, 2002). Clark & Crosnier
(2000) and Holthuis (2002) are followed for the
authorship and dates of the taxa described in this
important voyage. If there is conflict, we follow the
interpretation of Holthuis (2002).
A note on Lanchester (1901). During the early 1900s
Lanchester described a number of new taxa from Malaya
in a paper in the Proceedings of the Zoological Society of

socius. Most authors attribute the year of this publication
as “Lanchester (1901)”, but this is incorrect. The
December 1901 issue of the Proceedings of the Zoological
Society of London was actually published only in 1902.
The various new taxa that Lanchester described in this
publication should thus be cited as 1902.
illustrations or photographs to show how his decisions
were derived. This makes it impossible to understand why
new ranks or new taxa are needed, and makes his work
very vulnerable to criticism. To be fair, a good number of
Števi’s taxa are for very “apomorphic” genera which
have been difficult to classify, and in a number of cases
we accept and recognise Števi’s new categories as
valid. However, in many other cases his decisions were
clearly based on a misinterpretation of character states,
and we cannot accept them. We discuss this on a case by
case basis within the body of the list.
A note on Nobili (1905) and Nobili (1906a, b). Nobili
published a number of papers on the fauna of the Middle
East, and there is sometimes confusion over the dates. In
his first paper published in May 1905, Nobili (1905)
validated only nine names from the Persian Gulf, viz.
Leucosiidae: Leucosia hilaris (now in Urnalana), Philyra
granigera; Galenidae: Halimede hendersoni; Pilumnidae:
Actumnus bonnieri, Pilumnus propinquus; Portunidae:
Neptunus (Hellenus) arabicus (now in Portunus
(Xiphonectes)), Thalamita giardi; and Pinnotheridae:
Ostracotheres spondyli, Pinnotheres perezi. More species
were described from the Red Sea in his preliminary paper
of 1906a; which was elaborated upon in Nobili (1906b).
While we accept that it is necessary to recognise new
suprageneric categories as part of an evolving
understanding of brachyuran relationships, we have
reservations with how Števi has done it. We prefer to
take a more conservative approach, allowing these new
taxa to be proposed by expert workers as a reflection of
their own in-depth knowledge of their group. We believe
that accurately understanding characters across a wide
spectrum of species and genera is imperative before
establishing a new suprageneric taxon.
Notes on Števi’s (2005). While we respect the long
years of endeavour that Zdravko Števi spent working
on his comprehensive suprageneric reclassification, we
find ourselves rather critical of the resulting publication.
Unlike most authors before him, Števi has showed little
restraint in reaching decisions regarding the formation
and membership of new taxa. It seems that he did not
hesitate to establish a new tribe, subfamily, family, or
even superfamily, for any taxon he could find that has a
suite of “unusual” characters. His justification for this
approach, is that the slow pace of decision making in
regard to higher level systematics, through much of the
last century, has actually hampered the science of
carcinology. In reviewing parts of what Števi called his
“magnus opus”, the authors and other colleagues often
strongly disagreed with his decisions, or urged a more
cautionary approach. Nevertheless, Števi’s (2005)
reclassification was finally published, close to its original
form. This work has created immense challenges for us.
In a single sweep, Števi established 97 suprageneric
taxa (tribes, subfamilies and families), four valid new
genera and 17 invalid new genera – and these numbers do
not include the many new superfamilies he recognised. It
is true that Dana (1851a–f, 1852a, b) and Alcock (1895,
1896, 1898, 1899, 1900a, b, 1901, 1910) both established
many new suprageneric taxa, but that was in a different,
simpler age. Even so both Dana and Alcock usually
discussed their decisions, and provided many excellent
figures. While the taxon diagnoses given in Števi
(2005) are typically detailed, it is nowhere made clear
how character information was derived – from original
examination of material, or simply from published
sources. Nor is there any indication of material examined.
Furthermore, his suprageneric taxa are not accompanied
by any specific discussion, justification, explanation,
Števi’s alternative liberal approach to taxa creation has
consequences. Unlike other biological disciplines where
information can be out-of-date and superfluous within 12
months, or a paper can be simply dismissed, taxonomists
must take into account any publication that proposes a
new name, from Linnaeus to the present (at least within
the relatively liberal guidelines of the ICZN Code). In
systematics all names correctly proposed are “available”,
whether they be considered valid, or a synonym of
another. In systematics, names have a legacy that goes
well beyond the quality of the original work. It is this
concern that underpins our reluctance to create new names
for groups that we have not sufficiently studied and
compared with others. Števi (2005) may well have
opened a “Pandora’s Box”. With an increasing number of
workers using cladistic and molecular tools to attempt to
understand brachyuran phylogeny, more and more
phylogenetic trees will be generated, and more
“theoretical” systematic groupings identified. If they
follow the example of Števi, it will be very tempting to
apply names to all the various clades and nodes they
generate, regardless of cross-validation from other lines of
investigation. Even when such suprageneric groupings are
later shown to be wrong, the names remain, and will make
our nomenclature all the more cumbersome.
One strength of Števi’s (2005) work is that it includes
fossils, and thus should be very useful to palaeontologists.
However, comparisons of fossil and extant crab material is
not always easy, and can be fraught with misinterpretation.
This is especially so where recent fossils are concerned,
since some may still be extant. Nevertheless, it is also
useful for workers on living crabs to have an overview of
the fossil fauna, and in this Števi (2005) should play a
useful role.

and commented that the current classification of the
Dromiidae did not reflect the wide variation of
morphological patterns it contained. They divided the
Dromiidae into three subfamilies: Dromiinae De Haan,
1833; Hypoconchinae Guinot & Tavares, 2003; and
Sphaerodromiinae Guinot & Tavares, 2003. Several
dromiine genera, however, were markedly restricted with
only the type species remaining, and consequently a
number of new genera were established. The new
diagnoses took into account not only classical characters
(as used by McLay, 1993), but also new ventral
structures, such as the thoracic sternum (rarely before
used in the dromiid systematics), the shape of sternal
sutures 7/8, the structure of the spermathecal openings at
their extremities, the uropods, and the male abdominal
formula (presence or absence of vestigial male pleopods
on abdominal somites 3–5 in combination with uropods,
the latter showing either as dorsal plates or as ventral
lobes). All characters both old and new are in
concordance. The presence or absence of a differentiated
mobile penial tube on the male P5 coxa (with consequent
modification to the coxa) was also studied, although not
all species could be examined and thus some generic
assignments must be regarded as tentative (hence the
“?”). Guinot & Quenette (2005) remarked that the
morphology of the spermatheca in the Dromiacea
(Homolodromioidea and Dromioidea) follows a similar
basic pattern with family subfamily variation. A long
spermathecal tube is a synapomorphy of the Dromiinae;
a short tube is present in the Hypoconchinae and
Homolodromiidae; while it is practically absent in the
Sphaerodromiinae and the Dynomenidae. This suggests
that the Sphaerodromiinae are basal or sister to the
Hypoconchinae + Dromiinae, and that the Dynomenidae
are sister to the remaining dromiacean families. In a
recent catalogue, Cleva et al. (2007) have reappraised the
generic position of some species. In a separate study in
progress by D. Guinot, Dromia foresti will be transferred
to Stimdromia (see also Cleva et al., 2007: 241).

Notes
{4} The type species of Dromia Weber, 1795, was
designated by the ICZN as Cancer personatus Linnaeus,
1758, as interpreted by the neotype (Opinion 688) (see
also Holthuis, 1962a, c). However, the poorly known
paper by Latreille (1810: 422) had, in fact, already
selected Dromia rumphii Weber, 1795, as the type species.
As the Commission has made a ruling on this, any earlier
type designation is invalid. It is, however, useful to note
that “Dromia Rumphii” was listed by Weber (1795) as a
synonym of “Cancer Dromia” [erroneus spelling for
Dormia] of Fabricius, so that Cancer dromia became the
type species by tautonymy. Dromia rumphii Weber, 1795,
is thus an objective synonym of D. dromia (Linnaeus,
1763). In any case, Dromia rumphii Weber, 1795, is a
nomen nudum as it was not accompanied by any
description or indication.
{1} To resolve the homonymy of the crab family
Dromiidae De Haan, 1833, with a beetle family,
Dromiidae Bonelli, 1810, an application was submitted by
Deuve et al. (2004) and subsequently approved by the
ICZN (Opinion 2149).
{2} The identity of Dromia nodipes Lamarck, 1818 (nomen
nudum) is problematic. Lamarck (1818: 264) commented,
“… le D. nodipes du mus. parait être le D. aegagropila de
Fab.”. However, the D. aegagropila of Fabricius was very
briefly described and its identity is not known. According to
Zimsen (1964), there are no extant types of D. aegagropila
and a search of the extant collections of Fabricius in the
Copenhagen Museum by P. K. L. Ng revealed nothing.
Dromia aegagropila, was doubtfully placed in
Austrodromidia McLay, 1993, by McLay (2001: 826).
Further, it is a provisional synonym of Dromia australasiae
Weber, 1795 (nomen nudum) (see Guinot & Tavares, 2003).
{5} D. Guinot is currently revising the generic positions of
Dromia dormia and D. wilsoni. Both species had been
placed in Dromia sensu lato by McLay (1993). Recently,
McLay et al. (2001) cited larval and adult characters
suggesting that D. wilsoni is not a Dromia species.

{8} Pectinura stearnsi Ives, 1891, has been cited as a
synonym of Paradromia japonica (Henderson, 1888), but
the correct name should be Cryptodromia stearnsi.
Pectinura stearnsi Ives, 1891, is actually an ophiuroid
echinoderm. In the same paper, Ives (1891) described a
new species of crab from Japan which he named
Cryptodromia stearnsi — the identity of the two specific
names probably led to the confusion. There is no genus of
crab with the name Pectinura.

{10} The generic assignment of Pseudodromia cacuminis
Kensley, 1980, will need to be re-examined as we consider
it unlikely to be a Pseudodromia.
{11} The subfamilial position of Frodromia McLay, 1993,
remains uncertain. Guinot & Tavares (2003) suggested it
might be a sphaerodromiine, but this is unconfirmed.
Despite it also having many dromiine features, we
tentatively place it in the Sphaerodromiinae pending
further investigations. We do not feel there is sufficient
cause to recognise the tribe Frodromiini Števi, 2005, at
this time.

Notes
{1} A nomenclatural comment is needed with regard to
Dynomene. Desmarest (1823) initially used the an invalid
vernacular name “Dynomène” (Desmarest, 1823: 219), as
shown by the use of a grave accent. However, on page 422,

Ng et al.: Systema Brachyurorum Part I
in his complete list of genera of Crustacea, Desmarest (1823:
422) wrote “Dynomene, Latr., 249, note”, without a grave
accent, and in italics like all other scientific names in his list.
His vernacular names like Chevrolle, Ecrevisse, Crevette,
etc., all are writen in normal type. Dynomene Desmarest,
1823, is thus correct, but the citation must refer to page 422,
not the earlier 219. No species was originally mentioned, but
Henri Milne Edwards (1837: 180) listed a single species,
Dynomene hispida. As he was the first author after
Desmarest (1823) to explicitly include a species in the
genus, following Article 67.2.2 of the Code, H. Milne
Edwards (1837) thus designated the type species by
monotypy.
The authorship of Dynomene hispida, is usually credited
to Guérin (1832) but this is incorrect. Guérin-Méneville’s
“Iconographie” was published over a period of 15 years
(1829–1844), and the date for the Crustacea volume is
1844, with 48 pages and 35 plates (see Cowan, 1971). As
such, Guérin-Méneville’s use of the name “Dynomene
hispida” was actually in 1844. However, the first author to
describe this species was actually Latreille, in Milbert
(1812) (see Notes in INTRODUCTION; Cleva et al.,
2007), who named it Cancer hispida. Latreille’s (1812:
274) short description leaves no doubt that his Cancer
hispida is the Dynomene hispida of other authors (not to
be confused with Domecia hispida Eydoux & Souleyet,
1842, presently in Domeciidae).

Notes
{1} Cancer cubicus Forskål, 1775, and Cancer
novemdecos Sulzer, 1776, are two names that have been
ignored. On the basis of their descriptions, we have little
doubt that both are synonymous with what is presently
known as Homola barbata (Fabricius, 1793). We thus
invoke Article 23.9.2 of the Code to conserve the junior
but more widely used name.

Notes
{1} Ranina Lamarck, 1801, was established for two species,
Cancer raninus Linnaeus, 1758, and Ranina serrata
Lamarck, 1801 (Lamarck, 1801: 156). Lamarck (1801)
incorrectly attributed Cancer raninus to Fabricius. Latreille
(1810: 422) identified the type species as Cancer raninus.
Fig. 16. Symethis corallica, Philippines (photo: P. Ng)
{2} Desjardins (1835: 10–12) described Ranina cristata
with the note: “Ranine corne de daim”, from Mauritius.
The species is apparently close to R. ranina but may be
distinct. Its status is uncertain.
{3} Raninoides fossor A. Milne-Edwards & Bouvier,
1923, is a junior subjective synonym of Notosceles
chimmonis Bourne, 1922 (see Cleva et al., 2007).
{4} According to Goeke (1984), Raninoides schmitti
Sawaya, 1944, is a junior synonym of Raninoides laevis
(Latreille, 1825). We agree, the description and figures by
Sawaya (1944) leave no doubt on this matter.
{5} Henderson (1888), in describing this species, attributed
it to a White MS name. White, however, never used name in
any of his publications (see Clark & Presswell, 2001).
{6} Goeke (1981) established a new subfamily, Symethinae,
for the genus. Guinot (1993) conditionally recognised it as a
distinct family in her review of the Raninidae (see also

Remarks. – Guinot (1966, 1967b) first suggested a
relationship between Hepatus and Aethra. While at first,
grouping such different genera may appear radical, the
differences blur when intermediate genera are considered.
Genera like Hepatella, Osachila and Sakaila show
intermediate forms, in a number of characters, between
Hepatus and Aethra, and in particular show the transition
from the sharply triangular mouthparts (third maxillipeds)
of Hepatus to the more quadrate form of Aethra.
Actaeomorpha, long associated with the Leucosiidae, is
also an aethrid — simply an apomorphic Osachila or
Sakaila. The same is true for Drachiella.

{1} The complex history and confusion over the spelling,
and authors, of the names Aethra Latreille in Cuvier, 1816,
and Oethra Latreille in Cuvier, 1816, have been discussed
in detail by Ng (1999a).
{2} Latreille, in Milbert (1812: 276) described Calappa
depressa with the following comments: “Le calappe
déprimé (calappa depressa) a la figure d'un ovale
transversal et échancré postérieurement. Sa surface est très
44
THE RAFFLES BULLETIN OF ZOOLOGY 2008
inégale; les pattes sont trés dentées. Cette espèce est une
des plus rares et des plus singulières.” His description of a
very rough carapace surface and dentate legs argues
against the taxon as being a species of Calappa as defined
today. In fact, it agrees well with what is currently called
Aethra scruposa (Linnaeus, 1764). Unfortunately,
Calappa depressa Latreille, in Milbert, 1812, is a senior
primary homonym of a widely distributed calappid crab,
Calappa depressa Miers, 1886 (see revision by Galil,
1997). Article 57.2 of the Code states that in the case of
primary homonyms, the junior name is permanently
invalid except when the conditions of Article 23.9.1 are
met, i.e. when the senior homonym has not been used as a
valid name since 1899 (Article 23.9.1.1); and the junior
homonym has been used for a particular taxon as its
presumed valid name in at least 25 works, published by at
least 10 authors in the immediately preceding 50 years and
encompassing a span of not less than 10 years (Article
23.9.1.2). Article 23.9.1.1 is easily fulfilled as Latreille’s
name has been forgotten or not used as a valid name since
1899. However, Article 23.9.1.2 cannot be fulfilled
because Calappa depressa Miers, 1886, although widely
distributed, is not often reported; we could only obtain
nine references (Tyndale-Biscoe & George, 1962; Guinot,
1967d; Serène, 1968; Galil, 1997; Davie, 2002; Ng,
2003a; Poore, 2004; Lai & Ng, 2006; Richer de Forges &
Ng, 2006). As such, Article 57.2 prevails for the
homonymy of these two names. The name Calappa
depressa Miers, 1886, must thus be replaced by its next
available synonym, C. woodmasoni Alcock, 1896.

{3} The Copenhagen Museum has a specimen labelled as
a possible type of "Calappa angustata Fabricius" (male,
55.8 by 40.7 mm, ZMUC Cru 126). The specimen was in
a box with a specimen of C. gallioides Stimpson, and both
supposedly from Ghana. The original description and
colour notes of Fabricius (1798) do not match any known
Atlantic Calappa species, but seem closer to Hepatus. The
putative type specimen also does not agree with Fabricius’
description, and thus we do not regard it as a type, the
tentative label being almost certainly wrong.

Remarks. – The relatively elongated species of Bellia and
Corystoides superficially resemble corystids and some of
the atelecyclids, and all burrow. However we can assume
the similarities are due to convergence as these belliids
have no antennular fossae, and male abdominal segments
3–5 are fused (vs. free). They also have a proportionately
longer G2 compared to corystids. Acanthocyclus is related
to Bellia and Corystoides, because it also lacks antennular
fossae, although the antennules are much shorter and less
setose than those of Bellia and Corystoides.
Notes
{1} The precise authorship for these taxa should be
“Lucas, in H. Milne Edwards & Lucas, 1844”, not “H.
Milne Edwards & Lucas, 1844” as more frequently cited
(Guinot & Cleva, 2002). Also, the reference, H. Milne
Edwards & Lucas (1842–1844), is problematic in that the
publication came out in a series of undated parts, and the
precise date of publication of each is uncertain. Following
the Code, the latest date should be followed for all new
taxa described inside this publication, i.e. 1844.
Heterozius does not fit into the typical "belliid plan"
(Guinot, 1976). Its antennules fold normally into well
formed fossae, the G1 is straight, not curved, and
proportionately more slender; and the G2 is much shorter,
being only about 1/4 the length of the G1. The carapace of
Heterozius is also clearly tranverse, more closely
resembling pseudoziids like Pseudozius. The G1 and G2
of Heterozius ,bear a resemblance to those of Pseudozius.
However, Heterozius has male abdominal segments 3–5
fused as in other belliids (versus all segments free in
Pseudozius). Lacking further evidence, we are inclined to
consider Heterozius to be a plesiomorphic belliid, but
requiring its own subfamily, Heteroziinae Števi, 2005.

Notes
{1} The confusing state of affairs associated with this
name have been discussed by Holthuis (2001).
{2} Remarkably, the name Cancer tuberculatus Fabricius,
1793, has been ignored since it was published. Fabricius
(1793: 454) described it from “Habitat in Oceano pacifico
Mus. Dom. Banks”. This locality is too vague to be
reliable, but it is likely to be from somewhere in Australia,
from which many of his specimens came. Fabricius (1798:
345) subsequently referred it to Calappa. In the ZMUC is
a specimen labelled as the type (Cru 61, female, 70.1 ×
52.5 mm) that agrees well with his description. It is here
designated the lectotype of Cancer tuberculatus Fabricius,
1793. This specimen is identical to what Galil (1997: 304)
recently described as Calappa matsuzawa, and we here
synonymise the two names. While C. matsuzawa has thus
far only been reported from Japan (type locality) and
Philippines (Ng, 2002b), its possible presence in Australia
can be expected if our interpretation of the type locality is
correct.

Remarks. – The affinities of the Matutidae with the
Calappidae are not clear and they are probably not closely
related. Števi (1983) questioned the classical
composition of the Calappidae as being one family with
two subfamilies, Calappinae and Matutinae, and since
then, an increasing number of workers have chosen to
recognise the two taxa as distinct families (e.g. Bellwood,
1996; Ng, 1998; Ng et al., 2001; Davie, 2002). Bellwood
(1996) reappraised the affinities of the Matutidae and
suggests it is not close to the Calappidae. Certainly, the
form of their ambulatory legs and chelipeds are very
different. Until more work is done, we take the somewhat
more conservative approach and keep the Matutidae and
Calappidae in one superfamily, Calappoidea.

SUPERFAMILY CANCROIDEA
LATREILLE, 1802
Remarks. – The composition of the superfamily
Cancroidea has varied with different authors. The
Portunoidea are sometimes included, and while there does
appears to be a link, we prefer to keep them apart until
more compelling evidence surfaces. Recently, the
Atelecyclidae sensu stricto has also been assigned to the
Cancroidea (Guinot et al., 2008), however the composition
of this family is also currently bring re-evaluated and it is
to be restricted to the type-genus Atelecyclus Leach, 1814.
All other atelecyclid genera are not in the Cancroidea, and
are being referred elsewhere. Peltarion Hombron &
Jacquinot, 1846, Podocatactes Ortmann, 1893,
Pteropeltarion Dell, 1972, and Trichopeltarion A. MilneEdwards, 1880 (= Krunopeltarion Števi, 1993), will be
placed into a separate new family (see Cleva & Tavares, in
prep.; Guinot et al., 2008). The status of the unusual genus
Pseudocorystes H. Milne Edwards, 1837, is also uncertain.
Because all the relevant research data sets are not yet
published, we keep all these genera in the Atelecyclidae
and the Cancroidea (both sensu lato) for convenience and
ease of reference.

= Podocatactes Ortmann, 1893 (type species Podocatactes

Podocatactes hamifer Ortmann, 1893
Podocatactes has been long placed in the Corystidae, but
other than its elongate carapace and somewhat setose
antennae, it has nothing in common with typical corystids.
Specifically: all male abdominal segments are free; the G1
is stout; the G2 is longer than the G1; the antennae are
much shorter than a typical corystid (distinctly less than
half carapace length), and the setae are less dense and
shorter; and finally, male Podocatactes have pronounced
heterochely and an asymmetrical sternum. It is thus
necessary to transfer Podocatactes to the group including
Peltarion, Pteropeltarion and Trichopeltarion (currently
in the Atelecyclidae, but as mentioned above, to be in a
new family) (see also Ng et al., 2001). As mentioned for
Podocatactes, some of these genera (e.g. Trichopeltarion
and Peltarion) have a markedly asymmetrical thoracic
sternum, being wider at the base of the very enlarged
cheliped (see Guinot & Bouchard, 1998: Fig. 13D).
Presumably this cheliped requires an enlarged block of
muscle to support and move it, causing the asymmetry.
We have observed this phenomenon only in crabs with a
narrow sternum. Crabs with a broad sternum must have
sufficient space inside the sternites for the enlarged
muscles — certainly sternal asymmetry is not known in
gecarcinids or Uca.

Notes
{1} The nomenclatural complexities associated with the
suprageneric names Chlorodinae Dana, 1851, and
Atelecyclidae Ortmann, 1893, as well as the generic
names Atelecyclus Leach, 1814, Clorodius Desmarest,
1823, Chlorodius H. Milne Edwards, 1834, and
Chlorodius Agassiz, 1846, have been discussed in depth
by Ng & Holthuis (2007). The genus Chlorodius H. Milne
Edwards, 1834, and subfamily Chlorodinae Dana, 1851,
have long been associated with the Xanthidae sensu
stricto, but the original descriptions make the matter
complex.

{2} Salva & Feldmann (2001), in a re-apprasial of the
Atelecyclidae using extant and fossil taxa, synonymised
Trichopeltarion and Trachycarcinus Faxon, 1893. While
we agree in principle, we are not yet convinced that
Trichopeltarion is monophyletic. Salva & Feldmann
(2001) specifically excluded three species from
Trichopeltarion, viz. Trachycarcinus delli Guinot, 1989,
T. foresti Guinot, 1989, and T. hystricosus Garth, in Garth
& Haig, 1971, with the suggestion that they may need to
be referred to another, perhaps new genus. We tentatively
continue to include them in Trichopeltarion. A revision of
the Atelecyclidae is ongoing by Régis Cleva and Marcos
Tavares. Salva & Feldmann’s (2001) revision missed
several recent papers, most notable being the formal
removal of Kraussia out of this family and into a separate
subfamily in the Xanthidae (Ng, 1993; see also Clark &
Ng, 1997). The diagnosis of the Atelecyclidae (restricted
to Atelecyclus, type and sole genus) must be emended, and
the family transferred to the Cancroidea (Guinot et al.,
2008).

{3} Števi (1993) established a new genus,
Krunopeltarion, for a new species, Krunopeltarion
timorense Števi, 1993, from the Timor Sea. Recent work
suggests that the genus is a junior subjective synonym of
Trichopeltarion A. Milne-Edwards, 1880 (D. Guinot,
unpublished data; see also Cleva & Tavares, in prep.).

two species in Carpilius, Cancer corallinus and Cancer
maculatus. However, he did not indicate either as type
species. Rathbun (1930: 239) stated that the type was
Cancer maculatus Linnaeus, 1758, and most people
follow this. The ICZN made a ruling on this in Opinion
73, regarding Cancer maculatus as the type species by
monotypy, and effectively ratified Rathbun’s (1930)
selection. However, E. Desmarest (1858: 17) [not to be
confused with A. G. Desmarest, see Introduction] had
much earlier stated that the type species is Cancer
corallinus, and although this has clear priority over
Rathbun’s (1930) action, Opinion 73 has precedence over
this, and Cancer maculatus remains as the type species of
Carpilius. Clark et al. (2005), however, have suggested
that the three species now placed in Carpilius may not be
congeneric. This matter is now under review by P. K. L.
Ng, D. Guinot and P. F. Clark.
SUPERFAMILY CARPILIOIDEA
ORTMANN, 1893
Remarks. – The Carpiliidae has a suite of unusual adult
and larval characters (see Guinot, 1968c; Clark et al.,
2005) that suggest that its traditional inclusion in the
Xanthoidea is unwarranted. Karasawa & Schweitzer
(2006) were the first to recognise this as a superfamily.
Števi (2005) recognised it as a family in the Eriphioidea.
FAMILY CARPILIIDAE ORTMANN, 1893
Carpilidés A. Milne-Edwards, 1862 (not in Latin, unavailable
name)
Carpiliinae Ortmann, 1893
Remarks. – Three genera have been at one time or another
referred (some tentatively) to the Carpiliidae, but our
studies indicate that only Carpilius belongs there (see also
Guinot, 1968c). The male abdomen of Carpilius has been
variously stated as segments 3–5 or 4–6 fused, but only
segments 3 and 4 can be truly regarded as fused. Between
these two segments, the suture is very shallow or
indiscernible. Segment 5 retains some motion from
segments 3/4, and though the movement is much less than
that of the other free segments, it cannot be regarded as
fused. The larvae of true carpiliids are very distinctive (see
Laughlin et al., 1983; Clark et al., 2005). The two other
genera sometimes placed in the Carpiliidae are Liagore,
here referred to the Xanthinae, Xanthidae (see Ng & Chen,
2004a); and Euryozius, here transferred to the
Pseudoziidae (see Ng & Liao, 2002) (see discussion for
these families).
{2} Cancer adspersus Herbst, 1790, Cancer petraea
Herbst, 1801, and Cancer marmarinus Herbst, 1804, have
not been used since their description, and the latter two
were not treated by Sakai (1999). On the basis of the
descriptions and figures, we consider C. adspersus (see
Herbst, 1790: 264, pl. 21 fig. 119) and C. petraeus (see
Herbst, 1801: 18, pl. 51 fig. 4) to be identical with
Carpilius convexus, the different colour patterns being
explained by the variable nature of this character.
Similarly, Cancer marmarinus (see Herbst, 1804: 7, pl. 60
fig. 1) matches C. corallinus.

Notes
{1} Desmarest (1823: 227) listed Cancer corallinus
(which he incorrectly attributed to Fabricius) in his
compilation, and in a footnote for the species on the next
page (p. 228), he noted that Leach had proposed to him
that he would establish a new genus, Carpilius, for Cancer
maculatus (also incorrectly attributed to Fabricius), and
that it would be diagnosed by various carapace features.
The diagnosis, while very short, is nevertheless sufficient,
and makes the name available from Desmarest (1823), and
the authorship of the genus should be credited to him even
though the concept may have been Leach’s (see
Introduction). The type species is not so obvious. From
Desmarest’s (1823) account, it is clear that he recognises

THE RAFFLES BULLETIN OF ZOOLOGY 2008
Dairidae and Dacryopilumnidae.
SUPERFAMILY DAIROIDEA SERÈNE, 1965
Remarks. – The systematic status of Daira and Dairoides
has long been a challenge. Believed to be related, they
have often been classified together. Guinot (1967b)
discussed the possible affinities of the two genera but left
the matter unresolved. Daira, while superficially looking
like many xanthids, has many unusual features, and in
particular, a unique cuticular ornamentation Guinot
(1967b, 1977a). Dairoides has similarities with Daira,
although externally, it more closely resembles a parthenopid. For this reason, most modern texts keep Daira in
the Xanthidae (see Sakai, 1976; Dai & Yang, 1991) and
Dairoides in the Parthenopidae (see Sakai, 1976; Ng & S.
H. Tan, 1996; Ng et al., 2001). Serène (1965a: 37)
established Dairoida in Xanthidae for Daira, Dairoides
and Dacryopilumnus, without comment or diagnosis, and
while this grouping is interesting, most have focussed on
just Daira and Dairoides. This was partly because Serène
(1984) later established a new subfamily in the Eriphiidae
(as Menippidae) for Dacryopilumnus, which was widely
accepted as a member of the Xanthoidea. Ng & Rodríguez
(1986) defined Dairidae for Daira and Dairoides when
they reviewed the state of parthenopid systematics, and
were the first to use it as a family. Števi (2005) also
focussing on Daira and Dairoides, established a new
family, Dairoididae, for the latter, and placed both in the
superfamily Dairoidea.
Dairoides is most closely allied to the eriphioids. All
eriphioids and Dairoides share the same suite of key
characters: chelae are markedly heterochelous, but both
relatively short, the larger chela with a crushing or peeling
tooth at the base of the dactylus, and the smaller chela
with slender forceps-like fingers of varying lengths; the
press-button on the sterno-abdominal cavity that retains
the abdomen, consists of a rounded tubercle positioned on
the posterior edge of sternite 5; and the male abdomen is
usually relatively broad. In most parthenopids, the chelae
are usually very long, usually heterochelous, with the
larger chela possessing a prominent crushing (never
peeling) tooth at the base of the dactylus, and the smaller
chela with short, stout fingers; the press-button tubercle on
the sterno-abdominal cavity consists of a low peg-like
tubercle on the anterior edge of sternite 5; and the male
abdomen is slender. While the chelae of parthenopids and
eriphioids (and Dairoides) are all heterochelous, they look
very different in form, with those of eriphioids especially
distinctive. The large chela of some eriphiiods is specially
adapted for peeling gastropods (like in calappids, see Ng
& L. W. H. Tan, 1984a, 1985), with the smaller chela
acting like a pair of forceps to extract the flesh of the
broken mollusc. They can do this to varying degrees, with
some species of Ozius even changing from peeling to
crushing as they grow in size (P. K. L. Ng, unpublished
data), and all clearly use their chelae differently – one for
crushing or peeling the molluscs, and the other to pull out
the meat within. It seems this feeding method is common
to all eriphioids and Dairoides. The peculiar carapace and
other features of Dairoides are clearly highly apomorphic,
but the fact that it has the same kind of chelipeds, broad
abdomen and press-button, makes for a convincing case
that it is close to eriphioids and should be placed there.
However, as suggested by Števi (2005), it should be
placed in its own family, the Dairoididae.
With S. H. Tan, we had a detailed look at the
representative genera of the Eriphiidae, Menippidae and
Oziidae (eriphioids as defined within this work, the
Eriphiidae of Ng, 1998), and selected members of the
Parthenopidae, as well as Daira, Dairoides and
Dacryopilumnus. Members of all these taxa have a very
stout G1 and a long G2 which is as long as, or much
longer than the first, so this character is not informative.
Against expectations, we found that Daira and
Dacryopilumnus are allies, as Serène (1965a) first
suspected. In both genera the chelae are similar in form or
only slightly heterochelous, neither chela having any
cutting teeth, the fingers of both chelae are short, closing
completely without any gape, and the distal part is
partially scalloped with the margins denticulate; the pressbutton on the sterno-abdominal cavity that retains the
abdomen, consists of a low peg-like tubercle positioned on
the anterior edge of sternite 5; and the male abdomen is
narrow. While the press-buttom structure and male
abdomens of parthenopids, Daira and Dacryopilumnus are
similar, and suggest a relationship between them, they
differ markedly in carapace and other features. In
particular their chelipeds are very different. The evidence
therefore indicates the parthenopids should be in their own
superfamily (Parthenopoidea), separate from Daira and
Dacryopilumnus, which we here transfer to the Dairoidea
as redefined here. As Daira and Dacryopilumnus have
several other marked differences in the form of the
carapace, endostome and legs, it seems reasonable to keep
them in separate families for the time being, i.e. the
The relationships within and between the superfamilies
Eriphioidea, Dairoidea and Parthenopoidea are complex,
and we hope ongoing research, in particular using larval
and molecular tools, will help shed more light on this
problem.

authors (e.g. Ng, 1998) have considered the name to be a
nomen nudum. However Article 11.7.1 of the Code allows
the name to be regarded as available as long as there is a
mention or indication of the type genus. Thus Dairoida
Serène, 1965, is an available name. Števi (2005) was
therefore correct in giving authorship of the family to
Serène (1965a).

of the Dorippidae sensu stricto have the male gonopores

Fabricius, 1798. At the time of Weber (1795), Dorippe
astuta Fabricius, 1798, and Dorippe callida Fabricius,
1798, were both nomina nuda, and Cancer lanatus
Linnaeus, 1767, was only questionably assigned to
Dorippe. As such, there was only one valid species
included in the original description of Dorippe Weber,
1795, Cancer quadridens Fabricius, 1793, and it must be
the type species by monotypy. Dorippe astuta Fabricius,
1798, is actually a junior synonym of Dorippoides
facchino (Herbst, 1785). The identity of D. callida and its
designation as the type species of Neodorippe Serène &
Romimohtarto, 1969, has been confirmed by the

Fabricius (1798), that was described from the unpublished
notes of Daldorff (see discussion of Weber versus
Fabricius in the main Introduction). One also questions if
he may not have been confused with Cancer pinnotheres
Linnaeus, 1758 (now in Nepinnotheres Manning, 1993,
Pinnotheridae).

{1} Castro (2005: 559) argued that Ethusina insolita Ng &
Ho, 2003, is a junior synonym of E. dilobotus Chen, 1993,
but noted there were some differences even though the
gonopod structures were similar. Specimens of the two
species, both from Taiwan (see Ng & Ho, 2003) suggest
there are two separate taxa, and we maintain them as
separate taxa at least until more material becomes
available. Similarly, Castro (2005: 570) synonymised
Ethusina robusta (Miers, 1886) with E. investigatoris
Alcock, 1896, and E. alcocki Ng & Ho, 2003, however the
range of character variation suggests at least two taxa.
This matter will need more detailed study, but for the
moment, we retain the synonymy with some hesitation.

Ng et al.: Systema Brachyurorum Part I
SUPERFAMILY ERIPHIOIDEA
MACLEAY, 1838
posterolateral margins sharply converging towards the
posterior carapace margin.
Remarks. – Števi (2005) was the first to recognise the
superfamily Eriphioidea with four families, Eriphiidae,
Ladomedaeidae, Pilumnoididae and Carpiliidae. Karasawa
& Schweitzer (2006) had a different arrangement,
recognising in it, the families Eriphiidae, Oziidae,
Hypothalassiidae, Platyxanthidae and Pseudoziidae.
The Oziinae have either an open or almost closed orbital
margin; the antenna is positioned near the orbit and
antennule; the larger chela has a prominent tooth
(molariform to peg-like) for crushing or peeling molluscs;
the anterior thoracic sternum is tranversely broad without
a longitudinal groove on sternite 4; the male abdomen is
relatively narrower with the lateral margins weakly
converging towards the telson; the distal part of the G2
tapers gradually to a sharp tip, with the distal part
subequal or longer than the subdistal part. Carapaces are
generally transversely ovate.
As was discussed earlier under the Dairoidea and
Dairidae, the Eriphioidea recognised here is a coherent
group defined by the following characters: the chelae
are markedly heterochelous and relatively short, the
larger chela has a crushing or peeling tooth at the base
of the dactylus, and the smaller chela has slender fingers
of varying lengths but never with a crushing tooth; the
press-button on the sterno-abdominal cavity that retains
the abdomen is a rounded tubercle positioned on the
posterior edge of sternite 5; and the male abdomen is
relatively broad to very broad. On the basis of these
characters, we exclude the Pseudoziidae and
Pilumnoididae (referred to Pseudozioidea), as well as
Carpiliidae (to Carpilioidea). The Ladomedaeidae is a
synonym of the Euxanthinae (Xanthidae) as it was
diagnosed incorrectly (see Manuel-Santos & Ng, 2007).
The present classification also makes changes to the
families recognised by Števi (2005) and Karasawa &
Schweitzer (2006) which we now include in this
superfamily.
The Menippinae have an open orbital margin; the antenna is
positioned near the orbit and antennules; the larger chela has
a prominent molariform tooth for crushing molluscs (not
peeling tooth); the anterior thoracic sternum is longitudinally
broad with a prominent longitudinal groove on sternite 4; the
male abdomen is relatively broad with the lateral margins
more or less subparallel; and the distal part of the G2 tapers
abruptly just before the end, with the terminal part filiform in
structure. Carapaces are generally transversely ovate.
The Dacryopiluminae are very unusual as they have their
eyes positioned at the lateral edge of a trapezoidal
carapace, with the frontal and anterolateral margins entire;
the orbital margin is not closed; the antenna is positioned
some distance from the orbit and frontal margin; the
chelipeds are subequal, both lack a crushing or peeling
tooth, and they are scalloped distally; the anterior thoracic
sternum is broad without a prominent longitudinal groove
on sternite 4; the male abdomen is narrow with the lateral
margins weakly converging towards the telson; the distal
part of the G2 tapers abruptly just before the end, with the
terminal part filiform. Carapaces are prominently
trapezoidal with the posterolateral margins sharply
converging.
Crosnier (in Serène 1984) recognised three subfamilies in
what he called the Menippidae: Eriphiinae, Oziinae
(regarded as a senior synonym of Menippidae) and
Dacryopiluminae. As discussed earlier (see also Koh &
Ng, 2007), if Menippidae Ortmann, 1893, Eriphiidae
MacLeay, 1838, and Oziidae Dana, 1851, are regarded as
synonymous or in the same family, the oldest name that
must be used is Eriphiidae. Based on an unpublished
thesis by S. K. Koh, Ng et al. (2001) discussed in depth
the problem of groupings in the Eriphiidae (= present
Eriphioidea) and argued that four distinct groups (i.e.
subfamilies) can be recognised – Eriphiinae, Menippinae,
Oziinae and Dacryopilumninae, and this was followed by
Davie (2002). As earlier discussed however, in the present
work we transfer the Dacryopilumninae to form its own
family within the Dairoidea. As the work in Ng et al.
(2001) was brief, we elaborate on it here and discuss new
characters recently discovered.
Looking at these groups, it seems reasonable to recognise
the first subfamilies as full families within the Eriphioidea,
i.e. the Eriphiidae, Menippidae, Oziidae. However, as
discussed earlier under the Dairoidea and Dairidae, the
relationships of the Dacryopilumnidae lie with the
Dairoidea. Karasawa & Schweitzer (2006) argued that
Hypothalassia (placed in the family Menippidae (as
Menippinae) by Ng et al. (2001) and Davie (2002), should
be transferred to a new family, the Hypothalassiidae. We
have re-examined specimens of the two species in the
genus (see Koh & Ng, 2000), and the anterior thoracic
sternal structure is rather different from other members of
the Menippidae as now defined. It has sufficient “atypical”
features to perhaps justify recognizing this family for the
moment. In any case, its affinities still appear to be with
menippids.
The Eriphiinae have a totally closed orbital margin; the
antenna is positioned some distance from the orbit and
antennule, being inserted almost vertically at the outer
edge of the frontal margin; the larger chela has a
prominent molariform tooth for crushing molluscs (not a
peeling tooth); the anterior thoracic sternum is
longitudinally broad with a prominent longitudinal
groove on sternite 4; the male abdomen is relatively
broad with the lateral margins more or less subparallel;
and the distal part of G2 tapers gradually to a sharp tip,
the distal part is long but distinctly shorter than the
subdistal part. Carapaces are trapezoidal, with the
As has been discussed earlier for Daira and Dairidae, we
believe Dairoides is a member of the Eriphioidea, the
peculiar carapace and legs being the result of extreme
apomorphy. In the form of its abdomen, sternum and
chelipeds, we have little doubt it is an eriphioid.

The family Platyxanthidae Guinot, 1977, is also transferred to the Eriphioidea. The family has been linked with the
Xanthidae and Guinot (1979) treated it provisionally as a
subfamily in the Xanthidae. However, its sternal, male
abdominal as well as gonopodal characters all demonstrate
affinities with the eriphioids (see Guinot, 1968: 695–699,
Figs. 1–12; Guinot, 1979: 94, Fig. 25). In platyxanthids,
the thoracic sternum is relatively narrow, male abdomen
relatively broad with all segments freely articulating (like
most menippids), G1 relatively stout, simple and armed
only with short spines and setae, and the G2 usually as
long as or longer than the G1 (except for Peloeus which
has a relatively shorter G2, see Guinot, 1968a: Fig. 12).

{1} The first designation of a type species for Eriphia
should be by H. Milne Edwards (1842). In his plates from
Cuvier’s “Règne Animal”, which he also notes represent
types, Eriphia spinifrons is figured (in colour) on plate 14.
According to Cowan (1976), plate 14 was published in
November 1842.
{2) Eriphia smithii is supposedly a widely distributed
Indo-West Pacific species. The actual E. smithii is
restricted to the Indian Ocean. Most of the specimens in
Southeast and East Asia as well as Australia belong to an
undescribed species (Koh & Ng, in press).
Notes
{1} The affinities of the Superfamily Dairoidea and the
status of the family Dairoididae has been discussed earlier.
A point of nomenclature is important. Števi (2005)
wrote the family name as “Dairoididae Števi, in Martin
& Davis, 2001”. We find no indication of this name in
Martin & Davis (2001), and the first valid publication of
Dairoididae is by Števi (2005).

Notes
{1} In establishing Pseudocarcinus, H. Milne Edwards
(1834: 407–409) listed four species as belonging to his
new genus, viz. Cancer rumphii Fabricius, 1798,
Pseudocarcinus bellangerii H. Milne Edwards, 1834,
Pseudocarcinus ocellatus H. Milne Edwards, 1834, and
Cancer gigas Lamarck, 1818. No type species was
designated. Most of the current literature accepts the type
designation by Miers (1886) who selected Cancer gigas
Lamarck, 1818, as the type species (see also Davie, 2002).
The Commission placed Cancer gigas Lamarck, 1818, on
the Official List and regards it as the type species of
Pseudocarcinus (Opinion 85, Direction 37) (ICZN, 1987).
E. Desmarest (1858: 17) commented that Cancer rumphii
Fabricius, 1798, was the type species, and his designation
is not only valid but precedes that of Miers (1886). As has
been discussed above, E. Desmarest is not to be confused
with the better known A. G. Desmarest, and his 1858
paper is poorly known. If E. Desmarest’s designation is
accepted, it would mean that Pseudocarcinus H. Milne
Edwards, 1834, becomes an objective junior synonym of
Menippe De Haan, 1833, whose type species is also
Cancer rumphii Fabricius, 1798 (subsequent designation
by Glaessner, 1929). Fortunately, because of ICZN
Opinion 85, any earlier type selection is invalid, and
Cancer gigas Lamarck, 1818, remains the type species of
Pseudocarcinus H. Milne Edwards, 1834. This is
significant as Pseudocarcinus gigas (Lamarck, 1818), well
known as the Tasmanian Giant Crab, Australian Giant
Crab or Queen Crab, is one of the largest crabs in the
world and has substantial commercial value (see Gardner,
1998; Ng, 1998; Davie, 2002).

always been uncertain. Examination of the syntypes in
ZMUC (1 male, 15.5 by 12.3 mm, Cru 112-4; 1 male, 18.0
× 14.0 mm, Cru 112-1; 1 female, 18.4 × 14.2 mm, Cru
112-2; 1 female, 18.4 × 14.2 mm, 112-3; 1 female, 17.7 ×
13.5 mm, Cru 112-5; “India Orientali”, Dom. Daldorff)
clearly identifies it as a species of Sphaerozius.
Sphaerozius, however, has only one recognised species,
Sphaerozius nitidus Stimpson, 1858, although there are a
number of junior subjective synonyms. One of the authors
(P. K. L. Ng) has examined a good series of specimens
from Singapore, Malaysia and southern China, and they
all agree with the definition of Sphaerozius nitidus, as
described by Stimpson (1858a, 1907) and all subsequent
authors. Cancer scaber is prominently granular, while S.
nitidus
is a smoother crab, thus two species of
Sphaerozius must be recognised. Sakai (1999: 31)
recognised Sphaerozius panope (Herbst, 1801) in his
reappraisal of Herbst’s taxa, and from his figure (K. Sakai,
1999: pl. 16C), it is clear that it is a synonym of
Sphaerozius scaber (Fabricius, 1798). Pilumnopeus
granulosus Miers, 1880, is also probably the same species.
A revision is clearly necessary to clarify the identities of
the other available names.

Eupilumnus with Pilumnus Leach, 1815; Rathbun's (1930)
action is valid and effectively makes Pilumnus

Globopilumnus Balss, 1933 (see Ng et al., 2001). Guinot

Milne Edwards, 1834, O. guttatus H. Milne Edwards,

species, either by monotypy (which is incorrect) or from

Remarks. – The classification of the Gecarcinucoidea has
come under some scrutiny recently. Bott (1970)
recognised three families in it, the Gecarcinucidae
Rathbun, 1904, Parathelphusidae Alcock, 1910, and
Sundathelphusidae Bott, 1969. Various authors hace
challenged the characters used to distinguish these
subfamilies. Holthuis (1979) queried the accuracy of the
frontal median triangle as a character, suggesting there
may be more variation than Bott (1970) accepted. More
studies (e.g. Ng, 1988, 1990b; Ng & Stuebing, 1989,
1990; Ng & Sket, 1996) have subsequently shown that this
character is not reliable; and these authors synoymised
Sundathelphusidae with the Parathelphusidae. Studies by
Ng (1988) and Ng (1990) also suggested that the
Gecarcinucidae may also not be distinct from the
Parathelphusidae, and the latter may be a synonym.
Recently, Bahir & Yeo (2007) cast more doubt when they
rearranged several genera between these two families.
Klaus et al. (2006), in a major rearrangement of
gecarcinucoid and potamoid families and subfamilies,
argued on the basis of DNA and gonopodal characters that
the Gecarcincoidea was composed of two sister groups,
the Deckeniidae (with three subfamilies, Deckeniinae,
Globonautinae
and
Hydrothelphusinae)
and
Gecarcinucidae (with two subfamilies, Gecarcinucinae and
Parathelphusinae). In a markedly different conclusion
drawn mainly from molecular evidence, Daniels et al.
(2006) argued that the deckenines, globonautines and
hydrothelphusines were potamonautids in the Potamoidea,
and allied to the Potamidae (see also Cumberlidge et al.,
2007; and our later remarks for Potamidae and
Potamonautidae). In a recent appraisal of the world
freshwater crab fauna, Yeo et al. (2008) followed
Cumberlidge et al. (2008) in treating all the African crabs
as belonging to the Potamoidea, and recognised two
families in the Gecarcinucoidea.

{1} Bahir & Yeo (2007) regarded Gubernatoriana Bott,
1970, and Travancoriana Bott, 1969, as belonging to the
Gecarcinucidae. They also partially revised these genera.
Three species placed by Bott (1970) in Gubernatoriana
were referred to two new genera; G. nilgiriensis (Roux,
1931) and G. pusilla (Roux, 1931) were transferred to
Vanni Bahir & Yeo, 2007; while G. escheri (Roux, 1931)
was moved to Snaha Bahir & Yeo, 2007. Travancoriana
malabarica (Henderson, 1912) was also transferred to
Vanni. A taxon missed by most workers, Paratelphusa
(Liotelphusa) malabarica var. travancorica, was regarded
as a valid species of Vanni. Travancoriana carli (Roux,
1931) was transferred to Vela Bahir & Yeo, 2007.
{2} One distinctive species, Barytelphusa lamellifrons
(Alcock, 1909), was referred to its own genus, Lamella
Bahir & Yeo, 2007. The genus, however, Barytelphusa, is
still in urgent need of a revision.

Notes
{1} Austrothelphusa species are endemic to Australia,
except for the poorly known A. insularis (Colosi, 1919)
supposedly from Fiji but not reported since. Two of the
authors (P. K. L. Ng and P. J. F. Davie) have discussed
this matter at some length with Satish Choy, who was born
and raised in Fiji, and he is very certain this record is
mistaken. The geographical location is also suspect – the
easternmost record for any freshwater crab is in the
Solomons, Sendleria salomonis (Roux, 1934) (see also
Bott, 1969, 1970). The identity of A. insularis (Colosi,
1919) remains unclear and the types need to be checked. A
revision of the Australian species of Austrothelphusa
under way by P. J. F. Davie also suggests the Australian
fauna is much more diverse than previously thought, with
potentially triple the number of species presently
recognised.

from Palawan in the Philippines. Subsequently, more
species have been reported from that island (Freitag &
Yeo, 2004). Two species were described from the small
island of Balabac north of Palawan – P. balabac Ng &
Takeda, 1993, and P. parma Ng & Takeda, 1993. Recent
collections from Balabac by H. Freitag show that the
differences between the two species can best explained by
variation and an anomalous growth on the G1 of the type
of P. balabac (unpublished data). The two species will be
synonymised in an upcoming paper where these aspects
are discussed in detail.

Fabricius, 1798, in the Copenhagen Museum. This is
clearly a species of Somanniathelphusa, but the type
specimens are in very poor condition, with the diagnostic
G1 structures only partially intact. While it bears some
resemblance to S. amoyensis, no reliable decision on its
identity has yet been made.
{5} The name Aberrothelphusa Ng, in Fransen, Holthuis
& Adema (1997) is an unfortunate lapsus. This was the
original name intended for the type species, Mainitia
nieuwenhuisi Bott, 1970, and the labels were captured by
the museum databases resulting in the name being
published in Fransen et al.’s (1997) catalogue. Although
the type species of Aberrothelphusa was indicated, since
this was a name published after 1930, the Code (Article

(2002), the first valid publication of a name for this genus
is therefore Torhusa Ng, 1997.
now under study by N. Cumberlidge and P. K. L. Ng. The
genus Terrathelphusa is currently represented by six
species (Ng, 1989, 1997).
{6} Weber’s (1795) list was compiled from various
sources, including his own, and included the unpublished
records of Daldorff as well as published accounts like
those of Fabricius. For Fabricius, Weber also listed taxa
that Fabricius had not yet published by 1795, but which he
later did in 1798. Weber indicated such records with an
“S”, i.e. the Supplementum of Fabricius (1798). Because
Weber did not always state whose names they were, and
whether any were new, a clear determination of authorship
can be confusing. Fortunately, authorship can often be
determined by cross-referring the names to the papers of
Linnaeus, Pallas, Pennant, Fabricius and Herbst. In this
manner, we have sorted out which of the names in Weber
were new, or can be regarded as such.
Fig. 56. Geithusa pulchra, Peninsular Malaysia (photo: P. Ng)
In Weber’s paper, the arrangement of the names within
each of the genera he recognised was clearly not
alphabetical, and from the names, it is obvious that he
grouped what he thought were related taxa together. For
Alpheus vitulus (a name he attributed to Daldorff), the
two names before it were Alpheus ruricola and A. senex,
and the two after it were A. maculatus and A. tridens (as
“3 dens”). Alpheus senex was attributed to Fabricius
(1798), and the types in the ZMUC show that this is what
is today known as Oziotelphusa senex (Fabricius, 1798),
a species of freshwater crab from southern India (see Ng
& Tay, 2001). The name “Alpheus tridens” was
attributed to Fabricius (1798) and while its identity is
uncertain (there are no type specimens of this in the
ZMUC), it seems most likely to be Parathelphusa
tridentata H. Milne Edwards, 1853, a well known
freshwater crab in Java. Alpheus ruricola is almost
certainly the American gecarcinid land crab Gecarcinus
ruricola (Linnaeus, 1758); while Alpheus maculatus is
likely to be the common Indo-West Pacific carpiliid
Carpilius maculatus (Linnaeus, 1758). Both these names
should not be regarded as new, as Weber almost
certainly obtained them from Linnaeus’ (1758) work. All
four species are relatively stout crabs with weakly to
strongly swollen carapaces. As for Alpheus vitulus, the
name is attributable to Weber, but it has not been used
for over a hundred years and its identity is unknown. The
name is derived from the Latin for a young heifer,
suggesting a stocky and stout species like those listed
near it by Weber. All indications thus are that it is also a
freshwater crab, possibly also a parathelphusid like A.
senex and A. tridens. For this reason, we refer it there.
The name in any case is a nomen nudum and does not
cause any problems.

{7} Potamon (Geothelphusa) perrieri Rathbun, 1904, was
supposedly described from Africa, and has long believed
to be a potamonautid. Recently, Neil Cumberlidge reexamined the types in the Paris Museum. From the
carapace features as well as form of the male abdomen and

SUPERFAMILY GONEPLACOIDEA

Acidops cessacii (A. Milne-Edwards, 1878) [Epimelus]
Acidops fimbriatus Stimpson, 1871
{1} Acidops is a very different from most goneplacoids,
with a primitive sternal condition in which the median
sutures are complete, and research by one of the authors
(D. Guinot, together with M. Tavares and P. Castro, in
prep.) over some years, indicates that it must be
accomodated in its own family. Števi (2005: 36)
independently stated that the genus was so unusual that it
deserved not only its own family but also a superfamily,
Acidopsidae Števi, 2005, and Acidopsoidea Števi,
2005. At the same time, Števi (2005: 70) established the
family Parapilumnidae Števi, 2005, and superfamily
Parapilumnoidea Števi, 2005, for Parapilumnus (sensu
Ng, 2002a), arguing that this genus was peculiar. Števi
(2005) did not compare the two families or genera. This is
despite Ng (2002a: 212), who when redefining
Parapilumnus, commented that “Parapilumnus s. str. in
fact closely resembles Acidops Stimpson, 1971 (type
species Acidops fimbriatus Stimpson, 1871), a genus with
two species (A. fimbriatus and A. cessaci (A. MilneEdwards, 1878)) known only from the Atlantic thus far.
Acidops nevertheless differs from Parapilumnus in many
aspects, most obvious being the carapace having the
regions well demarcated with deep grooves separating
them, the anterolateral margin clearly separated into four
prominent lobes, the fingers of the cheliped not ridged and
grooved, and the carapace and legs far more densely
setose, so much so that the margins and surface are almost
obscured ... The G1 and G2 of Acidops and Parapilumnus
s. str. are very similar in form and general shape ... The
systematic position of Acidops is unclear. Until recently,
authors have placed it in the Rhizopinae Stimpson, 1858,
but Ng (1987), who reappraised this subfamily, formally
referred Rhizopinae to the Pilumnidae, excluded Acidops
from it and transferred it tentatively to the Goneplacidae
instead. Within the Goneplacidae, it fits best in the
Chasmocarcininae Serène, 1964b. On the same rationale,
Parapilumnus s. str. should also be referred to the
Chasmocarcininae as well.” As we have discussed, both
Acidops and Parapilumnus are in a family by
themselves, and not chasmocarcinids. Most importantly,
both genera lack the characteristic supplementary
coxosternal plate present in sternite 8 (see Davie &
Guinot, 1996), a synapomorphy of the chasmocarcinids.
We have examined specimens of both Acidops (Acidops
cessacii) and Parapilumnus (including males of both P.
cristimanus and P. oryctos, see Ng & Chen, 2004b), and
we have no doubt that they should be placed in the same
family. As the Code regards the names Acidopsidae
Števi, 2005, and Parapilumnidae Števi, 2005, are
published simultaneously (being in the same
publication), we hereby select Acidopsidae Števi,
2005, as having priority.

= Parapilumnus Kossmann, 1877 (type species Pilumnus
cristimanus A. Milne-Edwards, 1873, by subsequent
designation by Rathbun (1930); gender masculine)
Parapilumnus cristimanus (A. Milne-Edwards, 1873)
[Pilumnus]
Parapilumnus oryctos Ng, 2002
A point of clarification is also needed on the date and
author of Acidopsidae. Števi (2005) cites the family as
“Acidopidae Števi, in Martin & Davis, 2001”. We find
no indication in Martin & Davis (2001) of the name, and
this must be a mistake. The name was first validly
published by Števi (2005).
Remarks. – The taxonomy of this grouping has changed
substantially in recent years, but despite this, there are still
many problems. Števi (2005), Karasawa & Kato (2003a,
b) and Karawasa & Schweitzer (2006) have rearranged the
superfamily and constituent families substantially,
although there are still many points of contention. Castro
(2007) reviewed the problems associated with their
classifications, and cast doubt on some of their
arrangements. Ng & Manuel-Santos (2007), in
establishing a new family, the Vultocinidae, did a
comprehensive review of the recent classifications
proposed, and used a suite of characters to substantially
clarify the definition of the superfamily and many of the
recognised families.
In the present classification of the Goneplacoidea, we
recognise 10 families: Acidopsidae, Chasmocarcinidae,
Conleyidae, Euryplacidae, Goneplacidae, Lithocheiridae,
Mathildellidae,
Progeryonidae,
Scalopidiidae
and
Vultocinidae. We are uncertain how these families are
related and we have doubts that our Goneplacoidea is
monophyletic. Two of the new families described by
Števi (2005), Raouliidae (for the monotypic Raoulia Ng,
1987) and Typhlocarcinodidae (for the monotypic
Typhlocarcinodes Alcock, 1900), are a problem as they do
not agree well with any of the families recognised here.
They may be distinct families in the Goneplacoidea as
Števi (2005) argued or merely very apomorphic genera
allied to better known families in other superfamilies. For
genera like these whose members are small and very
poorly known, it is imperative that the original specimens
are carefully re-examined, and their sternal, abdominal
and gonopodal characters properly documented, before
firm conclusions are made. Until we better understand
their affinities, we prefer to synonymise Raouliidae and
Typhlocarcinodidae with the Chasmocarcinidae for the
time being.

Notes
{1} In describing Raoulia as a new genus, Ng (1987: 93)
wrote “Raoulia gen. nov. Type-species: Typhlocarcinodes
piroculatus Serène, 1964 (not Typhlocarcinops
piroculatus Rathbun, 1911)”. He subsequently described a
new species, R. limosa with the following synonymy:
“Typhlocarcinodes piroculatus Barnard, 1955: 35, Fig. 16;
Serène, 1964: 237, pl. 21A, Fig. 15 (not Typhlocarcinus
piroculatus Rathbun, 1911; ? Balss, 1938)” (Ng, 1987:
93). Ng’s (1987: 93, 94) discussion of the genus and
species, however, made it clear that he was referring to the
specimen identified as “Typhlocarcinodes piroculatus” by
Serène (1964b) (as well as Barnard, 1955), and not the
true Typhlocarcinops piroculatus Rathbun, 1911. With
regards to Rathbun’s (1911) species, Tesch (1918b) had
referred it to Typhlocarcinodes Alcock, 1900, but Ng
(1987) transferred it to the pilumnid genus Caecopilumnus
Borradaile, 1903. Typhlocarcinops piroculatus Rathbun,
1911, is therefore not the type species of Raoulia Ng,
1987. As the specimen of “Typhlocarcinodes piroculatus”
identified by Serène (1964b) was referred by Ng (1987) to
a new species, Raoulia limosa, this should be regarded as
the type species of Raoulia Ng, 1987. To ensure there is
no misinterpretation in the future, the type species of
Raoulia Ng, 1987, is now fixed (see Article 70.3 of the
Code) as Raoulia limosa Ng, 1987, incorrectly written as
Typhlocarcinodes piroculatus Serène, 1964, in the original
designation by Ng (1987).

the Chasmocarcininae Serène, 1964b, a wholly marine
group. Both subfamilies have the penis lying in either an
enclosed or open groove in sternite 8, such that sternite 8
shows an intercalated plate anteriorly (or the
supplementary coxosternal plate) (see also above
discussion for Acidopsidae and Chasmocarcinidae).
FAMILY CONLEYIDAE ŠTEVI, 2005
Conleyidae Števi, 2005
Remarks. – In establishing Conleyus, Ng & N. K. Ng
(2003: 434) commented that “Conleyus also bears a
superficial resemblance to more typical carcinoplacines
like Intesius Guinot & Richer de Forges, 1981, and
Platypilumnus Alcock, 1894 (see also Richer de Forges,
1996; Ng & Chan, 1997), but its carapace (and G1)
features differ so markedly that we have little doubt that
they are not congeneric. Both these genera are also
typically deeper water taxa, found well below 300 m. In
the form of its male abdomen (all segments freely
articulating), the stout G1 and relatively long G2
(exceeding half the length of the G1) … Conleyus is
clearly a member of the Carcinoplacinae. Some of the
features associated with Conleyus, viz. the poorly
pigmented carapace, elongated ambulatory legs and
relatively reduced orbits are adaptations associated with
obligate cavernicolous animals … These features are also
present in species living in deep waters. Considering the
habitat where Conleyus was collected from, i.e. deep coral
rubble beds, it is not surprising that it has features
associated with such organisms. Nevertheless, on the basis
of just two specimens, not much else can be said about its
preferred habitat.” On the basis of this, Števi (2005)
established a new family and superfamily Conleyoidea
Števi, 2005, and Conleyidae Števi, 2005, for the
genus. Castro (2007) discussed this and argued that
Conleyus was not a goneplacid in the strict sense but left
its status indeterminate. Ng & Manuel-Santos (2007)
listed a suite of unique male abdominal and sternal
characters that showed that the recognition of a separate
family for this genus was necessary, although the
characters listed by Števi (2005) are not valid. Števi’s
(2005) recognition of a superfamily is unwarranted.
Conleyus is still a goneplacoid.
Davie (2002) raised the Trogloplacinae to full family
status. With the recognition here of the Chasmocarcinidae
as a family, we have decided to now treat the
Trogloplacinae
as
a
subfamily
within
the
Chasmocarcinidae because of the similarity in the
supplementary coxosternal plate. There are some notable
differences between the two subfamilies which warrant
their separation. A major difference is that in the
Chasmocarcininae the basal antennular article is very
swollen and completely fills the antennular fossa, such
that the flagellum is excluded and cannot be folded. Also
in the Chasmocarcininae, the G2 is noticeably shorter than
the G1 and the flagellum is more-or-less short, whereas in
the Trogloplacinae, the G2 is as long as or slightly longer
than the G1, and the flagellum occupies about half, or
slightly more, of the length. Finally, the Trogloplacinae is
only known from freshwater and upper estuarine
environments, and has evolved direct development
through to juvenile crab stage, a characteristic completely
apart from other Goneplacidae. Austrocarcinus kanaka,
described from New Caledonia, was recently collected
from shallow clear waters in well forested karst areas,
several hundred metres above sea level near the type
locality in northern New Caledonia (P. K. L. Ng).

FAMILY EURYPLACIDAE STIMPSON, 1871
Euryplacinae Stimpson, 1871
Remarks. – The Euryplacidae is still a “mixed bag” and
needs urgent revision. The series of papers by Guinot
(1969a–c, 1971) clarified the specific and generic identities
of many species which have been allied, linked or placed
in the Euryplacinae or Euryplacidae, but the precise
classifications of several were left unsettled. Some genera
like Trizocarcinus Rathbun, 1914, were placed in the
group with some hesitation while others like Trapezioplax
Guinot, 1969, were only discussed. Trizocarcinus is
unusual in having a relatively broad male abdomen (in
contrast to the narrow ones in most euryplacids) but the G1
condition is more typical of members of the family.
Števi (2005) recognised the family Euryplacidae and
even a superfamily Euryplacoidea, but did not list the
genera included. In describing Xenocrate, Ng & Castro
(2007) also stated the key characters of the family
Euryplacidae (see also Castro, 2007) and they listed 12
genera as provisionally belonging to this family. A revision
of the family is currently in progress by these authors, and
a re-appraisal of all the literature and re-examination of the
material indicates that Trapezioplax, Chasmophora and
Eucratodes are clearly not euryplacids. Trapezioplax is
referred to the Pseudorhombilidae, Chasmophora to the
Panopeidae and Eucratodes to the Xanthidae (see notes for
these families).

THE RAFFLES BULLETIN OF ZOOLOGY 2008
discussing the position of G. maldivensis Rathbun, 1902,
noted that it had clear euryplacid affinities and compared
it with Heteroplax but she did not formally transfer the
species there. Guinot (1971: 1080) also did not include
this species in her list of Heteroplax species, but placed it
her group of “Autres Euryplacinae” as “[Goneplax]
maldivensis Rathbun, 1902” (Guinot, 1971: 1081). Števi
(2005) proposed a new name, Otmaroplax, for this species
but as he did not provide any diagnosis, indication or
explanation, his name is not available for nomenclatural
purposes (see point 1). A revision of Heteroplax and
“Goneplax” maldivensis by Peter Castro and P. K. L. Ng
is currently in progress.

Notes
{1} In the last part of his work, Števi (2005: 133–134)
gave names for many new genera, none of which are
available under the Code. Although he applied formal
Latin names and designated type species, no diagnostic
characters were provided. From our unpublished data, the
two genera listed here would appear to be good taxa, but
they will need to be formally described from material on
hand.
Serène & Lohavanijaya (1973: 72) noted that Stimpson
(1858, 1907) used the masculine gender for Heteroplax
but they inferred this from the way Stimpson (1858)
named the two species, H. dentatus and H. transversus.
However, Stimpson (1858, 1907) did not explicitly state
that the gender of Heteroplax was masculine. As all
brachyuran names ending in –plax are regarded as
feminine (Article 30.1), we are of the opinion Stimpson
(1858) merely mistook Heteroplax for a masculine name.
We here regard Heteroplax as feminine.
{2} Barnard (1950: 283) and Guinot (1969b: 512) have
both commented that Euryplax bevisi Stebbing, 1921, is
not a true species of Euryplax, but its generic affinities
will require the types be re-examined. Števi (2005),
nevertheless, established a new genus, Lipkeplax, for this
species, but the name is not available (see point 1). We
keep the species in Euryplax pending a revision of the
genus.
{3} Stimpson (1858: 94) established the genus Heteroplax
for two new species from Hong Kong, H. dentatus and H.
tranversus. Miers (1879) subsequently described H. nitida
from Korea, and Sakai (1934) added H. nagasakiensis
from Japan. Serène & Lohavanijaya (1973: 93)
commented that the genus was established with H. dentata
as type species but Stimpson (1858, 1907) made no such
indication. However, Guinot (1969b: 511) had discussed
this matter and selected H. tranversus Stimpson, 1858, as
the type species of Heteroplax Stimpson, 1858. Miers
(1879b) queried the validity of Heteroplax and indicated it
may be the same as Eucrate. De Man (1888), Alcock
(1900) and Tesch (1918b) subsequently regarded
Heteroplax as a junior synonym of Eucrate. Balss
(1922b), Sakai (1934, 1939, 1976), Guinot (1969b, 1971),
Serène (1965, 1968), Serène & Lohavanijaya (1973) and
Serène & Soh (1976), however, preferred to keep them
separate. Several authors (e.g. Alcock, 1900; Balss, 1922b;
Guinot, 1969b) have commented on the affinities of H.
dentata with Eucrate and it seems clear that they are
related. Alcock (1900) regards H. dentata only as a
subspecies of Eucrate crenata (see also Campbell, 1969).
Guinot (1969b, 1971), Serène (1968) and Serène &
Lohavanijaya (1973) recognised four species in
Heteroplax: H. dentata Stimpson, 1858, H. transversus
Stimpson, 1858, H. nitida Miers, 1879 (with doubt) and H.
nagasakiensis Sakai, 1934. The matter is compounded by
the fact that Stimpson’s type specimens of H. dentata and
H. transversus are no longer extant. Serène &
Lohavanijaya’s (1973) study of Heteroplax is perhaps the
most detailed to date, and shows that Heteroplax is
unlikely to be congeneric with Eucrate. They had
specimens of H. dentata, H. transversa and H. nitida, and
commented that Goneplax maldivensis Rathbun, 1902, H.
nitida and H. nagaskiensis may be conspecific (Serène &
Lohavanijaya, 1973: 75). Guinot (1969b: 511, 518), in
{4) Psopheticoides Sakai, 1969, is clearly an euryplacid,
with a narrow male abdomen and long slender and spinous
G1s with a short G2 (Castro, 2007).
{5} The family placement of Sotoplax Guinot, 1984 (type
species Sotoplax robertsi Guinot, 1984) described from
Mexico is problematic. It has features of both
Goneplacidae sensu stricto as well as Euryplacidae, but
Guinot (1984) provisionally referred it to the
Euryplacidae. Even so, the G1 is unusual among known
euryplacids in having the tip rounded and armed with
several large spines.
{6} Castro (2007) has commented that Carcinoplax
angusta Rathbun, 1914, is likely to be a euryplacid and is
not a goneplacid sensu stricto. “Carcinoplax” angusta is
perhaps closest to Xenocrate peculiaris Ng & Castro,
2007, and may need to placed in its own genus. Peter
Castro and P. K. L. Ng are currently revising these species
as part of a study of the family.

examined. Guinot (1969b: 518) had already pointed out
that this species is not a goneplacid but a euryplacid. A
new genus, Otmaroplax, was established by Števi
(2005) for G. maldivensis, but as noted in point 5, his
name is a nomen nudum. Guinot (1969b) and Serène &
Lohavanijaya (1973) have both noted the close affinities
of “Goneplax” maldivensis with the euryplacid
Heteroplax and we tentatively transfer it there until the
necessary revisions are made (see Notes for the
Euryplacidae).
Notes
{1} The systematic position of Bathyplax A. MilneEdwards, 1880 (type species Bathyplax typhlus A.
Milne-Edwards, 1880) has always been uncertain, and
placing it in the Goneplacidae has traditionally been
difficult (see Guinot, 1969c: 696, Fig. 100, 101; Tavares,
1996). Not unexpectedly, Števi (2005) established a
new subfamily, Bathyplacinae Števi, 2005, for the
genus. We are still uncertain if such a rank is needed or
what are the real affinities of the genus, but on the basis
of the general facies and form of the gonopods, it can be
accommodated in the Goneplacidae, albeit with some
difficulty, and we tentatively recognise the Bathyplacinae.
{8} The correct spelling for this genus should be
Neommatocarcinus, following the original intent of
Takeda & Miyake (1969b), and not as it is sometimes
spelt, “Neoommatocarcinus” (e.g. Guinot, 1971) (see also
Castro, 2007).
{2} The type genera of the Goneplacinae MacLeay, 1838
(Goneplax) and Carcinoplacinae H. Milne Edwards,
1852 (Carcinoplax), appear strikingly different, however
other genera show many intermediate characters.
Karasawa & Kato (2003a, b) have already synonymised
the two subfamilies, and this is also supported by Castro
(2008).
{9} The classification of Notonyx A. Milne-Edwards,
1873, has not been straightforward. In his discussion on
the taxonomy of the Goneplacidae, Serène (1964a, b)
did not consider it. Later, Serène (1968: 91) transferred
Notonyx to the Rhizopinae Stimpson, 1858, which at
that time was a subfamily of the Goneplacidae. Notonyx
was subsequently assigned to the Goneplacinae by
Serène & Umali (1972) and Serène & Soh (1976) but
without any explanation. Ng (1987), transferred a
redefined Rhizopinae to the Pilumnidae and specifically
excluded Notonyx from the family, although he could
not place it anywhere else. Karasawa & Kato (2003)
also did not consider the genus in their reappraisal of the
Goneplacidae Clark & Ng (2005b) argued that despite
its peculiar carapace shape, all sternal, abdominal and
gonopodal affinities were with the Goneplacinae, and it
should be referred there. Števi (2005) regarded the
superficial differences as major and established a new
family and superfamily, Notonycidae Števi, 2005, and
Notonycoidea, respectively for Notonyx. Castro (in
2007), in his revision of the Goneplacinae sensu stricto,
agrees with us that Notonyx is simply an unusual
member of the Goneplacinae. At least two more new
species are now being described by P. F. Clark and P. K.
L. Ng.
{3} Castro (2007) revised the genus Carcinoplax and
established four new genera; one for C. vestita; one for C.
crosnieri and C. cooki (with three new species); one for C.
longispinosa; and one for C. suruguensis, C. bispinosa, C.
meridionalis and C. victoriensis (with one new species).
“Carcinoplax” angusta Rathbun, 1914, is transferred to
the Euryplacidae, while “Carcinoplax” microphthalmus
Guinot & Richer de Forges, 1981, is a progeryonid (see
notes for respective families).
{4} This species may be a junior synonym of Carcinoplax
eurysternum Guinot & Richer de Forges, 1981.
Carcinoplax ischurodous (Stebbing, 1923) was described
on the basis of a small specimen, and in many species of
this genus marked changes in carapace morphology take
place as size increases.
{5} Števi (2005: 133–134) listed a large number of new
genera, and although he designated type species, none of
them was diagnosed, nor any indication made or
explanations provided. Under the Code, none are available
names. However, it is likely that a number of the species
listed will deserve new generic allocations as Števi
proposed.
{10} Ommatocarcinus elegans Chen, 1998, was referred
to a new genus by Castro (2007). Four new species were
also added to this new genus by him.
{11} Castro (2007) revised the genus Psopheticus. Two
species, P. hughi Alcock, 1900, and P. insignis Alcock,
1900, will be referred to a new genus; while P. insolitus
Guinot, 1990, is synonymised with P. stridulans WoodMason, 1892.
{6} Castro (2007) revised the genus Goneplax and
recognised three new genera; one for G. marivenae; one
for G. renoculis (with two new species); and one for G.
serenei. In this same study, G. megalops Komatsu &
Takeda, 2004, was also synonymised with G. marivenae
Komatsu & Takeda, 2004, by Castro (2007) as the
differences described are related to growth changes.
{12} In his revision of the Goneplacidae, Castro (2007)
transferred G. wolffi Serène, 1964, to Singhaplax, as well
as describe four new species. More species are now being
described by Peter Castro, as well as with Tohru Naruse
(pers. comm.).
{7} A new genus will established for “Goneplax”
sinuatifrons Miers, 1886, by Castro (2007). Castro
(2007) also discusses “Goneplax” maldivensis Rathbun,
1902, and comments that this species should be in a
separate genus but has deferred this action until it is re-
{13} Psopheticus megalops was described from two
specimens from northern Ryukyus in Japan (Takeda,
1999), and Castro (2007) commented that it was not a
81
Ng et al.: Systema Brachyurorum Part I
member of the genus, and on the basis of its gonopods,
probably not even a goneplacid sensu lato. While the
general carapace and abdominal features resemble a
Psopheticus, the chelipeds, and certainly the gonopods
(Takeda, 1989: Fig. 17C–F) do not. The holotype male is a
small specimen measuring only 5.6 by 4.8 mm, but it is
certainly already an adult on the basis of the well
developed G1s. It will need to be re-examined. For the
moment, we leave it in the Goneplacidae as an incerta
sedis.

Notes
{1} The transfer of Litocheira Kinahan, 1856, and
Georgeoplax Türkay, 1983, into a separate family has
been under study by Guinot et al. (in prep.), and there a
suite of characters that warrant this. The G1s of the
species of these two genera are stout and “grapsoid-like”,
being contorted and similar in form to some
Euchirograpsus species (Plagusiidae). In the Plagusiidae,
the antennules fold more-or-less longitudinally, but in
Litocheira and Georgeoplax, the antennules fold obliquely
transversely, although this may be plesiomorphic for these
genera. The general facies of the carapace and pereiopods
of Litocheira and Georgeoplax also superficially resemble
Euchirograpsus species (see Türkay, 1975, 1978, 1983a;
Crosnier, 2001; McCulloch, 1913), however, despite their
apparent links to the Plagusiidae, Litocheira and
Georgeoplax are heterotremes while plagusiids are
thoracotremes. More work will need to be done to
establish relationships and affinities. Števi (2005) was
the first to formally recognise a separate family for these
genera, and his name must be used.

Notes

phylogeny of the Goneplacidae and rearranged the
subfamilial system based on selected extant and fossil
taxa. They established a new subfamily, Mathildellinae
Karasawa & Kato, 2003, for Beuroisia, Intesius,
Mathildella, Platypilumnus and Neopilumnoplax. Later
Karasawa & Schweitzer (2006) elevated the
Mathildellinae to a full family but placed it in the
Portunoidea. Ng & Manuel-Santos (2007) reappraised the
status of several goneplacoid families and subfamilies, and
citing diagnostic male sternal and abdominal characters,

Notes
{1} Castro (2007) noted that Paragalene Kossmann, 1878,
and Progeryon Bouvier, 1922, are not true goneplacines.
Ng & Guinot (1999) had commented that Progeryon is no
more than a peculiar carcinoplacine (now Goneplacinae).
Števi (2005) argues that these two genera needed to be
placed in separate tribes within the Goneplacidae, but
Karasawa & Schweitzer (2006) felt that at least Progeryon
should be recognised in its own family and superfamily.
We point out however that carapace features are unreliable
in many goneplacids (for example Carcinoplax indica and
C. longimana), and the form of the carapace and structure
of the anterolateral margins can change dramatically with
size (large specimens losing the prominent lateral spines
and having an ovate carapace). Ng & Manuel-Santos
(2007) recently showed that the sternal and abdominal
condition of Progeryon is unique and cannot be
accommodated in the Goneplacidae. They retained the
family Progeryonidae in the Goneplacoidea, and also
included Paragalene, whose diagnostic characters
conform with their definition of the Progeryonidae.

Since both names Paragalenini Števi, 2005, and
Progeryonini Števi, 2005, were published together, both
are regarded as simultaneously published under the
present Code. We here select Progeryonini Števi, 2005,
as having seniority over Paragalenini Števi, 2005, in the
event they are recognised as synonymous as in this paper.
{2} Paragalene is also unusual among progeryonids in
that male segments 4 and 5 and fused, with only the
median and lateral parts of the suture still visible. Other
genera have all the sutures well defined (Ng & ManuelSantos, 2007). However, such fusion is also present in
some taxa of Goneplacidae sensu stricto (Castro, 2007),
and we do not believe this character alone is significant
enough to take it out of the family. Admittedly, the G2 of
Paragalene is also atypical in that the distal part is

somewhat compressed laterally, and the carapace features
are very different from other progeryonids. However, as
has been discussed in detail by Ng & Manuel-Santos
(2007), the form of the male sternum, position of the
penis, structure of the press-button and G1 structures all
agree with the others (see also Castro & Ng, in prep.).

{3} Bouvier (1922) described the type species, Progeryon
paucidens, from the Atlantic (near the Mediterranean), and
the first record of the genus from the Indo-West Pacific
was by Crosnier (1976). On the basis of Bouvier’s (1922)
detailed description and figures, there does not appear to
be much doubt that the Atlantic and Indo-West Pacific
species are conspecific, but considering the distances
involved, a revision is clearly desirable. The details of the
male sternum, abdomen and gonopod structures of P.
paucidens remain undescribed.
Notes
{1} The systematic position of Scalopidia is difficult. It
has the general carapace, cheliped and even gonopodal
features of many chasmocarcinids; but it differs markedly
in the way its penis is positioned. In the
Chasmocarcinidae, there is a supplementary coxosternal
plate at sternite 8, enclosing the long penis which starts
from the coxa, exiting in the sterno-abdominel cavity. In
Scalopidia, there is only a narrow groove between thoracic
sternites 7 and 8, in which the long penis sits. The penis
lying in the narrow groove is also calcified. We cannot be
confident that the Scalopidia condition is linked to that of
the chasmocarcinids. Thus for the moment, it is most
parsimonious to recognise it in its own family and use the
available name, Scalopidiidae (see Guinot et al., in prep.).
{4} Castro (2007) has commented that Carcinoplax
microphthalmus Guinot & Richer de Forges, 1981, is not a
goneplacid sensu stricto. A study of a good series of
“Carcinoplax” microphthalmus from the Philippines
suggests that it is in fact a progeryonid. A new genus will
be established for this species (Castro & Ng, in prep.)

FAMILY IPHICULIDAE ALCOCK, 1896
Iphiculoida Alcock, 1896
Remarks. – The recognition of a separate family for
Iphiculus Adams & White, 1849, and Pariphiculus
Alcock, 1896, seems appropriate. First recognised as a
grouping by Alcock (1896), it was ignored by almost all
subsequent workers, although Števi (2005) recognised it
by making it a separate subfamily. We have been aware of
the distinctiveness of this grouping for some years now –
with Iphiculus and Pariphiculus differing markedly from
other leucosiids in several key aspects (see also Serène,
1955, 1956). Guinot (1978: 282; Guinot, 1979: 103, 146)
and Guinot & Bouchard (1998: 653) highlighted the fact
that the abdominal segments of males and females are not
fused; there is no fusion between the thoracic sternum and
pterygostome; the brood cavity is not complete; and, the
episternites do not cover the condyles of the first four
pereiopods, thus only holding the abdomen in place by
juxtaposition and engagment. This mode of abdomen
attachment is very atypical (Guinot & Bouchard, 1998:
653).
Fig. 79. Iphiculus spongiosus, central Philippines (photo: T. Y. Chan)
The difference in female abdomens is particularly stark. In
typical adult female leucosiids, the female abdomen has at
least some of the somites fused (often most of them), and
strongly arched, forming a dome-like plate over the
sternum. The sutures may sometimes be visible (e.g. in
some Parilia species) but the somites are nevertheless
immovable. The thoracic sternal cavity is also deep, and
the anterior part of the sternum is deeply excavated, with
the edges forming a rim, to which the abdomen fits tightly.
This sternal and abdominal structure effectively forms a
“brood-pouch” holding the eggs. As such, when the
abdomen is closed, the eggs are not visible externally and
completely sheltered. The adult female abdomen of
Iphiculus and Pariphiculus species, however, has all seven
segments free and normal in form, is relatively much
narrower and flatter, and does not form any dome-like
structure. Its sternoabdominal cavity is also relatively
shallow, and even in large females, and the anterior part
never develops a rim or edge. Ovigerous specimens we
have examined have most of the eggs exposed and not
enclosed by the relatively narrower abdomen (as in
carpiliids, xanthids, parthenopids and portunids). We
explored the possibility of just retaining these two genera
as a subfamily in the Leucosiidae but because of the
unique female abdominal structure we feel a family-rank
better reflects its level of phylogenetic divergence. The
relationship of the Iphiculidae with the other leucosioids,
and more generally, is now being studied by P. K. L. Ng,
Bella Galil and others.

Ng et al.: Systema Brachyurorum Part I
ourselves encountered problems regularly. Often cited
characters like relative length of chelipeds, degree of
carapace areolation, carapace shape, carapace armature,
epistomial form, and relative length of the maxillipeds
etc., all do not work at the suprageneric level and there are
simply too many intermediates, especially in genera like
Arcania, Pseudophilyra and Randallia. In addition,
several of these characters vary substantially with age (e.g.
Parilia). We thus prefer here to synonymise all three
subfamilies (with Ebaliinae having seniority) until a
complete generic reappraisal can be conducted. While we
believe that it may be eventually possible to recognise
more than one subfamily within our present Ebaliinae, we
are of the opinion that it will be very different from the
system that is now used. In addition, the current use of the
name Philyrinae must be considered in the light that there
are actually three senior synonyms, viz. Myrodinae Miers,
1886, Myroida Alcock, 1896, and Nursilioida Alcock,
1896. Under the present Code, it is possible to maintain
usage of a junior name for a suprageneric taxon, but to do
this now would be premature while the taxon is so illdefined. Two genera, Iphiculus and Pariphiculus have
been transferred to their own family, the Iphiculidae
Alcock, 1896 (see above).

Remarks. – Leucosiids show a very strong cephalic
compression resulting in an apparent shortening of the
cephalic region (Pichod Viale, 1966: 1263–1266). In
addition, the thoracic sternum is wide, with all the sutures
(4/5–7/8) interrupted (Guinot, 1978, 1979), and their
endophragmal skeleton is diagnostic (see Guinot, 1979).
Males have coxal genital openings, but the orifices are
sometimes in a coxosternal position (e.g. Leucosia), and
so are sometimes confused as being sternal (Balss, 1957:
1612; Bouvier, 1940: 205); thus the leucosiids are
heterotreme (Guinot, 1979: 195, Fig. 45 A-C). In all
leucosiids that we have examined, the cheliped has its
ischiobasis completely fused with the merus, without any
trace of a suture (Guinot, 1968b: 163). Ihle (1918) has also
noted the special surfaces of articulation of the appendages
in leucosiids. In the Leucosiinae, in particular, there is a
special mode of holding the male abdomen to the sternum
(see Guinot & Bouchard, 1998: Fig. 19).

The general consensus is that the Leucosiidae contains
four or five subfamilies, viz. Leucosiinae Samouelle,
1819, Cryptocneminae Stimpson, 1907, Ebaliinae
Stimpson, 1871, Philyrinae Rathbun, 1937, and perhaps
the Iliinae Stimpson, 1871 (see Rathbun, 1937; Chen &
Sun, 2002). Of these, only the last has a wholly Atlantic
distribution, the other four occurring in all the major
oceans. The Leucosiinae is perhaps the best defined: the
frontal region and orbits are very narrow transversely, a
well developed thoracic sinus is present, and the G1s are
often contorted to various degrees. The Ebaliinae,
Philyrinae and Iliinae, however, are not well defined, with
the diagnostic characters given by Rathbun (1937), Sakai
(1976) and Chen & Sun (2002) failing to be reliable,
especially when both Pacific and Atlantic genera are
considered. It is also well known that some species
currently placed in Ebalia, Philyra and Nursia cannot be
accommodated in these genera with any confidence, and
many species have in fact been transferred from one to the
other in recent years (e.g. see Takeda & Nakasone, 1991;
Komatsu & Takeda, 2000; Chen & Ng, 2003). The
allocation of the various included genera in one subfamily
or the other has been very subjective and we have

seems to be more like a porcellanid than a brachyuran.
However, Fabricius (1787) compared it with other
leucosiids, suggesting it might be a juvenile or small
species of leucosiid, or even a hymensomatid. There are
too few characters to be sure, and we retain it as an
uncertain species of leucosiid for the time being, albeit
with some reluctance.

{2} The identity of Ebalia discrepans Costa in Hope,
1851 (Hope, 1851: 41) cannot be determined here. The
description is brief, and considering the state of the
taxonomy of the genus, we can only regard it as a doubtful
Ebalia species.
{4} In the ZMUC are type specimens labelled as
Parthenope lar Fabricius, 1798, which are what is today
known as Nursia lar (Fabricius, 1793). Presumably,
Fabricius (1798) had decided that what he had named as
Cancer lar in 1793 may be better accommodated in
Parthenope. This is not surprising as Nursia lar does
superficially look like many parthenopid species.

{5} The 1837 type species designation for Philyra Leach,
1817, is in the series of plates by H. Milne Edwards
95
Ng et al.: Systema Brachyurorum Part I
(1836–1844), in his Règne Animal, not Histoire naturelle
des Crustacés (H. Milne Edwards, 1837). The plate
dealing with Philyra was number 24, and according to
Cowan (1976), this was published in March 1837. In his
plate, H. Milne Edwards used the spelling “Philyra
globulosa”, but this was after a Fabricius name. Fabricius
(1775) first spelt the name as Cancer globus but later
(Fabricius, 1793) changed it to Cancer globosus, although
both names apparently share the same types so should be
regarded as objective synonyms. The first spelling has
priority.
species provisionally placed in Randallia Stimpson,
1897, by Galil (2003), Randallia granulatus Miers,
1886, and Randallia speciosus Chen, 1989, were also
transferred to Tanaoa Galil, 2003, by Ng & Richer de
Forges (2007).
{8} Galil (2003) revised Randallia Stimpson, 1897,
separating it into five genera. One species, Randallia
pustulilabris Alcock, 1896 (together with several
others), was provisionally left in the genus with only
the comment “these species are herein retained in
Randallia s. s. pending further revision, rather than
leave them as incertae sedis” (Galil, 2003: 401). There
is however a nomenclatural problem with R.
pustulilabris that has not been previously mentioned. In
describing this as a Randallia, Alcock (1896: 194)
commented that he “ … thought it justifiable to change
the name of this species from granulosa to
pustulilabris, as Miers, ‘Challenger’ Brachyura (1886)
p. 317 has already used the very similar name granulata
for a species belonging to this genus as here defined”.
Interestingly, in the plates volume, Alcock & Anderson
(1896), wrote on the captions page facing plate 24 the
following: “Fig. 3. – Randallia pustulilabris, Alcock.
Journal, Asiatic Society of Bengal, Vol. LXV. Pt. 2,
1896 (= Leucosilia granulosa, Alcock and Anderson.”
(see Clark & Crosnier, 1992, for the dates of the
various “Investigator” plates). However, on plate 24
itself, all the species figured on the page are also named
at the bottom of the page, and here, the name “3.
Leucosilia granulosa A & A ” is used instead! It
seems obvious that “Leucosilia granulosa” was the
name originally used by Alcock but after he changed
his mind, he altered the name in the description and
captions page to Randallia pustulilabris but not the
headings on the actual plate. Leucosilia granulosa
Alcock & Anderson, 1896, is an available name under
the Articles 12.2.7 and 13.1.3 of the Code. It is
nevertheless, clearly an objective synonym of Randallia
pustulilabris Alcock, 1896, according to Article 72.7
and therefore shares the same type series. Ng & Richer
de Forges (2007) transferred this species to Tanaoa.
{6} The issue with the two names Raylilia Galil, 2001,
and Zarenkovia Chen & Türkay, in Chen, 1996, is
somewhat complicated. Chen (1996: 283) first used the
name “Zarenkovia Chen and Türkay, 1995” when she
treated a species she identified as “Zarenkovia mirabilis
(Zarenkov, 1969)” from the South China Sea. She was
referring to a paper that was at that time still
unpublished, citing it as “Chen H. L. & Türkay, M.,
1995. Brachyuran crabs of Hainan Island (South China
Sea). I. Family Leucosiidae (Crustacea: Decapoda).
Senckenbergiana marit, Frankfura a. M. (in the press).”
(Chen, 1996: 303). The name “Zarenkovia” is a nomen
nudum as it was not described or discussed, although
Randallia gracilipes Zarenkov, 1969, can be regarded as
its type species by monotypy, since it was the only
species mentioned. In 2000, one of the present authors
(P. K. L. Ng) read a manuscript by B. Galil which
described a new genus she proposed to name after the
late Ray Manning and his wife, Lili Manning, Raylilia; a
paper which was due to be published in the Proeedings
of the Biological Society of Washington in 2001 to
honour Manning. Realising that Galil’s “Raylilia” was
the same as Chen & Türkay’s “Zarenkovia” which was
still unpublished at that time, he informed both H. L.
Chen and B. Galil that the matter should be examined to
see if it was possible to prevent an unnecessary
synonymy. However, Chen & Türkay’s paper had
already been submitted to another journal, the Chinese
Acta Zootaxonomica Sinica, and H. L. Chen informed
us that it was already in press and too late to retract it.
Galil’s paper was eventually published in early 2001,
whilst Chen & Türkay’s paper came out in the second
half of 2001. However, Chen & Türkay’s (2001) paper
only treated the six new species they had found and
made no mention of the name “Zarenkovia”. While the
overall situation is unfortunate, there is no
nomenclatural problem as both generic names are
subjective synonyms; the type species of Raylilia Galil,
2001, is Arcania gracilipes Bell, 1855, while that for
Zarenkovia Chen & Türkay, in Chen, 1996, is Randallia
mirabilis Zarenkov, 1969. Chen & Sun (2002), in their
review of the Chinese Leucosiidae, also accepted that
the name Zarenkovia is a nomen nudum and junior
name, and used Raylilia for this genus.
{9} Števi (2005: 133) listed a number of new genera,
with designated type species, however as no diagnoses
were given all are unavailable under the Code. In this case
however, there is no problem as Ihleorandallia Števi,
2005 (type species Randallia pila Tan, 1996) is clearly
identical with Toru Galil, 2003 (type species Randallia
granuloides Sakai, 1961), their type species agreeing in all
key characters.
{10} Leucosia whitei Miers, 1875, is a homonym of
Leucosia whitei Bell, 1855, with the latter having priority.
Haswell (1879) replaced Leucosia whitei Miers, 1875,
with name Leucosia chevretii (incorrectly spelt as
chevertii by most authors) (see also Arnold & George,
1987). Recently, Galil (2005) established a new genus,
Urnalana, for several species previously placed in
Leucosia, including Leucosia whitei Bell, 1855, and
Leucosia chevretii Haswell, 1879.
{7} One species, Randallia serenei Richer de Forges,
1983, synonymised with Tanaoa distinctus (Rathbun,
1893) by Galil (2003) was recently shown to be a
distinct species by Ng & Richer de Forges (2007). Two

Although
the

names
Leucosia
pseudomargaritata Chen, 1987, and Leucosia alcocki
Ovaere, 1987, were published in the same year, through
correspondence, Chen and Sun (2002: 454) established
that L. pseudomargaritata Chen, 1987, has priority over L.
alcocki Ovaere, 1987, which was only published in
December of that year. In any case, Galil (2005)
synonymised both taxa with Urnalana pulchella (Bell,
1855). In the event that L. pseudomargaritata and L.
alcocki are regarded as distinct from U. pulchella, L.
pseudomargarita has priority but must be referred to
Urnalana.

SAMOUELLE, 1819
Remarks. – The concept of the Majidae (or Majoidea) as
used here has changed substantially from earlier concepts,
and needs explanation. There is now a trend, especially in
the Americas, of recognising up to eight families in the
superfamily Majoidea, basically raising to full family
status all the subfamilies so nicely defined for the
American fauna by Garth (1958), viz. Majidae Samouelle,
1819, Epialtidae MacLeay, 1838, Inachidae MacLeay,
1838, Mithracidae MacLeay, 1838, Inachoididae Dana,
1851, Pisidae Dana, 1851, Tychiidae Dana, 1851, and
Oregoniidae Garth, 1958 (see Garth, 1958; Hendrickx,
1995a, 1999; Guinot & Richer de Forges, 1997; Boschi,
2000; Martin & Davis, 2002). However, there has been no
thorough revision of both the Indo-West Pacific and
Atlantic genera, and many of these “families” are in fact
poorly defined. In the Indo-West Pacific, the excellent
revision by Griffin & Tranter (1986) is generally followed
by most workers. However because of the great diversity
of form in the Indo-West Pacific fauna, the characters
Griffin & Tranter used to separate the subfamilies
(families as conceived in the Americas) often seem vague
and subjective. Most workers have great practical
difficulty in using the keys to subfamilies; and often work
directly with specific genera and their allies instead. Those
who are less familiar with the Majidae are more often than
not, left bewildered and confused. Confusion such as this
has compelled recent workers familiar with the Indo-West
Pacific fauna (e.g. Grifin & Tranter, 1986; Ng, 1998; Ng
et al., 2001; Davie, 2002), to recognise only a single
family with numerous subfamilies. While the consensus is
that the majoids are monophyletic (together with the
Hymenosomatidae), the “inaccuracy” of the subfamilial or
familial definitions has been problematic. The recent
“brief reappraisal” by Števi (1994), and elaborated on
slightly in Števi (2005), who established many new
subfamilies and tribes, does not improve the situation.
With so many subfamilies already difficult to distinguish,
having numerous tribes does nothing to help.
extremely
conservative
larval
Members of the Oregoniinae form a distinct assemblage of
perhaps rather primitive majoids: many genera have a
more typical brachyuran form (rather than distinctly
pyriform); lack specialised setae on the carapace or
pereiopods to hold objects of camouflage; possess a male
abdomen in which the distal part is broadened with the
telson prominently “inserted” into the distal margin of
segment 6; and the G1 has a prominent longitudinal
groove, and is distally lined with numerous stout setae
and/or spinules. The Majinae and Mithracinae form a
second group, characterised by the possession of complete
or almost complete orbits, presence of specialised hooked
setae for carrying objects (occasionally absent), and a
relatively broad basal antennal segment. The Inachinae
and Inachoidinae are both very different from other
majoids in the form of their carapace and are superficially
similar to each other, although the published literature
suggests they may not be closely related (see Guinot &
Richer de Forges, 1997); and both can be recognised as
distinct. The Inachoididae was not recognised as a valid
group for many decades until being resurrected by Drach
& Guinot (1982, 1983), followed by a detailed
justification by Guinot & Richer de Forges (1997). There
is no confirmation by larval morphology and, moreover,
there are many similarities between the Inachidae and
Inachoididae. Consequently a complete re-appraisal of
both families may indicate that the Inachoididae is only a
subfamily of the Inachidae. The next group is perhaps the
most heterogeneous and contains the Pisinae, Tychinae
and Epialtinae. We have some difficulty in separating
them – all have poorly developed or no orbits, although
the “line” separating several genera is “grey” at best. The
need to separate obviously related genera like Pugettia and
Rochinia (in Epialtinae and Pisinae respectively) does
seem logical. On the other hand, unusual genera like
Criocarcinus, Picroceros and Stilbognathus (at present in
Tychiinae), while “lacking orbits” are in fact much closer
to more typical pisines (which have incipient orbits). In
any case, these three subfamilies are relatively close to the
Majinae and Mithracinae, with the differences highlighted
here not substantial.
Looking at the subfamilies and families proposed, it is
clear to us that there is an intrinsic morphological pattern
which has been generally overlooked, and four major
groups can be discerned within what is now called the
Majidae sensu lato. Certainly all the majoids (including
the hymenosomatids, assuming they are really majoids)
can be diagnosed in having all the thoracic sternal sutures
(4/5–7/8) interrupted (Guinot, 1977a, b, 1979). In addition
the retaining mechanism of the male abdomen generally
consists of a typical press-button, usually in the form of a
very acute structure, often positioned on the oblique sides
of the sterno-abdominal cavity, with an extremely deep
socket on the abdomen. In certain majoids (for example in
most inachids), abdominal segment 6 is fused to the telson
as a pleotelson so that the sockets are unusually located on
the last element of the abdomen (Guinot & Bouchard,
1998). From what is known, all majoids (again with the
exception of the Hymenosomatidae) have highly
abbreviated larval developments, with two or less zoeal
stages before the megalopa (Rice, 1980; Clark et al.,
With regard to the suprageneric taxa established by
Števi (1991, 1994, 2005), viz. the Planoterginae,
Eurynolambrinae, Pliosomatinae and Thoini, some may be
recognised. Members of the Thoini are nothing more than
rather specialised mithracines and should be transferred
there. The Planoterginae (with only one genus
Planotergum) requires more comment. It has already been
discussed in some depth by Serène (1965b) that
Planotergum has many affinities with the eastern
American mithracine genus Hemus, and the two genera
are clearly closely related (cf. Števi, 1991; Garth, 1958;
Hendrickx, 1999). Planotergum, like Hemus, has a
relatively broad basal antennal article (like other
mithracines) and shares with Hemus, not only a similar
carapace and short, hook-like ambulatory pereiopods, but
also the delicate chelipeds which can be barely seen in
dorsal view, and the prominently foliaceous third antennal
98
THE RAFFLES BULLETIN OF ZOOLOGY 2008
article visible in dorsal view. This suggests that
Planotergum and Hemus should be placed together in the
Planoterginae. Both are close to the Mithracinae, with the
genus Thoe forming a link between the two subfamilies.
Thoe, however, is still better placed in the Mithracinae, at
least for the time being, with its third antennal article not
as prominently enlarged, the ambulatory pereiopods not as
obviously short and hook-like, and the adult male
chelipeds typically elongate. The Pliosomatinae (for only
one American genus Pliosoma) is another matter. Guinot
(1979: 33) states that Pliosoma was clearly a majoid and
likely a pisine, not an atelecyclid as it had been classified
(cf. Rathbun, 1925), a view in which we concur. It
nevertheless differs from typical pisines in its carapace
form, and especially in its upcurved last two ambulatory
dactyli. It is here provisionally recognized as a separate
subfamily, Pliosomatinae). With regards to Eurynolambrus, it is clear from the study by Krefft (1952), that
younger specimens bear a striking resemblance to many
genera of majines like Leptomithrax and Maja, possessing
all the Majinae features noted earlier (see also Griffin &
Tranter, 1986). The adults of Eurynolambrus have a
disproportionately broadened carapace giving the crab a
peculiar, almost “parthenopid” appearance, but its
affinities to the Majinae are indisputable. Guinot (1967c:
840; 1979: 32–33) has already stated emphatically that it
is a majoid. For the moment at least, we recognise the
Eurynolambrinae, but in the Majidae sensu stricto.
With regards to the placement of the Hymenosomatidae
in the Majoidea, this is still somewhat provisional. In
her original synthesis of the modern Brachyura, Guinot
(1978) regarded the hymenosomatids as thoracotremes.
In a later paper, Guinot & Richer de Forges (1997)
suggested they were heterotremes instead. Richer de
Forges et al. (1997) using sperm data suggest they are
close to the majoids. We have had a look at several
hymenosomatid genera to ascertain where the penis is
actually derived, but we are still uncertain. It does
appear that they are more thoracotrematous than
heterotrematous, but we prefer to defer any decision
until a more proper study with better techniques and
more genera can be conducted. The determination of the
penial condition is very difficult in small, highly
decalcified and simplified crabs (including the
cryptochiroids and pinnotheroids), and their condition
may differ from that observed in more typical
thoracotremes like the grapsoids and ocypodoids (see
Guinot, 1979). The available evidence from larvae and
morphology (other than the penial condition) does
suggest a close affinity with majoids (see also Guinot &
Richer de Forges, 1997; unpublished data). We therefore
keep the Hymenosomatidae in the Majoidea for the
moment.
FAMILY EPIALTIDAE MACLEAY, 1838
Larval characters are also providing some useful insights.
Using larval morphology, Clark & Webber (1991) argued
that four families can be recognised, viz. the Majidae,
Inachidae, Oregoniidae and Macrocheiridae (see also Pohle
& Marques, 2000). This view resembles what is proposed
here, including our observations that the Inachoididae is
close to the Inachidae, and the Epilatidae is close to the
Majidae. Pohle & Marques (2000) commented that while
there was some larval support for the Inachoididae, this is
not unambiguous, and there was no larval support for the
Epilatinae, Mithracinae and Pisinae (see also Marques et al.,
2003). At the moment, Macrocheira is classified in the
Inachidae, but admittedly, it is a rather aberrant member of
that family. In addition to its enormous size (the only
species, Macrocheira kaempferi, is generally regarded as the
largest crustacean), and its unusually twisted G1, it differs
markedly from all other inachids, and resembles oregoniids
in many ways. Interestingly, all larval trees show the larvae
of Macrocheira kaempferi as coming out basally. On the
available evidence, there is clearly some support for the
recognition of a separate suprageneric taxon for
Macrocheira kaempferi, however, further study is needed
before we will be comfortable to recognise the
Macrocheiridae as a separate family.

From the foregoing evidence and discussion, we can only
recognise five majoid families with any confidence, viz. the
Majidae (with four subfamilies, Majinae, Mithracinae,
Planoterginae and Eurynolambrinae), Inachidae, Inachoididae, Oregoniidae, and Epialtidae (with four subfamilies Epialtinae, Tychiinae, Pisinae and Pliosomatinae).

{7} Dana (1851c: 433) named the genus “Perinia” but in
his later monograph (Dana, 1852b: 114) used the spelling
Perinea instead. Over the years, both spellings have been
used. We see no reason why the original spelling should
not be retained.
{8} White (1847: 6) listed “Chorinus barbirostris, Leach,
Zool. Misc.” under the synonymy of Chorinus heros
(Herbst, 1790) without comment. Subsequently, Rathbun
(1925: 305) listed “Chorinus barbirostris (Leach MS.)
WHITE, List Crust. Brit. Mus., 1847, p. 6” under the
synonymy of C. heros. The name Chorinus barbirostris,
however, has never been validly published to our
knowledge by Leach or anyone else, and must thus be a
nomen nudum (see Clark & Presswell, 2001). The name is
also unavailable as it was first used as a synonym of
another species by both White (1847) and Rathbun (1925).
Notes
{1} Acanthonyx simplex
“problem” species for a
regarded as a synonym of
locality” (Hawaii) being a
al., 2007).
Dana, 1852, has been a
long time, but it is now
A. petiverii, with the “type
mistake (see Emparanza et
{9} Cancer cruentatus Linnaeus, 1758, has not been used
since its description, but it is sufficiently detailed to make
it clear that it is a synonym of Lissa chiragra (Fabricius,
1775), a well known European species. The ICZN in 1958
suppressed Cancer cruentatus Linnaeus, 1758, in favour
of Cancer chiragra Fabricius, 1775.
{2} Serène & Vadon (1981) used the genus name
Pisidarum, and characterised an unnamed species, noting
that it was like no other genus. But as no named type
species was specified (ICZN Article 13.3), the generic
name is a nomen nudum. Richer de Forges (1994)
formally named the genus Griffinia.
{10} In describing Egeria Leach, 1815, Leach (1815)
listed only one species, Egeria indica Leach, 1815, which
is therefore the type species by monotypy. Miers (1879a)
incorrectly indicated that the type species was Cancer
longipes Linnaeus, 1758.
{3} Miers (1879a: 649) was the first to designate Maja
(Huenia) proteus De Haan, 1839, as the type species of
Huenia De Haan, 1837. Holthuis (1987) showed that this
designation is invalid as Maja (Huenia) proteus De Haan,
1839, was an unnecessary replacement name for both
Maja (Huenia) heraldica De Haan, 1837, and Maja
(Huenia) elongata De Haan, 1837, the two species
originally described when Maja (Huenia) De Haan, 1837,
was established. As such, Maja (Huenia) proteus De
Haan, 1839, cannot be the type species of the genus.
Holthuis (1987), as first reviser, selected Maja (Huenia)
heraldica De Haan, 1837, as the type species.
{11} Latreille’s Encyclopédie Méthodique was published
in two parts; Part 1 (pp. 1–344) on 1 October 1825, and
Part 2 (pp. 345–832) on 13 December 1828 (Evenhuis,
2003: 36, 48). As both Stenopus and Phalangipus were
published on pages 486 and 699, respectively, the
publication date is therefore 1828.
{12} See note {3} in Majidae for Halimus and Naxia.
{4} The date for the publication of Huenia brevirostrata
should be Dana (1851a), not 1852. It is now a junior
subjective synonym of Huenia heraldica (De Haan,
1837).
{5} The date for this species is often cited as 1834, but it
should be 1833 as Leucippa and L. pentagona were first
used in H. Milne Edwards’ (1833) paper, and the species
was figured.
{6} The species Pisa (Leucippa) ensinadae De Haan,
1833, was apparently named from Ensenade Bay, and the
spelling of the species name is therefore wrong. However,
in the original paper, De Haan used the spelling
“ensinadae” consistently throughout and as such, this
spelling must be maintained. Henri Milne Edwards &
Lucas (1843) used Leucippa ensenadae, correcting the
spelling of the species name, but under the Code, the name
cannot be changed as in De Haan’s original paper, there
was no indication of a lapsus.

{4} This species may be a junior synonym of Halicarcinus
ovatus (unpublished data).
{5} Limnopilos Chuang & Ng, 1991, was synonymised
under Hymenicoides Kemp, 1917, by Ng & Chuang
(1996). It was recognised as valid by Naruse & Ng (2007).
{6} What has been widely regarded as one species,
Hymenosoma orbiculare, by most workers (e.g. see Lucas,
1980), is in fact a species complex of at least five taxa in
southern Africa (Edkins et al., 2007). One of these species,
H. geometricum Stimpson, 1858, has been synonymised
under H. orbiculare (see Edkins et al., 2007).

same series of papers (Miers, 1881, No. 47) that same
year. Monod (1956: 562) placed Stenorhynchus rostratus
var. spinulosus in the synonmy of Macropodia rostrata
and wrote (Monod, 1956: 566) that he had seen the types
of Miers from BMNH, and that he was following Odhner
(1923: 18) in not accepting the name.
Notes
{1} In his original description of Camposcia Latreille,
1829, only one species was mentioned and this was spelt
“Maia retuja Latreille, 1829” (Latreille, 1829: 60). This
name was used only once in Latreille (1829), so we cannot
be totally sure it was a mis-spelling. Certainly, the word
“retuja” has no meaning, and not surprisingly, all later
workers (including Latreille himself) used the correct
spelling “retusa”. Camposcia retusa is a well known
species and the name has been widely used in many
marine publications, albeit more in the realm of ethology,
books and aquarium literature. Nevertheless, there is no
good reason to keep the original spelling as it will create
unnecessary confusion. All subsequent workers since
Latreille (1829) have used the name “retusa” and as such,
we enact Article 33.3.1 of the Code (regarding incorrect
spellings in prevailing usage), to keep the spelling as
“Camposcia retusa”.
{7} The status of the genus Pleistacanthoides Yokoya,
1933, is unclear, and although some authors have
recognised it as distinct, more recent ones (e.g. Griffin &
Tranter, 1986; Ahyong et al., 2005) suggest that it is
synonymous with Pleistacantha Miers, 1879, like
Parapleistacantha
Yokoya,
1933.
The
genus
Pleistacantha may need to be split, but new characters will
need to be determined and should be done as part of a full
revision (S. T. Ahyong, pers. comm.).
{8} The original spelling of this genus was Stenorynchus
Lamarck, 1818, but in Opinion 763, the name was
emended to Stenorhynchus with the same author and year,
and the type species was fixed as Cancer seticornis
Herbst, 1788.
{2} Zarenkov (1990) described “Cyrtomaia danieli” from
the Indian Ocean, stating explicity (Zarenkov, 1990: 232)
that the species was named after “D. Guinot”, which is of
course, Danièle Guinot. As it is named after a woman, the
name must be amended to Cyrtomaia danielae.
{9} The name “Ewdawsonia profundorum Webber &
Richer de Forges, 1994” first appeared in a book compiled
by Thompson (1994), on page 168 in Chapter 9 - 'Living
For Ever', as part of a list of living things named after New
Zealand Oceanographic Institute scientists. The name was
used, unfortunately, without the prior consultation of
Richard Webber and Bertrand Richer de Forges, and thus
was a nomen nudum. In that same year the species was
independently named by Zarenkov (1994) as Vitjazmaia
latidactyla. Thus when Webber & Richer de Forges’ paper
was published in 1995, Ewdawsonia profundorum was
omitted because a different valid name was already
available.
{3} Neither Cancer dodecos Linnaeus, 1767, and Cancer
tribulus Linnaeus, 1767, have been used since they were
described, which is surprising as from Linnaeus’
descriptions, it is clear that they are conspecific with
Inachus dorsettensis (Pennant, 1777) and Inachus
phalangium (Fabricius, 1775), respectively. Cancer
tribulus Linnaeus, 1767, has already been suppressed
under ICZN Opinion 708, so it no longer poses a problem.
However for Cancer dodecos Linnaeus, 1767, we invoke
Article 23.9.2 of the Code to conserve the better known
name.
{10} On the basis of the description, Cancer auritus
Fabricius, 1775, certainly belongs to the Majidae. The
type locality was stated as Iceland. The description is too
inadeqate to be able to identify a species, but it indicates
that it is probably an Atlantic species of Macropodia.
{4} Herbst (1782: 224) described Cancer satuak from
Greenland and noted it was close to what was known as
Cancer phalangium Fabricius, 1775. There appears no
good reason not to regard both names as subjective
synonyms.
{5} In describing Stenorhynchus egyptius H. Milne
Edwards, 1834, the species was named “Stenorhynchus
égyptius”, with an accent on the e. Some have spelt it as
“S. aegyptius” but it is clear the original spelling should be
conserved. The species is now regarded as a junior
subjective synonym of Macropodia longirostris
(Fabricius, 1775).
{6} Stenorhynchus rostratus var. spinulosum was first
established by Miers (1881, No. 45: 206), who in a
footnote, named and compared it with Stenorhynchus
rostratus (now Macropodia). The name Stenorhynchus
rostratus var. spinulosus also appears in a later part of the

of the genus and argued that it was a junior synonym of
Hyastenus White, 1847, the problem is not so
straightforward. A detailed account of its history is
necessary to understand why it is now regarded as a junior
synonym of Naxia Latreille, 1825. The name Halimus was
first used as “Helimus” in a footnote by Desmarest (1823)
but it is a nomen nudum as there was no accompanying
description, indication or information on species included.
The name was used again by Latreille (1825a) and
Berthold (1827) as "Halime" and "Helimus", respectively.
As has been discussed in the introduction, Latreille’s
(1825a) paper poses a nomenclatural problem in that all
the names inside are used in the French vernacular (often
indicated by the French accenting), and are thus not
available under the Code. However, Berthold (1827) while
providing essentially a translation of Latreille (1825a),
treats the names rather differently, using them as de facto
scientific names. Latreille (1825a: 272) in a footnote on
his "Halime", commented that "Formé sur deux espèces du
Muséum d’Histoire naturelle, et dont une très-voisine du
cancer superciliosus de Linné. Herbst, Krabb., tab. 14, fig.
89". As noted, Latreille’s (1825a) names are not available.
In his German translation of Latreille (1825a), Berthold
(1827: 258), in a footnote under the name "Helimus",
wrote "Nach zwei Arten, welche sich im Pariser
naturhistorischen Cabinet befinden, und von denem eine
dem Cancer superciliosus, Lin. (Herbst, Tab. 14, Fig. 89)
sehr nahe steht, gebildet". Both Latreille’s (1825a) and
Berthold’s (1827) comments may be translated as follows:
“Established after two species which are in the Cabinet of
natural History in Paris, and on which one is very close to
Cancer superciliosus, Linnaeus (Herbst, Tab. 14, Fig.
89)”. It is, however, clear that both names are also nomina
nuda as there were no accompanying descriptions and no
included species were indicated for "Halime" (viz.
Latreille, 1825a) or “Helimus” (viz. Berthold, 1827).
Latreille (1825a: 272) and Berthold (1827: 258) each
provided a diagnosis for several groups or genera
(Parthenope, Eurynome, Mithrax, Hymenosoma, Pisa,
Stenocionops, Micippa, Maja, Stenops, Hyas and Helimus,
for Berthold, 1827), but as it is not specific for one genus,
it cannot be regarded as a description or even indication of
the genus in question. Both authors also mention Cancer
superciliosus Linnaeus, 1767, in their discussion of this
genus, but do so only to suggest that the species included
in the genus are close to Cancer superciliosus but do not
state that it is a member. In his Encyclopédie Méthodique,
Latreille (1828: 700) uses the latinised name Halimus and
writes essentially the same thing as earlier: “… this genus
is established for two species in the collection of the Jardin
du Roi [= Paris Museum], and of which one seems to be
very close to Cancer superciliosus of Linné ..” (translated
from the French). The name Halimus Latreille, 1828, is
thus a nomen nudum as well, as he neither mentions nor
describes the two species he includes, and a third named
species (Cancer superciliosus) is not definitely placed in
the genus. Later, Latreille (1829: 60) writes nine lines to
define Halimus, and there is a footnote on the same page
which is similar to what has been said earlier, that is that
the genus contains two species, of which one seems very
close to Cancer superciliosus. Article 12.1 of the Code
states that “to be available, every new name published

Notes
{1} There had been a period of time when there was some
confusion over the correct spelling of this genus – Maia
Lamarck, 1801, or Maja Lamarck, 1801. Miers (1879a:
655) had selected Cancer squinado Herbst, 1788, as the
type species; but the ICZN eventually had to make a ruling
on the correct spelling as well as fixing the type species as
Cancer squinado Herbst, 1788 (ICZN, 1958, Opinion
511). In fact, Desmarest (1858: 14) had already selected
Cancer squinado Herbst, 1788, as the type species of
Maja but the ICZN ruling over-rides any other.
{2} Miers (1879a) stated that Naxia serpulifera is the type
species of “Naxia M-Edw.” but the genus was actually
established earlier by Latreille (1828) who listed only one
species, Pisa aurita Latreille, 1828. Pisa serpulifera
Guérin, 1829, which was described a year later, therefore
cannot be the type species. Pisa serpulifera Guérin, 1829,
was designated the type species of Paranaxia Rathbun,
1924, by the original designation.
{3} The nomenclatural history of Halimus is confused.
Although Rathbun (1897: 157–158) provided a discussion
121
Ng et al.: Systema Brachyurorum Part I
Milne Edwards. Pisa aurita. Latr.” (which he figured in
full in colour). Henri Milne Edwards (1834) was therefore
the first subsequent author to identify described species in
Halimus Latreille, 1829. According to Article 67.2.2 of
the Code which states that “if a nominal genus or
subgenus was established before 1931 … without nominal
species [Art. 12], the nominal species that were first
subsequently and expressly included in it are deemed to be
the only originally included nominal species”, H. Milne
Edwards’s (1834) action means that either “Halimus aries.
Latr.” or Halimus auritus (Latreille, 1825) can be the type
species. Because H. Milne Edwards mentioned both
species, and Guérin-Méneville (1844) just figured
Halimus aries, and none of them stated which was the
type species, the first person to validly choose a type
species was actually Rathbun (1897) who selected
Halimus aries. Herein lays a new problem. Whose species
is H. Milne Edwards’ (1834, 1838) and GuérinMéneville’s (1844) “Halimus aries”? Is the “Halimus
aries Latreille” in H. Milne Edwards (1834, 1838) and
Guérin-Méneville (1844) the same taxon as the species
Latreille himself validly named in 1825 as Pisa aries?
before 1931 must satisfy the provisions of Article 11 and
must be accompanied by a description or a definition of
the taxon that it denotes, or by an indication” with regards
to indication, Article 12.2.5 adds that “in the case of a new
genus-group name, the use of one or more available
specific names in combination with it, or clearly referred
to it by bibliographic reference, provided that the specific
name or names can be unambiguously assigned to a
nominal species group taxon or taxa”. In the case of the
above names - Helimus Desmarest, 1823, “Halime”
Latreille, 1825a, Helimus Berthold, 1827, and Halimus
Latreille, 1828, they are not accompanied by a description,
indication or clear inclusion of a valid species. Latreille’s
(1825a) name is not Latin and as such not available. In any
case, while Latreille (1825a), Berthold (1827) and
Latreille (1828) mention Cancer superciliosus Linnaeus,
1767, they do not explicitly say it is a member of the
genus. All four names are therefore nomina nuda. Latreille
(1829) was therefore the first author to validate Halimus
when he effectively provided a diagnosis of the genus,
even though no included species were listed.
Interestingly, Griffith & Pidgeon (1833: 168) recognised a
genus "Kalimus" with only the comments "Two species,
one very near the Cancer superciliosus of Linnaeus",
which is almost certainly copied from earlier texts. As
there was no description, the name "Kalimus" is also a
nomen nudum.
From her discussion, it is apparent that Rathbun (1897)
assumed that Guérin-Méneville’s (1844) ‘Halimus aries?’
(and that of H. Milne Edwards, 1834, 1838) is the same
species as Pisa aries Latreille, 1825. After all, H. Milne
Edwards and Guérin-Méneville had cited Latreille as the
author of the species. However, as mentioned earlier, H.
Milne Edwards (1834: 241) makes it obvious that he
equates Halimus auritus with the Pisa aurita of Latreille
(1825a), but regarded Halimus aries as a separate taxon
and not the Pisa aries of Latreille (1825a). Alphonse
Milne-Edwards (1872) argued that Pisa aries Latreille,
1825, is a member of Hyastenus White, 1847, and this was
apparently followed by all subsequent workers. However,
the specimen illustrated in H. Milne Edwards (1838: pl.
28) and Guérin-Méneville (1844: pl. 9 fig. 2) does not
belong to Hyastenus as defined at present, but is a species
of Naxia Latreille, 1825. Henri Milne Edwards (1838)
himself was clear on this when he affiliated Halimus with
Naxia. The available evidence thus strongly suggests that
Pisa aries Latreille, 1825, is not the same species as
Halimus aries H. Milne Edwards, 1834. Although H.
Milne Edwards and Guérin-Méneville credit the species to
Latreille, H. Milne Edwards (1834) was the first to
validate the name “Halimus aries” and should therefore be
regarded the author of this species. Calman (1913: 312–
314) was the first to realize the confusion between the two
species of “aries” and to challenge Rathbun’s (1897)
assumption that both taxa were the same.
Both Rathbun (1897) and Calman (1913) note that GuérinMéneville on his pl. 9, fig. 2, had provided a labelled
figure of “Halimus aries Latreille” (the only member of
the genus illustrated or mentioned) and regarded GuérinMéneville as the first author after Latreille (1829) to
identify a described species in Halimus Latreille, 1829.
Neither provided dates although other authors have
identified possible dates as 1829 or 1834. They are
incorrect. Guérin-Méneville’s “Iconographie” was
published over a period of 15 years (1829–1844), and the
date for the Crustacea volume is 1844, with 48 pages and
35 plates (see Cowan, 1971). As such, Guérin-Méneville’s
formal recognition of “Halimus aries Latreille” was
actually in 1844. This means that there are at least two
earlier reports by H. Milne Edwards that list “Halimus
aries Latreille” in 1834 and 1838. In listing “Halimus
Latreille”, H. Milne Edwards (1834: 241) included two
species, “Halimus aries Latreille” and “Halimus auritus
(Latreille)” but did not indicate a type species. He placed
Latreille’s name in brackets for H. auritus, suggesting a
generic transfer, and in a footnote on the same page, he
commented that his Halimus auritus was the same as Pisa
aurita Latreille, 1825 (from his Encyclopédie Méthodique,
see later). Significantly, he did not place Latreille’s name
in brackets for H. aries or comment anywhere it was the
same species as Pisa aries Latreille, 1825, but instead
noted in a footnote that it was the same as “Halimus aries
Latr. in Guérin-Méneville”. Although H. Milne Edwards
(1834) cites Guérin-Méneville’s work which was actually
published later in 1844, he probably had an unpublished
draft copy. Subsequently, H. Milne Edwards (1838: pl. 28)
listed and figured two species as belonging to Halimus,
“H. aries. Latr.” (partially figured) and “Halimus auritus.
Subsequent majid workers have generally followed
Calman’s arguments and placed Halimus Latreille, 1825,
in the synonymy of Naxia Latreille, 1825 (see Griffin,
1966; Griffin & Tranter, 1986).
An additional note is needed. As has been discussed
elsewhere, Latreille’s Encyclopédie Méthodique was
published in two parts, one in 1825, and another in 1828
(see Evenhuis, 2003: 36, 48). Naxia was first used on page
140, and as such it is in part 1, i.e. it was published in
122
THE RAFFLES BULLETIN OF ZOOLOGY 2008
1825. The names Pisa aurita Latreille and Pisa aries
Latreille were also used on page 140, and as such their
dates should also be 1825. Latreille’s use of Halimus,
however, is 1828, as the name first appears on page 700,
in part 2 of the Encyclopédie Méthodique.
{8} Most authors cite Miers (1879a) selection of Micippa
platipes Rüppell, 1830, as the first designation of a type
species for Paramicippa H. Milne Edwards, 1834. This
was actually done earlier by E. Desmarest (1858: 14) with
the same species selection. Paramicippa H. Milne
Edwards, 1834, is currently regarded as a junior subjective
synonym of Micippa Leach, 1817.
Summarising this confused history, we here follow
Calman (1913) in regarding Halimus aries H. Milne
Edwards, 1834, as the type species (through subsequent
designation by Rathbun, 1897) of Halimus Latreille, 1829.
This would make Halimus Latreille, 1829, a junior
subjective synonym of Naxia Latreille, 1825, whose type
species is Pisa aurita Latreille, 1825. With regards to
Cancer superciliosus Linnaeus, 1767, it was referred to
Criocarcinus H. Milne Edwards, 1834, and is the type of
that genus by monotypy.
{9} The type species of Mithrax Desmarest, 1823, was
selected as Cancer aculeatus Herbst, 1790, by H. Milne
Edwards (1838: pl. 27). E. Desmarest (1858: 14) lists
“Mithrax dicotomus Latr.” as the type, but to our
knowledge this name has never been published, and so
must be regarded as a nomen nudum.
{10} The status of these three species is difficult to
resolve. The lectotype of Cancer aculeatus Herbst, 1790,
is probably conspecific with Mithrax pilosus Rathbun,
1892, and should have priority. Cancer aculeatus
Fabricius, 1793, is also probably a junior synonym, but its
type is no longer extant. The lectotype of Cancer
aculeatus Herbst, 1790, is here regarded as the neotype of
Cancer aculeatus Fabricius, 1793, making both names
objective synonyms.
{4} In naming Paramithrax, H. Milne Edwards (1834) did
not designate a type species. E. Desmarest (1858: 14)
subsequently nominated Pisa barbicornis Latreille, 1825,
as the type species. Miers (1879a) selected Paramithrax
peronii H. Milne Edwards, 1834, as the type species, but
his action is preceded by E. Desmarest (1858) and
therefore invalid. This is fortunate as Griffin (1963) had
established a new genus, Notomithrax Griffin, 1963, with
Paramithrax peronii H. Milne Edwards, 1834, as the type
species. As a result, both generic names can still be used.
{11} Desmarest (1823: 266), in a footnote, validated the
name Stenocionops first used in an unpublished
manuscript by Leach that had been made available to him.
He included “maia taurus” in the genus and provided a
diagnosis. He also mentioned that “M. Latreille lui
rapporte le cancer corundo [sic. = cornuto] d’Herbst.”
Therefore it must be considered that he included two
species within Stenocionops. This necessitates the present
selection of a type species for the genus, despite the fact
that the two species mentioned are both junior subjective
synonyms of Stenocionops furcata (Olivier, 1791). Later,
Latreille (1829, footnote p. 60) commented that Desmarest
had made a mistake in selecting Maia taurus as the type
and designated Cancer cervicornis Herbst, 1803, as the
type of Stenocionops instead. Cancer cervicornis Herbst,
1803, was not among the species identified by Desmarest
(1823) as belonging to Stenocionops and is currently the
type species of Ophthalmias Rathbun, 1897. Latreille’s
(1829) action thus has no validity.
{5} Ng et al. (2001) highlighted the fact that Prismatopus
Ward, 1933, is a senior synonym of Thacanophrys Griffin
& Tranter, 1986. Griffin & Tranter (1986) established
Thacanophrys for many species previously placed in
Chlorinoides Haswell, 1880, or Acanthophrys A. MilneEdwards, 1865, and designated Chorinus aculeatus H.
Milne Edwards, 1834, as its type species. Since Chorinus
aculeatus H. Milne Edwards, 1834, and Prismatopus
albanyensis Ward, 1933 (type species of Prismatopus
Ward, 1933), are regarded as congeneric, Prismatopus
Ward, 1933, has priority over Thacanophrys Griffin &
Tranter, 1986.
{6} Maja rosselii Audouin, 1826, was described from the
Red Sea, and the simple figure provided suggests it is a
species of Pseudomicippe. It is very close to P. nodosa
and may be conspecific. The types of Maja rosselii,
however, are no longer extant and the figures are
insufficient to make a clear decision on its status.
{7} Marion de Procé (1822) described the spider crab
Inachus inflexus from Manila in the Philippines. On the
basis of his description, Inachus inflexus fits best what is
today known as Micippa platipes Rüppell, 1830, a
relatively common species in the Indo-West Pacific, and
we synonymise them. With regards to Inachus bifidus
Marion de Procé, 1822, also from Manila, his description
best fits the common Schizophrys aspera (H. Milne
Edwards, 1834) and we also synonymise these. The types
of both species are no longer extant (see discussion for
Portunus tropicalis Marion de Procé, 1822).

Notes
SUPERFAMILY ORITHYIOIDEA DANA, 1852
{1} In using the name Orithuja, Weber (1795: 93) made it
clear that he referred to Cancer mammillaris of Fabricius
(1793: 465). Although there is no description, it is a valid
indication under the Code, and the name Orithuja Weber,
1795, is available. Fabricius (1798: 363) subsequently
used the genus name as new but spelt it as Orithyia. Both
Weber (1795) and Fabricius (1798) have published similar
generic names, taking them from the same manuscript
notes of the naturalist Daldorff, and that explains the
different spellings used by these two authors.
FAMILY ORITHYIIDAE DANA, 1852
Orithyiinae Dana, 1852
Remarks. – The recognition of a separate superfamily for
the Orithyiidae which contains just one genus and one
species is deemed necessary as it is a singularly unusual
taxon (see also Števi, 2005). It appears to have affinities
with the Calappidae and Matutidae (Calappoidea), but
nevertheless possesses so many other peculiar features, its
relationships are by no means clear and they are probably
not closely related (see Bellwood, 1996). Female
specimens are also unusual in having a relatively narrow
and short abdomen which expose the vulvae (see Guinot,
1979), a condition otherwise seen in the Cheiragonidae
(see Ng, 1998).
Etymologically, the genus is named for a daughter of
Erechtheus, king of Athens, who was abducted by the
Greek God of the northwind, Boreas, to whom she bore
two daughters and three sons. Her name is variously
written as Oreithuia, Orithyea, Orithyia, Orithye,
Oreithyea and Oreithyia.
Orithyia sinica has a very unusual distribution – it occurs
along the continental waters of East Asia from Hong Kong
up to South Korea, but is absent from the adjacent island
systems of Taiwan, Ryukyus and Japan to the east (see
Sakai, 1976; Miyake, 1983; Ng et al., 2001). This is
despite the fact that the landmasses are very close, it is a
shallow water species and the larvae are completely
planktonic (see Hong, 1976). The absence of this species
is not an artifact of sampling as it is a well known, easily
recognised animal living in shallow waters and could not
have been missed. The fact is that there are no known
records of Orithyia sinica from these island systems in the
200 years of modern research, or any old documents that
suggests its presence there. That it is well known and quite
common on the continental waters just a few kilometers to
the west is noteworthy.
Not surprisingly, Fabricius, who was better known than
Weber, was generally considered the author of the taxon in
question, i.e. most workers used the name Orithyia of
Fabricius. The spelling of the genus was often erroneous,
however, the spelling Orithuja from Weber (1795) has not
been used ever since. Only Latreille (1803: 150) wrote
“orithuia” in the list of the names given by Daldorf (sic;
see discussion of Weber versus Fabricius in Introduction),
but (p. 155, 156) he indicated “orithyie” and Orythyia.
Elsewhere and later, Latreille (1803: 129, 130; 1806: 42)
changed the spelling to Orithyia, without mentioning any
author name. Latreille (1811) also listed “Orithyia” in his
later works (see Evenhuis, 2003: 36, Appendix 3, for dates
of this tome), and was even incorrectly credited with the
authorship of the genus, as comments Evenhuis (2003: 16,
footnote): “Subsequent entries in this volume [vol. 8 of
Olivier] credited to Latreille include the following genera:
‘Orithyia’ (p. 537), …”.
Orithyia sinica is fished wherever it occurs and can
command good prices in the local markets, although it is
rarely harvested in large numbers. In mainland China, it is
referred to as the “tiger face crab” while in South Korea, it
is known as the “tiger crab”, alluding to its striped legs
and large eyes. Fishermen indicate that it prefers rocky
areas and are usually caught with tangle nets. In the
aquarium, they dig themselves partially into sand with
their spatuliform feet but never deep enough to completely
cover their bodies. They prefer to press themselves against
rocks or under hard debri even when half-buried. They
cannot swim like matutids or portunids, and the legs are
clearly an adaptation for digging (P. K. L. Ng,
unpublished data). Little else is known about its behaviour
or biology.
As discussed earlier, the question of authorship, Weber
(1795) or Fabricius (1798), has been adequately resolved
for almost all brachyuran cases, thanks to several
nomenclatural acts submitted by L. B. Holthuis to the
ICZN. The only unresolved case remains that of Orithuja
Weber, 1795 versus Orithyia Fabricius, 1798. As
discussed, the ICZN had considered the question of
Weber’s names, and one of the examples commented on
was Orithyia (spelled as Orithuja), and this is worth
quoting: “For instance, on p. 93, Weber gives the
following: ORITHUJA mammillaris (Cancer F.). This
clearly means that mammillaris is the Cancer mammillaris
as given by Fabricius in his Entomologia systematica [see
p. 465, no. 91], and as Orithuja is cited with only one type
species, Orithuja is a monotypic genus, hence it is given
with a definite “citation or designation of a type species”,
therefore it is published in accordance with the provisions
of Art. 25 and must be considered. Similar cases are:
Symethis (p. 92), Euryala (p. 94).” (ICZN, 1938, Opinion
17: 40–41). Clearly, the ICZN regarded Orithuja as a valid
name, which it is. In fact, van Cleave (1943: 236), in his
review of the opinions rendered by the Commission, listed
Orithuja among the names for which the ICZN had made
Orithyia Fabricius, 1798
= Orithuja Weber, 1795 (type species Cancer
mammillaris Fabricius, 1793, by monotypy; gender
feminine) {1}
= Orithyia Fabricius, 1798 (type species C mammillaris
Fabricius, 1793, by monotypy; gender feminine)
Orithyia sinica (Linnaeus, 1771) [Cancer]
= Cancer bimaculatus Herbst, 1790
= Cancer mammillaris Fabricius, 1793
125
Ng et al.: Systema Brachyurorum Part I
a ruling. This is not the case, with Opinion 17 dealing
primarily with the issue of whether Weber’s names are
valid, but accepting Orithuja Weber, 1795, as an available
name. Consequently, and rightly so, neither names,
Orithuja Weber, 1795, or Orithyia Fabricius, 1798, appear
in the ICZN Official Lists of Names (ICZN, 1987).
In Weber (1795) and Fabricius (1798), the only included
species, thus type species by monotypy, is the same, i.e.
Cancer mammillaris Fabricius, 1793 (p. 465) (not
Fabricius, 1798 (p. 363) as generally indicated by most
carcinologists). Since Cancer sinicus Linnaeus, 1771, is
only a subjective senior synonym of O. mammillaris, the
type species remains as Cancer mammillaris Fabricius,
1793. A note on the spelling of the name of Fabricius’
species is worthwhile. Latreille’s (1810: 422) spelling of
the species name, “Orithyia memmillaris”, is clearly a
mistake.

To revert to the name “Orithuja”, however, will cause
significant confusion, especially since the genus name is
also the basis of the familial name Orithyiidae Dana, 1852.
While it would have been convenient to invoke Articles
23.9.1 and 23.9.2 of the Code in having Orithuja Weber,
1795, suppressed in favour of the better known name
Orithyia Fabricius, 1798, we find that this is not possible.
Article 23.9.1.2. (i.e. “the junior synonym or homonym
has been used for a particular taxon as its presumed valid
name in at least 25 works, published by at least 10 authors
in the immediately preceding 50 years and encompassing a
span of not less than 10 years”) is easy to fulfil, and we
append a list of 31 publications that have used the spelling
Orithyia to support this case. A more detailed search of
Chinese and Korean literature will certainly uncover even
more references as the species is well known in East Asia
and commercially harvested for food. The use of the name
“Orithuja” by van Cleave (1943: 236), however, makes us
unable to fulfil Article 23.9.1.1 which states that “the
senior synonym or homonym has not been used as a valid
name after 1899”. The only course of action is therefore to
ask the Commission to use its Plenary Powers to suppress
Orithuja Weber, 1795. This is now being done.

SUPERFAMILY PALICOIDEA BOUVIER, 1898
Remarks. – This group is traditionally regarded as one
family with two subfamilies, Palicinae Bouvier, 1898, and
Crossotonotinae Moosa & Serène, 1981 (see Castro,
2000), but an ongoing study of the sternum, abdomen,
gonopodal and penial structures of this group by one of
the authors (D. Guinot), with M. Tavares and P. Castro (in
prep.), shows that the two should be recognised as full
families. Certainly, there is a sharp gap between the two
groups morphologically, suggesting deep rooted lineages.

Remarks. – The correct authorship for this family has
been confusing. The name Palicidae Rathbin, 1898, has
been placed in the Official List of Valid Names, but in his
revision of the family, Castro (2000: 444) cited comments
by L. B. Holthuis which demonstrated that there was a
senior name. Holthuis noted that Bouvier’s (1898a)
English translation of his 1897 paper had an additional
footnote which used the name of a tribe, “Palici”, for the
first time. This paper was published in January 1898 and
validated the name Palici. In another publication, Bouvier
(1898b) formally used name Palicae, which is also valid,
but as this paper was not dated, following the Code, the
accepted date had to be 31st December 1898. As the name
Palicidae Rathbun, 1898, was published in June 1898, it is
junior to Palici Bouvier, 1898a. We follow Castro (2000) in
recognising Bouvier (1898a) as the author of the family.

Notes
{1} Henri Milne Edwards (1836: caption pl. 26, fig. 3)
commented that under a figure of Cancer horridus
Linnaeus, 1758: “Parthenope proprement dit” (see Cowan,
1976, for dates). While this statement is not really
equivalent to a type species designation, as has been
discussed earlier, the title of his series of papers makes it
clear that type species are figured. The ICZN ruled in
Opinion 696, that H. Milne Edwards’ selection was valid,
thereby fixing this type designation for Parthenope
Fabricius, 1798, but not its senior homonym, Parthenope
Weber, 1795. Rathbun (1904) established a new name,
Daldorfia, to replace Parthenope Fabricius, 1798.
Holthuis (1962b) provides a detailed discussion of the
complexities of this problem (see also S. H. Tan & Ng,
2007a).

have no doubt that it is a senior synonym of the better
known Lambrus tumidus Lanchester, 1900. Both names,
however, are junior synonyms of Enoplolambrus pransor
(Herbst, 1794) (unpublished data).
figured by De Haan (type locality Japan) and the supposed
holotype figured by Yamaguchi & Baba (1993) are
different. The figure by De Haan agrees with what is now
generally regarded as this species, and indications are also
that it is a senior synonym of Lambrus pisoides Adams &
White, 1848, and Lambrus sculptus A. Milne-Edwards,
1872. The specimen figured by Yamaguchi & Baba
(1993), however, does not look like any known
Aulacolambrus species. In fact, it agrees extremely well
with Parthenopides massena sensu lato, a species (and
genus) known only from the Mediterranean and eastern
Atlantic. It is thus clear in this case that somewhere during
its history, a specimen of P. massena had been
accidentally and incorrectly labelled as the "type" of A.
diacanthus; and the present "holotype" is clearly not a
type specimen. There is thus, no extant type for
Parthenope (Lambrus) diacanthus De Haan, 1837.
Interestingly, L. B. Holthuis writes “In the old days, it was
the rule in the Rijksmuseum van Natuurlijke Historie, that
all material of the museum (even types) was shown to the
public. For this purpose, many of the crabs were preserved
dry and mounted on pieces of cardboard. On either side of
the specimen, a small hole was made in the cardboard and
through these a thread was brought to tie the specimen to
the cardboard. In this way, several specimens were
attached to a single large piece of cardboard. The
cardboards were placed in an oblique position so that the
specimens were more easily viewed. A label with the
information on the specimen was pasted below the
specimen. After a long time, the threads would deteriorate
and break, and the specimens would slither down the
slope. Later, all dry specimens were placed in small boxes.
But when that was done, it was often difficult to decide
which label belonged to which animal, and sometimes,
this was guessed wrongly and the labels came to a species
which was different from that named on the label. I am
sure that this also happened to Parthenope diacanthus De
Haan, which probably (if still extant) will be found in the
dry collection under the name Parthenope massena.” (in
litt, 24 May 2007).
{7} Ng (1996) left the generic position of Parthenopoides
pteromerus Ortmann, 1893, unresolved, though he hinted
that it was close to Garthambrus. A good series of
specimens in recent years have shown that it is no more
than a slightly aberrant species of Garthambrus but should
be referred there (McLay & S. H. Tan, in press).
{8} The strange looking genus Lambrachaeus Alcock,
1895, has always been difficult to classify. Alcock (1895)
left it in the subfamily Inachinae, Majidae. Edmondson
(1952) had his doubts and suggested that it should be
moved to the Parthenopidae. Griffin & Tranter (1974)
questioned its place in the Majidae, and finally stated
emphatically that it was not a majid (Griffin & Tranter,
1986), although they did not decide where to put it.
Hoover (1999) left the genus in the Parthenopidae
without comment, probably following Edmondson
(1952). Števi (1994), however, argued that it was still a
majid and felt that it needed to be classified in its own
tribe in the Inachinae and established the Lambrachaeini.
Ng et al. (2001) left the genus in the Parthenopidae in the
subfamily Lambrachaeinae without comment. With a
good series of specimens, Ng & McLay (2003)
redescribed the genus and discussed its affinities in depth.
They argued that Lambrachaeus was clearly a
parthenopid, albeit with several unusual features, many
superficially resembling majids. But they provided clear
evidence that Lambrachaeus was closely related to
parthenopids like Rhinolambrus. They commented that “it
seems best to regard it as a distinct subfamily,
Lambrachaeinae, in the Parthenopidae, for the time
being” (Ng & McLay, 2003: 902). Števi (2005: 6) cited
Ng & McLay (2003) in his synopsis of the Brachyura, but
he did not discuss or refute their arguments. Števi
(2005) nevertheless maintained that Lambrachaeus was a
majoid in his work, and decided that it should be
recognised as a family, Lambrachaeidae, in the Majoidea.
Looking at the Parthenopidae as a whole, S. H. Tan has
shown that Lambrachaeus merely represents the extreme
end of a morphological cline already shown by many
atypical Rhinolambrus species. The recognition of a
Lambrachaeidae or Lambrachaeinae is unwarranted.
Lambrachaeus is just an anomalous parthenopine
(unpublished data).
{4} Three rather aberrant species: Heterocrypta
caledoniana Garth in Holthuis, 1959, H. maltzani Miers,
1881, and H. occidentalis (Dana, 1854), were recently
reappraised by S. H. Tan & Ng (2007b). Threee new
monotypic genera, Distolambrus, Costalambrus and
Latolambrus, were established for them.
{5} Ng (1996: 157, 158) noted that the Atlantic and IndoWest Pacific taxa differed in a number of carapace and
pereiopodal characters, and the name should be restricted
for the American species. That would mean the Indo-West
Pacific taxa be transferred to Enoplolambrus. This
classification is followed here. S. H. Tan & Ng (2007b)
revised these species and transferred many of the
American species to two new genera, Spinolambrus and
Piloslambrus. Lambrus triangulus is now in Piloslambrus,
the original assignment to Ochtholambrus being incorrect
(see S. H. Tan, in press).
{9} The genus Pseudolambrus is currently a “dumping
ground” for any parthenopid species which has relatively
short chelipeds and cannot be easily fitted into other
genus. S. H. Tan & Ng (2007b) removed many of the
more different members from the genus into the
resurrected Parthenopoides and to two new genera
Ochtholambrus and Velolambrus.
{10} Parthenope nummiferus Rathbun, 1906, and
Lambrus petalophorus Alcock, 1895, have long been
placed in Rhinolambrus but S. H. Tan & Ng (2007b)
recently transferred them to Patulambrus.

{11} In naming Parthenope spinimana from Mauritius,
Latreille (1812: 278) noted that Herbst (1804) had already
named the species Cancer contrarius, although he did not
explain why he offered a new name. Interestingly,
Desmarest (1823), in naming Lambrus spinimanus, refers
to Herbst’s (1804: pl. 60 fig. 3) figure which also depicts
Cancer contrarius. It would appear that all are referring to
one species, and the oldest name by Herbst has priority.

taxonomy of its many species is still far from settled (see
Ng, 1987; Ng & L. W. H. Tan, 1988; Ng & Davie, 1991;
Yeo et al., 2004). In any case, members of the genus
Heteropilumnus De Man, 1895, are now placed in the
subfamily Rhizopinae Stimpson, 1858 (see Ng, 1987;
Davie, 2002), a subfamily not considered by Serène
(1984), and as such, Heteropilumninae Serène, 1984, falls
into its synonymy. Ng (1987) reviewed, partially revised,
and formally transferred the Rhizopinae into the
Pilumnidae. He, however, emphasised that a monophyletic
origin of the Rhizopinae has not been demonstrated,
although all are clearly pilumnids.

protrudes from the condyle of the fifth ambulatory coxa
(Guinot et al., in prep.). The known larval evidence
strongly supports this classification, the zoeal characters
being extremely conservative for the group (see Ng &
Clark, 2000b, for review; and Clark & Ng, 2004, 2005a;
Ng & Clark, in press). Within the Pilumnoidea, a few of
the recognised subfamilies are so distinct that we are
confident that they can be recognised as families. It seems
best to discuss the status of the various
subfamilies/families that we now refer to this superfamily.
The Heteropanopioida Alcock, 1898, has in the recent
past been treated as an Alliance within the Pilumninae,
Xanthidae (Sakai, 1976), and more recently as a
subfamily of the Pilumnidae by Serène (1984). It was
recognised by the following combination of characters:
carapace broadly ovate; dorsally convex; smooth or
weakly granular; regions not, or only weakly, indicated;
anterolateral margins with three broad teeth or lobes
(never spinose); posterior margin narrow; chelipeds
dissimilar, smooth or weakly granular. The generic
composition of the group has varied considerably
between authors, including genera as widely divergent as
Panopeus H. Milne Edwards, 1834, Glabropilumnus
Balss, 1932, and Parapilumnus Kossmann, 1877 (now in
the Acidopsidae), all of which we now know to have no
close relationship to Heteropanope. We considered
retaining the taxon and restricting it for the following
four genera: Benthopanope Davie, 1989, Eurycarcinus
A. Milne-Edwards, 1867, Heteropanope Stimpson, 1858,
and Pilumnopeus A. Milne-Edwards, 1863. The broadly
oval, smooth carapaces of the species in these genera
superficially seem to give the group a coherent
appearance, but unfortunately we have been so far unable
to find any strong characters that can be considered
apomorphic for the Heteropanopinae. As shown by
Davie (1989) the genus Benthopanope has a different
shaped thoracic sternum which also belies a close
relationship with Heteropanope, in which most of the
Benthopanope species had previously been included.
Eurycarcinus is also poorly defined and in need of
characters to adequately separate it from Heteropanope.
We therefore place all the “heteropanopine” genera back
into the Pilumninae sensu stricto until future evidence
proves otherwise.
In the first major change, Guinot (1969a–c, 1971, 1978),
suggested that the subfamily Rhizopinae Stimpson, 1858,
typically classified under the Goneplacidae, had what she
called "pilumnien" tendencies. She also implied that
genera like Halimede, Galene and Parapanope (which she
placed in her “Rameau halimédien”) were closely
affiliated to the true pilumnids but did not propose a
classification for them (see also Guinot, 1969a–c, 1971,
1985b; Guinot & Ng, 1988). In the first major
reclassification of the Pilumnidae, Serène (1984) proposed
a revised classification in which he recognised five
subfamilies:
Pilumninae
Samoeulle,
1819,
Heteropanopeinae Alcock, 1898, Halimedinae Alcock,
1898,
Planopilumninae
Serène,
1984,
and
Heteropilumninae Serène, 1984. Serène’s (1984) book,
however, dealt mainly with the Xanthidae sensu stricto
and Menippidae, and specifically excluded a detailed
treatment of the Pilumnidae. The book was put together
after Dr. Serène had passed away, and Alain Crosnier,
who saw the manuscript to completion, followed Serène's
notes and decided to include his new classification,
including that for the Pilumnidae. Crosnier briefly
explained this in a footnote, and effectively provided the
definitions of both the new subfamilies. Under the
previous Code (1985), both of Serène’s (1984) new
subfamilies are valid taxa, although type genera were not
formally designated.
It is pertinent to briefly discuss each of the subfamilies
recognised
by
Serène
(1984):
Pilumninae,
Heteropanopeinae, Halimedinae, Planopilumninae and
Heteropilumninae. The type species of the type genus of
the Planopilumninae Serène, 1984, Planopilumnus
spongiosus Balss, 1933, is not a pilumnid. It is in fact a
pseudoziid (see discussion for the Pseudozioidea). As
such, taxa previously referred to the genus and the
subfamily must be revised. Some species previously
referred to Planopilumnus by Balss (1933) and later
workers are clearly pilumnids and have been referred to a
new genus (see later). These pilumnid taxa, however, are
clearly referable to the Pilumninae sensu stricto as
conceived at present. The Heteropilumninae Serène,
1984, is similarly, a heterogeneous grouping and the
The Halimedinae is an unusual grouping and we here treat
it as a good family level grouping with several genera.
There are several suprageneric names associated with this
grouping – Galenoida Alcock, 1898, Halimedoida Alcock,
1898, Denthoxanthinae Števi, 2005, and Parapanopini
Števi, 2005; with Galenoida and Halimedoida published
in the same paper (Alcock, 1898). As first revisers, we
select Galenoida Alcock, 1898, as having priority when
these names are regarded as synonyms, and use Galenidae
for this family. In using Halimedinae, Serène (1984) did
not append any discussion, so it is not sure if he also
includes Galene. This family grouping is discussed in
greater detail under the family below.

Ng et al.: Systema Brachyurorum Part I
It now remains to deal with the Pilumninae. In this
treatise, we are regarding this as a separate family, the
Pilumnidae, and we recognise four subfamilies in this new
family grouping: Pilumninae, Rhizopinae, Calmaniinae
and Eumedoninae. Admittedly, this classification is not
ideal - the members are too diverse in form, and
relationships between them are not well understood (e.g.
see Takeda & Miyake, 1968, 1969a). It has been suggested
that the Eumedoninae, previously classified in the
Parthenopidae, are actually pilumnids (Ng & Rodríguez,
1986; Lim & Ng, 1988; Števi & Ng, 1988), an idea first
mooted by Serène (1968) but not followed up by almost
all subsequent workers until the 1980s. Števi et al.
(1988) subsequently recognised the Eumedonidae, as a
separate family, but allied it to the Pilumnidae (cf. Števi
et al., 1988; Mori et al., 1991). In the latest treatment, Ng
& Clark (2000a), using larval and adult morphological
data, argued that eumedonids were only highly derived
pilumnids and treated it only as a subfamily of the
Pilumnidae.

Remarks. – This family contains a number of rather
“atypical” pilumnoids in that they have traditionally been
classified in the Goneplacidae and Xanthidae sensu stricto
Even today, many workers still resist or are very
“uncomfortable” that they are linked to the Pilumnidae. In
general appearance and superficial features, Galene is a
typical “goneplacid”, with its rhomboidal carapace; while
Halimede, Parapanope and Dentoxanthus look like typical
xanthids or panopeids. All are relatively glabrous as
compared to most pilumnids (which are generally setose).
Howver as has been stated many times in this work,
external appearances, especially carapace features, are
extremely deceptive and do not always reflect a taxon’s
phylogenetic history.
The Calmaniini Števi, 1991, is a group of rather unusual
small crabs with just two genera. Their carapace is
somewhat atypical, and their G1s are relatively stouter
than those of more typical pilumnids, although they still
retain their sinuous form. Until more is known,
recognising this group as a full family seems premature,
although it seems reasonable to regard it as a subfamily.
Galene De Haan, 1833, has only one recognised species,
G. bispinosa (Herbst, 1794) (type species) which is widely
distributed in the Indo-West Pacific. Miers (1884)
described Galene granulosa, and this name has been
regarded as valid with doubt. His single specimen was a
juvenile. Chopra (1935) had suggested that Miers'
specimen was only a juvenile of G. bispinosa since all the
specimens of G. granulosa that have ever been collected
were all less than 20 mm in carapace width. Ng et al.
(2001) commented that studies of specimens of different
size groups suggest Chopra (1935) was right in suggesting
that both names are synonyms. Guinot (1969a) provided a
detailed taxonomic history of Galene, detailing the
problems associated with its classification. She proposed
that the genus be placed in a separate grouping - the
"Rameau halimédien", together with the genera Halimede
De Haan, 1825, and Parapanope De Man, 1895, on the
basis of the thoracic sternal structures, general carapace
shape and morphology of the G1s. She considered that
Parapanope and Halimede to be more "xanthien" whereas
Galene tended to be more "catometopien" (using H. Milne
Edwards (1834) terminology for crabs with squarish
appearances). In her later studies, Guinot (1978, 1979)
indicated that Galene was allied with Halimede and
Parapanope in her revised understanding of Pilumnidae.
She however, did not formally transfer these genera into
the Pilumnidae or formally place them in any infrafamilial
grouping. Serène (1984) revived Guinot’s ideas when he
proposed dividing the family Pilumnidae Samouelle,
1819, sensu Guinot, 1978, into several subfamilies - the
Halimedinae being among them. Serène, however, did not
elaborate upon his classification.
Within the Pilumninae sensu stricto, things are far less
clear. It is a huge subfamily with a great diversity of
form and perhaps more subfamilies need to be
recognised. However, the demarcation between groups is
not at all easy. The Bathypilumnini Števi, 2005,
Danielini Števi, 2005, Itampolinae Števi, 2005,
Peleianinae Števi, 2005, and Priapilumnini Števi,
2005, have all been established for single genera whose
members have “atypical” G1s. The Bathypilumnini for
example, have links with some species of Actumnus. We
are not convinced they deserve subfamily status at the
moment, and as we do not use tribes in our system, they
are placed in the synonymy of the Pilumninae sensu
stricto for the moment. The unusual genus
Xenophthalmodes Richters, 1880, for which Števi
(2005) established the subfamily Xenophthalmodinae,
merits comment. Having examined specimens, we feel it
can be recognised as a separate subfamily as it has a
suite of unusual male abdominal and gonopodal features
(see also Ng, 1987).
Ng & Clark (2000b) recently showed that two taxa,
Tanaocheles stenochilus Kropp, 1984 (placed in the
Trapeziidae; see Kropp, 1984), and Chlorodiella bidentata
(Nobili, 1901) (long placed in the Xanthidae; see Serène,
1984) are actually congeneric; and belong to the
Pilumnidae, for which they established a new subfamily,
Tanaochelinae. The tanaochelines are so different that in
the framework of the Pilumnoidea here recognised, it is
reasonable to regard it as a full family.
The ambulatory coxae of Galene are unusual in possessing
distinctly serrated edges, and these are evident even in
small specimens. The presence of serrated coxal plates is a
136

character shared by only one other pilumnoid genus, the
rhizopine Cryptolutea Ward, 1936 (= Serratocoxa Ng,
1987) (see Ng & Davie, 1991). Although the differences
between Cryptolutea and Galene appear substantial, both
genera may well be closely related. Larvae of Cryptolutea
are not known. The larvae of Galene (see Mohan &
Kannupandi, 1986) are pilumnid in every aspect, and are
hardly distinguishable from those of Pilumnus.
Dentoxanthus Stephensen, 1946, belongs to another small
group in the Pilumnoidea. Stephensen (1946) established
Dentoxanthus for a very unusual female specimen of a
new species, D. iranicus, from the Iranian Gulf, and
Tirmizi & Serène (1971) have since reported a second
female from Karachi, Pakistan. The first two males were
described by Tirmizi & Kazmi (1982) from Pakistan.
Stephensen (1946), quoting a personal letter from Balss,
discussed the relationship of Dentoxanthus with
Parapanope, and placed both in the Xanthidae sensu lato.
Serène et al. (1958) reported a suggestion by L. B.
Holthuis (pers. comm.) to refer Dentoxanthus to the
Eumedoninae. Serène et al. (1958) also suggested that
members of the Eumedoninae were closer to the
Xanthidae sensu lato than the Parthenopidae with which it
had traditionally been classified. Števi & Ng (1988)
appraised the taxonomic position of Dentoxanthus
iranicus, and indicated that the taxon was very close to the
Pilumnidae. They suggested establishing a separate tribe
for Dentoxanthus within the Pilumnidae, which was to be
done later. Števi (2005) subsequently established a new
tribe, Dentoxanthini, regardless.
Guinot (1969a) noted that Halimede De Haan, 1825 had
several pilumnid-type characters (in her “Rameau
halimédien”), and she figured the G1 of Halimede
ochtodes, which was slender, long and very straight.
Stephensen (1946) and Campbell & Stephenson (1970)
also figured the G1 of H. ochtodes but not in any detail.
The G2 is sigmoidal and very short. All the male
abdominal segments of H. ochtodes are freely articulating,
and the endophragmal skeleton and sternal structure
conform with what has been defined for the Pilumnidae
(fide Guinot, 1978). The carapace of Halimede is unusual
in that it is very smooth and the margins nodular, and in
many aspects, appears to be intermediate between
Parapanope and Galene. The G1 of Halimede, however,
differs markedly from these two genera, and is closer to
Bathypilumnus. However the carapace of Bathypilumnus,
is typically of the Pilumnus type, with sharp anterolateral
teeth and numerous long, stiff hairs (see Ng & L. W. H.
Tan, 1984b). The larvae of Halimede fragifer were
described by Terada (1985), and they are of the typical
pilumnid type, with short carapace spines. Terada (1985,
1990) allied its larvae together with the pilumnid-type in
his keys, but nevertheless retained the older classification
in which Halimede was left in the Xanthidae sensu stricto.
One species described by Serène (1971) from Indonesia,
Dentoxanthus komodoensis, which was transferred to a
new genus, Otognathon, by Ng & Števi (1993), is more
likely to be a varunid (see Notes under this species in the
Varunidae). Although it has many “xanthoid” type
features and superficially is close to Dentoxanthus and has
long been associated with it, a recent study suggests that
the similarities are merely superficial.
Subfamily Denthoxanthinae Števi, 2005
Parapanope De Man, 1895, is perhaps the most “xanthid”
like of all the members of this group. The appearances are
so strong that Alcock (1898) and other workers have
closely allied Parapanope with Cycloxanthops Rathbun,
1897 (at present in Xanthinae, Xanthidae sensu stricto).
Guinot (1969a, 1985b) had suggested that Parapanope
was apparently closer to the Pilumnidae (in her “Rameau
halimédien”). The form of the endophragmal skeleton,
structure and position of the sternal grooves, presence of
seven freely articulating male abdominal segments, a
slender and sinuous G1, and a sigmoidal G2, clearly allies
Parapanope with the Pilumnidae. The carapace of
Parapanope closely resembles that of Dentoxanthus, with
which Parapanope is probably most closely related. The
male abdomen is similar in shape, as is the G1 of
Dentoxanthus, although in Dentoxanthus, the G1 is
proportionately stouter. The larvae (mentioned in Guinot,
1985b), have clear pilumnid characters, i.e. in the setation
of the various mouthparts and the possession of an
antennal exopod which is as long as the spinous process.
The only unusual feature is the presence of very long
rostral and lateral carapace spines, but these features are
also present on several other pilumnid zoeae, namely
Heteropanope glabra (see Lim et al., 1984) and
Heteropilumnus hirsutior (unpublished data). These
pilumnid larvae are now being described in detail by Paul
Clark as part of his large-scale study of xanthid and
pilumnid larval characters.

Notes
{1} Garthopilumnus Števi, 2005, and Lazaropilumnus
Števi, 2005, are both invalid nomina nuda as they were
erected without diagnostic characters. Števi (2005: 133)
designated Pilumnus palmeri Garth, 1986, as the type
species of Garthopilumnus Števi, 2005, and commented
that it may need to be assigned to its own family
“Garthopilumnidae” – the family name also being
unavailable. The genus should be re-evaluated and
described only when specimens can be examined.
Planopilumnus minabensis Sakai, 1969, was the
designated type species of Lazaropilumnus Števi, 2005.
P. minabensis does require a new genus, and this is part of
an upcoming revision of Planopilumnus Balss, 1933, by P.
K. L. Ng (see point 5). In the case of Balssomedaeus
Števi, 2005, another nomen nuda, there is no problem as
Nanopilumnus Takeda, 1974, and Balssomedaeus Števi,
2005, are objective synonyms because they share the same
type species, Medaeus rouxi Balss, 1936. Takeda (1974)
validly described Nanopilumnus.

{2} Cancer absconditus Herbst, 1783, was briefly
described without figures, and there are no known types
(K. Sakai, 1999). Herbst (1783: 138) compared it with
Cancer occultus Herbst, 1783, which he said was very
close, differing mainly in having short bristles all over its
144

carapace and appendages. We can only guess that this is a
species of Pilumnus or Actumnus.
towards the end of the work which he could not place in
any of his superfamilies, and designated type species for
each. One of these genera was “Lazaropilumnus” for
which the selected type species was Planopilumnus
minabensis Sakai, 1969 (Števi, 2005: 133). However, as
he did not provide any description, diagnosis or indication,
“Lazaropilumnus” is a nomen nudum and not an available
name. In any case, the first author has been revising
Planopilumnus for many years and the manuscript is
almost finished (Ng, in prep.). In this paper, Pilumnus
labyrinthicus Miers, 1884, Pilumnus vermiculatus A.
Milne-Edwards, 1873, Pilumnus penicillatus Gordon,
1931, Planopilumnus minabensis Sakai, 1969, and
Planopilumnus pygmaeus Takeda, 1977, all characterised
by having oval carapaces, three low but visible lobiform
anterolateral teeth, and a labyrinth-like pattern of setae on
their carapace, will be referred to a new genus.
Planopilumnus fuscus Balss, 1933, with its anterolateral
margin armed only with two strong teeth, the carapace
with dense, short wool-like pubescence not arranged in
any patterns, and a very characteristic suborbital margin,
will be referred to its own genus. For the purposes of this
synopsis, we transfer all of them to Pilumnus sensu lato
for the moment. Pilumnus pygmaeus Boone, 1927, is a
senior homonym of Pilumnus pygmaeus (Takeda, 1977)
because of the latter’s temporary transfer from
Planopilumnus. This homonymy will be resolved when
Pilumnus pygmaeus (Takeda, 1977) is referred to a new
genus by P. K. L. Ng (in prep.) and there is thus no reason
to establish a replacement name.
{3} The names Eumedonus, Eumedon and Echinoecus
have a rather confused history because of the way they
have been used. Henri Milne Edwards (1834: 349)
established a new genus, Eumedonus, for one new species,
E. niger, from China (H. Milne Edwards, 1834: 350) (see
also H. Milne Edwards, 1837: plate 15: figure 7). In H.
Milne Edwards' (1834) descriptions, he always provided a
vernacular name before the scientific name for each genus
and species, and for Eumedonus, he introduced the genus
as “Eumedon Eumedonus” (H. Milne Edwards: 349).
Subsequently, Alphonse Milne-Edwards (1879) described
a species he named as Eumedon pentagonus from
Mauritius. The use of the spelling of the genus name
‘Eumedon’ by A. Milne-Edwards (1879), however, should
not be regarded as the establishment of a new genus.
Alphonse Milne-Edwards (1879) quite obviously
incorrectly used the spelling 'Eumedon' in place of
‘Eumedonus’, because in this paper, whenever he
established a new genus (e.g. Goniothorax and
Rhabdonotus), he made sure that it was introduced as such
(i.e. adding the suffix ‘nov. gen.’) and provided a diagnosis
for each. But in the case of “Eumedon pentagonus”, he
introduced the species as new (as a ‘nov. sp.’) but without
any comments on the genus. The use of the spelling
‘Eumedon’ by A. Milne-Edwards (1879) should thus be
regarded as an incorrect spelling of Eumedonus (see Chia
& Ng, 2000). Rathbun (1894b) was the first to establish a
new name, Echinoecus, for A. Milne-Edwards (1869)
species, i.e. Echinoecus pentagonus (A. Milne-Edwards,
1869). Many workers (e.g. Laurie, 1915; Balss, 1922a),
however, continued to use the generic name Eumedonus,
apparently accepting that A. Milne-Edwards (1869) had
merely used an incorrect spelling. Ward (1934) was the
first to follow Rathbun (1894) in regarding Echinoecus as a
distinct genus from Eumedonus sensu stricto, differentiated
by the form of the carapace, angle of the antennule, and
structures of the eye and G1. This has been followed by
most subsequent authors (e.g. Miyake, 1939; Serène et al.,
1958) (see Chia et al., 1999, for review).
{6} Cancer incanus Forskål, 1775, was only briefly
diagnosed, and the name has not been used subsequently.
However, it seems likely that what is known at present as
Pilumnus incanus Klunzinger, 1913, from the Red Sea,
was actually based on Forskål’s (1775) name. Certainly
their descriptions match well. The latter name, however, is
generally regarded as a junior synonym of Pilumnus
forskalii H. Milne Edwards, 1834. As this species has
rarely been reported, we apply the Principle of Priority in
synonymising Pilumnus forskalii H. Milne Edwards, 1834,
with Cancer incanus Forskål, 1775, having clear priority.
{7} Parapilumnus euryfrons Garth & Kim, 1983, is
actually a junior synonym of Pilumnus neglectus Balss,
1933. One of the authors (P. K. L. Ng) has examined types
of both species, and they are clearly conspecific (see also
Ng, 2002a).
{4} Pilumnus lacteus A. Milne-Edwards, 1880, is a
subjective junior synonym of Pilumnus floridanus
Stimpson, 1871, which is also a junior homonym of
Pilumnus lacteus Stimpson, 1871. As such, there is no
nomenclatural problem at the moment. But if Pilumnus
lacteus A. Milne-Edwards, 1880, was to be later shown to
be a distinct species, a replacement name will be needed.
{8} P. J. F. Davie is currently revising the composition of
Lophoplax Tesch, 1918, and some of its members will
need to be separated into a distinct genus.
{5} As has been discussed earlier under the family
Planopilumnidae, if Planopilumnus (here restricted to P.
spongiosus and P. orientalis) is a pseudoziid, the rest of
the species which have been placed in Planopilumnus by
many authors need to reappraised. The problem is that of
the remaining six species of “Planopilumnus”,
Planopilumnus fuscus Balss, 1933, is also quite different
from the rest. In his synopsis of the Brachyura, Števi
(2005) appended a list of new genera he recognised
{9} Cancer semicylindrus Fabricius, 1798, has been
referred to various genera and families, but P. K. L. Ng
has examined a syntype specimen in the Copenhagen
Museum, and it is clearly a member of the genus
Xenophthalmodes. It may be a senior synonym of a better
known species, but until the genus is revised, it is here
regarded as a distinct species.

Notes
{1} The nomenclatural situation with Carcinus and its
type species, Cancer maenas Linnaeus, 1758, was
clarified in Opinion 330 (ICZN, 1955).
{2} Libystes villosus Rathbun, 1924, was described from a
single female from Samoa, with Edmondson (1951)
recording it from Hawaii. Stephenson (1972) synonymised
L. villosus with L. nitidus A. Milne-Edwards, 1867 (type
locality Zanzibar), and this has been followed by most
subsequent workers (e.g. Vannini & Innocenti, 2000).
Apel & Spiridonov (1998: 176) discussed the taxonomy of
Libystes nitidus in detail and indicates that in lieu of a
revision of the genus, most of the existing synonymies of
species are questionable. In the case of L. villosus, Apel &
Spiridonov (1998: 179) commented that the G1 of the
Hawaiian male figured by Edmondson (1951) differed
markedly from the specimens of L. nitidus from the
Arabian Gulf and Red Sea, suggesting that they are not
congeneric. Consequently, Apel & Spiridonov (1998: 176)
placed L. villosus in the synonymy of L. nitidus with
doubt. The types and preferably topotypic material of L.
nitidus and L. villosus will need to be re-examined. As
such, we prefer to recognise both as separate species.
{3} When Stimpson (1871) established Bathynectes, he
named two species, B. longispina and B. brevispina, but
did not specifically designate a type species. Fowler
(1912) was the first to formally designate B. longispina as
the type species. The ICZN subsequently ratified this in
Opinion 73, Direction 37. However, one may argue that
Stimpson (1871) himself had selected B. longispina as the
type species. In his comments on the second species, B.
brevispina, he wrote: “This species greatly resembles the
typical form in color and other characters …” (Stimpson,
1871: 147). His use of the word “typical” can be construed
to mean that he recognised B. longispina as the type
species, although Article 67.5.2 of the Code expressly
states that this is not acceptable.

There is also a problem with B. brevispina Stimpson,
1871. Although Stimpson argued that it was
morphologically very close to B. longispina, the fact is
that B. longispina was described from the Straits of
Florida in the Gulf of Mexico (Atlantic), whereas B.
brevispina was from the Marquesas in the Pacific. It is
difficult to believe that both are conspecific (e.g. see
Tavares, 2003), or even congeneric, unless the original
labels are wrong. Certainly, the only specimen of B.
brevispina, a large female, needs to be re-examined.
{4} The taxonomy of Polybius and its allies was
reappraised by d’Udekem d'Acoz (1999: 218–224) who
proposed a somewhat radical classification. Without much
discussion, he placed the polybiine genera Liocarcinus,
Macropipus and Necora under the synonymy of Polybius,
and as well, transferred into it a species of Xaiva (from the
subfamily Carcininae). He, however, recognised Polybius,
Macropipus and Necora as subgenera of Polybius. He also

Ng et al.: Systema Brachyurorum Part I
recognised an unnamed “sous-genre nouveau” (under
Polybius) in his compilation (p. 222) in which he includes
three species: Portunus maculatus Risso, 1827 (now in
Liocarcinus), Portunus pusillus Leach, 1815 (now in
Liocarcinus), and Portumnus mcleayi Barnard, 1947 (now
in Xaiva). It is difficult to accept his actions, at least on the
basis of what was stated. The various genera as they have
been recognised, are all relatively distinct, and we revert
to the older system for now. Similarly Portunus bolivari
Zarquiey Alvarez, 1948, which was transferred to
Polybius by d’Udekem d'Acoz (1999) should be retained
in Liocarcinus as is currently accepted by most authors (L.
B. Holthuis, in litt.. 7 June 2007). That being said, genera
like Liocarcinus and Macropipus probably require a
revision. The subfamilial system now utilised for the
Portunidae also seems rather artificial, and some like the
Polybiinae especially, need reappraisal.
Praecedentibus affinis at minor. Thorax holosericeus,
parum inaequalis, hine inde scaber. Chelae sanguineo
maculatae digitis apice dentibusque albis.” These differing
descriptions strongly suggest Fabricius intended them to
refer to two different species, especially as the 1793 name
was for Australian material, and the later 1798 specimens
were from “Oceano Asiatico Dom. Daldorff” (=
Tranquebar, India), and the earlier Australian record was
not mentioned. It is significant that of the 22 species
Fabricius (1798) treated in Portunus, he credited puber,
depurator, feriatus, pelagicus, hastatus to Linnaeus;
sanguinolentus to Herbst; and cross-refered holosericus,
lancifer, defensor, armiger and forceps to his 1793 paper.
He did not, however, make any cross-reference to vigil,
crucifer, lucifer, annulatus, variegatus, truncatus, holsatus,
tranquebaricus, gladiator, hastatoides and ponticus. As
such, these names should be treated as new. Zimsen’s
(1964) catalogue of Fabricius’ types also lists the two
names separately. Under Cancer gladiator Fabricius, 1793,
Zimsen (1964: 648) noted that the types are lost, but under
Portunus gladiator Fabricius, 1798, four type specimens
are recorded (Zimsen, 1964: 651). This has been confirmed
following the examination of these specimens by P. K. L.
Ng. Stephenson & Cook (1973) agreed with Latreille
(1825) that Cancer gladiator Fabricius, 1793, should be a
junior subjective synonym of Portunus (Portunus)
sanguinolentus (Herbst, 1783), and because the types of
Cancer gladiator Fabricius, 1793, are lost, they designated
a specimen of P. sanguinolentus as the neotype for C.
gladiator Fabricius, 1793, to ensure this synonymy.
{5} Cancer pellitus Forskål, 1775, is a name not used
since its original description. P. K. L. Ng has examined
the original description with L. B. Holthuis, and we are
sure that it is conspecific with Liocarcinus corrugatus
(Pennant, 1777) (unpublished data). We here invoke
Article 23.9.2 of the Code to conserve the better known
name.
{6} The identities of Portunus guadulpensis Saussure,
1858, and Ovalipes ocellatus floridanus Hay & Shore,
1918, were substantially clarified by Türkay (1971) when
he redescribed and figured their types. It leaves no doubt
that Saussure’s species is not a species of Ovalipes as had
been presumd by some authors but belonging to
Macropipus instead. Williams (1976) agreed, and
elaborated on the taxonomy of the American species of
Ovalipes.
Miers (1886) designated Portunus gladiator Fabricius,
1798, as the type species for Portunus (Amphitrite) De
Haan, 1833. However, Gistel (1848) had earlier provided a
replacement name, Monomia, because the subgeneric name
Amphitrite De Haan, 1833, is pre-occupied by a polychaete
genus, Amphitrite Mueller, 1771. The type species for
Portunus (Monomia) Gistel, 1848, remains as Portunus
gladiator Fabricius, 1798. Cancer gladiator Fabricius,
1793, is by contrast, now a member of Portunus
(Portunus), but as a junior synonym of Portunus
sanguinolentus (Herbst, 1783).
{7} Using molecular and morphological data, Mantelatto
et al. (2007) recently synonymised Portunus bahamensis
Rathbun, 1930, with Portunus depressifrons (Stimpson,
1859) ; and Portunus vossi Lemaitre, 1991, with Portunus
spinimanus Latreille, 1819.
{8} The identities of the two names, Cancer gladiator
Fabricius, 1793, and Portunus gladiator Fabricius, 1798, is
interesting. Stephenson & Cook (1973) regarded Cancer
gladiator Fabricius, 1793, as a separate taxon from
Portunus gladiator Fabricius, 1798. Davie (2002)
commented that perhaps Fabricius had simply
misidentified the later material, and that the 1798 name
could be simply treated as a secondary synonym rather
than being intended as a new taxon. However, as we
explain further here, this now seems unlikely. Fabricius
(1793: 449) described Cancer gladiator as: “gladiator. 35.
C. thorace laevi: lateribus octodentatis, postico maximo,
minibus angulatis. Cancer hastatus. Mant. Ins. I. 319.34.
Habitat in nova Hollandia Mus. Dom. Banks. Minutus
nullo modo Cancer hastatus Linnaei. Palmae anticae
bidentatae, chelae angulatae. Palmae posticae ovatae.”.
However, later Fabricius (1798: 368) described Portunus
gladiator as: “gladiator. 19. P. thorace tomentoso utrinque
novemdentato: dente postico maiore, minibus sanguineo
maculates. Habitat in Oceano Asiatico Dom. Daldorff.
The four syntypes of Portunus gladiator Fabricius, 1798,
in the Zoological Museum of the University of
Copenhagen are from Tranquebar in southern India, and
conform with how the species is defined by Stephenson
& Cook (1973) under the name of Portunus haani
Stimpson, 1858. Stephenson & Cook (1973) commented
that as Cancer gladiator Fabricius, 1793 (= Portunus
sanguinolentus (Herbst, 1783)), is now in the same
genus as Portunus gladiator Fabricius, 1798, then the
two Fabricius names are secondary homonyms. That
they are in separate subgenera does not affect the
nomenclatural rules pertaining to secondary homonymy.
Stephenson & Cook (1973) further argued that as
Portunus gladiator Fabricius, 1798, is the junior
homonym, it cannot be used, and must be replaced by
the next available name, Amphitrite haanii Stimpson,
1858. This is the name now used by most workers (e.g.
see Davie, 2002). However, as Cancer gladiator
Fabricius, 1793, is regarded as a junior synonym of
156
THE RAFFLES BULLETIN OF ZOOLOGY 2008
Portunus sanguinolentus (Herbst, 1783), the name
“Portunus gladiator (Fabricius, 1793)” has not been
recognised or used anywhere. This being the case, there
is no homonymy with Portunus gladiator Fabricius,
1798, and this name should remain available for use
under the Code. The issue of secondary homonymy will
only arise if Cancer gladiator Fabricius, 1793, is
regarded as a valid species of Portunus distinct from
Portunus sanguinolentus (Herbst, 1783). If this were to
happen (for example if the widespread P. sanguinolentus
was to prove to be a complex of several cryptic species),
then the name Portunus gladiator Fabricius, 1798, would
have to be replaced by the next available name, Portunus
haanii (Stimpson, 1858).
133), and Portunus integifrons Marion de Procé, 1822 (p.
134) require comment. Both names have not been used
since they were described from Manila in the Philippines.
As far as we know, there is no type material remaining.
From the description, we are confident P. denticulatus
Marion de Procé, 1822, is synonymous with Portunus
pelagicus (Linnaeus, 1758). The description of Portunus
integifrons Marion de Procé, 1822, agrees well with a
common reef species, Thalamita admete (Herbst, 1803),
and in the absence of specimens, we synonymise the two
names with doubt.
{14} On the basis of the description provided of
Portunus tropicalis by Marion de Procé (1822: 133)
(from among sargassum beds near the Azores), we have
little doubt that it is the same as the well known
sargassum swimming crab Portunus sayi (Gibbes, 1850).
While P. tropicalis has priority, the name itself has not
been used since it was described, and it would serve no
purpose to have it replaced. Following Article 23.9.1.1 of
the Code, Lupa sayi Gibbes, 1850 (at present in
Portunus) is given priority over Portunus tropicalis
Marion de Procé, 1822, as they are regarded as
synonyms. The name Lupa sayi Gibbes, 1850, is
therefore a nomen protectum, while Portunus tropicalis
Marion de Procé, 1822, is here regarded as a nomen
oblitum. Marion de Procé’s material does not appear to
be extant, though it seems at least some of his material
arrived back in France. For example, his specimens of
one species of fiddler crab (Ocypodidae) were passed to
Desmarest (1823) who described (p. 243) it as a new
species, Gelasimus marionis. In naming this crab,
Desmarest noted (in French) (as Gélasime de Marion):
"Cette espèce... est de Manille. Elle m'a été
communiquée par M. Marion de Procé de Nantes, à qui
je la dédie" (see also Desmarest, 1825: 125). Gelasimus
marionis Desmarest, 1823, is currently a junior synonym
of Uca vocans (Linnaeus, 1758). The Paris Museum does
not have any of Marion de Procé’s material.
{9} Amphitrite argentata White, 1847, is a nomen nudum,
and is not an available name (see also Clark & Presswell,
2001). The name “argentatus” was first made available by
A. Milne-Edwards (1861: 332, pl. 31 fig. 4) who
published a description and figure of it under the name
Neptunus argentatus (see Davie, 2002). He based this on
White’s (1847) material in the Brtish Museum (Natural
History) in London (present Natural History Museum),
and this is possibly the reason why many carcinologists
still incorrectly attribute the name to White.
{10} Portunus ponticus Fabricius, 1798, was described
from Indian Seas, and the types (two specimens) are in the
Zoological Museum of the University of Copenhagen
(Zimsen, 1964: 652). P. K. L. Ng examined the specimens
and it is similar to P. gladiator in many respects, and as
such, is referred to the subgenus Portunus (Monomia) for
the moment.
{11} The selection of a type species for the commercially
important genus Portunus Weber, 1795, has been
discussed in detail by Holthuis (1952).
{12} It has become clear for some time that what is now
called Portunus pelagicus is actually a complex of four
cryptic species. Ongoing studies by Joelle C. Y. Lai, P. K.
L. Ng and P. J. F. Davie using morphological,
morphometric and molecular characters have shown that
four species can in fact be recognised (unpublished data),
for which the names Portunus pelagicus (Linnaeus, 1758),
P. reticulatus (Herbst, 1799), P. segnis (Forskål, 1775)
and P. armatus (A. Milne-Edwards, 1861), will be used
Lai et al., in prep.). A few clarifications are necessary. The
true identity of Cancer segnis Forskål, 1775, has never
been established, and the name has always been regarded
as a nomen dubium. Nevertheless, on the basis of
Forskål’s description, albeit rather brief, there is little
doubt in our opinion that it is close to Portunus pelagicus
sensu stricto, and we now reuse this name for one of the
cryptic species we recognise from the Indian Ocean. We
use one of Herbst’s names, Cancer reticulatus Herbst,
1799, for the second Indian Ocean species. The name of
the Australian species is Portunus armatus (A. MilneEdwards, 1861), a name which has been missed by most
brachyuran workers, including Stephenson (1972).
{15} Many authors follow Stephenson (1972) in using
Portunus (Hellenus) A. Milne-Edwards, 1874, as the name
for this subgenus, but Xiphonectes A. Milne-Edwards,
1873, has priority since both their type species are
currently regarded as congeneric.
{16} Portunus pseudohastatoides Yang & Tang, 2006,
was described without assignment to a subgenus. On the
basis of their description and the very close affinities their
species has with P. hastatoides, it is clear that it should be
referred to the subgenus Portunus (Xiphonectes).
{17} The identity of Cancer menestho Herbst, 1803, is
problematic. Latreille (1825) suggests that Cancer
menestho may be a synonym of Portunus gladiator but
Stephenson & Cook (1973) indicate that it was more likely
to be affiliated with P. rubromarginatus (Lanchester,
1900).
{18} Amphitrite media Stimpson, 1858, is a problem.
Some authors regard this as a junior synonym of P.
gladiator (e.g. Alcock, 1899) but Stephenson & Cook
{13} Portunus denticulatus Marion de Procé, 1822 (p.
157
Ng et al.: Systema Brachyurorum Part I
(1973) suggest that it was closest to Portunus orbitosinus
Rathbun, 1911, and may even be synonyms. The absence
of types means that the matter may need to be resolved
with the judicious selection of a neotype of Amphitrite
media Stimpson, 1858, from Hong Kong.
Alain Crosnier (pers. comm.) feels that it is better to retain
T. gracilipes in Thalamita for the moment.
{19} The identities of Cancer defensor Fabricius, 1787,
and Cancer armiger Fabricius, 1787, are uncertain. The
types of C. defensor and C. armiger are lost (Zimsen,
1964: 647) and is problematic. Both were described from
Australia, and on the basis of the original descriptions, are
likely to be species of Portunus. These two were among
four species of poorly known portunids (the other two
being C. lancifer and C. holosericus) described by
Fabricius (1787) for which the types are no longer extant.
Fabricius (1793) later treated all four species but did not
cross-refer them to his 1787 paper (see points 8, 21, 28).
{27} The name Portunus affinis Weber, 1795, was based
on information from Daldorff, and it is likely that it may
be based on a species from southern India (see discussion
of Weber versus Fabricius in Introduction). There are no
types, so its identity cannot be determined.
{26} Crosnier (2002) recently synonymised Thalamita
wakensis Edmondson, 1925, with T. seurati Nobili, 1906.
{28} Cancer lancifer Fabricius, 1787, was described from
somewhere in the Pacific, and from the original
description, is likely to be a species of Thalamita. The lack
of types (Zimsen, 1964: 647) makes its identity impossible
to ascertain.
{20} Shen (1934) named Charybdis gordoni for Isabella
Gordon, a woman, so the ending must be amended to
“gordonae”.
{21} The types of Cancer holosericus Fabricius, 1787, are
lost (Zimsen, 1964: 647). Fabricius (1787: 326) described
the species from Australia, but later (Fabricius, 1798: 365,
as Portunus holosericus) reported more specimens from
Indian Seas. This Indian Ocean material (four specimens,
not types), is still in the Zoological Museum of the
University of Copenhagen (Zimsen, 1964: 648). P. K. L.
Ng has examined them and it closely resembles Charybdis
(Charybdis) granulata (De Haan, 1833), and may be
conspecific. It is here referred to the subgenus Charybdis.
Fig. 115. Benthochascon hemingi, central Philippines (photo: T. Y. Chan)
{22} In a recent study, Türkay & Spiridonov (2006)
recognised two subspecies in Charybdis (Goniohellenus)
omanensis Leene, 1938; the nominal subspecies, and a
new one from the western Indian Ocean, C. (G.)
omanensis septentrionalis.
{23} The gender of Gonioinfradens Leene, 1938, should
be masculine, as the gender of “dens” (or tooth) is
masculine.
{24} Naruse & Shokita (2003), in reporting a second
specimen of T. cerasma Wee & Ng, 1995, from Japan (cf.
Takeda & Marumura, 1997), argued that the differences
given by Crosnier & Moosa (2002) to separate T. cerasma
rectifrons from T. cerasma cerasma are slight, and likely
to be due to variation. Although they deferred
synonymising both names, we concur with their
observations and regard the two taxa as synonymous.
Fig. 116. Libystes cf. villosus, central Philippines (photo: T. Y. Chan)
{25} Crosnier (1978) placed Thalamita gracilipes (A.
Milne-Edwards, 1873) in Thalamonyx A. Milne-Edwards,
1873 (type species Thalamita danae Stimpson, 1858), the
genus in which it was originally described. However, T.
danae is now considered to belong to Thalamita, thus if T.
gracilipes is considered generically distinct from T. danae,
then it must be referred to its own as yet unnamed genus.

Remarks. – The taxonomic situation with the family
Potamidae is difficult due to its large number of species.
Bott (1970) had recognised four separate families in his
Potamoidea: Potamidae Ortmann, 1896, Potamonautidae
Bott, 1970, Sinopotamidae Bott, 1970, and Isolapotamidae
Bott, 1970; all of which had discrete distributions.
Members of the Potamonautidae were African (south of
the Sahara), members of the Sinopotamidae primarily
Chinese, while those of the Isolapotamidae were mainly
Southeast Asian with some East Asian representatives
(Bott, 1970). The rest of the Asia was occupied by
Potamidae species. Ng (1988) synonymised the
Sinopotamidae and Isolapotamidae with the Potamidae,
commenting that there were no good characters except
perhaps distribution (see also Ng & Tan, 1998;
Cumberlidge, 1999; Dai, 1999; Yeo & Ng, 1999, 2003;
Yeo et al., 2008). Brandis (2002), however, using mainly
the detailed structure of the G2, argued that both
Sinopotamidae and Isolapotamidae were valid families,
although he slightly rearranged the Bott’s (1970) generic
composition. On the basis of the G2 structure, he also
noted that some genera should be synonymised. A recent
detailed DNA analysis of a large number of potamid
genera (sensu Ng, 1988) by Shih et al. (in prep.) found no
support for the Sinopotamidae, only weak resolution
(though not at the family level) for a clade corresponding
to Brandis’ (2002) “Isolapotamidae” (though not with the
same generic composition), and that most of the genera
currently recognised were genetically distant. It thus
seems best to recognise one Asian family for the
Potamoidea, Potamidae.

{4} The relatively well known freshwater crab, Potamon
setiger Rathbun, 1904, should have its specific name
corrected to “setigerum”. The word “setiger” is an
adjective ( meaning bristles), and as the gender of
Potamon is neuter, it should be “setigerum”.
{5} The name “Cancer (Thelphusa) berardii De Haan,
1835”, is sometimes cited as a junior synonym of
Thelphusa dehaani White, 1847, currently Geothelphusa),
but this is incorrect. It is not a new name but an incorrect
usage of Audouin's (1826) name "Thelphusa berardi".
Thelphusa berardi Audouin, 1826, is a valid species of
Potamonautes MacLeay, 1838 (Potamonautidae).

Notes
{1} In a preliminary reappraisal of the 91 species which
have been placed in or allied to Potamon sensu lato from
Indochina, parts of India and China at one time or another,
Yeo & Ng (2007) assigned them to various recognised as
well as many new genera.

{2} In describing Potamon (Himalayapotamon)
atkinsonianum gordoni, Pretzmann (1966: 5) stated that it
was dedicated to “Frau Dr. Isabella GORDON gewidmet”.
And as such, the name should be corrected to “gordonae”.
In any case, at the moment, Pretzmann’s species is
regarded as a subjective junior synonym of
Himalayapotamon emphyseteum (Alcock, 1909).
{3} Bouvier (1917) established Lobothelphusa as a
subgenus of Hydrothelphusa, commenting that the Asian
species that Alcock (1900, 1910a, b) had classified in
Acanthothelphusa Ortmann, 1897, did not belong there as
there were a number of distinct morphological differences.
As the name was accompanied by a clear indication to
Alcock as well as stated the characters he felt were
diagnostic, Lobothelphusa Bouvier, 1917, is an available
name, although no type species was designated. The Asian
species treated by Alcock were: Potamon (Paratelphusula)
calvum Alcock, 1909, Paratelphusa crenulifera WoodMason, 1875, Potamon (Acanthotelphusa) crenuliferum
floccosum Alcock, 1910, Telphusa (Paratelphusa) dayana
Wood-Mason, 1871, Paratelphusa feae De Man, 1898,
Potamon (Paratelphusa) fungosum Alcock, 1909,
Paratelphusa martensi Wood-Mason, 1875, and Potamon
(Parathelphusa) woodmasoni Rathbun, 1905. The first valid
designation of a type species was Bott (1970: 146) who
selected Paratelphusa crenulifera Wood-Mason, 1875, as
the type species (see also Yeo & Ng, 2007).

Remarks. – Cumberlidge et al. (2008) did a substantial
reappraisal of the classification of the Potamonautidae, and
that is followed here (see also Daniels et al., 2006). The
synonymisations of the Deckeniidae and Globonautinae
(previously in the Gecarcinucidae) in the Hydrothelphusinae, and the Platytelphusidae with the Potamonautinae, are
radical. While their revision makes the distributional
patterns of the crabs far more parsimonious, the
classification challenges several important characters
previously used to define freshwater crabs. Key among
these is the value of the structure of the mandibular palp. It
is consistently bilobed in both the Pseudothelphusoidea and
Gecarcinucoidea, but in their redefined Potamonautidae, the
condition varies. A group in West Africa, the Globonautinae, traditionally linked with the gecarcinucoids was
referred to the Potamonautidae for the first time, based on
morphological and DNA datasets. Interestingly, the G1 of
“globonautines” is typically like most potamonautids and
potamoids, with two well demarcated segments. Most
gecarcinucoids on the other hand (but not all), have simple
undifferentiated G1s. Their revised system also synonymises the Deckeniidae with the Hydrothelphusinae despite the
fact that Deckenia is a highly apomorphic. It may be better
to recognise Deckenia and Seychellum as a separate
subfamily in the Potamonautidae. Števi (2005) established a new subfamily, Seychellinae Števi, 2005, in his
Potamidae sensu lato, taking into account the characters
discussed in Ng et al. (1995) when the genus Seychellum
was first established. However, the characters of this genus
are very apomorphic, and placing it in its own subfamily is
unnecessary in view of the unreliability of the mandibular
palp structure in African taxa. The system of Cumberlidge
et al. (2008), while unorthodox, still appears to be the best
proposal thus far (see also Yeo et al., 2008). Their overall
datasets, notably the molecular ones, are convincing.

Notes
{1} These names have been synonymised under different
taxa by workers, but have been recognised as valid by Neil
Cumberlidge (pers. comm.) as part of his unpublished
studies (see also Cumberlidge et al., 2008).
{2} The proper spelling of the species name is Thelphusa
berardi and not T. berardii. The first edition (1826) of
Audouin gives the spelling "berardi", which is modified to
"Berardii" in the second edition (1827). The first spelling
has priority (see Guinot & Cleva, 2008).

Notes
{1} The authorship for this species should be “Lucas, in
H. Milne Edwards & Lucas, 1844”, rather than just “H.
Milne Edwards & Lucas, 1843” (Guinot & Cleva, 2002).
{2} In naming Hypolobocera rathbuni, Pretzmann (1968:
6) noted that it was “In memoriam Mary J. Rathbun”. As

to
{3} Most modern workers regard Gordonia Pretzmann,
1965,
and
Isabellagordonia
(Isabellagordonia)
Pretzmann, 1965, as possible synonyms of Phrygiopilus
Smalley, 1970 (see Rodríguez, 1982), but keep using the
latter name even though it is junior to both of Pretzmann’s
names. If these taxa are indeed synonymous, then
Phrygiopilus Smalley, 1970, will need to be replaced with
one of Pretzmann’s names.

THE RAFFLES BULLETIN OF ZOOLOGY 2008
FAMILY PILUMNOIDIDAE GUINOT &
MACPHERSON, 1987
SUPERFAMILY PSEUDOZIOIDEA
ALCOCK, 1898
Remarks. – This superfamily is recognised because its
members possess a suite of characters that preclude their
classification elsewhere. There have been numerous
conflicting views over the relationships of its included
families, and thus its monotypy will need further testing.
Members of this superfamily have at one time or another
been classified with the present Carpilioidea, Xanthoidea,
Pilumnoidea or Goneplacoidea (see Alcock, 1898; Serène,
1984; Ng & Wang, 1994; Ng & Liao, 2002; Ng, 2003b;
Ng et al., 2001). Ng & Wang resurrected the Pseudozioida
Alcock, 1898, as a subfamily but referred it to the
Goneplacidae. Ng & Liao (2002) later recognised it as a
distinct family and included the genera Euryozius Miers,

Notes
Števi (2005) was the first to recognise the superfamily
Pseudozioidea with two families, Pseudoziidae and
Flindersoplacidae Števi, 2005, each with only its type
genus. Euryozius was not treated. In his Goneplacoidea, he
recognised the Planopilumnidae Serène, 1984, as a distinct
family; and placed Platychelonion in its own tribe,
Platycheloniini Števi, 2005, in the subfamily
Geryoninae, (Geryonidae). As is typical of this work, no
discussion or justification was provided. We do not agree
with the need for a separate family for Flindersoplax; its
affinities with Pseudozius are clear (Davie, 1989; Ng &
Liao, 2002). The arguments for placing the genera
Planopilumnus and Platychelonion together, close to
Pseudozius, have also been summarised by Ng & Liao
(2002) and Ng (2003b). It makes no sense to classify
Planopilumnus and Platychelonion in separate families;
and in a distinct superfamily from Pseudozius.
{1} The authorship of this genus should be “Lucas, in H.
Milne Edwards & Lucas, 1844”, rather than just “H. Milne
Edwards & Lucas, 1843” (Guinot & Cleva, 2002).
FAMILY PLANOPILUMNIDAE SERÈNE, 1984
Planopilumninae Serène, 1984
Platycheloniini Števi, 2005
Remarks. – Planopilumnus Balss, 1933, was originally
established for five species, Pilumnus spongiosus Nobili,
1905 (designated type species), Planopilumnus orientalis
Balss, 1933, Planopilumnus fuscus Balss, 1933,
Pilumnus vermiculatus A. Milne-Edwards, 1873, and
Pilumnus labyrinthicus Miers, 1884. At the same time,
Ward (1933) established a new genus, Rathbunaria, for a
new species, Rathbunaria sculptissima from Australia.
Balss (1938b) commented that his (1933) paper preceded
Ward’s (1933) publication by two months. This is
difficult to verify. While Ward's paper had a date of
publication, Balss’ did not, and we will have to take
Balss at his word that this is correct, and Planopilumnus
is the older name. Balss (1938) also synonymised
Rathbunaria
sculptissima
Ward,
1933,
with
Planopilumnus orientalis Balss, 1933.
Karawasa & Schweitzer (2006) disagreed with Števi
(2005) that a superfamily for Pseudoziidae was necessary
and instead classified it in their Eriphioidea. While we
agree that the Pseudoziidae may be related to the
Eriphioidea, they do possess several characters (notably
their characteristic G1 and G2 structures), and therefore
should be separated.
With regards to the unusual genus Pilumnoides Lucas, in
H. Milne Edwards & Lucas, 1844, Guinot & Macpherson
(1987) established the subfamily Pilumnoidinae for it but
without assigning it to any particular family. Several
subsequent authors have treated it as a distinct family (e.g.
Türkay, 2001; Števi, 2005; Karawasa & Schweitzer,
2006). Števi (2005) classified it in the Eriphioidea, but
Karawasa & Schweitzer (2006) recognised a superfamily
Pilumnoidoidea for it. While the carapace features of this
genus are unusual, its male abdominal and gonopodal
characters are similar to other pseudozioids and we prefer
to place it there.
In proposing a revised classification of the Pilumnidae,
Serène (1984) five subfamilies: Pilumninae Samouelle,
1819, Halimedinae Alcock, 1898, Heteropanopeinae
Alcock, 1898, and two new subfamilies, Planopilumninae
and Heteropilumninae. This, however, was done in a
footnote. Serène (1984) included these subfamilies in his
key to the Xanthoidea but did not elaborate on them. The
problem here is that neither P. spongiosus nor P. orientalis
are pilumnids as understood at present. Their G1s are
relatively stout and straight, and the distal parts are lined
179
Ng et al.: Systema Brachyurorum Part I
with numerous short, stout spines, with the G2 basal
segments distinctly longer. Ng & Clark (2000a, b) have
commented on this and indicated that the Planopilumninae
must be excluded from the Pilumnidae. Ng et al. (2001:
33) subsequently commented that with “… regards to the
Planopilumninae, the type species of the type genus,
Planopilumnus spongiosus (Nobili, 1905), is actually not a
pilumnid at all but closer to goneplacids like the
Pseudoziinae instead. The genus Planopilumnus as
currently understood, is heterogeneous.” Davie (2002)
most recently commented that “The type-species of
Planopilumnus, P. spongiosus (Nobili, 1905) is clearly not
a pilumnid at all, because of the very different form of the
gonopods, and therefore the Planopilumninae is tentatively
recognised but removed to the Goneplacidae, with its
closest relatives probably with the Pseudoziinae genera.
Planopilumnus labyrinthicus (Miers, 1884) is however a
typical pilumnid, and is here treated as a Pilumnus species
until a new genus is described to receive it (P.K.L. Ng in
prep.).” Števi (2005) recognised the family
Planopilumnidae in his Goneplacoidea, but Ng & ManuelSantos (2007) disagreed and referred it back to the
Pseudoziidae (see also Ng, 2003b; Ng & Liao, 2002).

Remarks. – The genus Thia Leach, 1815, and family Thiidae
Dana, 1852, have long been associated with the
Atelecyclidae Ortmann, 1893, but recent studies suggest that
it may not be a member of that family, or even of the
superfamily Cancroidea. Major changes are about to take
place with genera previously assigned to the Atelecyclidae
(Cleva & Tavares, in prep.; Guinot et al., 2008).
Interestingly, recent molecular studies suggest that the
Thiidae should be aligned with members of the Portunoidea
(C. D. Schubart, unpublished data) and should eventually be
transferred there. For the moment, and we tentatively refer it
to its own superfamily.

stout G1, and short G2. These characters mean that its
traditional placement in the Corystidae is untenable, despite
their superficially similar carapace shapes, and somewhat
setose antennae.

THE RAFFLES BULLETIN OF ZOOLOGY 2008
interesting is that that all tetraliids of both sexes exhibit
extreme heterochely, with one of the chelipeds greatly
enlarged compared to the other. In contrast, heterochely in
trapeziids is less pronounced. However, we concur with
Schweitzer (2005) in that some of the trapeziid genera
(like Calocarcinus and allies) might belong elsewhere (see
below).
SUPERFAMILY TRAPEZIOIDEA
MIERS, 1886
Remarks. – Števi (2005: 39) used Trapezioidea for the
first time and recognised just one family, Trapeziidae,
with three subfamilies, Domeciinae, Tetraliinae and
Trapeziinae. Karasawa & Schweitzer (2006) disagreed and
placed the Trapeziidae sensu lato in the Xanthoidea. In
this synopsis, we have recognised a superfamily as Števi
(2005) did , but with three distinct families, Trapeziidae,
Tetraliidae and Domeciidae.
With the reclassification of the traditional Trapeziidae by
Castro et al. (1994), it seems useful to also recognise
subfamilies within the Trapeziidae sensu stricto Števi
(2005) recognised three tribes in his Trapeziidae,
Calocarcinini Števi, 2005, Quadrellini Števi, 2005,
and Sphaenomeridini Števi, 2005 [sic]. Having
examined material of Sphenomerides, Calocarcinus and
Philippicarcinus, we are of the opinion that all three form
a coherent group, characterised by a generally broader
carapace, lack of setal rows on the tips of the ambulatory
dactyli, prominent heterochely (strongly asymmetrical
chelipeds), and living in deep sea soft and precious corals
or sponges. Recent expeditions have obtained a large
series of both Calocarcinus and Philippicarcinus from the
Philippines, and the differences are consistent (Peter
Castro and P. K. L. Ng, unpublished data). We here apply
the suprageneric taxon Calocarcininae Števi, 2005, for
these three genera. Following Article 24.2.1 of the Code,
we act as first revisers and select Calocarcinini Števi,
2005, as having priority over Sphaenomeridini Števi,
2005 [sic] which was published simultaneously with
Calocarcinini Števi, 2005. Clark & Ng (2006)
commented on the discordant classification presented if
the larvae of Quadrella are considered. The two trapezoid
genera associated with soft corals, Quadrella and
Hexagonalia, also have a very distinct carapace form and
front, and we thus also recognise a third subfamily,
Quadrellinae Števi, 2005, within the Trapeziidae.
Schweitzer (2005) argued that there were no clear grounds
to recognise the Tetraliidae as distinct from Trapeziidae as
proposed by Castro et al. (2003). Among the arguments
she presented was that the external features of trapeziids
and tetraliids, notably the fronto-orbital margins (and
carapace), were too similar to justify separating them.
While carapace proportions may be a useful generic or
specific character, its value as a familial character is
contentious. In many Xanthoidea, Pilumnoidea and
Goneplacoidea, the width varies substantially between
genera that are otherwise clearly linked via gonopodal and
abdominal features. Those of us working of modern (vs
fossil) crabs know that the carapace is a poor indicator of
relationships, and there is a good body of literature to
support this. An obvious recent case illustrating this
regards Tanaocheles and its two species, long either
associated with the Trapeziidae sensu stricto or Xanthidae
sensu stricto Externally, the two species of Tanaocheles
are identical to many species of Chlorodiella, and one of
the species (C. bidentata) was in fact placed there for over
a century. A close analysis of the male abdominal
condition and gonopods, complemented by larval data,
showed conclusively that Tanaocheles was actually a
pilumnoid, originally assigned to a new subfamily,
Tanaochelinae by Ng & Clark (2000) (here regarded as a
distinct family). If the abdomen and gonopods were not
considered, it would have been impossible to justify the
removal of Tanaocheles to the Pilumnoidea.
FAMILY DOMECIIDAE ORTMANN, 1893
Domoeciinae Ortmann, 1893
With regards to the key character of fusion of male
abdominal segments highlighted by Castro et al. (2003),
Schweitzer (2005) disregarded it as an important
character. While this can be debated, it is nevertheless true
that in many groups, especially within the xanthoids, there
is a consistency in abdominal fusion patterns that is useful
at the family or subfamily level. Whether the male
abdominal segments 3 to 5 are fused (immobile) or free in
the Trapeziidae and Tetraliidae, is a strong character
unequivocally splitting the genera into two groups. There
are no other well defined monophyletic brachyuran
families in which members have male abdomens of both
conditions. It may be argued that the tetraliids are no more
than a subfamily of the Trapeziidae (Števi, 2005, argues
it is only deserving of tribe level), but there is little doubt
that they form a monophyletic group. The emphasis on
carapace characters in paleontological studies is
understandable as fossils are rarely complete, and this
discipline certainly has more problems than those who
work with living species. Nevertheless, the value of a
character must be independent of its “availability”. Also

Notes
{1} This taxon was originally described only as a form of
Domecia acanthophora by Guinot-Dumortier (1964) and,
as such, the name is not nomenclaturally available under
the Code (Article 15.2). It was first used as a valid name
by Manning & Holthuis (1981) (who recognised the taxon
as a subspecies), but they incorrectly credited the
authorship to Guinot.
{2} The original description of Cancer tridentatus
Forskål, 1775 (from Suez) is too brief, but it fits the genus
Domecia as presently understood, and best matches
Domecia hispida Eydoux & Souleyet, 1842, which is
present in the Red Sea. We do not think it is possible to be
certain, and it is unfortunate that it is the oldest name. To
have the senior name replacing the well known name of
Domecia hispida serves no purpose, and we invoke Article
23.9.2 of the Code in suppressing the senior name. To
fulfil this article (i.e. used in 25 works, published by at
least 10 authors in the immediately preceding 50 years and
encompassing a span of not less than 10 years), we attach
a list of supporting references below (dating from 1957).
Even without a comprehensive
search, we easily
uncovered 45 references; the actual number is certainly
much higher.

Notes
{1} The taxonomy of the genus Tetralia is still unsettled,
with probably more species to be discovered (e.g., see
Trautwein, 2004).
{2} Despite the detailed revision of the complex
nomenclature associated with Tetralia species by Castro et
al. (2004), one remaining problem is with the absence of

Notes
{1} The name Trapeziidae Miers, 1886, is actually not the
earliest name for the group. There are two earlier names Trapezidés A. Milne-Edwards, 1862, and Trapeziden
Nauck, 1880. Both names, however, cannot be used as
they were used as French and German vernacular names,
respectively, and therefore not available under the Code.
{2} The current consensus is that the type species of
Trapezia Latreille, 1828, is Trapezia dentifrons Latreille,
1828, as designated by Rathbun (1930). There was,
however, an earlier designation by E. Desmarest (1858:
18), who, fortunately, also selected T. dentifrons as the
type species, so the nomenclature remains unchanged.
{3} The type locality for Trapezia rufopunctata (Herbst,
1799) was listed as unknown by Herbst (1799: 55) [as
Cancer rufopunctatus] and not Singapore as noted by
Castro et al. (2004: 42).

SUPERFAMILY XANTHOIDEA
MACLEAY, 1838
Remarks. – The present composition of the Xanthoidea
differs markedly from that first proposed by Guinot (1978)
and from other arrangements used by subsequent authors.
The taxa allied to Eriphiidae have been moved to their
own superfamily, Eriphioidea, while the Carpiliidae is
now likewise in the Carpilioidea. All the Pilumnidae and
allies are now also in the Pilumnoidea, while the
Trapeziidae, Domeciidae and Tetraliidae have been
transferred to the Trapezioidea. The family Pseudorhombilidae Alcock, 1900, long associated with the
goneplacids and their allies, is referred to the Xanthoidea
for the first time. Pseudorhombilids are much closer to
panopeids in regard to the form of the male abdomen and
gonopods.

{3} The identity of Galene hawaiiensis Dana, 1852, has
been problematic. It briefly described and only partially
figured from a single specimen from Hawaii, and never
since reported. Nothing currently known from Hawaii or
neighbouring waters looks even superficially similar. It
has been referred to Ozius and Eurycarcinus by some
workers. P. K. L. Ng has examined the problem and
believes that Galene hawaiiensis is synonymous with the
common American shore crab Panopeus herbstii. The
shape of the carapace and anterolateral margin figured by
Dana (1852a) matches P. herbstii well. Panopeus herbstii,
is not native to Hawaii but was introduced from mainland
America, and is now relatively common. It seems possible
that Dana obtained an alien specimen in Hawaii, or had an
American one which had been mislabelled. Similar
problems occur with some grapsids he described.

Notes
{1} Chasmophora Rathbun, 1914, was described as being
close to Euryplax (see Rathbun, 1914) although Tesch
(1918b) suggested that it was closer to genera like
Speocarcinus, Prionoplax and Cyrtoplax. Guinot (1969c:
714, fig. 134) figured its G1 and commented on its affinities,
but left its family position unsettled. Euryplax is currently in
the Euryplacidae, Speocarcinus in Xanthidae while
Prionoplax and Cyrtoplax are in Panopeidae. Števi (2005:
54) established a new subfamily, Chasmophorinae, for the
genus and transferred it to the Pseudorhombilidae, although
the absence of prominent denticles on the sides of the G1 (cf.
Guinot, 1969c: Fig. 134) suggests otherwise. Ng & Castro
(2007) provisionally kept it as a genus of Euryplacidae but in
view of its stout and relatively short G1 (Guinot, 1969c: Fig.
134), it should also not be retained there. Recently, as part of
their revision of the Euryplacidae, Peter Castro and P. K. L.
Ng examined specimens of Chasmophora macrophthalma
(Rathbun, 1898) and it is clearly not a euryplacid. Its male
andomen is relatively broad with segments 3–5 fused, and its
G1 is relatively stout. In the condition of its male abdomen
and gonopods, Chasmophora has clear affinities with
members of the Eucratopsinae in the Panopeidae, and as
such, it is referred there.

Notes
{1} Guinot (1969b: 522) commented on the generic
placement of Frevillea tridentata A. Milne-Edwards, 1880,
and suggested that it should be placed in a new genus. She
later described Frevillea tridentata in more detail and
established a new genus, Trapezioplax, for it (Guinot,
1969c: 712, Pl. 5 fig. 3, Figs. 128, 129) (see Guinot, 1971:
1082, for addendum on plate and figure numbers). She did
not resolve the precise family or subfamily placement of
Trapezioplax but noted it had several unusual features.
Števi (2005: 46) established a new subfamily,
Trapezioplacinae, for the genus, and placed it in the
Pseudorhombilidae. Ng & Castro (2007) provisionally kept
Trapezioplax in the Euryplacidae. As part of a revision of
the Euryplacidae, Peter Castro and P. K. L. Ng examined
material of this species and are now of the opinion that it
does not belong in the Euryplacidae as its male abdomen has
segments 3 to 5 fused and the G1 is relatively stout and
short. We agree that placing Trapezioplax in the
Pseudorhombilidae is the best option because although its
G1 structure is relatively simple, without any folds, its other
features agree (see Hendrickx, 1995b, 1998). However, we
do not see the need to recognise a separate subfamily, the
Trapezioplacinae Števi, 2005, for just one genus.

Euxanthinae: the major character used to separate the
Euxanthinae is that the first anterolateral tooth is separated
from the exorbital margin such that the anterolateral
margin is continued towards the anterior buccal cavity.
This character is strong for the central core of euxanthine
genera (like Carpoporus, Epistocavea, Euxanthus,
Glyptoxanthus,
Guinotellus,
Hepatoporus,
and
Hypocolpus) but can be difficult to appreciate in some
genera such as Alainodaeus, Medaeus, Medaeops,
Paramedaeus, and Monodaeus where it can become quite
vague. Davie (1997) commented that Paraxanthodes
(Xanthinae) is most closely related to Alainodaeus,
Medaeus, Medaeops, Paramedaeus, and Monodaeus and
the division that separates this group of euxanthines from
the Xanthinae proper is very tenuous. He considered the
latter five genera, at least, to form a monophyletic
grouping based on the general conformation of the
carapace, sternum, male abdomen shape. Davie (1997)
also drew comparisons between Alainodaeus and other
non-euxanthine genera such as Nanocassiope Guinot,
1967, and the panopeid genus Micropanope Stimpson,
1871, and this helps to reinforce how weakly the
Euxanthinae is defined at present. Ng & Clark (1993)
discussed the problems of distinguishing between the
subfamilies Xanthinae and Euxanthinae when they
described two new genera, Jacforus and Danielea. In
establishing the Ladomedaeidae, Števi (2005) argued
that the possession of sutures on all male abdominal
segments and having endostomial ridges were strong
characters. In all other aspects, Ladomedaeus Števi,
2005, is no more than an unusual Medaeus-like taxon (see
later comment under the genus and Maniel-Santos & Ng,
2007). More new genera and species of euxanthines have
recently been added from the Philippines (Mendoza & Ng,
in press).
Remarks. – This is one of the largest families in the
Brachyura, despite several modern revisions and reassessments. Even with the removal of taxa like the
Pilumnoidea and Eriphioidea into their own superfamilies,
the present Xanthidae is still very species-rich. Even with
the excellent work of Serène (1984), we believe that there
are still some difficulties in separating several of the
xanthid subfamilies, and some are probably artificial or
polyphyletic. While the core genera of each subfamily
appear distinctive, many of the peripheral genera
intergrade and seem almost arbitrarily assigned to their
subfamilies. Even subfamilies that seem clearly discrete,
such as the Cymoinae, Polydectinae, Kraussiinae,
Antrocarcininae and Zalasiinae, often have some genera
with characters overlapping with other xanthid groups. For
example in the Kraussiinae, Garthasia appears to link it to
the Xanthinae (Ng, 1993b); and in the Zalasiinae, genera
like Banareia and Calvactaea appear to link to the
Actaeinae (Guinot, 1976). The Etisinae and
Chlorodiellinae share spoon-tipped fingers and dactylopropodal locks on their legs, but if this phylogenetically
unites them, or instead represents convergence, as the
current subfamily recognition reflects, needs further
investigation. Subfamilies like the Euxanthinae,
Actaeinae, Liomerinae, Xanthinae and Zosiminae are
difficult to define as there are so many “exceptions”. We
do not propose to change the currently accepted view, but
we wish to point out some areas where we see particular
problems with the present classification. It may prove that
the family Xanthidae needs much more subdivision before
a classification can be derived that more truly reflects its
phylogenetic history, but such action needs a well
grounded and wide-ranging review of genera. The
The strongly differentiated basal tooth on the dactylus of
the major chela, is a common character in several
euxanthine genera such as Alainodaeus Davie, 1993,
Cranaothus Ng, 1993, Palatigum Davie, 1997,
Paramedaeus Guinot, 1967, Paraxanthodes Guinot, 1967,
Medaeops Guinot, 1967, Miersiella Guinot, 1967, and
Monodaeus Guinot, 1967. This character has not been
mentioned before as having potential phylogenetic
importance, but Ng (1993a) noted its presence in both
Cranaothus deforgesi Ng, 1993, and Paramedaeus
noelensis (Ward, 1934), and suggested that, as in Calappa,
it may be used to "peel" open gastropods (see Ng & L. W.
H. Tan, 1984a, 1985).
Liomerinae: the Liomerinae is also poorly defined. For
example Serène (1984: 16) in his key to subfamilies
merely uses an overall similarity of carapace shape:
“carapace is transversely oval, generally much broader
than long, with the dorsal surface convex, smooth,
granular or rugose and the regions prominent or hardly
indicated” versus “carapace xanthoid-shaped ...”.
However, given the enormous diversity of carapace shape
within the Xanthidae, and even between the subgenera of
Liomera, this does not seem enough, on its own, to
193
Ng et al.: Systema Brachyurorum Part I
adequately separate a subfamily. Nevertheless we agree
there is a general “liomerid-look” and we merely signal
here that it would be far more satisfying if more rigorous
characters could be found to separate the subfamily.
structures are present in other unrelated groups such as in
the Pilumnidae, and even the Majidae. The delineation
between some Etisinae and Chlorodiellinae (as
Chlorodiinae by most authors) is not always clear (see Ng
& Yang, 1998; Clark & Ng, 1999), and recent evidence
shows that the larvae of representative of both subfamilies
are also very similar (P. Clark, pers. comm.), so perhaps it
may prove that the Etisinae, Chlorodiellinae and
Cymoinae, at least, may form a monophyletic clade which
could require separate nomenclatural treatment.
Actaeinae: again poorly defined. The genera most closely
related to Actaea all share a similar look, but some of the
peripheral genera could easily be placed within the
Xanthinae. There does not seem to be any single
apomorphy that separates the Actaeinae from the
Xanthinae or Zosiminae. Serène (1984: 16) in his key
separates the later two groupings by this combination of
characters: “The front is bi- or quadrilobed, sometimes
with the submedians large and the laterals distinct. The
basal antennal article may or may not embrace the ventral
prolongation of the fronto-lateral margin. The regions of
the carapace are more feebly granular, never spinosed; the
anterolateral margins may or may not be emarginated with
more or less prominent teeth or lobes.” Individually all of
these character states are represented in the Actaeinae.
What is known about their larvae also does not help – all
indications are that we are dealing with a polyphyletic
grouping (see Ng & Clark, 1994). More work is clearly
needed to adequately define the Actaeinae.
Members of the Kraussinae, Antrocarcininae and
Zalasiinae are peculiar, and their relationships within the
Xanthidae will need to be re-examined. The family
Speocarcinidae Števi, 2005, placed in the Xanthoidea by
Števi (2005) is here recognised as a separate subfamily
in the Xanthidae until its affinities are better understood.
Members of this subfamily have traditionally been linked
with the Pilumnidae or Goneplacidae, but its relationship
is likely to be with the Xanthidae instead.
As has been discussed under the Trapezioidea, we believe
a separate superfamily is needed for Trapeziidae,
Tetraliidae and Domeciidae, which have been traditionally
associated with the Xanthidae or Xanthoidea.
Xanthinae and Zosiminae: The division of these two
subfamilies is “problematic”. In studying some xanthines,
Ng & Chen (2004: 2356) commented that “The close
affinities of Ovatis with Paratergatis and Pulcratis also
cast doubt on the validity of the Xanthinae and Zosiminae
… Paratergatis and Pulcratis are currently placed in the
Zosiminae. The only character that effectively
distinguishes the Xanthinae and Zosiminae at present is
whether the ambulatory articles are cristate but this is
unlikely to have significant phylogenetic importance. In
Ovatis, while none of the articles of the ambulatory legs
are distinctly cristate, it can be described as weakly so;
and those of Paratergatis are only weakly cristate. With
regards to their general features, Paratergatis, Pulcratis,
Ovatis and Liagore all appear to be related and as such,
their present allocation into two separate subfamilies
seems difficult to justify”. The larval data suggest the
same problems (Ng & Clark, 1998; Clark et al., 2004). In
the context of these and many other problems it is
premature to recognise more related “grey” subfamilies or

Etisinae, Chlorodiellinae and Cymoinae: these groups
have all been treated, at some time, as subfamilies of the
Xanthidae, and along with the Trapeziidae, Tetraliidae and
Domeciidae (now considered separate families), all share
an important apomorphy, viz., the ambulatory legs have a
dactylo-propodal articulation formed by a rounded
prolongation of the propodal lateral margin sliding against
and beneath a projecting button situated proximally on the
lateral margin of the dactylus. We consider, however, that
this character is probably paraphyletic and has evolved
independently in different lineages. The same, or similar,

Notes
{1} Cancer occultus Herbst, 1783, was only briefly
described as a very small species (3 “lines”) from Indian
Seas, and red in colour with black-tipped fingers, a
carapace with rounded margins, converging sides, slightly
swollen and with small chelipeds, the smaller one of
which has a cylindrical and delicate pincer (Herbst, 1783:
137). The description is too brief and there are no figures.
Our best guess is that this is a species of Liocarpilodes or
the like. It may even be a species of Chlorodiella although
all these species have dentate carapace margins. It is really
not possible to be more precise. With regards to Cancer
206
THE RAFFLES BULLETIN OF ZOOLOGY 2008
lapideus Herbst, 1785, this species was provided with a
very simple and small figure (Herbst, 1783: 185, pl. 11
fig. 64), but it is not helpful. It is supposed to have a floral
like pattern on its small carapace, and a stone like
appearance. It may be some sort of xanthid or xanthoid,
but we cannot be sure. There are no known types (K.
Sakai, 1999).
case with the genera is pending ICZN approval, the
subfamily name Chlorodiellinae is available as of this
publication.
{7} In the last revision of Pilodius Dana, 1851, by Clark
& Galil (1993), the type species was stated as Chlorodius
pilumnoides White, 1848, by original designation. Serène
(1984), however, stated Pilodius pubescens Dana, 1852,
was the type species. Dana (1851b: 126) when
establishing Pilodius, did not name any included species,
whereas Dana (1852a: 80) listed four species (Chlorodius
pilumnoides, Pilodius pubescens Dana, 1852, P. pugil
Dana, 1852, and P. scabriculus Dana, 1852) and says in
the generic description “Chlorodius pilumnoides, White,
hic pertinet”, but again no type was indicated. Nor did
Dana (1852b) designate a type. Clark & Galil (1993)
probably took Dana’s (1852a) statement to suggest that he
regarded Chlorodius pilumnoides as the “typical member”
Pilodius, and recognised it as the type species. Article 67.5
of the Code, however, argues for a “rigid” interpretation of
what constitutes a valid designation, and would dismiss
this. Any of the four species listed in Dana (1852a) would
be available for nomination as a type species. Serène
(1984: 233) was apparently the first to nominate, through
his statement, that Pilodius pubescens is the type species,
and his action therefore has precedence. Even if
Chlorodius pilumnoides or Pilodius pubescens were to be
the type species it would not change the composition of
the genus as presently understood (see Clark & Galil,
1993).
{2} The authorship for these taxa should be “Lucas, in H.
Milne Edwards & Lucas, 1844”, rather than just “H. Milne
Edwards & Lucas, 1844” (Guinot & Cleva, 2002).
{3} Article 10.2 of the Code states that names for forms
and other infrasubspecific taxa established after 1961 are
not available. As such, the many of the forms of the
common reef actaeine Paractaea rufopunctata (H. Milne
Edwards, 1834) recognised by Guinot (1969d) and Serène
(1984) are not valid names. Two of these, Paractaea
rufopunctata forma africana Guinot, 1969, and Paractaea
rufopunctata forma plumosa Guinot, 1969, were validated
subsequently (Guinot, 1976; Sakai, 1976). Castro &
Eldredge (in preparation), will be recognising three of
these taxa (forma intermedia Guinot, 1969, forma
primarathbunae Guinot, 1969, and forma tertiarathbunae
Guinot, 1969) as distinct subspecies.
{4} Serène (1962) established Pseudactea with this
spelling, and used it again in 1965. Throughout these
papers, he used the name “Actea”. Later, Serène (1968:
79) corrected the spelling to “Pseudactaea” which
indicates that his original spelling was a lapsis. This
emended spelling has since been used by all subsequent
workers. The name was clearly intended to be formed
using Actaea De Haan, 1833, as the stem. All authors
since have used the spelling “Pseudactaea”, including the
major revision of the Xanthidae by Serène himself (1984).
Article 33.2.3.1 of the Code states that “when an
unjustified emendation is in prevailing usage and is
attributed to the original author and date it is deemed to be
a justified emendation”. On this basis, we follow
prevailing usage and recognise Pseudactaea Serène, 1962,
as the correct name.
{8} Pilodius kauaiensis Edmondson, 1962, is
problematic as no males are known. P. K. L. Ng has
examined the type specimen in the Bernice P. Bishop
Museum, as well as one in the ZRC recently collected
from Oahu, Hawaii. Its antennal structure and general
carapace features indicate that it is not a pilodiine, and
may warrant its own genus, but male abdominal and
gonopod characters will need to be examined before its
taxonomic status can be clarified.
{9} Clark & Ng (1999) clarified the taxonomy of the
poorly known species Chlorodius miliaris A. MilneEdwards, 1873 (type locality New Caledonia), and showed
that it differed markedly from other genera in the
subfamily. They then placed it in a new monotypic genus,
Sulcodius. This species, however, is almost certainly
identical with another poorly known species, Etisus
deflexus Dana, 1852, originally described from Fiji. On
the basis of the description and figures, and the detailed
redescription of the species from Palau by Takeda (1971),
we have little doubt that Etisus deflexus Dana, 1852, is a
senior subjective synonym of Chlorodius miliaris A.
Milne-Edwards, 1873, and the two are here synonymised.
{5} Cancer nodulosus Fabricius, 1781, is almost certainly
a member of the Actaeinae (Xanthidae). The species was
obtained by Banks but the type locality is not known.
Banks not only collected along the eastern coast of
Australia, but also in the West Indies (and perhaps other
localities). He was part of James Cook’s first voyage
around the world, and collected throughout the expedition.
The characters in the description of Fabricius are general,
equally apply to a number of species, and we believe are
inadequate to define C. nodulosus. The types are lost, and
therefore a neotype would be required to validate the
species.
{10} In describing Edwardsium, Guinot (1967a) did not
assign it to any subfamily. A re-examination of specimens
of Edwardsium spinimanum (H. Milne Edwards, 1834),
the type species of the genus, indicates that it is best to
place it in the Euxanthinae for the moment as it has most
of the features here diagnosed for the subfamily (J. C. E.
Mendoza & P. K. L. Ng, unpublished data).
{6} The well known subfamily name, Clorodiinae Dana,
1851 (sic Chlorodiinae), is actually a junior synonym of
Atelecycylidae, and not a xanthid. A new name needs to
be established for the group previously assigned to this
subfamily, for which the name Chlorodiellinae was
proposed by Ng & Holthuis (2007). While the overall
207
Ng et al.: Systema Brachyurorum Part I
{11} Guinotellus melvillensis Serène, 1971, was described
on the basis of a small male specimen from the Philippines
(see also Serène & Umali, 1972). Recently, many new
specimens were found, including large adult males, and a
complete redescription has been provided (Mendoza et al.,
in press). Although peculiar in its dome-shaped carapace,
it nevertheless has all the diagnostic features of the
Euxanthinae and should be placed there.
typical condition in the Xanthidae s .str. in which
segments 3 to 5 are fused. However the sutures
separating segments 3 to 5 can still be visible, even
though these segments are immovable, i.e. effectively
fused (see Ng and Chia, 1994). Such a condition is
known for xanthid genera like Neoxanthias. Števi
(2005) took the reported differences at face value, and
as a result, unnecessarily (in our opinion) recognised a
family-level taxon for the genus. While a new genus is
warranted, it is easily accommodated in the Euxanthinae
of the Xanthidae sensu stricto Manuel-Santos & Ng
(2007) have discussed this matter at length after
examining specimens of L. serratus as well as a new
species from the Philippines.
{12} In the original description of Hypocoelus Heller,
1861, two species were listed, Cancer sculptus H. Milne
Edwards, 1834, and Cancer exsculptus Herbst, 1790.
However, as he regarded C. exsculptus to be a synonym of
Cancer sculptus, he effectively only treated one species.
As such, Cancer sculptus H. Milne Edwards, 1834, is the
type species of Hypocoelus Heller, 1861, by monotypy.
Some authors suggest that the type species of Hypocoelus
Heller, 1861, was selected by Guinot-Dumortier (1960).
Guinot-Dumortier (1960) by indicating Melissa
diverticulata Strahl, 1861, as the type of Hypocolpus, de
facto also selected Cancer sculptus H. Milne Edwards,
1834, as the type species of Hypocoelus since she (p. 180)
cited that species in the synonymy of Hypocolpus
diverticulatus. The above comments are largely irrelevant
however as Hypocoelus Heller, 1861, is pre-occupied by
Hypocoelus Latreille, 1834, and has been replaced by
Hypocolpus Rathbun, 1897. Although Cancer sculptus H.
Milne Edwards, 1834, is a junior homonym and
nomenclaturally invalid, it is nevertheless an available
name, and may be used as a type species under the Code
(Article 69.2.2).
{14} Medaeops Guinot, 1967, is clearly heterogeneous,
and a revision will be needed to ascertain if it is
monophyletic, as well as it affinities with the closely
related Mondaeus Guinot, 1967 (see Davie, 1997; Ng &
McLay, 2007)
{15} Števi (2005: 133–134) named many new genera
none of which are nomenclaturally available as no
diagnoses were given. From our own unpublished data,
some are valid taxa. These will need to be formally
described by the various workers currently revising these
taxa.
{16} Lanchester seemed to have run out of luck with this
taxon. Lanchester (1900) first established Actaeopsis, for a
new xanthid from Malaya. Later, realising that this name
was pre-occupied by Actaeopsis Carter, 1898, for a fossil
crustacean, he proposed a replacement name, Actites
Lanchester, 1902. This name has since been adopted,
though usually as a subgenus of Liomera Dana, 1851 (see
Serène, 1984). The morphological differences are
significant enough, however, to recognise it as a distinct
genus (see Davie, 1992; Ng, 2002c). Unfortunately for
Lanchester, the name Actites Lanchester, 1902, is also preoccupied by Actites Billberg, 1828, named for a bird.
Although most current authors cite the year of publication
as 1901, as discussed earlier in the Introduction, the
December 1901 issue of the Proceedings of the Zoological
Society of London, in which the name appeared was not
actually published until 1902. As there are no other
synonyms for Actites Lanchester, 1902, we here propose a
replacement name, Actiomera. The type species remains
as Actites erythrus Lanchester, 1902. The name is derived
from an arbitrary combination of Actites and Liomera, and
the gender is feminine.
{13} While he did not formally describe Ladomedaeus,
Števi’s (2005) description of the new family
Ladomedaeidae (here synonymised under Euxanthinae),
stated that the new genus Ladomedaeus was the type
genus, and assigned M. serratus Sakai, 1965, as its type
species, all in the same paragraph. This is valid under the
Code, making both Ladomedaeidae Števi, 2005, and
Ladomedaeus Števi, 2005, available names. The generic
assignment of Medaeus serratus Sakai, 1965, was
considered as uncertain by Guinot (1967a: 374), who
commented “… est une forme à part (en particulier les
crêtes endostomiennes sont bien définies, complètes.
Nous laissons pour l’instant imprécise son appartenance
générique, mais nous avons des raisons de croire qu’il
s’agirait plutôt d’un Pilumninae-Eumedoninae”.
However, she made an additional comment a year later
“Dans la meme note (ibid., p. 374), nous avions suppose
que Medaeus serratus Sakai, 1965, pourrait avoir
quelques liens avec les Pilumninae-Eumedoninae. Cette
hypothèse nous apparaît maintenant erronée, et nous
explique-rons ultérieurement notre point de vue sur cette
question.” (Guinot, 1968c: 334). In any case, the
gonopods as described and figured by Sakai “(1965:
101, Fig. 3a, b) are typical for most Xanthidae; as is the
general facies of the species (see also Ikeda, 1998: 128,
pl. 58). The presence of distinct endostomial ridges,
however, is unusual. Sakai (1965: 101) had also
described the male abdomen as consisting of “… seven
distinct segments as in the female”, and this may have
been part of the problem. This is certainly not the
{17} Leptodius macandreae Miers, 1881, was described
from the Canary Islands, in a footnote by Miers (1881:
215, 216), and he noted that it was “… very nearly allied
to Leptodius dispar, Stimpson, a Cuban species …”
(Miers, 1881: 216). This species is now in Paraliomera,
and we tentatively refer Miers’ species there.
{18} The systematic position of Speocarcinus Stimpson,
1859, has been uncertain for some time (see Guinot,
1969c; Ng, 1987), even after a number of species
previously assigned to the genus have been transferred to
208
THE RAFFLES BULLETIN OF ZOOLOGY 2008
looks very much like species of Xanthias, but it has
spinous legs and chelipeds, as well as a relatively
flattened and spinous chela with sharp fingers. It is
clearly a xanthid, and likely to be in the subfamily
Xanthinae as defined at present. In view of the unsettled
taxonomy of the many of the xanthid subfamilies,
particularly Xanthinae, it premature to recognise the
Linnaeoxanthinae Števi, 2005. We have tried to reexamine the specimen, supposedly in the Cambridge
University zoology collections, but the specimen could
not be found (R. Symonds & Paul Clark, pers. comm.).
With regards to the genus Linnaeoxanthus Števi,
2005, although Števi (2005) did not formally describe
it, his description of the new family, Linnaeoxanthinae
Števi, 2005, the statement that the new genus
Linnaeoxanthus was the type genus, and the assignment
of Pilumnoplax acanthomerus Rathbun, 1911, as its type
species, all in the same paragraph, is valid under the
Code, making both names available.
other genera and families. The affinities of the genus are
nevertheless with the xanthids, and Števi (2005)
correctly assigned it to the Xanthoidea. In fact, with
regards to the form of the male abdomen (segments three
to five fused), presence of a relatively slender G1 and a
relatively short G2 (but prominently longer and less
sigmoidal than those in pilumnoids), there is nothing to
distinguish Speocarcinus from xanthids. We therefore
believe that it is more logical to regard Speocarcinidae
Števi, 2005, as a subfamily of the Xanthidae.
{19} The status of the Coralliopinae Števi, 2005, is not
settled. In establishing Coralliope, Guinot (1967a: 355)
commented that it seemed to have relationships with
trapeziids or domeciids. Typically, Števi (2005)
established a new subfamily for the genus and commented
that it may be in the Trapeziidae, but with doubt. Looking
at the general facies of the members of the genus, and the
G1 structure, it seems to have more affinities with the
Domeciidae. This matter, however, needs more study, and
until then, we prefer to leave it in the Xanthidae.
{23} Devi (1991) described what she thought was a new
species of Demania, D. shyamasundari, from the Bay of
Bengal in India, but her figures and descriptions
(including the fresh colour) match those of Neoxanthias
michelae Serène and Vadon, 1981 (see type description,
Ho et al., 2000; Ng et al., 2001).
{20} The status of Eucratodes A. Milne-Edwards, 1880,
has not been clear. Described for a single species,
Eucratodes agassizii A. Milne-Edwards, 1880, from the
Gulf coast of Mexico and Puerto Rico, Rathbun (1930:
470, 471) commented that it was close to
Metopocarcinus Stimpson, 1860, and left it in her
Xanthidae. Metopocarcinus is now in the Panopeidae.
Balss (1957) agreed and left it in the Xanthidae. Guinot
(1969c: 722, Fig. 145, 146) discussed the position of
Eucratodes and provided figures of the G1 and male
sternum. She commented that it was not really a
goneplacid, panopeid or pilumnid and indicated it had
more xanthid tendencies. Števi (2005: 46) suggested
establishing a new subfamily, Eucratodinae Števi,
2005, for the genus and placed it in the Xanthidae. Ng &
Castro (2007) provisionally left it in the Euryplacidae
but as its male abdomen has segments 3 to 5 fused and
the G1 is neither slender nor long, it should be
transferred out. An ongoing revision of the Euryplacidae
by Peter Castro and P. K. L. Ng suggests that the G1
structure of Eucratodes agassizii is certainly xanthid in
form (more xanthine), and although the carapace is
“euryplacid-like”, there are some xanthids that are
superficially look like this as well. We retain the genus
in the Xanthinae for the time being, and provisionally
keep the Eucratodinae Števi, 2005, in the synonymy
of Xanthinae. The various groupings in the Xanthinae
need to re-evaluated systematically with all the genera
re-examined before any further splitting be done.
{24} Cancer tinctor Fabricius, 1798, has been forgotten
since its description. In the ZMUC is a type specimen
(male, 50.0 by 31.1 mm, ZMUC Cru 108), and appears to
belong to Xantho sensu stricto. It is closest to Xantho
poressa (Olivi, 1792), with which we synonymise it
pending further study.
{25} In establishing a new tribe, Alcock (1898) used the
spelling “Zozymoida”. This was because he had used the
incorrect spelling for the type genus, Zosimus Leach,
1818. The original spelling used by Leach (1818) was
with an “s”, but H. Milne Edwards (1834) used a different
spelling, Zozymus, and the latter has been used by many
subsequent workers. The original spelling for the genus by
Leach must be maintained, and as a consequence, the
spelling for the subfamily as well.
{26} The synonymy of the well known poisonous reef
xanthid crab Atergatis floridus (Linnaeus, 1767) with
Cancer ocyroe Herbst, 1901, and Atergatis compressipes
MacLeay, 1838, has not been questioned for many
decades. Nomenclatural problems with the name Cancer
floridus with the Atlantic aethrid Hepatus epheliticus
(Linnaeus, 1763) have been resolved by Ng and Holthuis
(1993) with the selection of a neotype for the latter
species. Ng & Davie (2007) recently showed that Cancer
ocyroe Herbst, 1901, is a valid species of Atergatis,
distinguished by its different carapace physiognomy and
mouthpart structure, and most prominently, by its
completely different colour pattern in life.
{21} An unusual species of Liagore which does not
show any colour patterns on the carapace was recently
described by Ng & Naruse (2007) from Vanuatu.
{22} Števi (2005) established a new genus
(Linnaeoxanthus) and a new subfamily (Linnaeoxanthinae) in the Xanthidae for a peculiar species first
described from the Indian Ocean by Rathbun (1911) as
Pilumnoplax acanthomerus (based on a male and an
ovigerous female). The carapace of P. acanthomerus
{27} The characters that separate Zosimus Leach, 1818,
and Platypodia Bell, 1835, are not distinct. Characters

colours or prominent color patterns. Zosimus aeneus is a
well known brightly coloured and strikingly patterned
species, and Z. hawaiiensis also has a bright orange colour
with banded legs (P. K. L. Ng, fresh specimen). The
revision of these taxa is now currently under preparation
by the authors (Davie & Ng, in prep.).
pereiopods, are not reliable. In an appraisal of these
genera, Guinot (1967b: 559) suggested that two species
previously allied with Platypodia, Lophactaea fissa
Henderson, 1893, and Actaea hawaiiensis Rathbun, 1906,
may be better accommodated within Zosimus. She also
suggested that the two taxa may be synonymous (see also
Davie, 2002: 567). The generic placement of two species
currently placed in Platypodia, Lophozozymus actaeoides
A. Milne-Edwards, 1867, and Lophactaea maculata De
Man, 1888, may not belong there. In the ZRC are
specimens of Actaea hawaiiensis, Lophozozymus
actaeoides and Lophactaea maculata, as well as many of
the type species of both genera. Examing these, we (P. K.
L. Ng & P. J. F. Davie) are confident that Lophactaea
fissa and Actaea hawaiiensis are two distinct species,
differing markedly in carapace form. With regards to
Zosimus and Platypodia, we propose that Zosimus be
defined primarily by the last anterolateral tooth been
acutely triangular and directed laterally; and the outer
surface of the ambulatory propodus possessing a distinct
longitudinal groove between two raised areas which may
be covered with granules or vermiculations. To this
effect, we here transfer Lophozozymus actaeoides,
Lophactaea maculata, Lophactaea fissa and Actaea
hawaiiensis to Zosimus. It is also interesting to note that
there is a prominent vermiculated pattern of granules on
the carpus of the cheliped in the type species of Zosimus,
Z. aeneus. From Z. maculatus, Z. hawaiiensis to Z.
actaeoides, this pattern gradually becomes less obvious.
Cancer sculptus Herbst, 1794, should also be referred to
Zosimus as defined here. The species has been classified
in Platypodia (see K. Sakai, 1999: 33) but it is clearly
very close to Z. fissa. It is quite possible that Z. sculptus
is synonymous with Z. fissa, the two agreeing in most
characters. One species of Platypodia needs to be referred
elsewhere, Platypodia anaglypta (Heller, 1861)
(originally in Atergatis). The last anterolateral tooth is
separated from the rest of the teeth by a prominent
sinuous groove which is absent in the other Zosimus and
Platypodia species. In addition, this is the smoothest of
all known Platypodia species. In fact, it looks much more
like a species of Lophozozymus (which also has the
groove on the last anterolateral tooth) and we refer it
there for the moment. This revised classification has
support from their live colours. Like many species of
Lophozozymus, L. anaglyptus has a prominent colour
pattern, with a prominent purple carapace with bright
yellow spots. With the exclusion of the above species of
Platypodia into Zosimus and Lophozozymus, all the
remaining species are relatively drab greenish-brown
species without bright
{28} The identity of Atergatis limbatus Streets, 1877, and
Cancer limbatus H. Milne Edwards, 1834, will need to be
checked; the close similarity of their names suggests a
connection and both are now in Platypodia. Rathbun
(1906: 845) cited Streets’ (1877) species, A. limbatus, as a
junior synonym of P. eydouxi without comment. In her
later synopsis of the American fauna, Rathbun (1930: 246)
listed Cancer limbatus H. Milne Edwards, 1834, as a
synonym of P. granulosa (Rüppell, 1830).
{29} The identity of Cancer miliaris Latreille, in Milbert,
1812, is a problem. It was described briefly from
Mauritius by Latreille (1812: 273), and from what we can
gather, it seems to be a species of Zosimus or Platypodia,
or perhaps even Xanthias. The carapace regions are well
developed, the surface is granular and there are many red
spots. It is not possible to be certain, as there are a number
of species with these characters. Certainly, this is not the
same species as Chlorodius miliaris A. Milne-Edwards,
1873 (type locality New Caledonia) (junior synonym of
Etisus deflexus Dana, 1852, type locality Fiji), now in
Sulcodius Clark & Ng, 1999.

Ng et al.: Systema Brachyurorum Part I
from the rest of the grapsoid families ... the combination
of antennal and telson morphology, and setation of the
second maxilliped endopod (1, 1, 6) is not present in any
other family of grapsoids. This seems to reflect a
possible monophyletic origin of the Gecarcinidae, which
was also suggested for the genera Cardisoma and
Gecarcinus based on mtDNA sequence data …... Within
the Gecarcinidae, the only important difference is the
setation of the maxillar endopod. According to this, the
two major groups can be distinguised within the
Gecarcinidae: Epigrapsus, Gecarcinus and Gecarcoidea
on one hand (with a 2, 2 setation), and the genus
Cardisoma on the other hand (with 2, 3)” (Cuesta et al.,
2002: 1681, 1683). Our ongoing studies of these genera
support these conclusions. Clearly, the genera
Cardisoma and Discoplax share a suite of characters that
indicate that they deserve subfamilial recognition. On the
basis of the adult morphology, Epigrapsus is also
phylogenetically distinct from Gecarcinus and its allies,
suggesting that it should also be separated. A fuller
analysis of the relationships within the family is
currently in progress (Davie & Ng, in prep.).
SUPERFAMILY GRAPSOIDEA
MACLEAY, 1838
Remarks. – Schubart et al. (2006: 198) argue on the basis
of their molecular (12S and 16S rRNA) concensus tree
that “... it becomes evident that both superfamilies,
Grapsoidea and Ocypodoidea, are not monophyletic in
their current composition, as exemplified by a proposed
sister
group
relationship
of
Varunidae
and
Macrophthalmidae. These results confirm those from
previous molecular studies and we therefore propose to
refrain from the traditional use of the Grapsoidea and
Ocypodoidea as monophyletic superfamilies and treat the
constituent families separately.” We do not agree with this
recommendation and continue here to recognise these as
valid superfamilies pending stronger evidence to the
contrary. We concede that the genes they have been using
work well at the genus level, both reinforcing our
morphological generic concepts, and pointing out
instances where species have been wrongly placed.
However, at the higher level classification, the conclusions
they have drawn from their genetic data seem more
questionable. For example, while they point out that their
results show a sister relationship for the Varunidae and
Macrophthalmidae, they pass over the fact that Mictyris is
in the same monophyletic grouping and sister to these
families. This seems most unlikely, and in fact, each of
these families has a suite of significant morphological
characters that strongly contradict any suggestion of them
belonging to the same evolutionary lineage. Similarly,
Schubart et al. (2006) showed that the Plagusiidae is sister
to the Gecarcinidae, whereas our morphological datasets
strongly contradict such an interpretation. Interestingly,
our hypothesis was supported by a subsequent genetic
analyses (N. K. Ng et al., 2007), that showed plagusiids to
be well separated. While we believe that genetic analyses
will eventually help successfully resolve these higher
order relationships, we are of the opinion that it will
require the use of additional and/or more conserved genes.
Our morphological understanding of higher taxonomic
groupings has, after all, grown out of the analysis and
interpretation of a wide array of characters. The truth will
ultimately, almost certainly come from a consensus of
both molecular and morphological approaches.

Remarks . – Available larval and DNA evidence suggests
that the American and east Atlantic genera Glyptograpsus
Smith, 1870, and Platychirograpsus De Man, 1896, are
distinct from other grapsoids, and because of this Schubart
et al. (2002) established a new family for them (see also
Cuesta & Schubart, 1997; Schubart et al., 2006). The adult
morphological characters, however, show no major
differences to distinguish them from the Varunidae.
Nevertheless, we provisionally continue to recognise the
Glyptograpsidae. This is especially in view of the fact that
the Varunidae sensu lato is also being revised and
redefined, e.g. most recently, the genus Xenograpsus, was
transferred to its own family (N. K. Ng, et al., 2007).

THE RAFFLES BULLETIN OF ZOOLOGY 2008
2002). Davie (2002) transferred Euchirograpsus and
Miersiograpsus to Plagusiinae from Varuninae and
Grapsinae respectively. Our re-examination of specimens
showed that both Euchirograpsus and Miersiograpsus
have the male abdominal segments 3–6 fused, an
apomorphy otherwise not known in the Grapsidae sensu
lato. Also we found that there are shallow grooves along
the front which appear to mark incipient antennular clefts,
like those found in Plagusia and Percnon. This, along
with the DNA data, is sufficient grounds to formally place
them in the Plagusiidae. However, there are a number of
what must be considered as plesiomorphic grapsid features
which are still retained by both Euchirograpsus and
Miersiograpsus, such as a relatively broader front which
overhangs the epistome, and the third maxilliped with a
normal long exopod that bears a well developed palp.
Interestingly Guinot & Bouchard (1998: 664) also
recognised that as a “grapsid”, Euchirograpsus was
unusual in its type of push-button abdominal locking
mechanism: “... a specially acute button and a socket
posteriorly defined by a strongly calcified border, which
suggests that the genus is misplaced in the Varuninae.”

With regards to Percnon, DNA (Schubart et al. 1999) and
larval evidence (J. Cuesta, pers. comm.) have suggested
that Percnon is different and doubtfully placed in the
Plagusiidae. On the basis of adult morphology, we concur
that Percnon species are highly derived, and have many
unique generic apomorphies, probably related to their
unusual habit of living subtidally on rock faces exposed to
heavy wave action. These, combined with unusual sternal
characters and the unique grapsoid condition of the male
abdomen having only segments 3–5 fused, lead us to
support the recognition of a separate subfamily, Percninae,
a taxon first erected as a tribe by Števi (2005).
Notes
{1} The Plagusiinae has long being classified as a
subfamily in the Grapsidae and traditionally contained
only Plagusia and Percnon, which seem to be allied by the
unusual clefted front, fused male abdominal segments, and
reduced exopod of the third maxilliped which lacks a palp.
Another two diagnostic characters are the unusual
abdominal press-button locking mechanism (see Guinot &
Bouchard 1998) and raised rim adjacent to press-button at
the suture between sternites 5/6. An emended diagnosis
for the Plagusiidae is provided: Carapace subcircular to
quadrate; surface smooth and glabrous to strongly
tuberculate and tomentose. Front of two types: a) narrow,
not overhanging epistome although may be armed with
projecting spines; divided into three lobes by deeply cleft
antennular fossae, such that antennules visible in dorsal
view, or b) broader and more grapsid-like, overhanging
epistome; shallow grooves marking incipient antennular
clefts, but not obvious in dorsal view. Anterolateral
margins with one to several teeth or spines behind
exorbital angle. Lower border of orbit curved, continued
as ridge to meet prominent anterior border of buccal
cavern. Antennal flagellum short. Third maxillipeds not
completely closing buccal cavern; merus and ischium
without oblique setose crest; exopod slender, with or
without flagellum; palp articulating near antero-external
angle of merus. Male abdomen entirely covering sternum
between last pair of legs; segments 3–6 or 3–5 fused,
sutures may be still evident. Abdominal locking
mechanism press-button type, corneous rim or constricted
apex present in Plagusia and Percnon; suture between
sternites 5/6 with raised rim adjacent to press-button.
{3} Pachygrapsus polyodous Stebbing, 1921, was
described on the basis of one specimen from Natal in
southern Africa. The carapace form, armature of the
anterolateral margin, and structure of the chelipeds,
closely resemble species of Euchirograpsus, and it has
been tentatively referred to this genus by Poupin et al.
(2005). However, it differs from all known
Euchirograpsus in having the ventral margins of its
ambulatory meri prominently serrated, suggesting that it
may well belong to its own genus. Unfortunately the type
is apparently lost. Barnard (1950: 118) stated that “only
one male specimen was captured. It has not been returned
to the South African Museum, so I am unable to check
Stebbing’s description or give further details”. Stebbing’s
South African collection was largely donated to the
Natural History Museum, London, but the holotype of P.
polyodous is not found there and is probably lost (P. F.
Clark, pers. comm.). Nevertheless, it is clear that
Stebbing’s species does not belong to Pachygrapsus.
In a preliminary tree, Schubart et al. (2000) questioned the
then taxonomic position of Euchirograpsus, suggesting
that its affinities were with the plagusiines (Schubart,
{4} Plagusia tuberculatus is usually credited to Lamarck
(1818), but the correct author should be Latreille, in
Milbert, 1812 (see Notes in INTRODUCTION).
{2} The atypical Plagusia glabra Dana, 1852, was
recently referred to its own genus by Guinot (2007).

{1} Henri Milne Edwards (1837) linked Sesarma pisonii
with Cancer hispanus Herbst, 1794, but this is incorrect.
Herbst’s species may be a varunid and we have tentatively
placed it under incerta sedis in the Varunidae (see point 14
in Notes for Varunidae).
{2} The Commission was asked to give priority to
Sesarma rubripes Rathbun, 1897, over Sesarma trapezium
Dana, 1852, when the two names are regarded as
synonymous; which the ICZN ratified as Opinion 1140
(ICZN, 1979).
{3} The poorly known Sesarma (Sesarma) philippinensis
Rathbun, 1914, was suspected to be a species of
Bresedium by Serène & Soh (1970), and this has been
confirmed by the examination of recently collected
specimens from the Philippines. Morphological and
molecular data (P. K. L. Ng and C. D. Schubart) suggest
that Bresedium and Sesarmops are close sister taxa.

single type species, C. haematocheir, that has a distinctive
thoracic sternal structure (see Ng & Liu, 1999). All other
species will need to be transferred elsewhere (P. K. L. Ng
and C. D. Schubart, ongoing study using morphological
and molecular data). In particular, the well known IndoWest Pacific species Chiromantes dehaani (H. Milne
Edwards, 1853) must be referred to a separate genus,
together with Chiromantes boulengeri (Calman, 1920),
Pseudosesarma patshuni (Soh, 1978), Pseudosesarma
crassimanum (De Man, 1887), Pseudosesarma johorensis

will thus need to be revised accordingly.
three may be synonymous.
{13} Holthuis (1977: 172) and Abele (1979: 177) both
pointed out that Beanium Serène & Soh, 1970 (as
Nanosesarma (Beanium)), is a junior subjective synonym
of Nanosesarma Tweedie, 1950. Serène & Soh (1970)
wrongfully proposed Sesarma minutum as the type species
for Nanosesarma which already had as its type S.
andersoni De Man, 1887, by original designation of
Tweedie (1950). They further proposed S. batavicum
Moreira, 1903, as the type for their new subgenus
Beanium and included in Nanosesarma (Beanium), S.
andersoni De Man, 1887, already the type of
Nanosesarma sensu stricto. Because Beanium is a junior
synonym of Nanosesarma, S. batavicum thus has no
formal generic type status. A new name will be needed for
the group of species Serène & Soh (1970) included in their
concept of Nanosesarma (Nanosesarma) (e.g. N. minutum
(De Man, 1887); N. pontianacense (De Man, 1895); N.
vestitum (Stimpson, 1858); N. jousseaumei (Nobili, 1906)
and N. tweediei Serène, 1967), if indeed this group is
justifiably separable from Nanosesarma proper. Davie (in
prep.) is currently revising Nanosesarma, and further
discussion on the polyphly of Nanosesarma, and the
designation of new names, as required, will be deferred
until this revisionary paper.
{6} Sesarma (Sesarma) eulimene De Man, 1895, and
Sesarma (Holometopus) ortmanni Crosnier, 1965, are
currently in Chiromantes (sensu Ng & Liu, 1999), but an
ongoing revision of this genus by P. K. L. Ng and C. D.
Schubart (using morphological and molecular data) shows
that they should be transferred a new genus (see point 5).
{7} Sesarma neglectum De Man, 1887, has long been
regarded as a junior subjective synonym of Chiromantes
dehaani (H. Milne Edwards, 1853), but both are separate
species, albeit in the same genus (see Ng et al., 2001). The
type of S. neglectum is no longer extant but P. K. L. Ng
and C. D. Schubart have examined topotypic material
from Shanghai (China) and it is clearly a good species.
Contrary to Ng et al. (2001), “Chiromantes neglectum” is
not present in Taiwan but occurs only in the upper part of
mainland China. Chiromantes dehaani is present
throughout Japan (type locality), Taiwan and through to
Hong Kong and southern China.
{8} Sesarma obtusifrons Dana, 1851, is currently in
Chiromantes (see Ng & Liu, 1999) but has affinities with
Stelgistra. However, ongoing studies of this and allied
species by P. K. L. Ng and C. D. Schubart (using
morphological and molecular data), indicates that it should
be referred to its own genus (see point 5).
{14} Sesarma jousseaumei Nobili, 1906, had been
regarded as a senior synonym of Sesarma (Sesarma)]
gordoni Shen, 1935 but a soon to be completed revision of
the genus by P. J. F. Davie suggests it is a valid taxon. On
a nomenclatural matter, Shen (1935: 19) specifically
thanks Isabella Gordon for her help and guidance, and
several pages later (Shen, 1935: 21), names a new species,
“Sesarma (Sesarma) gordoni, sp. nov.”. It is reasonable to
construe that his intention was to honour Gordon, and thus
the name should have been spelled as “gordonae” (female
ending). However, nowhere does Shen explicitly state that
he was naming it for Dr Gordon. In this case, we interpret
the Code very strictly and maintain the use of the spelling
“gordoni”.
{9} The types of Holometopus serenei Soh, 1978, are
small specimens of Chiromantes haematocheir (De Haan,
1833) (Naruse & Ng, in press)
{10} Ng (2002e) described a number of new
cavernicolous Sesarmoides from the Indo-West Pacific
and commented that the genus could be separated into two
groups. Davie & Ng (2007) subsequently found more
characters, and established a new genus, Karstama, for the
cave-dwelling species previously assigned to Sesarmoides.
{15} The possible conspecificity of Sesarma (Sesarma)
gordoni Shen, 1935, and Sesarma minuta De Man, 1887, has
been discussed several times (see Ng et al., 2001; Davie,
2002) but a soon to be completed revision of Nanosesarma
by P. J. F. Davie indicates that the two are synonymous.
{11} Sesarma trapezoidea H. Milne Edwards, 1837 (at
present in Labuanium, sensu Serène & Soh, 1970) and
Sesarma weberi De Man, 1892 (at present in Sesarmops,
sensu Serène & Soh, 1970) should be placed in the same
genus as they share a suite of cheliped, gonopodal and
larval features (P. K. L. Ng, ongoing study) (see Jeng et
al., 2003).
{16} Sesarma (Episesarma) pontianacensis De Man,
1895, was referred to Nanosesarma by Tweedie (1950)
but a soon to be completed revision of the genus by P. J.
F. Davie indicates that it belongs to its own monotypic
genus. It is retained in Nanosesarma pending publication.
{12} Muradium Serène & Soh, 1970 (type species Cancer
tetragonus Fabricius, 1798) and Tiomanum Serène & Soh,
1970 (type species Sesarma indica H. Milne Edwards,
1837) were originally established as subgenera of
Neoepisesarma Serène & Soh, 1970 (type species Sesarma
mederi H. Milne Edwards, 1853) (presently = Episesarma
De Man, 1895, type species Sesarma taeniolata Miers,
1877) by Serène & Soh (1970), and are here recognised as
genera for convenience. An ongoing revision of
Episesarma by P. J. F. Davie, however, indicates that all
{17} Ng et al. (2001), citing a study by A.-Y. Dai and her
colleagues on some Hong Kong sesarmids, noted that
Parasesarma acis Davie, 1993, was very likely to be a
junior subjective synonym of Parasesarma tripectinis
(Shen, 1940). In a separate study on some Irian Jayan
(Indonesia) species of Parasesarma, Rahayu & Ng (2005)
examined fresh material of P. tripectinis and confirmed
the two as conspecific.

THE RAFFLES BULLETIN OF ZOOLOGY 2008
{18} The two African species, Sesarma (Chiromantes)
alberti Rathbun, 1921, and Sesarma huzardi (Desmarest,
1825), are currently regarded as members of Perisesarma,
but a re-examination of material of these two taxa suggest
that they should be referred to a separate genus (P. J. F.
Davie, ongoing study).
{19} Sesarma crassimanum De Man, 1887, Sesarma
johorensis Tweedie, 1940, Sesarma moeschi De Man,
1888, and Pseudosesarma patshuni Soh, 1978, are
currently placed in Pseudosesarma (sensu Serène & Soh,
1970), but an ongoing revision of this genus by P. K. L.
Ng and C. D. Schubart (using morphological and
molecular data) shows that both species are congeneric
with Sesarma dehaani H. Milne Edwards, 1853 (now in
Chiromantes) (see point 5).
Fig. 163. Perisesarma indiarum, Singapore (photo: T. Naruse)
{20} Sesarma elongata A. Milne-Edwards, 1869, has been
included in Selatium in some literature (e.g. Hartnoll,
1975), without justification. This placement has now been
confirmed by C. D. Schubart and P. K. L. Ng using
morphological and molecular data sets. A new allied
genus and two new species of intertidal sesarmids from
Singapore and Taiwan are also to be described (Schubart
& Ng, in prep.).
{21} Sesarma sinense H. Milne Edwards, 1853, and
Grapsus (Pachysoma) intermedium De Haan, 1835, are
currently placed in Sesarmops (sensu Serène & Soh,
1970), but an ongoing revision by P. K. L. Ng and C. D.
Schubart (using morphological and molecular data) shows
that both species are congeneric with Sesarma dehaani H.
Milne Edwards, 1853 (now in Chiromantes) (see point 5).
Fig. 164. Metopaulias depressus, Jamaica (photo: Father A. J. S. Muñoz)
{22} The identity of Cyclograpsus tasmanicus Hombron &
Jacquinot, 1846, is uncertain, but we are confident that it is
not a species of Cyclograpsus as present conceived.
Campbell & Griffin (1966) left the matter of this species
unsettled, but were certain it was not from Tasmania. The
figures in Jacquinot & Lucas indicate it is probably a species
of sesarmid. Characters such as the entire lateral carapace
margin, a broad front which partially covers the antennae
and antennules, chelae which lack stridulatory ridges, a
cheliped dactylus which does not have dorsal tubercles, and
the very short third maxilliped exopod with a rudimentary
flagellum, suggest a species of Metasesarma. The type(s)
will need to checked to ascertain its identity (see Ng &
Davie, 1995; Ng & Schubart, 2003).
Fig. 165. Karstama boholano, Bohol, Philippines (photo: T. Y. Chan)
{23} The original description of Cyclograpsus lophopus
by Nobili (1905) was not accompanied by any illustration,
but suggests a rather unusual member of the genus. Tohru
Naruse and N. K. Ng have examined the holotype female
in the Paris Museum. It is clearly not a species of
Cyclograpsus or varunid but a sesarmid instead. A new
genus will need to be established for it at a later date.

Notes
{1} According to Manning & Holthuis (1981: 209), P.
fossulum Barnard, 1955, is "... certainly no Paracleistostoma and possibly not even an ocypodid". P. K. L.
Ng and C. G. S. Tan examined the holotype of P. fossulum
in the South African Museum (a female 5.0 × 3.5 mm,
catalogue number A10778, Delagoa Bay, South Africa), and
the species is unlikely to be a camptandriid. The specimen is
in poor condition but it is clear that the figures given in
Barnard (1955) are accurate. As Manning & Holthuis (1981)
have noted, the chelipeds are robust, unlike the small,
slender ones of all known camptandriid females. Also, the
third maxillipeds are set very wide apart, which is also not
found in any other camptandriids; Paratylodiplax
blephariskios has the closest to this condition with a
triangular gap between the third maxilliped ischia (Barnard,
1950). From the available evidence, P. fossulum is not a
camptandriid. The gaping third maxillipeds, setose
ambulatory articles, and the form of the chelae suggest that it
is most likely to be a species of Varunidae. Many varunids
have similar features, although the transversely rectangular
carapace with its transverse ridges, also immediately
distinguishes it from any known varunid. One genus,
Parapyxidognathus Ward, 1941, is atypical for a varunine in
that it has a broader than long carapace, and in some ways
resembles Paracleistostoma fossulum. In the form of its
carapace, P. fossulum also somewhat resembles the unusual
pinnotherid Asthenognathus gallardoi Serène & Soh, 1976
(see below).

{3} Asthenognathus gallardoi Serène & Soh, 1976, is a
very unusual species, and certainly cannot be retained in
the genus as it now stands. It is markedly different from
other members in the form of its carapace (with two
transverse ridges on the dorsal surface), and by having
normal third maxillipeds (P. J. F. Davie and P. K. L. Ng,
unpublished data). Indications are that it should be
referred to its own genus. Unfortunately, it is known only
from one female specimen. In some ways, this species
229
Ng et al.: Systema Brachyurorum Part I
resembles retroplumids in the form of the carapace but
differs in its relatively broader front and distinct last
pereiopod. It also bears a resemblance (especially the
carapace) to “Paracleistostoma” fossulum Barnard, 1955,
but the two are unlikely to be related as they have different
pereiopods and mouthparts (see Notes for P. fossulum). A
new species, close to A. gallardoi, was recently found in
western Thailand, but unfortunately, it is also represented
only by a female (Naruse & Clark, in press).
data, details of pigmentation, and form of the carapace and
gonopods (see also Mingkid et al., 2006). K. Sakai (2007)
synonymised both species arguing that neither colour nor
gonopodal differences were useful, although he did not
discuss any of the other characters, or explain the genetic
differences reported by the original authors. Having seen a
large series of Hemigrapsus penicillatus from East Asia as
well as specimens of H. tanakoi kindly passed to us by the
original authors, we do not agree with K. Sakai (2007).
“Although G1 and colour may not be good characters to
distinguish the two species, as varunid crabs are typically
highly variable in colour forms, and the G1 does not always
work for many genera. In the case of H. penicillatus and H.
tanakoi, there are enough differences in the form of the
infra-orbital ridge, proportions of the ambulatory legs, the
male telson, tip of the G1 and the female gonopore, to
warrant the separation of the two species.” (N. K. Ng, pers.
comm.). We here recognise them as separate. A possible
complication regarding the use of the names is the identity of
Brachynotus brevidigitatus Yokoya, 1928, a species long
regarded as a junior synonym of H. penicillatus, but if
synonymous with H. tanakoi would become the older
available name.
{4} Metaplax crenulata (Gerstaecker, 1856) is an atypical
member of the genus as it now stands, and likely should
be referred to its own genus. In any case, the genus
Metaplax is currently being revised (Yang et al., in prep.).
{5} K. Sakai, Türkay & Yang (2006) established
Parahelice as a subgenus of Pseudohelice K. Sakai,
Türkay & Yang, 2006, but the differences described
appear strong enough to simply recognise it as a distinct
genus, as is done here.
{6} Gaetice has often been attributed to “Gistel, 1835” but
this seems to be an error that has been perpetuated as we can
find no such publication. Gistel (1848: x) was the first to
realise that the name Ocypode (Platynotus) De Haan, 1835,
was pre-occupied by a beetle genus, Platynotus Fabricius,
1801, and provided a replacement name, Goetice. Gistel did
not explain the origins of his name but it was clearly spelt
“Goetice”. Stimpson (1858: 50), apparently unaware of
Gistel’s (1838) action, proposed another replacement name,
Platygrapsus for Platynotus. Mary Rathbun, in a footnote in
Stimpson (1907: 128), noted that Platygrapsus had been
preceded by “Gætice Gistel”, but did not explain why the
spelling was changed. Tesch (1918a: 84, footnote) followed
Rathbun, and the name “Gaetice” has been used by almost
all subsequent authors. The type species, Gaetice depressus,
is a very common intertidal crab in East Asia, and the name
is used widely in reference texts, guides and other
publications (e.g. see references in Sakai, 1976; Dai et al.,
1986; Dai & Yang, 1991; Ng et al., 2001). While Goetice
Gistel, 1848, is clearly the oldest available name, Rathbun’s
unjustified emended spelling, Gaetice, is the one in common
use. The Code has a clause which states that “when an
unjustified emendation is in prevailing usage and is
attributed to the original author and date it is deemed to be a
justified emendation.” (Article 33.2.3.1). We here invoke
this Article to keep the name Gaetice as spelt by Rathbun (in
Stimpson, 1907) but attributed to Gistel (1848). Only two
species are now recognised in Gaetice, G. depressus (De
Haan, 1835) and G. ungulatus Sakai, 1939, but on ongoing
revision by T. Naruse and N. K. Ng suggests that there are
more species.
{9} Dentoxanthus komodoensis was described from a reef
near the island of Komodo, Indonesia, by Serène (1971) on
the basis of one small female specimen. Ng & Števi
(1993) re-examined the specimen, and noted that, despite its
small size, it was mature. Serène (1971) believed that it was
related to eumedonines (Pilumnidae), with Števi & Ng
(1988) and Ng & Števi (1993) agreeing and suggesting it
resembled genera like Gonatonotus. Because of the many
differences with Denthoxanthus iranicus Stephensen, 1946
(the type of the genus), Ng & Števi (1993) established a
new genus, Otognathon, for Dentoxanthus komodoensis
Serène, 1971. Two of the authors, P. K. L. Ng and P. J. F.
Davie, together with N. K. Ng who recently completed a
revision of the Varunidae, re-examined the type specimen of
O. komodoensis (in the Zoological Reference Collection of
the Raffles Museum, Singapore), and we now believe that it
is not a pilumnoid but a varunid. There are some small
varunid genera allied to Pseudograpsus that live in reef
environments, and the females of these can be difficult to
classify. For example, the affinities of Scutumara Ng &
Nakasone, 1993, were not very clear until N. K. Ng &
Komai (2000) found the males and clearly showed that it
was a varunid. N. K. Ng and T. Komai are currently
describing a new genus and new species of small varunid
from Japan, that has a carapace similar to that of
Otognathon. The female abdomen, vulvae and third
maxillipeds of the female holotype of O. komodoensis are
very similar to Pseudograpsus and Scutumara, although its
ambulatory legs and chelipeds are atypical. Significantly, we
observed that the distal part of the fingers has a chitinous
edge (described by Ng & Števi (1993) as “blade-like”) – a
character present in many grapsoids but not known in
pilumnoids. Recently an undescribed species of Otognathon
was collected from the Ryukyu Islands. It is clearly a
grapsoid - the penis of the male of this species exits from
thoracic sternite 8 (i.e. it is a thoracotreme), the inner surface
of the chela is setose, the tips of the fingers have pectinated
tips, the G1 is strongly calcified and straight, etc. (N. K. Ng
{7} The generic position of Heterograpsus spinosus H.
Milne Edwards, 1853, needs to be re-examined. It is
currently in the genus Brachynotus (see Davie, 2002) but
it also has affinities with Heterograpsus. This matter is
currently under study by N. K. Ng.
{8} Hemigrapsus tanakoi Asakura & Watanabe, 2005, was
described as a sibling species of Hemigrapsus penicillatus
(De Haan, 1835), distinguished primarily by biochemical
230
THE RAFFLES BULLETIN OF ZOOLOGY 2008
& T. Naruse, unpublished data). In view of all this evidence,
we are now confident that Otognathon is a varunid.
{10} Gaetice americanus Rathbun, 1923, is clearly not a
member of the genus Gaetice sensu stricto, and not even
part of the Gaeticinae. It is closer to Hemigrapsus and is
here transferred to a new genus, Pseudogaetice, in the
Varuninae (Davie & N. K. Ng, 2007).
{11} Pseudograpsus is now being revised by N. K. Ng. P.
K. L. Ng & Nakasone (1993) and N. K. Ng et al. (2002)
have already indicated that at least two or three genera can
be recognised.
{12} Ptychognathus is being revised by N. K. Ng and P.
K. L. Ng. Several groups of species are recognisable, and
new genera will be established for them.

tunnel, hence its dark colour (photo: P. Ng)
{13} Utica can be easily divided into two groups, one with
a distinct tranverse ridge on the carapace dorsal surface,
and another without (P. J. F. Davie and N. K. Ng).
{14} Henri Milne Edwards (1837: 77), in discussing his new
species, Sesarma pisonii H. Milne Edwards, 1837,
commented that Herbst in his first volume, on page 126 and
plate 37, had described a species “Cancer hispanus”, that
was probably the same as his species. The page H. Milne
Edwards cited was incorrect, it is 150 and not 126. E.
Desmarest (1858: 26) in his synopsis of Sesarma also
commented that Cancer hispanus is a problem. Herbst
(1794: 150, pl. 37 fig. 1) had described and figured Cancer
hispanus, supposedly from rivers in Spain. No
measurements were provided. From his description and
figure, we have difficulty identifying the animal. It is
certainly not the west Atlantic Aratus pisonii which has very
different carapace features. Cancer hispanus resembles
varunids in the general form of its carapace and keeled
chelae, but its front is relatively narrow, and we know of no
genus with which it can be identified. It also superficially
resembles a male pinnotherid, although the figured stalked
eyes seem too long. There are no known crabs from Spain or
the eastern Atlantic that fit the animal Herbst described. Of
course, it is also likely that Herbst’s locality and habitat data
are wrong. The specimen(s) in question are no longer extant
and are not listed in K. Sakai (1999). For the moment, we
regard it as incerta sedis in the Varunidae.

Serène (1974: 64) noted "... it is possible that eriophorum
is a Leipocten or Baruna ...", although Nobili’s (1903)
comparisons with Paracleistostoma suggests otherwise.
Harminto & Ng (1989) did not consider this species in his
study of Baruna. Through the courtesy of Giovanni Balma
of the University of Turin, the first author managed to
examine the holotype of Paracleistostoma eriophorum
Nobili, 1903. Studies with C. G. S. Tan show that it is a
senior synonym of Paracleistostoma tweediei Tan &
Humpherys, 1995 (material examined: Paracleistostoma

Notes
There is also a nomenclatural issue with Paracleistostoma
tweediei C. G. S. Tan & Humpherys, 1995, and
Paracleistostoma tweediei C. G. S. Tan & Ng, 1995. Both
are objective synonyms as they are based on the same
holotype. The problem arose because C. G. S. Tan and P. K.
L. Ng originally intended to publish the new species, and the
paper was prepared for a regional symposium in 1994 (Tan
& Ng, 1995). At the same time, P. J. F. Davie and A.
Humpherys had independently also discovered the species.
As it was clear that the two taxa in question were
conspecific, P. J. F. Davie and P. K. L. Ng left it to C. G. S.
Tan and A. Humpherys to finish the new species description
on their own (Tan & Humpherys, 1995). In early 1995, P. K.
L. Ng asked the editors of the symposium volume to have
the paragraph on the new Paracleistostoma in their paper
deleted, but although they agreed, the changes were not
made, no proofs were sent, and the volume was published in
1995 with the problem paragraph still intact. This mistake
nevertheless validates P. tweediei C. G. S. Tan & Ng, 1995.
In any case, the symposium article came out later than the
paper in the Raffles Bulletin of Zoology. Since the
symposium volume did not have a publication date, under
the Code, it should be regarded as published on 31
December 2005. This gives P. tweediei C. G. S. Tan &
Humpherys, 1995, priority over P. tweediei C. G. S. Tan &
Ng, 1995.
{1} Cleistostoma edwardsii MacLeay, 1838, was referred to
Paratylodiplax Serène, 1974, an action followed by
Manning & Holthuis (1981) in their important review of the
family. Tylodiplax indica Alcock, 1900, has been left in the
genus without change since its description. The first author
has examined specimens of both species and they are
different from all other congeners. They will be placed in
their own monotypic genera (Tan & Ng, in prep.). Reexamination of material of Cleistostoma dilatatum (De
Haan, 1833) and Cleistostoma kuwaitense Jones & Clayton,
1983, type species of Cleistostoma De Haan, 1833, and
Leptochryseus Al-Khayat & Jones, 1996, respectively, have
shown that the two genera are synonyms (Tan & Ng, in
prep.). Tan & Ng (in prep.) also show that Deiratonotus
Manning & Holthuis, 1981, is also heterogeneous with two
distinct groups, and the one containing Paracleistostoma
japonicum Sakai, 1983, belongs to a new genus (see Sakai,
1934, 1983). They also concur with Kawane et al. (2005)
who argue that Deiratonotus japonicum (Sakai, 1934), is a
senior synonym of Deiratonotus tondensis Sakai, 1983.
{2} "Cleistostoma" mcneilli Ward, 1933, is not a species
of Cleistostoma, and although some workers have referred
it to Paracleistosoma it is also misplaced there. P. J. F.
Davie is currently revising the Australian camptandriids
and may place it in a new genus along with two other new
species indigeneous to Australia.
{3} The identity of Paracleistostoma eriophorum Nobili,
1903, has been uncertain as he did not provide a figure,
although the description was fairly detailed. Nonili (1903)
distinguished it from from P. depressum and P. cristatum
by its unusually tomentose ambulatory legs and the
presence of two carinae of long granules on the inferior
and superior margins of the outer surface of the cheliped
palm. Nobili (1903) mentioned that the posterior carapace,
including the median branchial and area around the
intestinal region bears thick, short felt-like tomentum and
the ambulatory legs are covered with long, woolly setae.
He described the dactyli of the ambulatory legs as bearing

Notes
{1} Ilyoplax is being revised by P. J. F. Davie and
Takeharu Kosuge and Dioxippe, long synonymised with
Ilyoplax, will need to be resurrected. New genera will also
be established for several other species.
{2} In an ongoing study of the Australian Scopimera by
Michael Türkay with P. J. F. Davie, the necessity to split
Scopimera into at least two genera is apparent.
{3} The position of Shenius anomalus (Shen, 1935) has not
been settled. Shen (1935: 32, Fig. 9A, B) originally placed it
in Camptandrium because the carapace and legs are similar,
but his figures of the suborbital margin, male abdomen and
235
Ng et al.: Systema Brachyurorum Part I
G1 (Shen, 1935: Fig. 8B, 9C, D) do not indicate a close
relationship. Realising this, Serène (1971) established a new
genus, Shenius, for it. Serène (1974) then transferred Shenius
to Dotillinae Stimpson, 1858 (present Dotillidae), albeit with
some doubt, probably because the carapace and pereiopod
structures of Shenius, when compared to dotillids, are
extremely different. Mannning & Holthuis (1981) agreed
that Shenius was not a camptandriid. In an unpublished
thesis, Harminto (1988) re-examined Shenius (with the first
author) and agreed with Serène (1974) about its relationships
to the Dotillidae. As in dotillids the male abdomen has all
segments freely articulating, the G1 is slender and bent at the
tip, and the mouthparts and orbital regions are of the same
form. The different carapace and periopod features,
however, suggest that it should be placed in its own
subfamily, and a manuscript proposing this is being finished
by P. K. L. Ng and Paul Clark (Ng & Clark, in prep.).
Shenius is common in several parts of Singapore and P. K.
L. Ng has provided larvae to Paul Clark and Jose Cuesta.
The first zoea are very similar to known dotillids. Christoph
Schubart has also sequenced its DNA and its affinities are
clearly with the Dotillidae.

{4} Peter K. L. Ng and C. G. S. Tan have examined the type
of Paracleistostoma dentatum Tesch, 1918a, and the species
is not a camptandriid. The third maxillipeds are broad, with
the merus and ischium almost equally long, and the front is
narrow, being slightly less than half the width of the orbit.
Unfortunately the only known specimen is the holotype
female (6.2 × 3.3 mm, Amsterdam Museum De.102.997,
coll. from Saleyer Island off southern Celebes (Sulawesi) in
Indonesia by M. Weber (7–8 May 1899, Siboga
Expedition)). Therefore the taxonomically crucial male
abdominal and G1 characters are unknown. It is likely to be
a species of Dotillinae, probably affiliated with Ilyoplax
Stimpson, 1858. It is interesting to note that all the
ambulatory legs have a fringe of longish setae on the inner
edge of the dactyli. If it were to be transferred to Ilyoplax,
then it would become a senior homonym of Ilyoplax dentata
Ward, 1933, and the latter name would need to be replaced.
{5} Xenophthalmus duplociliatus Sluiter, 1881, was
described from Java, Indonesia, and its identity has been
problematic. Tesch (1918: 271) argued that it was not a
Xenophthalmus species or pinnotherid but left its position
unresolved. The description by Sluiter (1881: 163) makes
it clear that this is likely to be a dotillid, perhaps a Dotilla
species (see Point 9 in Notes for Pinnotheridae).

Notes
{1} The taxonomic position of Ilyograpsus has been a
problem. Because of an obviously “grapsoid-like” external
appearance, it has long been associated with that family or
its allies. Fukuda (1978) first noted that it was more likely
to be an ocypodoid instead on the basis of zoeal evidence;
this was supported by a later study by Cuesta et al. (1997).
Examination of fresh specimens confirms this supposition.
In some ways, Ilyograpsus species resemble camptandriids (which some have been confused with in the
past, see C. G. S. Tan & Ng, 1999), but the abdomen and
gonopods ally them clearly with the macrophthalmids.
Števi (2005) recognised the family Macrophthalmidae
but despite not recognizing any subfamilies within,
nevertheless established a new tribe, Ilyograpsini, together
with the tribe Macrophthalmini. In the present
classification, his Ilyograpsini is regarded as a subfamily.

{3} The taxonomy of the various subgenera of
Macrophthalmus is less than satisfactory. Some such as
Chaenostoma, Euplax and Venitus appear to be distinct
and probably deserve to be treated as good genera. Barnes
(1970, 1977), provided a valuable baseline but a modern
revision is urgently needed.
{4} Barnes (1957) proposed a new name for this
subgenus, Macrophthalmus (Mopsocarcinus) (type species
Macrophthalmus boscii Audouin, 1826), apparently
unaware that there was an earlier name, Chaenostoma
Stimpson, 1858 (type species Chaenostoma orientale
Stimpson, 1858). Since Chaenostoma orientale Stimpson,
1858, is now regarded as a junior synonym of
Macrophthalmus boscii Audouin, 1826, the name
Chaenostoma Stimpson, 1858, must have priority as the
subgeneric name (see Stimpson, 1858b; Ng et al., 2001).
{5} Euplax H. Milne Edwards, 1852, synonymised under
Macrophthalmus (Venitus) Barnes, 1967, by Barnes (1977)
(see also Barnes, 1966), was regarded as a good subgenus by
Mendoza & Ng (2007). In any case, if Euplax and Venitus
are regarded as synonyms, Euplax has priority, not Venitus,
as believed by Barnes (1977). This was first pointed out by
Karasawa & Matsuoka (1992).

{6} Hemiplax hirtipes Heller, 1865, is now regarded as a
junior synonym of Macrophthalmus (Hemiplax) hirtipes
(Jacquinot, in Hombron & Jacquinot, 1846). If Heller's
species was ever to be referred to Macrophthalmus sensu
stricto and regarded as a distinct species, a replacement
would become necessary.
{7} These species of Tritodynamia have been previously
placed in the Pinnotheridae, but most have features more
typical of macrophthalmid crabs. Their distinctive
appearance, and a number of apomorphic characters warrant
238

their own subfamily. However, two species, T. horvathi and
T. intermedia, appear to be abberant within the genus,
showing varunid rather than macrophthalmid affinities. This
is the subject of an ongoing revision by P.J.F. Davie and N.
K. Ng. If they are to be removed from Tritodynamia, then
Tritodynamea Balss, 1922, is available to receive them. See
point 1 in Notes on Pinnotheridae.

has ongoing work revising this family, and numerous new

Notes
{1} The identities of many species of Ocypode are still
unclear; a revision is currently underway by Michael
Türkay (Senckenberg Museum) and Katsushi Sakai
(Kumamoto University, Japan).
{2} The identity of Cancer caninus Herbst, 1782 (p.78) is
a problem. Herbst (1782: 78) cited and repeated the
description of Rumphius (1705) from Indonesia. However
the description is peculiar and seems to be a composite of
two different species. Holthuis suggested to Beekman
(1999: 400) that one might be a species of Cardisoma
(Gecarcinidae), and the other the well known ocypodid
Ocypode ceratophthalmus. From the description
(translated by Beekman, 1999: 33), the gecarcinid is either
Cardisoma carnifex or Discoplax hirtipes, but the
description of Ocypode is more precise and we agree that
it must be O. ceratophthalmus. There are no types and no
figures (see also K. Sakai, 1999), but the name is available
under the Code. We hereby act as first revisor and select
the Ocypode part of the description to represent Cancer
caninus Herbst, 1782. As such, Cancer caninus Herbst,
1782, becomes a junior subjective synonym of Cancer
ceratophthalmus Pallas, 1772.

{3} The identity of Ocypode rhombea Fabricius, 1798, is
not possible to ascertain as the sole remaining presumed
type specimen in the ZMUC is a juvenile, and in poor
condition. We follow convention in regarding it as a junior
subjective synonym of Ocypode quadratus (Fabricius,
1787).
{4} Uca is a major problem despite the major revisions
of Bott (1973) and Crane (1975). Most modern workers
refuse to use the subgeneric systems proposed by these
authors, or recognise any of them as genera. Despite
this, most recognise that Uca sensu lato is markedly
heterogeneous. Rosenberg (2001) supported recognition
of most of Crane’s (1975) subgenera, with support also
for elevation to full genera (see also Rosenberg, 2000).
Studies on the gastric mill by S. L. Yang (pers. comm.)
also agree. Ongoing work by Shih Hsi-Te (Taichung
Museum, Taiwan) suggests that at least one more
supraspecific group can also be recognised. Crane’s
(1975) subgeneric grouping is more coherent and robust
than that of Bott (1973), although some species will
need to be reallocated. In the most recent reappraisal,
Beinlich & von Hagen (2006) proposed a revised system
of classification, recognising some supraspecific taxa
and synonymising others. They also make a de facto
selection of one name over another when the names
were published in the same paper (ICZN, Article
24.2.2). To this effect, they selected Latuca Bott, 1973,
over Mesuca Bott, 1973; and Paraleptuca Bott, 1973,
over Austruca Bott, 1973. Several Uca species can still
not be confidently identified, so cannot yet be
subgenerically allocated. These taxa were discussed in
detail by Crane (1975), and should be resolvable with
future study. They are here listed as incertae sedis. It
seems unlikely that the subgeneric and generic system in
Uca will be settled until a new, thorough taxonomic

treatment is undertaken, using not only traditional

{5} With regards to Gelasimus marionis, Desmarest
(1823: 243) noted: “Gélasime de Marion": "Cette espèce...
est de Manille. Elle m'a été communiquée par M. Marion
de Procé de Nantes, à qui je la dédie" (see also Desmarest,
1825: 125). Gelasimus marionis Desmarest, 1823, is
currently considered a junior synonym of Uca vocans
(Linnaeus, 1758). Unfortunately the type is believed lost.
None of Marion de Procé’s material appears to have
survived, but we do know that at least some material
arrived back in France (see also de Procé, 1822), because
he clearly gave a fiddler crab to Desmarest (1823)!

(see Huang et al., 1998; photo: P. Ng)
{6} The name “Goneplace luisant”, followed by the Latin
name Goneplax nitida, was first used for a fossil crab
(unknown origin) in Desmarest (1817: 505), but he later
(Desmarest, 1822: 106, pl. 8, figs. 7, 8) named it
“Gelasima nitida (Gélasime luisante”. Henri Milne
Edwards (1837: 55, footnote) accepted the synonymy of
“Gonoplace luisante Desmarest, 1817, with Gelasimus
nitidus Desmarest, 1822. Dana (1852a) subsequently
established a new species, Uca nitidus from Fiji,
apparently unaware of Desmarest’s action. That U. nitidus
is a Dana species (without reference to Desmarest’s taxa)
has been followed by subsequent workers like H. Milne
Edwards (1852) and Crane (1975: 89), with the latter
accepting it as a junior synonym of Uca vocans. The
identity of Desmarest’s (1817, 1822) species is difficult to
ascertain, and until it can be shown that it is synonymous
with another known taxon, we recognise it as distinct for
the time being. Accepting both, Gelasimus nitidus
Desmarest, 1822, and Gelasimus nitidus Dana, 1851b,
causes a problem of homonomy, but since the latter is a
junior synonym of U. vocans, there is no immediate
problem. If both are recognised as valid Uca species, then
a replacement will be needed for Dana’s name.

junior synonym, Uca salsisitus Oliveira, 1939, see
Tavares & Braga de Mendonça (2003).
{8} Crane (1975: 323) gives a detailed explanation of the
serious problems relating to Gelasimus forceps H. Milne
Edwards, 1837. The type in the Paris Museum is a
composite of a female body and a large male clela. Crane
could not determine the identity of the female body, but
considered the chela to very likely be from Uca lactea (De
Haan, 1835). She regarded the identity of this species as
unresolved. We here designate the chela identified as
belonging to Uca lactea, as the lectotype of Gelasimus
forceps H. Milne Edwards, 1837. This action makes both
names synonyms and resolves the impasse with H. Milne
Edwards’ taxon.

Remarks. – The phylogenetic affinities of Ucides
Rathbun, 1897, have been uncertain for many years. The
type species U. cordatus (Linnaeus, 1763) was for a long
time placed in the Gecarcinidae because of its superficial
similarities with genera like Cardisoma. Chace & Hobbs
(1969) transferred it to the Ocypodidae. Türkay (1983b)
supported this action and further placed it in the subfamily
Heloecinae H. Milne Edwards, 1852. We have been
studying its affinities for several years and were preparing
to recognise Ucides as belonging to a distinct family when
Števi (2005: 131) established the subfamily Ucidinae in
the Ocypodidae.
Notes
{1} Linnaeus (1767) named a species Cancer uca, which
was later realised to be the same as one he had named
earlier in 1763 as Cancer cordatus. The vernacular name
“uçá” is one of the native Brazilian names employed by
the famous naturalist G. Marcgraf in his Historia
Naturalis Brasiliae (1648) and introduced into the
zoological nomenclature, as Cancer uca, a species
currently known as Ucides cordatus (see Tavares 1993).
The name “uca” is today closely associated with the
fiddler crabs of the genus Uca Leach, 1814, the type
species being Uca major Herbst, 1782 (Opinion 712). Uca
Latreille, 1819 (a junior homonym of Uca Leach, 1814)
on the other hand, has Cancer uca Linnaeus, 1767, as the
type species (Opinion 712). Cancer cordatus Linnaeus,
1763, and Cancer uca Linnaeus, 1767, are not fiddler
crabs. To avoid confusion, Rathbun (1897), proposed
Ucides as a replacement name for Uca Latreille, 1819, but
chose Cancer cordatus Linnaeus, 1763, as the type
species, because she realised it was a senior synonym of
Cancer uca Linnaeus, 1767. In that same year, Ortmann
(1897) independently proposed his own replacement
name, Oedipleura, and since Ortmann did not specify, its
type species is automatically Cancer uca Linnaeus, 1767,
the same as that for Uca Latreille, 1819. This is the reason
why Ucides Rathbun, 1897, and Oedipleura Ortmann,
1897, although both proposed as replacement names for
Uca Latreille, 1819, have different but synonymous names
for their type species.
We disagree with the inclusion of Ucides in the
Ocypodidae sensu stricto. It has a suite of significant
apomorphies that suggest separate family ranking, e.g.
carapace features, corneal structure, male abdominal
segmentation, absence of setal tufts between the bases of
the pereiopods, and the efferent branchial channels not
being closed by the third maxillipeds anteriorly (Davie &
Ng, in prep.).

however, have male abdominal segments 2 and 3 fused,
and their G1 is strongly recurved (see Ng, 1998; C. G. S.
Tan & Ng, 1999; Davie, 2002).
FAMILY XENOPHTHALMIDAE
STIMPSON, 1858
Xenophthalmidae Stimpson, 1858
However, despite a resemblance to the dotillids, the
absence of an epistome, the swollen pterygostomial
regions, upturned front, the strongly reduced eyes, slit-like
orbits and pilose legs with short spatuliform dactyli (see
Rathbun, 1931; Sankarankutty, 1969; Takeda & Miyake,
1970; Serène & Umali, 1972), make the placement of
these genera in the Dotillidae untenable. As such, it is best
to recognise a separate family for Xenophthalmus,
Anomalifrons and Neoxenophthalmus. Because the
affinities of these genera are clearly with the Dotillidae
and we here refer the Xenophthalmidae to the
Ocypodoidea.
Remarks. – The Xenophthalminae Stimpson, 1858, has
traditionally been placed in the Pinnotheridae as a distinct
subfamily (see Schmidtt et al., 1973), even though all its
members are free-living. However, Serène & Umali
(1972: 84) had argued that it cannot be retained in the
Pinnotheridae and should be recognised as a separate
family. They comment that “in these three genera
[Xenophthalmus, Neoxenophthalmus and Anomalifrons],
the merus and the ischium of the third maxilliped are
clearly separated, this particular character shows that the
subfamilies Xenophthalminae and Anomalifrontinae must
be excluded from the family Pinnotheridae and the family
Xenophthalmidae Stimpson (1858) restored for them. This
family is mainly characterized by the pronounced swelling
of the pterygostomial region. The pseudo antero-lateral
border of the carapace corresponds to the pterygostomian
rim. The true antero-lateral border of the carapace is only
faintly indicated by a feeble rim joining the posterior limit
of the orbit to a notch corresponding to the junction of the
pterygostomian rim with the lateral border of the
carapace.” (Serène & Umali, 1972: 84). Serène & Umali
also noted that the two subfamilies can be differentiated
by the form of the epistome and buccal cavern (without
trace of an epistome, with the anterior part of the buccal
cavern extending to the base of the antennular fossa in
Xenophthalminae, versus with a narrow epistome and the
anterior part of buccal cavern is normal in
Anomalifrontinae). However, in the heading of the page
discussing these three genera, Serène & Umali (1972: 84)
still used the subfamily rank, “Xenophthalminae” (but
under the family Grapsidae) and this may have contributed
to workers not realizing that it had been recognised as a
distinct family by them.
As to the two subfamilies recognised by Serène & Umali
(1972), Xenophthalminae and Anomalifrontinae, we are
unsure if this is really warranted. The differences which
have been discussed but they are not substantial and it may
be better to classify all three genera in one family without
subfamilies. This matter is now being examined in detail
by T. Naruse, P. Clark and P. K. L. Ng. For the moment,
we keep the system recommended by Serène & Umali
(1972).
One species previously referred to Xenophthalmus, X.
duplociliatus Sluiter, 1881, is almost certainly a true
dotillid (see Tesch, 1918: 271), and is referred there (see
point 5 in Notes of Dotillidae).
Xenophthalmus pinnotheroides lives in soft mud in
estuarine areas outside or near mangroves and can be
collected in depths of up to 10 metres by grabs or trawls.
In Peninsular Malaysia, when present, it can be found in
large numbers (A. Sasekumar, pers. comm.). It is not
known to be associated with any animals.
Števi (2005: 118) followed Serène & Umali (1972) in
recognising the Xenophthalmidae, with two subfamilies,
Xenophthalminae Stimpson, 1858, and Anomalifrontinae
Rathbun, 1931, but without further comment except to say
that it was “Heterotremata (?) incertae sedis”.

Peter K. L. Ng, Tohru Naruse and Paul F. Clark
(unpublished data) examined many specimens of
Xenophthalmus
pinnotheroides,
Neoxenophthalmus
obscurus and Anomalifrons lightana from Malaysia and
Thailand in the the Raffles Museum of Biodiversity
Research (Singapore) and The Natural History Museum
(London). We confirm that all three genera are clearly
thoracotremes. In the form of their medially constricted
male abdomens which have all segments free, the three
genera closely resemble many dotillids. The G1 is slender,
straight and not heavily chitinised, and also resembles
those of dotillids. The same is true of their third
maxillipeds which are similar in form to those of dotillids
or camptandriids. The chelae resemble those of camptandriids, with the chela relatively delicate, and the distal half
of the cutting edge of the dactylus armed with a low tooth
(see Rathbun, 1931; Sankarakutty, 1969; Takeda &
Miyake, 1970; Serène & Umali, 1972). Camptandriids,

third joint”. One cannot help thinking that WHITE
mistook the (bifurcated) pleopod of the , eaching
beyond the 3rd segment, for this “ciliated process”, for in
reality the abdomen of the does not show any
prominences on its exposed surface or on its borders.”
The description suggests that “Xenophthalmus
duplociliatus” is more likely to be a species of dotillid.
Interestingly, members of the genus Dotilla have a row
of setae across the abdomen as described by Sluiter
(1881: 163). We agree with Tesch (1918) that it is not a
Xenophthalmus species and we here refer it to the
Dotillidae as an incerta sedis.
Notes
{1} Xenophthalmus garthii Sankarankutty, 1969, must be
referred to Neoxenophthalmus Serène & Umali, 1972. It
has a G1 in which the distal part is drawn out into a
slender process (versus straight and simple in
Xenophthalmus) and the orbits and eyes are positioned
obliquely (versus parallel in Xenophthalmus). As both
species, N. obscurus Henderson, 1893, and N. garthii were
described from India, and the differences mentioned by
Sakarankutty (1969) do not appear to be substantial, it is
also possible that both are synonymous. Until more
specimens can be examined, we keep them as separate.
{2} Schmidtt et al. (1973: 99) recognised four species in
Xenophthalmus, but one species is clearly not a member
of this genus or even family. Xenophthalmus
duplociliatus Sluiter, 1881, was described from Tanjung
Priok in Java, and has not been reported since. The
description is brief but there are enough details to
suggest it is not a Xenophthalmus species or a
pinnotherid (see also Serène & Umali, 1972) but a
dotillid instead. Tesch (1918: 271) comments: “A third
species is X. duplociliatus Sluiter 1). This species,
according to the description, resembles the type species,
but the chelipeds are much stronger, broadly-flattened
and “lepelvormig gebogen” (shaped like a spoon);
besides the under surface of the posterior legs is brightly
red, and the 3rd and 4th segments of the abdomen of the
is provided with a transverse row of long hairs.
SLUITER [1881] says that WHITE [1846] mentions the
presence of bristles at the 3rd segment of the abdomen of
the , but the latter author’s words on this subject are:

Notes
{1} In the modern classification (e.g. see Schmitt et al.,
1973), members of the Asthenognathinae (with four
genera: Asthenognathus, Tritodynamia, Aphanodactylus
and Voeltzkowia) are among the more peculiar members
of the family Pinnotheridae, a group already known for
having many unusual taxa. Števi (2005) raised them to
family level within the Grapsoidea without much

Ng et al.: Systema Brachyurorum Part I
Tritodynamia, Tritodynamea and Asthenognathus is now
being revised by P. J. F. Davie and N. K. Ng, and the
problems discussed above will be elaborated on later.
discussion, while Cuesta et al. (2005), in an abstract,
suggested a close relationship with the Varunidae after
looking at the molecular data for several species.
Certainly, the general morphology of most of the
asthenognathine species has “grapsoid tendencies”,
including the tendency of some to swarm like some
varunids when they are at the megalopal stage (e.g.
Tritodynamia horvathi, see Otani et al., 1996; Matsuo,
1998, 1999). The best known varunid that does this is
Varuna litterata (see Connell & Robertson, 1986; Mana,
1988; Ryan & Choy, 1990). Examination of specimens
of Asthenognathus, Tritodynamia and Aphanodactylus at
our disposal revealed an interesting pattern.
Asthenognathus is a varunid in almost all ways (e.g.
form of the thoracic sternum and penial structure,
abdomen, gonopods and general form of the
pereiopods), and should be placed in the Varunidae.
There appear to be two groups of Tritodynamia. One
group, with eight species (including the type species),
has all the characters of macrophthalmids, and can
easily be accommodated in that family. None are known
to swarm like varunids. On the other hand, the second
group, with just two species (including T. horvathi),
shows varunid relationships. This is currently under
study by P. J. F. Davie and N. K. Ng. If the genus is to
be split, then through a nomenclatural error on the part
of Balss (1922b), a new name would not be needed.
Balss (1922b) commented that the type species of
Tritodynamia Ortmann, 1894, Tritodynamia japonica
Ortmann, 1894, was a synonym of Asthenognathus
inaequipes Stimpson, 1858, the type species of
Asthenognathus Stimpson, 1858. Both genera thus
became synonyms, with Asthenognathus having priority.
However, Balss (1922b) recognised a group which he
thought were real “Tritodynamia” as identified up to
that time, and to conserve the concept as well as the
name as much as possible, he proposed a new name for
them, Tritodynamea Balss, 1922, and designated
Tritodynamia horvathi Nobili, 1905, as the type species.
Of couse, in this instance, Balss (1922b) was wrong, and
Asthenognathus inaequipes and Tritodynamia japonica
are not synonyms, and neither were Asthenognathus and
Tritodynamia; and Tritodynamea Balss, 1922, became
an unneccesary though available name (see Schmitt et
al., 1973). Tritodynamia Ortmann, 1894, sensu lato is
here placed in the Macrophthalmidae as a separate
subfamily, the Tritodynamiinae Števi, 2005. Otani &
Muraoka (1990) compared the larvae of Tritodynamia
horvathi
Tritodynamia)
with
the
larvae
of
Asthenognathus japonicus described by Terada (1987)
and while there are differences in the structure of the
antennule, telson, abdomen and maxilla; the significance
of these differences will have to be weighed against
other varunids when more is known. Certainly, they do
not appear to be family-level differences (see Jeng et al.,
2004). Interestingly, in a preliminary study, Cuesta et al.
(2005) had larval and DNA datasets for several
asthenognathids, and suggested their affinities are with
varunids. They also noted that at least one species of
Pseudopinnixa, P. carinatus, was also allied to varunids.
For the moment, we retain Pseudopinnixa in the
Pinnotheridae but clearly, its position needs reappraisal.
These changes leave two genera “in limbo”,
Aphanodactylus Tesch, 1918b, and Voeltzkowia Lenz,
1905. Aphanodactylus appears to be a typical pinnotherid
in most ways, but is peculiar in having almost normal third
maxillipeds (see Konishi & Noda, 1999). We are unsure
about the status of Voeltzkowia. It was described by Lenz
(1905) on a single partially damaged female from
Zanzibar, and has a particularly unusual carapace. P. K. L.
Ng is revising Aphanodactylus with S. T. Ahyong. So far,
while it clearly thoracotreme, its numerous anomalous
features seem to prevent its placement in any of the known
pinnotherid subfamilies, or even in any of the other
thoracotreme families. Aphanodactylus and Voeltzkowia
may need to be referred to their own families when these
studies are completed.
{2} In establishing Pseudopinnixa, Ortmann (1894) did
not designate a type species, but Pseudopinnixa carinata
Ortmann, 1894, should be regarded as the type species by
monotypy. This is because the other species mentioned,
Pinnixa fischeri A. Milne-Edwards “scheint hierher su
gehören” [seems to belong here] is not a definite
assignment of this species to his new genus. In any case,
Pinnixa fischeri A. Milne-Edwards, 1867, is currently in
Tetrias.
{3} The case of the authorship of Arcotheres is a
challenge. The name was first used by Bürger (1895:
361) who wrote “Zur Aufstellung einer neuen Gattung
schienen mir Anfangs unbedingt Formen aufzufordern,
wie Pinnotheres palaensis, exiguus und nudifrons,
welche durch einen sechseckigen Cephalothorax und
längern Kralien ausgerüdtete hintere (3. und 4. Paar)
Gehbeine ausgezichnet sind. NAUCK, welcher sich
bereits mit den nämlichen Pinnotherinen beschäftigt und
verschiedene Aufzeichnungen über sie hinterlassen hat,
errichtete für sie das Genus Arcotheres, welches
indessen nur in unsern Katalogen und auf unsern
Etiketten figurirt. Ich habe dasselbe schliesslich nicht
angenommen, weil es der Uebergänge zwischen dem
runden Rückenschild der “typischen Pinnotheriden und
dem sechseckigen der Arcotheren viele und allmähliche
giebt und das Merkmal, welches die Gehbeine geben,
den Arten mit sechseckigen Rückenschild keinewegs
allein eigen ist und sie durchgehends charakterisirt”.
Translated, it basically means that Bürger noted that
three species, Pinnotheres palaensis, P. exiguus and P.
nudifrons, all of which were described in his paper,
appeared to differ in having more hexagonal carapaces
as well as longer third and fourth legs. Nauck, who had
studied the material, had left Bürger unpublished notes
that argue for establishing a genus called Arcotheres but
the name had only been used in unpublished catalogues
and labels thus far. Bürger, however, commented that he
did not accept Nauck’s new genus because of
transitional characters seen in other pinnotherids. The
name Arcotheres was not used again anywhere else in
Bürger’s (1895) paper. On the basis of Bürger’s
252
THE RAFFLES BULLETIN OF ZOOLOGY 2008
comments and actions, as noted above, he clearly treats
Arcotheres as a junior synonym of Pinnotheres. The
next time the name Arcotheres was used was in a list by
Rathbun (1918), who also treated it as a synonym of
Pinnotheres. Although Rathbun (1918) noted that the
type species was Pinnotheres palaensis Bürger, 1895,
this action is invalid because at that time, Arcotheres
was not an available name. Arcotheres was not used
again until Manning’s (1993b) reappraisal of the African
Pinnotheridae when he resurrected Arcotheres as valid
genus, but attributed it to Bürger (1895). Lipke Holthuis
(in litt to R. B. Manning), highlighted a serious
nomenclatural problem with Bürger’s name. This
pertained to Article 11.6 of the Code which treats names
first published as a synonym: “A name which when first
published in an available work was treated as a junior
synonym of a name then used as valid is not thereby
made available”. Article 11.6.1 elaborates “However, if
such a name published as a junior synonym had been
treated before 1961 as an available name and either
adopted as the name of the taxon or treated as a senior
homonym, it is made available thereby but dates from
its first publication as a synonym.” Of course, the name
Arcotheres, fails to fulfil Articles 11.6 and 11.6.1. Even
if the comments by Bürger (1895: 361) can be construed
as a diagnosis for the genus, the name Arcotheres
Bürger, 1895, is still not available under the Code.
Campos & Manning (2000) subsequently clarified the
matter of the authorship for Arcotheres, and noted that
the first valid use was by Manning (1993b), who also
validly selected the type species, Pinnotheres palaensis
Bürger, 1895.
etiam intra Ostream edulem L. majorem …” This wide
spectrum of hosts is confusing, but his detailed account
leaves no doubt he was referring to a species of
pinnotherid. There seems little doubt that both men were
referring to the same species, although de Wulfen makes
no reference to the animal being six-legged.
Schmitt et al. (1973: 74) referred both Scopoli’s and de
Wulfen’s records to Pinnotheres pisum (Linnaeus, 1767),
and wrote as follows: “Cancer Nutrix SCOPOLI, 1763,
Entomol. Carniolica: 410 (‘Pinnotheres pisum?’, fide
Nardo, 1869: 229; with footnote: ‘Gmelin lo riguarda
corne il C. minutus L.’ (the Gmelin identification is
considered untenable by Dr. F. A. Chace, Jr., USNM
[personal communication] because of the habitat
mentioned by Scopoli: ‘In Ost. eis Edulibus frequens, qua
nutrit, ut ait Populus’)” (Schmidtt et al., 1973: 73).
Apparently, Schmitt et al. (1973) did not have access to
Scopoli’s (1763) original paper, and relied on subsequent
literature. However, Schmitt et al. (1973) did not comment
on the fact that the name Cancer nutrix Scopoli, 1763, was
older than Cancer pisum Linnaeus, 1767.
While Scopoli’s (1763) name has long been associated
with Pinnotheres pisum, possibly because of geography,
it is important to note that both Cancer pinnotheres
Linnaeus, 1758 (at present in Nepinnotheres) and
Cancer pisum Linnaeus, 1767 (at present in
Pinnotheres) are both present in Italy. Moncharmont
(1979) and Grippa (1993) recorded both species from
“Golfo di Napoli” and “Arcipelago Toscano”
respectively (see also d’Udekem d’Acoz, 1999). While
there are indications that Nepinnotheres pinnotheres
prefers shells of the bivalve Pinna, while Pinnotheres
pisum prefers the oyster Ostrea, the relationship is by no
means exclusive, with the latter species having a very
wide host range (see review in d’Udekem d’Acoz, 1999:
243–244). While the two pinnotherid species are today
separated into two distinct genera (Manning, 1993b), the
descriptions of Linnaeus, Scopoli and de Wulfen are too
simple to allow us to separate them. It is just as possible
that Cancer nutrix Scopoli, 1763, is actually
synonymous with Nepinnotheres pinnotheres (Linnaeus,
1758), in which case there is no nomenclatural problem.
The absence of extant type specimens or material for
Linnaeus (1758, 1767), Scopoli (1763) and de Wulfen
(1791) makes the matter relatively easy to resolve with
appropriate neotype designations at a later date.
Probably the simplest and most parsimonious solution
would be to select a specimen from the Mediterranean
that is the simultaneous neotype of Cancer pinnotheres
Linnaeus, 1758, and Cancer nutrix Scopoli, 1763. This
would make both objective synonyms and resolve the
matter. This should be done by someone familiar with
the Mediterranean fauna and preferably using fresh
material.
{4} The pinnotherid collections described by Semper
(1880), Nauck (1880) and Bürger (1895), and particularly
by Bürger, are extremely important in the study of this
family. Ahyong & Ng (2007) re-examined their specimens
and clarified many long-standing nomenclatural and
taxonomic problems with the various species they
recognised.
{5} Pinnotheres is still heterogeneous despite the many
recent studies. Many of the species currently placed in
Pinnotheres belong elsewhere (many to Nepinnotheres),
especially considering Manning’s (1993b) restriction of
Pinnotheres to species with a third maxilliped dactylus
which articulates proximally on the propodus.
{6} Shen (1932) named Pinnotheres gordoni after Isabella
Gordon, a woman. The specific name must therefore be
altered to “gordonae”.
{7} Scopoli (1763: 410) named a species from the
Adriatic he called Cancer nutrix which lived inside shells
of the oyster Ostrea edulis. He commented that this was
based on a communication he received from de Wulfen.
His diagnosis noted that the species was common and the
animal was perhaps six-legged. Some years later, de
Wulfen (1791: 334) published his accounts of the Adriatic
fauna, and identified the same species as Cancer minutus,
but also referring to Scopoli’s “Cancer nutrix”. De Wulfen
commented that it “Frequens in Fucis, Spongilis, etc.,
{8} Cancer scopolinus Herbst, 1783, described from the
Adriatic Sea, has been neglected since its original
publication. In the description the carapace, female
abdomen, pleopods, and leg and cheliped features all
match a Pinnotheres (Herbst, 1783: 97). In fact, Herbst
253
Ng et al.: Systema Brachyurorum Part I
(1783) compares C. scopolinus to Cancer nutrix
Scopoli, 1763, which he says is close. The anomaly is
that he describes the specimen as having only six legs.
This suggests a hexapodid crab, which is not possible as
this family is not known from the Mediterranean. We
have to believe that Herbst probably had a Pinnotheres
specimen that had lost its last pair of small legs, not
uncommon for such small crabs. We here synonymise
Cancer scopolinus Herbst, 1783, under Cancer pisum
Linnaeus, 1767. No types appear to be extant (see K.
Sakai, 1999).
