Global checklist of pseudoscorpions (Arachnida) found in birds’ nests. - A compilation of the information on pseudoscorpions recorded from birds’ nests is presented. Species and families of birds, and specimens, species and families of pseudoscorpions involved worldwide are given. 14 families (63 genera with 85 species) of Pseudoscorpiones were found in birds’ nests, of which the Chernetidae is ranked first, with 22 genera and 35 species. Only 45 families of birds have been recorded as hosts worldwide, represented by a total of 98 species and a certain number of unidentified taxa. Geographical origin of these records reflects collecting efforts of individuals and gives no precise indication on the biological association between these two groups. Keywords: Ecology - behaviour - phoresy - host association. INTRODUCTION The arachnid order Pseudoscorpiones, commonly known as pseudoscorpions, false scorpions, or book scorpions, comprise about 3.3% of the described arachnids, with 3 385 known species (Harvey, 2009). Pseudoscorpions are small (typically less than 4 mm in length) predacious arachnids, feeding upon small invertebrates (e.g., mites, springtails, various flies and gnats, ants, insect larvae, and occasionally small caterpillars). The general ecology of the group is poorly known; the most intensive studies on tropical pseudoscorpions have been carried out in the Manaus Amazon region, under the guidance of the late Professor J. Adis (Plön, Germany) (e.g. Adis, 1979, 1992; Adis & Mahnert, 1985, 1990). They live in leaf litter, under rocks, in compost piles, under bark and in decaying wood, in caves, and in various invertebrate and vertebrate nests (Beier, 1948, 1963b; Weygoldt, 1969). No answer can be given to the question whether pseudoscorpions are arriving accidentally in the nests, if they are regular visitors, or if nests represent their favoured habitat. Beier (1948) had in his compilation enumerated 12 species found in birds’ nests or on birds, citing two species as living exclusively in this biotope: Diplotemnus insularis Chamberlin and Hesperochernes montanus Chamberlin, but all these conclusions were based on isolated findings. An exhaustive ecological study had been Manuscript accepted 20.07.2010 p. tuRienZo et al. 558 carried out by Nordberg (1936) on the nidicolous arthropods of bird’s nests in Finland (mainly from Aland, a few nests also from Tvärminne and Helsingfors), but unfortunately only three pseudoscorpion species had been identified. Krumpal & Cyprich (1988) tried to define ecological preferences of the 19 pseudoscorpion species found during their survey in the Czech Republic in 162 nests (representing 54 bird nest types) in relation to nest type (free nests, nests in nest boxes, nests in synanthropic habitats, nests in hollow trees) and seasonal changes. Ressl (1963) and Simon (1966), but also Jones (1978) discussed the eventual dispersal of pseudoscorpions by birds and the possible colonization of birds’ nests. Recently, Christophoryova & Krumpalova (2010) distinguish within the pseudoscorpions nidixenous species (which occur accidentally in bird nests, the nymphal stages are represented sporadically) and nidiphilous or nidicolous species. They occur regularly in the bird nests, the nymphal stages are represented numerously, and prefer nests in certain habitats with specific building and microclimagtic conditions. An ongoing study on nidicolous arthropods in birds’ nests from Argentina (Turienzo & Di Iorio, 2008; Turienzo et al., 2008, Di Iorio et al., 2010; Turienzo & Di Iorio, unpublished data) has yielded 246643 insects, 5378 soft ticks (Acarina: Argasidae) and 6406 pseudoscorpions. Consequently, a summarization of the knowledge concerning the pseudoscorpions known from this biotope worldwide is needed for further comparison. The main purpose of the present work is to: 1) provide a compilation of the information on pseudoscorpion species and families recorded from birds’ nests, and 2) state which bird species and families are involved worldwide. MATERIAL AND METHODS The taxonomic and biological publications on pseudoscorpions were reviewed, as well as papers treating inhabitants of birds’ nests; also included are unpublished identifications collated by one of us (V. M.). The bird families and species, followed by those of the associated pseudoscorpions, are listed in alphabetical order. All references were verified, except those indicated as “cited by”, Museum collections and indications not given in original sources are cited between square brackets [ ]. Bird species lists of the American Ornithologists’ Union (1998), Remsen et al. (2008) and the Comitê Brasileiro de Registros Ornitológicos (2007) were used for current nomenclature; subspecific taxa not treated in these lists were updated from Peterson (2002). The nomenclature of pseudoscorpions is adopted from Harvey (2009). Old combinations, synonyms, misidentifications, original localities, number of specimens, and depositories when they were stated, are provided in each case. Pertinent comments in the references and controversial data are included in notes below the respective items.

USA: Florida, in poultry manure (Propp & Morgan, 1985). pseudoscoRpions in biRds’ nests 591 DISCUSSION 14 families of pseudoscorpions with 63 genera and 85 species are recorded from birds’ nests. Chernetidae are dominant with 22 genera and 35 species, these numbers represent about 19% of the described genera and 5% of the described species in this family (Harvey, 2009). It is followed by Chthoniidae (5 genera/subgenera and 9 species) (= about 1.3% of the described species), Cheliferidae (5 genera and 6 species/subspecies) (=about 8% of the decribed genera and about 2% of the described species!), Olpiidae (4 genera and 4 species), Withiidae (4 genera and 7 species) (= about 11% of the described genera and 4.5% of the described species!), Atemnidae (4 genera and 5 species/subspecies), Cheiridiidae (2 genera and 5 species), Neobisiidae and Geogarypidae (1 genus and 4 species each), Larcidae (1 genus and 2 species), Garypidae, Ideoroncidae, Pseudogarypinidae (1 species each), Syarinidae (1 species). The predominance of Chernetidae might be explained partly by the corticolous biology of many of its species. 45 families of birds have been recorded, represented by a total of 98 identified species and a certain number of unidentified taxa, a very small part compared to the number of species and families recognized world-wide (about 142 families and 9700 species). The ranking is headed by Procellariidae, Turdidae (7 spp.) each, Furnariidae (6 or 5 spp.), Hirundinidae (5 spp.), Picidae, Sylviidae (4 spp. each), Strigidae (4 spp.), Anatidae, Cacatuidae, Corvidae, Estrildidae, Laniidae, Paridae, Psittacidae, Troglodytidae (3 spp. each), Anatidae, Passeridae (3 spp. each), Apodidae, Ardeidae, Cisticolidae, Columbidae, Laridae, Motacillidae, Muscicapidae, Phasianidae, Pycnonotidae (2 spp. each), Accipitridae, Cinclidae, Climacteridae, Coraciidae, Emberizidae, Formicariidae, Fringillidae, Halcyonidae, Icteridae, Meropidae, Nectariidae, Panuridae, Phalacrocoracidae, Remizidae, Sittidae, Sturniidae, Tetraonidae, Tyrannidae, Tytonidae, and Upupidae (1 sp. each). Easy accessibility of nests for human observers explains probably the predominance of certain families. Little information can be gathered from listing pseudoscorpions and birds’nests per country. That reflects only the interest of collectors in the mentioned countries, or particular interest in other arthropod groups present in birds’ nests. This fact is emphasized by the leading position of Austria (17 bird species studied, but compare this to the over 200 bird species breeding in Austria!) which is almost exclusevily due to the activity of one single person, Franz Ressl from the Scheibbs District, Lower Austria. The prominence of Slovakia is due to a research program initiated mainly by J. Kristofik, and the many data from Malaysia are the results of the collecting by H. E. McClure and Lim Boo-Liat (Beier, 1963, 1964). From some European countries we do not have any record (e.g. Spain, Belgium, Greece, etc.). Several countries in tropical areas (i.e. Brazil, Venezuela, India, Uganda) have very few records of pseudoscorpions from birds’ nests. A similar situation was presented for the insect fauna in birds’ nests from the Neotropical Region (Di Iorio & Turienzo, 2009). Furthermore, it can be pointed out that indications of origin in older collections were sometimes incomplete, without any information on habitats (see Parazaona bucheri and Parachernes argentinus under Phacellodomus sp.). The presence of pseudoscorpions in birds’ nests is certainly favoured by good or optimal living conditions offered by this particular niche: abundance of potential 592 p. tuRienZo et al. prey (mites, larvae of various insects, e.g. fleas and dipteras, in the nests, biting lice (Mallophaga) directly on the birds), and also microclimatic conditions without large variation in humidity, temperature and light (nests in hollow trees) (see Krumpal & Cyprich, 1988 and Christophoryova & Krumpalova, 2010). It is evident that the building site of nests highly influences the presence of one or another pseudoscorpion family. Nests built on the ground will be visited mainly by soil-dwelling genera and species, e.g. Chthoniidae (genera Chthonius, Tyrannochthonius), Neobisiidae (Neobisium), Olpiidae, Geogarypidae and, to a lesser extent, Garypidae and Syarinidae or even Withiidae (animals of this family are found in litter or under stones, but also under the bark of living or fallen trees). Mundochthonius styriacus (Chthoniidae) and Anthrenochernes stellae (Chernetidae) seem to prefer the constant conditions of hollow trees and are therefore frequently found in birds’ nests constructed in this habitat. On the other hand, many species of usually bark-inhabiting families (Cheiridiidae, Chernetidae, Cheliferidae) are regularly colonizing nests in trees, but the presence of several genera, e.g. Dactylochelifer (Cheliferidae), Apatochernes, Chelanops, Chernes or Sundochernes (Chernetidae) is common, though probably not very frequent. Biology is explaining the sporadic presence of the tritonymph of Neobisium sylvaticum in nests in trees: this stage frequently climbs on shrubs and trees (Beier, 1963b) and arrives accidentally in nests. Some species of Cheiridiidae (Apocheiridium spp., Cheiridium museorum), Cheliferidae (Chelifer cancroides) and Chernetidae (Dinocheirus panzeri) are regularly colonizing nests of synanthropic birds (e.g. Columba livia, Passer domesticus, Gallus gallus) or may be passively dispersed by other birds (e.g. Larca lata by Phoenicurus ochrurus: Ressl, 1963b, 1965). The abundance of pseudoscorpions is usually low (particularly in most ground nests), but may be very high in old nests in the nature, and even more so in nests of synanthropic bird species. Only a few species can be considered as (more or less) exclusive colonizers of tree nests of birds, as far as we can judge from the scarce surveys and collecting data. These are Diplotemnus insularis Chamberlin (St Paul’s Islands), Hesperochernes montanus (USA) (Beier, 1948), Troglochernes dewae (Australia) (Harvey & Volschenk, 2007), Parazaona bucheri, Parazaona morenensis (Turienzo, Di Iorio & Mahnert, unpublished data) and Calidiochernes musculi (South America) (Beier, 1957). On the other hand, some common bark-inhabiting species of the genera Victorwithius and Dolichowithius (Withiidae from South America) have never or very rarely been found in birds’ nests. Even more surprising is the quasi total absence in nests of some Atemnidae, e.g. Paratemnoides nidificator (Balzan), P. pallidus (Balzan), and P. elongatus (Banks). These species show evidence of social behaviour and can be found in huge numbers under the bark of standing or fallen trees. ACKNOWLEDGEMENTS The authors express their deep thanks to Dr Mark S.
