AntennaeAntenna:
in larval and adult insects, paired segmented appendages, borne one on each side of the head, functioning as sense organs and bearing a large number of sensilla
: antennal length reaching/surpassing end of body, antennal flagellar segments elongateelongate:
much longer than wide

a scar; a scar-like structure
(scar) at apexapex:
end of any structure distad to the base

the first proximal segment of the antenna
.

the upper and dorsal part of the prothorax
shape transversetransverse:
broader than long
, rarely subquadratesubquadrate:
not quite a square

the upper and dorsal part of the prothorax
lateral armature absent.

ElytraElytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
: elytral length reaching or close to end of abdomen, elytral apicesapex:
end of any structure distad to the base
