absent, eye entire/shallowly emarginateemarginate:
notched at the margin
, eye ommatidial density coarse.
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

Prosternum: prosternal process not dilated at apexapex:
end of any structure distad to the base
, procoxal cavities open posteriorly, rarely closed posteriorly.
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
rounded or truncatetruncate:
cut off squarely at the tip

Legs: visible tarsomerestarsomere:
subdivision or article of the tarsus, usually numbering from two to five
: 5, femora robust, protibial spurs: 2, tarsal clawstarsal claw:
usually paired claws of the pretarsus, at the distal end of the leg
simple.

Form robust; integument reddish-brown to brown. 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
with second segment nearly as long as third, following segments transversetransverse:
broader than long
. Pronotumpronotum:
the upper and dorsal part of the prothorax
globular, widest at about middle; posterior coxae prominent. Legs moderately robust; anterior tibiaetibia:
the leg segment distal to the femur, proximal to the tarsus
with a large, conspicuous lamella; posterior tarsitarsus:
the leg segment distal to the apex of the tibia, bearing the pretarsus; consists of one to five tarsomeres (including pretarsus)
not hairy beneath, third segment feebly bilobed, shallowly emarginateemarginate:
notched at the margin
