subdivision or article of the tarsus, usually numbering from two to five

Form elongateelongate:

the upper and dorsal part of the prothorax
a little wider than long, convex, rounded at sides, narrowed more toward basebase:
the part of any appendage or structure that is nearest the body
than apexapex:
end of any structure distad to the base
, without large tomentose depression on each side; presternum with intercoxal process slightly arched, sloping gradually posteriorly, usually a little widened toward end. 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
with rounded apicesapex:
end of any structure distad to the base
. Legs moderate; femora gradually thickened, not clavateclavate:
thickening gradually toward the tip
, posterior pair not reaching elytral apices; posterior tarsitarsus:
the leg segment distal to the apex of the tibia, bearing the pretarsus; consists of one to five tarsomeres (including pretarsus)
with first segment not longer than 2 following together (Linsley 1962Linsley 1962:

Trichoferus, Stromatium

Differential diagnosis

Differs from Trichoferus by the lack of erect elytral setaeseta:
a sclerotized hair-like projection of the cuticle
in a lateral view. Stromatium differs by having spined elytral apicesapex:
end of any structure distad to the base
and a dentate projection on the antennal tubercletubercle:
a small knoblike or rounded protuberance
near the vertexvertex:
the top of the head between the eyes, frons and occiput, anterior to the occipital suture
.
