Type species

Chramesus hicoriae LeConte

Adapted from Wood 1982, p. 315-347


Chramesus is distinctive in having a large and asymmetrical bean or kidney-shaped club with no sutures.


The length of the species in this genus ranges from 1.2 to 2.7 mm and are approximately 1.4 to 2.3 times as long as wide. They vary in color from yellowish brown to black, with two species appearing bicolored by virtue of their setae. The pronotum is wider than long. The scutellum is small, visible in all but one species. The crenulations on the anterior margin of the elytra are usually well developed. The declivity is convex, unarmed rarely bearing granules. The vestiture is variable; it consists of scales and/or hair-like setae. The anterior margin of the compound eye is entire. The scape is longer than the 5-segmented funicle. The large, kidney-shaped club is flat and asymmetrical, with no indication of sutures. The procoxae are separated.
