Species in this genus recently documented in the U.S. range in length from 1.8 to 5.7 mm and from 2.1 to 3.1 times as long as wide; the native species is 2.7 mm long and 2.7 times as long as wide. Males are dwarfed and flightless. The color ranges from light reddish brown to almost black. The pronotum is usually longer than wide, but ranges to equal or wider than long. Anterior half of the pronotum has confused asperities and a series of teeth are present on the anterior margin, the central pair being the largest. The scutellum is small and flush with the elytra. The declivity is usually convex and has granules or pointed tubercles. The scape is usually longer than the 5-segmented funicle. The club is obliquely truncate, with two recurved sutures on the anterior face. They have a depressed pregular region. The anterior coxae are contiguous. The vestiture consists of erect, hair-like setae, more abundant posteriorly and on declivity.
