Elongate-ovate, small to moderate-sized, ranging from about 11–15 mm in length. Integument generally dark brown or black with whitish, ferrugineous, brown, and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes oblong. Genae elongate, about as tall as lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles not armed at apex or armed with a small projection. Antennae about as long as overall body length, or as much as 1 2/3 times as long; scape clavate, about as long as antennomere IV; antennomere III variable in shape, from nearly straight to curved to sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to conical, wider at base, without lateral tubercles. Elytra with sides roughly parallel to attenuate; elytral apices individually to jointly rounded; elytra generally uniform in coloration or speckled; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface coarsely punctate or granulate-punctate. Procoxae without projection or with small acute projection or distinct, curved hook. Mesosternal process with apex feebly to deeply emarginate. Metafemora moderate in length, about 1/3 as long as elytra. Metatibiae distinctly expanded in males.
The combination of the following characters will help to distinguish this genus: roughly conical, strongly transverse pronotum, without lateral tubercles; base of elytra with two prominent tubercles at humeri; elytra with sides attenuate; and metatibiae distinctly expanded in males.
