Elongate-ovate, robust, small to moderate-sized, ranging from about 10–18 mm in length. Integument generally dark brown or black with whitish, brown, and ochraceous pubescence. Head with frons elongate, about as wide as width of 2 1/2 lower eye lobes. Eyes with lower lobes ovate-oblong. Genae elongate, about as tall as lower eye lobes. Antennal tubercles prominent, narrowly separated, contiguous at base; tubercles armed at apex with a small projection, or with a short, blunt horn. Antennae about as long as overall body length, or as much as twice as long; scape gradually expanded to apex, longer than antennomere IV; antennomere III nearly straight, about as long as scape and longer than antennomere IV. Pronotum transverse, roughly conical, wider at base, with lateral tubercles. Elytra with sides attenuate; elytral apices individually 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 granulate-punctate. Procoxae without projection (females) or with small acute projection (males). Mesosternal process with apex deeply emarginate. Metafemora moderate in length, about 1/3 as long as elytra.
The combination of the following characters will help to distinguish this genus: narrowly separated antennal tubercles, contiguous at base; scape gradually expanded to apex; roughly conical pronotum, with distinct lateral tubercles; and base of elytra with two prominent tubercles at humeri.
