Elongate-oblong, robust, small to moderate-sized, ranging from about 10–14 mm in length. Integument generally dark brown or ferrugineous with whitish, black, ferrugineous, and ochraceous pubescence. Head with frons roughly subquadrate to transverse, about as wide as width of three lower eye lobes. Eyes with lower lobes small, ovate. Genae elongate, distinctly taller than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex (females) or armed with small projection (males). Antennae distinctly shorter than overall body length, about 1/2 as long; scape clavate, longer than antennomere IV; antennomere III nearly straight or curved, longer than antennomere IV. Pronotum subquadrate to slightly elongate, cylindrical, without lateral tubercles. Elytra with sides roughly parallel to distinctly expanding to apex; elytral apices individually rounded; apical 1/3 of elytra with distinct, whitish macula; base of elytra with four small, blunt tubercles at humeri. Basal 1/3 of elytra with sparse punctation, surface granulate-punctate to coarsely punctate. Procoxae simple, without projection. Mesosternal process with apex subtruncate to feebly emarginate. Metafemora short in length, about 1/4 as long as elytra.
The combination of the following characters will help to distinguish this genus: small eyes, widely separated; pronotum subquadrate to slightly elongate, cylindrical, without lateral tubercles; base of elytra with four small, blunt tubercles at humeri; and apical 1/3 of elytra with distinct, whitish macula.
Strongly resembles Lachaerus.
