Elongate-ovate, robust, small to moderate-sized, ranging from about 10–14 mm in length. Integument generally dark brown with ferrugineous and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes ovate-oblong. Genae elongate, about as tall as lower eye lobes. Antennal tubercles prominent, narrowly to moderately separated; tubercles not armed at apex (females) or armed with small projection (males). Antennae about as long (females) to distinctly longer (males) than overall body length; scape clavate, shorter than antennomere IV; antennomere III sinuate, longer than scape and IV; antennomere XI shorter than X (females) or slightly longer than X (males). Pronotum transverse, conical, wider at base, without lateral tubercles. Elytra attenuate to apex; elytral apices individually rounded; elytra generally uniform in coloration, often with vague, pale vittae; base of elytra with two prominent tubercles at humeri; each tubercle followed by a short carina. Basal 1/3 of elytra moderately to densely punctate, surface coarsely punctate to granulate-punctate. Procoxae without projection (females) or with distinct, curved hook. Mesosternal process with apex deeply emarginate. Metafemora moderate in length, about 1/2–1/3 as long as elytra.
The combination of the following characters will help to distinguish this genus: moderately-sized eyes; conical pronotum, without lateral tubercles; base of elytra with two prominent tubercles at humeri; and elytra attenuate to apex.
Strongly resembles Hesycha, Hypsioma, and Tibiosioma.
