Elongate-oblong, moderate-sized, ranging from about 10–20 mm in length. Integument generally dark brown with whitish, brown, and ferrugineous pubescence. Head with frons subquadrate, about as wide as width of four lower eye lobes. Eyes with lower lobes distinctly narrow. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex (females) or with a small projection (males). Antennae about as long (females) or as much as twice as long (males) as overall body length; scape clavate, shorter than antennomere IV; antennomere III sinuate or curved, longer than scape, about as long or longer than antennomere IV. Pronotum transverse, roughly cylindrical to conical, slightly narrower at base, without lateral tubercles. Elytra with sides roughly parallel to distinctly attenuate; elytral apices individually rounded; basal 2/3 of elytra with transverse raised lines forming a vague X shape, apices with distinctly darker maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface finely punctate to coarsely punctate. Procoxae simple, without projection. Mesosternal process with apex subtruncate to feebly emarginate. Metafemora short in length, about 1/4–1/5 as long as elytra.
The combination of the following characters will help to distinguish this genus: distinctly narrow eyes, widely separated; roughly cylindrical pronotum without lateral tubercles; basal 2/3 of elytra with transverse raised lines forming a vague X shape; and short metafemora.
Strongly resembles Trestonia and superficially resembles Apocoptoma and Leus.
