Elongate-oblong, small to large-sized, ranging from about 11–26 mm in length. Integument generally ferrugineous with whitish and ochraceous pubescence. Head with frons subquadrate, about as wide as width of three lower eye lobes. Eyes with lower lobes oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn. Antennae distinctly longer than overall body length, as much as twice as long; scape clavate, variable in length compared to antennomere IV; antennomere III nearly straight to curved, longer than scape and antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly cylindrical to conical, wider at base, without lateral tubercles. Elytra with sides roughly parallel; elytral apices jointly rounded; elytra generally uniform in coloration or speckled; base of elytra without tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface finely punctate to granulate-punctate. Procoxae without projection or with distinct, curved hook. Mesosternal process with apex feebly emarginate. Metafemora moderate in length, about 1/3 as long as elytra.
The combination of the following characters will help to distinguish this genus: widely separated eyes; frons subquadrate; antennae distinctly longer than overall body length, as much as twice as long; base of elytra with two prominent tubercles at humeri.
Superficially resembles Lochmaeocles.
