Elongate-oblong, small to moderate-sized, ranging from about 10–13 mm in length. Integument generally dark brown or black with whitish, brown, ferrugineous, and ochraceous pubescence. Head with frons variable, from transverse to elongate, about as wide as width of three lower eye lobes. Eyes with lower lobes ovate-oblong. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn. Antennae about as long as overall body length, or as much as 1 1/3 times as long; scape clavate, about as long or shorter than antennomere IV; antennomere III nearly straight to curved, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to conical, distinctly narrower at base, with or without lateral tubercles; pronotal disk with distinct glabrous area at center. Elytra with sides roughly parallel to distinctly expanding to apex; elytral apices jointly rounded; elytra generally uniform in coloration or speckled; base of elytra without tubercles or with several round, shiny, glabrous tubercle at humeri. Basal 1/3 of elytra with dense punctation, surface granulate-punctate. Procoxae without projection. Mesosternal process with apex subtruncate to feebly emarginate. Metafemora moderate to short in length, about 1/3–1/4 as long as elytra.
The combination of the following characters will help to distinguish this genus: widely separated eyes; distinct glabrous area at center of pronotal disk; and elytra with sides roughly parallel to distinctly expanding to apex.
