- Description: Elongate-oblong, small to moderate-sized, ranging from about 8–17 mm in length. Integument generally dark brown with whitish, ferrugineous, and ochraceous pubescence. Head with frons distinctly transverse, about as wide as width of five lower eye lobes. Eyes with lower lobes ovate. Genae elongate, distinctly taller 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 distinctly shorter than overall body length, from about 2/3–3/4 as long; scape clavate, longer than antennomere IV; antennomere III shape sexually dimorphic, from clavate (females) or strongly elliptical (males), about as long or longer than scape and about as long or longer than antennomere IV. Pronotum transverse, roughly cylindrical, with lateral tubercles; pronotal disk with large glabrous area at center. Elytra with sides roughly parallel to slightly expanding to apices; elytral apices individually rounded; basal 2/3 of elytra whitish with apical third darker; base of elytra without prominent tubercles at humeri. Basal 1/3 of elytra with sparse to moderate punctation, surface finely punctate. Procoxae without projection. Mesosternal process with apex subtruncate or 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: small eyes, widely separated; frons distinctly transverse; clavate or strongly elliptical antennomere III; center of pronotal disk with large glabrous area; and elytra with sides roughly parallel to slightly expanding to apices.
- Similar genus/genera: strongly resembles Clavidesmus, Cydros, and Strioderes.
- The type species of this genus was originally described in the genus Eudesmus.
