Genus: Cnemosioma

• Description: Elongate-ovate, moderate-sized, ranging from about 14–18 mm in length. Integument generally dark brown with whitish and ochraceous pubescence. Head with frons elongate, about as wide as width of 1 1/2 lower eye lobes. Eyes with lower lobes ovate. Genae elongate, about as tall to distinctly taller than lower eye lobes. Antennal tubercles prominent, moderately to narrowly separated; tubercles not armed at apex; antennae about as long or 1 1/3 times as long as overall body length; scape clavate, about as long or longer than antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly conical, distinctly wider at base, without lateral tubercles. Elytra with sides strongly attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled; base of elytra with two large, prominent tubercles at humeri; each tubercle rounded, about the size of one lower lobe of eye. Basal 1/3 of elytra with dense punctation, surface granulate-punctate. Procoxae simple, without projection (females). Mesosternal process with apex deeply emarginate. Metafemora moderate in length, about 1/3 as long as elytra.


• The combination of the following characters will help to distinguish this genus: conical pronotum without lateral tubercles; base of elytra with two large, prominent tubercles at humeri; and elytra with sides strongly attenuate.
