Elongate-ovate, moderate to large-sized, ranging from about 14–28 mm in length. Integument generally black or dark brown with whitish, tan, or brownish pubescence. Head with frons elongate, about as wide as width of one lower eye lobe; frons surface roughly sculptured. Eyes with lower lobes large, oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, narrowly separated, contiguous at base; tubercles not armed at apex or armed with a short, blunt horn. Antennae about as long as overall body length, or as much as twice as long; scape gradually expanded to apex, longer than antennomere IV; antennomere III variable in shape, from nearly straight to curved to sinuate, about as long or longer than scape and longer than antennomere IV. Pronotum transverse, roughly conical, wider at base, with or without lateral tubercles. Elytra with sides slightly attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with vague maculae; base of elytra with two prominent tubercles at humeri, often with several additional prominent, shiny tubercles. Basal 1/3 of elytra without punctation or with dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection. Mesosternal process with apex feebly to deeply emarginate. Metafemora moderate to short in length, about 1/2–1/3 as long as elytra.
The combination of the following characters will help to distinguish this genus: large eyes; roughly sculptured frons; narrowly separated antennal tubercles, contiguous at base; and elytra often with several prominent, shiny tubercles.
Strongly resembles Hypselomus and Typhlocerus.
