Elongate-oblong, small-sized, ranging from 7–9 mm in length. Integument generally dark brown or black with greenish and ochraceous pubescence. Head with frons elongate, about as wide as width of 1 1/2 lower eye lobes. Eyes with lower lobes oblong. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, narrowly separated, contiguous at base; tubercles not armed at apex or armed with a small projection. Antennae distinctly longer than overall body length, as much as 3 times longer; scape gradually expanded to apex, shorter than antennomere IV; antennomere III nearly straight, longer than scape and antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly cylindrical, without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra without tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection. Mesosternal process with apex subtruncate. 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: distinctly small form; narrowly separated antennal tubercles, contiguous at base; gradually expanded scape; antennae distinctly longer than overall body length, as much as 3 times longer; roughly cylindrical pronotum, without lateral tubercles; and elytra with sides roughly parallel.
Strongly resembles Cylicasta.
