Elongate-oblong, small to moderate-sized, ranging from about 8–14 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, 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, moderately separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn. Antennae distinctly shorter (females) or slightly longer (males) than overall body length; scape clavate, about as long as antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, conical, wider at base, without lateral tubercles. Elytra with sides attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate. Procoxae without projection. 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: moderately large eyes; conical pronotum, wider at base, without lateral tubercles; and elytra with sides attenuate.
Strongly resembles Furona and superficially resembles Alexera, Neolampedusa, Tulcoides, and Venustus.
