Diagnostic Features
- Description: Elongate-ovate, small to moderate-sized, ranging from about 11–13 mm in length. Integument generally dark brown or black 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 ovate-oblong. Genae elongate, about as tall or distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles armed at apex with small projection or short, blunt horn; antennae about as long as overall body length or as much as 1 1/2 times as long; scape clavate, about as long as antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to slightly conical, wider at base, without lateral tubercles. Elytra with sides slightly 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 dense punctation, surface coarsely punctate or granulate-punctate. Procoxae without projection or with an obtuse tubercle. 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; sinuate antennomere III; roughly cylindrical to slightly conical pronotum; and elytra with sides stightly attenuate.
- Similar genus/genera: strongly resembles Alexera and Neolampedusa; superficially resembles Furona, Plerodia, and Tulcoides.
