Genus: Leus

• Description: Elongate-oblong, moderate-sized, ranging from about 12–14 mm in length. Integument generally dark brown with whitish, ferrugineous, and ochraceous pubescence. Head with frons elongate, about as wide as width of 2 1/2 lower eye lobes. Eyes with lower lobes ovate-oblong. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles armed at apex with a small projection, or with a short, blunt horn; antennae about as long as overall body length, or as much as 1 1/2 times as long; scape clavate, shorter than antennomere IV; antennomere III curved or sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly conical, wider at base, with or without lateral tubercles. Elytra with sides attenuate; elytral apices individually rounded; elytra with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface coarsely punctate. Procoxae without projection. Mesocoxae with distinct tubercle. Mesosternal process with apex subtruncate to feebly emarginate. 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: moderately large eyes; sinuate antennomere III; roughly conical pronotum; and elytra with sides attenuate.
