Genus: Esonius

• Description: Elongate-oblong, moderate-sized, ranging from about 13–18 mm in length. Integument generally ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate, about as wide as width of 2 1/2 lower eye lobes. Eyes with lower lobes oblong, slightly narrowed. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles not armed at apex (females) or armed with a small projection, or with a short, blunt horn (males); antennae about as long as overall body length (females), or as much as 1 1/2 times as long (males); scape clavate, about as long or longer than antennomere IV; antennomere III sinuate, longer than scape and antennomere IV; antennae annulate. Pronotum transverse, roughly cylindrical to conical, wider at base, with lateral tubercles. Elytra with sides roughly parallel to attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface granulate-punctate. Procoxae without projection (females) or with small acute projection or distinct, curved hook (males). Mesosternal process with apex deeply 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: slightly narrow eyes; sinuate antennomere III; base of elytra with two prominent tubercles at humeri; base of elytra with dense punctation, surface granulate-punctate; distinctly speckled elytra.
