Cherentes

Diagnostic Features

Description

Elongate-oblong, robust, small to moderate-sized, ranging from about 9–12 mm in length. Integument generally ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to transverse, wider than width of five lower eye lobes; entire surface of head finely punctate, each puncture bearing a fine scale in its center. Eyes with lower lobes small and narrow. Genae elongate, distinctly taller than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles unarmed or armed at apex with small projection (males). Antennae about as long as overall body length or distinctly longer, about 1 1/3 times as long; scape gradually expanded to apex or clavate; antennomere III slightly curved or slightly elliptical (some males), longer than scape and about as long or longer than antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum subquadrate, roughly cylindrical to slightly conical, slightly narrower at base, with or without small, lateral, blunt tubercles. Prothorax with sides obliquely and broadly chalky-white. Elytra with sides distinctly expanding to apical 1/3; elytral apices individually rounded; elytra with distinct vittae; lateral margins of elytra with chalky-white maculae; base of elytra without prominent tubercles. Basal 1/3 of elytra sparse punctation, surface finely punctate. Procoxae without projection. Mesosternal process with apex nearly rectangular. Metafemora short to distinctly short in length, about 1/4–1/5 as long as elytra.

Diagnosis

The combination of the following characters will help to distinguish this genus: distinctly small eyes, widely separated; subquadrate pronotum; sides of prothorax and elytra obliquely and broadly chalky-white; elytra with sides distinctly expanding to apices; and short metafemora.
