Genus: Proplerodia

Diagnostic Features
  • Description: Elongate-oblong, moderate-sized, ranging from about 13–14 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to elongate, about as wide as width of three lower eye lobes. Eyes with lower lobes oblong. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex; antennae distinctly longer than overall body length, as much as 1 1/3 times as long; scape clavate, about as long as antennomere IV; antennomere III variable in shape, from nearly straight to curved to sinuate; antennomere III longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to 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 without tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate. Procoxae without projection or with small acute projection or distinct, curved hook. Mesosternal process with apex feebly to 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: widely separated eyes; genae distinctly shorter than lower lobe of eyes; pronotum without lateral tubercles; and elytra with sides attenuate.

  • Similar genus/genera: superficially resembles Glypthaga and Sternycha.
