Genus: Priscatoides

Diagnostic Features
  • Description: Elongate-oblong, moderate-sized, about 13 mm in length. Integument generally dark brown or black with brown and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes oblong. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, narrowly separated; tubercles armed at apex with small projection; antennae distinctly longer than overall body length, 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; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly cylindrical, without lateral tubercles. Elytra with sides 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 or with small projection. 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: sinuate antennomere III; roughly cylindrical pronotum, without lateral tubercles; base of elytra with two prominent tubercles at humeri; and elytra with sides attenuate.
