Genus: Sulpitus

Diagnostic Features
  • Description: Elongate-oblong, moderate-sized, ranging from about 15–19 mm in length. Integument generally dark brown or black with whitish, ferrugineous, and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes ovate-oblong. Genae elongate, about as tall or distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately to narrowly separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn; antennae distinctly longer than overall body length, as much as twice as long; scape clavate, about as long or shorter than antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to conical, slightly wider at base, 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 coarsely punctate or granulate-punctate. Procoxae without projection or with distinct, curved hook. Mesosternal process with apex feebly to 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: moderately elongate form; antennae distinctly longer than overall body length, as much as twice as long; sinuate antennomere III; and elytra with sides attenuate.
