Genus: Cicatrodea

Diagnostic Features
  • Description: Elongate-ovate, moderate-sized, ranging from about 14–15 mm in length. Integument generally dark brown with whitish, brownish, and ochraceous pubescence. Head with frons subquadrate, about as wide as width of two lower eye lobe; frons distinctly convex. Eyes with lower lobes oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or with small projection or short, blunt horn (males); antennae distinctly longer than overall body length, as much as two times longer (males); scape clavate, with distinct cicatrix at apex; about as long or longer than antennomere IV; antennomere III slightly curved, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to conical, wider at base; pronotum without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra with distinct, pale transverse lines; base of elytra without prominent tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface finely punctate to granulate-punctate. Procoxae without projection or with distinct, curved hook (males). 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: distinctly large eyes; scape with distinct cicatrix at apex; pronotum distinctly narrower than elytral humeri; base of elytra with two prominent tubercles at humeri; and elytra with distinct, pale transverse lines.

  • Similar genus/genera: this genus is distinct among Onciderini and the only genus with a cicatrix at the apex of the scape.
