Genus: Neocherentes

Diagnostic Features
  • Description: Elongate-ovate, small to moderate-sized, ranging from about 9–15 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, black, and ochraceous pubescence. Head with frons subquadrate to transverse, about as wide as width of five lower eye lobes. Eyes with lower lobes distinctly narrow. Genae elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn; antennae about as long as overall body length, or as much as 1 1/2 times as long; scape clavate, shorter than antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical, without lateral tubercles. Elytra with sides roughly parallel; elytral apices individually rounded; elytra with distinct maculae of contrasting color; base of elytra without prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection or with small acute projection. Mesosternal process with apex subtruncate to feebly 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 narrow eyes, widely separated; elytra with distinct maculae of contrasting color; and elytra with sides roughly parallel.

  • Similar genus/genera: this distinctive genus is not easily confused with other genera, but superficially resembles Midamiella and Pseudobeta.
