Genus: Neolampedusa

Diagnostic Features
  • Description: Elongate-oblong, small-sized, ranging from about 9–11 mm in length. Integument generally dark brown with whitish, ferrugineous, and ochraceous pubescence. Head with frons elongate, about as wide as width of nearly two lower eye lobes. Eyes with lower lobes large, oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles armed at apex with a small projection; antennae about as long as overall body length, or as much as 1 1/3 times as long; scape clavate, about as long as 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 generally uniform in coloration or speckled, or with distinct transverse lines; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection or with small acute projection or an obtuse tubercle. 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: eyes large, widely separated; roughly cylindrical pronotum, without lateral tubercles; and elytra with sides roughly parallel.

  • Similar genus/genera: strongly resembles Alexera and Venustus; superficially resembles Furona, Plerodia, and Tulcoides.
