Genus: Furona

Diagnostic Features
  • Description: Elongate-oblong, small to moderate-sized, ranging from about 9–13 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons elongate, narrow, about as wide as width of 1–2 lower eye lobes. Eyes with lower lobes oblong. Genae elongate, about as tall to distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles armed at apex with a small projection, or with a short, blunt horn; antennae about as long as overall body length, or as much as 1 2/3 times 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, wider at base, with or without lateral tubercles. Elytra with sides roughly parallel to slightly attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate punctation, surface coarsely punctate. Procoxae without projection (females) or with small acute projection or distinct, curved hook (males). Mesosternal process with apex deeply emarginate. Metafemora long to moderate in length, about 1/2–1/3 as long as elytra.

  • The combination of the following characters will help to distinguish this genus: moderately-large eyes; elytra with sides roughly parallel to slightly attenuate; elytral apices individually rounded; and moderate to long metafemora.

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