Genus: Iaquira

Diagnostic Features
  • Description: Elongate-ovate, small-sized, ranging from about 7–9 mm in length. Integument generally dark brown with greenish and ochraceous pubescence. Head with frons elongate, about as wide as width of two lower eye lobes. Eyes with lower lobes ovate. Genae elongate, about as tall as lower eye lobes. Antennal tubercles prominent, moderately separated; tubercles not armed at apex; antennae about as long as overall body length, or about 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 or conical, wider at base, without lateral tubercles. Elytra with sides attenuate; elytral apices individually or jointly rounded; elytra generally uniform in coloration; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection. Mesosternal process with apex feebly emarginate. Metafemora long or moderate in length, about 1/2–1/3 as long as elytra.

  • The combination of the following characters will help to distinguish this genus: relatively small-sized; integument generally dark brown with greenish and ochraceous pubescence; elytra with sides attenuate; and base of elytra with two prominent tubercles at humeri.

  • Similar genus/genera: this distinctly small species strongly resembles Priscatoides and some species of Tulcus, and superficially resembles Hesycha and Lydipta.
