Remarks

The genus Quiacaua was described by Martins (1997) and characterized by the shiny integument, the scape subpiriform and with basal sulcus; the prothorax with lateral tubercles well developed and antero-lateral tubercles weakly developed; the surface of pronotum rugose-punctate; the mesosternum with tubercle; the elytral apex with a long external spine and a sutural projection and the meso- and metafemora with long inner spine. Currently, the genus is comprised of only two species.

Key to species of Quiacaua (modified from Martins 1999)

1. Posterior-central callus of pronotum strongly elevated (almost attaining height of pronotal tubercles); eburneous callosities of elytra elongate, the center separated between them;

behind anterior eburneous callosities, in front and behind central eburneous callosities and at apex of elytra with dark areas. Brazil (Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro) ……………………………………………… Q. vespertina ( Monné & Martins, 1973) comb. nov.

– Posterior-central callus of pronotum flattened or weakly elevated; eburneous callosities of elytra elliptical, central callosities contiguous, without black areas at the elytra …………………………2

2. Pronotum with posterior-central spot black; mesosternum punctate; external-central eburneous callosities of elytra curved, involving external side of inner-central. Brazil (Minas Gerais, Espírito Santo, Rio de Janeiro) …………………………………………………… Q. abacta (Martins, 1981)

– Pronotum without posterior-central spot black; mesosternum smooth; external-central eburneous callosities of elytra straight, not involving the inner-central. Brazil (Amazonas, Pará, Maranhão) …………………………………………………………… Q. taguaiba Martins, 1997
