Material examined.

Colombia, Bolívar: San Jacinto (Reserva La Flecha, 09°51'12.4"N, 75°10'41.4"W, tropical dry forest), 1 male, 27.IV.2017, I. Mendoza coll., light trap (UARC). Venezuela, Aragua: El Limón, 1 male, 23.V.1997, F. Fernandez coll., mercury light (MZSP).

Redescription.

Male. Integument dorsally orange, brownish orange ventrally. Posterior region of head, pronotum, lateral tubercles of prothorax and legs brownish orange. Elytra and scutellum yellowish orange. Pronotal tubercles, posterior region of anterior eburneous callosities and, region around posterior eburneous callosities black.

Body covered with long, erect, sparse setae, denser on inner surface of tibiae, tarsomeres and basal antennomeres.

Head. Posterior region of head, scape and basal antennomeres with dense punctuation. Distance between upper lobes about three times width of upper lobe. Antennae exceeding elytral apices at apex of antennomere VIII. Prothorax (including lateral tubercles) 1.14 times longer than wide; lateral tubercles distinctly visible, acute at apex.

Thorax. Surface of pronotum with coarse dense punctuation; with two anterior elevated tubercles rounded at apex. Prosternum smooth on central region, with long, erect setae and a few punctures, with evident sexual punctation at lateral sides concentrated on subrounded areas (Figs 16, 18). Coxae and mesoventral process covered with dense whitish pubescence. Meso- and metaventrite with long erect setae and covered with dense whitish pubescence laterally. Femora and tibiae fine and long; apex of meso- and meta-femora with long inner spine.

Elytra about 3.5 times longer than prothorax; surface with dense, coarse punctures basally, finer and shallow toward apex. Each elytron with three eburneous callosities: one basal, elliptical; two posterior, slightly elongated, inner one slightly smaller than external one, not distinctly separated from each other. Posteroexternal callosity about one fifth of elytral length, starting ahead of internal one. Elytral costae absent. Apex of elytra with external long spine, about 0.8 times as long as the pedicel and with acute sutural projection.

Measurements. Male. Total length, 10.3; prothorax length, 2.1; prothorax width at its widest point, 1.9; elytral length, 7.3; humeral width, 2.0.

Discussion.

Beraba limpida was described by Martins (1997) based on a single female specimen, and until now the male remained unknown. Among the known males of Beraba , just one species has sexual punctation, B. piriana Martins, 1997. The sexual punctation in this species covers the entire prosternum and extends to the lateral region of the pronotum. Herein, we report sexual punctation for the first time in other two species of Beraba : B. limpida and B. angeli sp. n. In those species, the sexual punctation covers the entire surface of the pronotum, and is concentrated in subrounded areas on sides of the prosternum (Figs 9, 11, 16, 18).

One specimen of Beraba tate Galileo & Martins, 2010 was illustrated by Galileo et al. (2008) as being B. limpida . Later, Galileo and Martins (2010) recognized that this specimen belongs to a new species, and described it as B. tate . However, Galileo et al. (2008) remains wrongly listed in the references on B. limpida (see Monné 2018; Tavakilian and Chevillotte 2018). In order to correct this error, we point out that this reference should appear on B. tate .
