Differential diagnosis

Beraba hovorei sp. nov. is similar to B. grammica and B. erosa in having only one eburneous callosity at the anterior region of each elytron and the posterior callosities narrow and elongated, the external one at least one-third of the elytral length and separated for the inner by distance equivalent to the width of a callosity. Beraba hovorei sp. nov. differs of both species by the color pattern: posterior region of head, most of prothorax, mesosternum, metasternum and urosternites dark; antennae, femora and tibiae bicolor; base of elytra and anterior and posterior region of posterior eburneous callosities black and and elytral costae visible between anterior and posterior callosities. In B. grammica and B. erosa the head, prothorax, mesosternum, metasternum and urosternites are brownish-orange, the antennae, femora and tibiae are unicolor (antennae, femora and tibiae brownish-orange in B. erosa and antennae and tibiae black and femora brownish-orange in B. grammica ); elytra with black areas just surrounding the eburneous callosities, and without elytral costae visible between anterior and posterior callosities. Beraba hovorei sp. nov. differs from B. grammica in having the pronotal tubercles black (in B. grammica are of the same color than surface or pronotum) and by the external-posterior eburneous elytral callosities starting ahead the inner-posterior (in B. grammica the external posterior starts behind the inner posterior).

Etymology

The species epithet is in honor of Frank T. Hovore, one of the collectors of the type series, for his contributions to the knowledge of the cerambycid fauna.

Description

Male

Integument brownish-orange. Ventrally dark. Posterior region of head, sides of pronotum, pronotal tubercles, base of elytra, anterior and posterior region of posterior eburneous callosities and elytral spines black. Antennomeres III–X, femora and tibia bicolored: antennomeres with basal half brownishorange and apical half light brown; femora light brown with base brownish-orange and tibiae brownishorange with apex light brown.

Body covered by long, erect and sparse setae, denser at inner face of basal antennomeres. Ventrally with dense grayish pubescence. Distance between upper lobes three times width of upper lobe. Antennae exceeding elytral apices at apex of antennomere VIII. Prothorax as long as width (including lateral tubercle), with lateral tubercle clearly visible, and acute. Pronotum with dense grayish pubescence, glabrous at center and with two anterior tubercles weakly elevated and rounded at top. Surface of pronotum with some shallow wrinkles.

Scutellum covered by dense grayish pubescence. Elytra about 3.5 times longer than prothorax; surface with coarse punctuation on basal half, finer and shallower towards to apex. Each elytron with three eburneous callosities: one basal, elliptical; and two posterior, narrow and elongate (the inner slightly wider than external), the external one at least one-third of elytral length, separated from inner by distance equivalent to width of a callosity, the external starting ahead the inner. Elytral costae visible between anterior and posterior callosities. Apex of elytra with external spine and with acute sutural projection.

Measurements (in mm)

Holotype, total length: 9.3, prothorax length: 1.8, prothorax width at its widest point: 1.7, elytral length: 6.5, humeral width: 2.0. Paratypes, ♂ / ♀, n = 13 / 11. Total length: 8.30±0.56 / 8.60±0.97, prothorax length: 1.72±0.17 / 1.72±0.18, prothorax width at its widest point: 1.51±0.11 / 1.55±0.22, elytral length: 5.83±0.39 / 6.08±0.69, humeral width: 1.80±0.15 / 1.85±0.24.

Variability

The black areas of elytra can be lighter; the dark area at the anterior and posterior region of the posterior eburneous callosities can expand between the callosities and surrounding the external margin of the external callosity. In females, the antennae exceeding elytral apices at antennomere X.
