Rosalba vanini   sp. nov.

( Fig. 9 View FIGURES 7 – 11. 7 )

Description. Integument reddish-brown. Frons and vertex covered with whitish pubescence. Sides of frons divergent downward; between antenniferous tubercles very deep. Distance between upper ocular lobes a little wider than a row of ommatidia.

Antennae reach elytral apices at the tip of antennomere VII. Scape covered by whitish pubescence. Antennomeres III-VII reddish with dark apices (antennae broken at apex of antennomere VII). Antennomere III with fringe of hairs moderately dense on inner side.

Prothorax with short lateral gibbosity. Pronotum with three bands of dense whitish pubescence: one on the middle and one on each side; punctation moderately dense and deep. Sides of prothorax pubescent near the prosternum and crossed by a reddish brown longitudinal band.

Elytra with yellow-whitish pubescence with brown or reddish-brown spots (1) in the base, brown transverse band, narrow, includes a very fine whitish line; (2) in the middle, oblique band not reaching the suture and extending to the margin; this band contains small irregular spots of whitish pubescence and extends to apex in three short lines; (3) in the middle of apical third, longitudinal band, wider than the others and close to the suture; (4) almost at the apex, dorsal, shorter than 3; (5) fused to the margin, in the apical fourth, longitudinal band from band 2 to the elytral apices. Apex of the elytra obliquely truncate with outer spine.

Legs and ventral face reddish with whitish pubescence.

Measurements, in mm. Total length, 7.2; prothorax length, 1.4; prothorax width 1.5; elytron length, 5.1; humeral width, 2.1.

Etymology. Specific name is in homage to Sergio Antonio Vanin who collected the holotype.

Type material. Holotype male, BRASIL, Rondônia: Guajará Mirim (Rio Cabixi, ± 36 km da foz com Rio Guaporé), 16.IV. 1976, S. A. Vanin col. ( MZSP). Paratype female, Amapá, Serra do Navio, IX. 1957, Bicelli col., ex-coleção J. Lane ( MZSP).

Discussion. In the paratype, the reddish-brown spots and bands on the apical half of the elytra are fused in a transverse area of irregular contour which indicates that the reddish-brown spots of the apical half of the elytra varies.

Like Rosalba digna ( Melzer, 1934)   , ( Fig. 10 View FIGURES 7 – 11. 7 ), R. vanini   ( Fig. 9 View FIGURES 7 – 11. 7 ) also has a wide band of yellow-whitish pubescence on the anterior half of elytra. R. vanini   differs from R. digna   by one or two very fine whitish lines inside the brown transverse band of the base. In R. vanini   , the reddish spots, although variable, have a different pattern.

R. vanini   can also be compared with R. inscripta ( Bates, 1866)   which occurs in Amazonia. In R. vanini   , there are no band of yellowish pubescence on the basal and apical half of the elytra, while in R. inscripta   , these bands are present.
