Rosalba gounellei sp. nov.

( Fig. 11 )

Description. Head with integument reddish-brown. Sides of frons diverging towards the clypeus and covered by whitish-yellow pubescence. Antennal tubercles projected. Upper ocular lobes separated by a distance equal of one row of ommatidia. Vertex with shiny carina in the middle. Antennae reach the apex of the elytra approximately at apex of antennomere VII. Antennomere III shorter than IV.

Integument of prothorax reddish-brown. Sides of the prothorax with small tubercle. The pubescence of pronotum is rubbed, but the punctation is evident and consists of deep and dense punctures.

Elytral integument reddish-brown, darker at base; central basal ridge little projected, general pubescence yellowish-white. On each elytron, bands of yellowish pubescence: (1) longitudinal, close to the suture, from the basal ridge up to the middle; (2) parallel to (1) also from the base to the middle; (3) rounded spot, close to the suture, situated just after the middle; (4) longitudinal, on apical fourth, close to the suture; (5) band parallel to (4), but shorter; (6) on apical fourth, parallel to (5), wider on the anterior portion; (7) close to the margin, from the base up to almost the apex. Elytral apices obliquely truncate.

Legs with integument reddish. Metatarsomere V scarcely longer than I-III.

Measurements, in mm. Total length, 9.7; prothorax length, 1.8; prothorax width 1.9; elytron length, 6.9; humeral width, 2.8.

Etymology. Species name is an homage to french entomologist Émile Gounelle, specialist in the Cerambycidae who collected in Brazil at the end of the 19th century and beginning of the 20th century.

Type material. Holotype male, BRASIL, Amazonas: Fonteboa, Coll. Kraatz ( MZSP). The holotype was probably sent to Luederwaldt by Gounelle that identified it as “ Aletretia variation de inscripta Bates ”.

Discussion. Rosalba gounellei differs from R. inscripta : by the presence of a small tubercle on the sides of prothorax and central-basal ridge of the elytra. In R. inscripta , the sides of the prothorax are unarmed and there is no trace of a central-basal ridge on the elytra. Additionally, the yellowish spot on the middle of elytra is rounded in R. gounellei and triangular and close the suture in R. inscripta .
