Rosalba cacapyra sp. nov.

( Fig. 2 )

Description. Head with black integument. Frons covered with white pubescence. Frontal and coronal sutures deep. Vertex black with whitish pubescence behind the upper ocular lobes. Upper ocular lobes with six rows of ommatidia separated by distance equal to two rows of ommatidia. Lateral regions of the head, behind the eyes, with pubescence yellowish. Antennae reach the elytral apices approximately at the base of antennomere IX. Scape black, robust, with sparse whitish pubescence. Antennomere III black, with fringe of dense hairs on inner side. Antennomeres IV-XI black with orange basal ring.

Prothorax black with small lateral tubercules at middle. Lateral parts of the prothorax covered with yellowishorange pubescence. Pronotum, on each side, with wide band of whitish-yellow pubescence; middle of pronotum with indistinct narrow band of yellowish pubescence.

Elytra with black integument, more reddish on the suture from the anterior fourth to the apex. Humeri covered by yellowish orange pubescence up to the anterior third on a wide longitudinal band. Apical third of each elytron with a small oblique spot of whitish pubescence close to the suture; toward the outer side of this spot, the elytra are covered by yellowish-orange pubescence; apical fourth covered by whitish pubescence, more yellowish at apices. Punctation dense and deeper on dorsum of anterior half. Elytral apices obliquely truncate.

Profemora with black integument on ventral side and yellowish on dorsal one; covered by yellowish-white pubescence. Mesofemora with integument black on inner side and reddish on outer and dorsal sides. Metafemora black with the dorso-apical side of integument reddish covered by yellowish pubescence; with wide ring on peduncle. Tibiae reddish with apical half or third black. Tarsomeres I, II and V black with reddish base.

Thoracic sterna with reddish integument black on sides of metasternum and covered with yellowish pubescence.

Urosternites covered by yellowish pubescence; I and II with lateral spot of black integument; V with two longitudinal bands black.

Measurements, in mm. Total length, 7.1; prothorax length, 1.4; prothorax width, 1.5; elytron length, 5.1; humeral width, 2.0.

Etymology. Tupi: çacapyra = tip; refers to elytral apices covered by whitish pubescence.

Type-material. Holotype female, ECUADOR, Orellana: Loreto (11 km E), 28.VIII.2004, F. T. Hovore col. (CASC).

Discussion. Some other species of Rosalba have elytral apices with spot of whitish or yellowish-white pubescence: R. alboapicallis ( Breuning, 1940) , R. formosa Martins & Galileo, 2008 and R. strandiella ( Breuning, 1940) . R. cacapyra sp. nov. is distinguished from all by the color pattern of the elytra.
