Ommata (Ommata) albitarsis Galileo and Martins   , new species

( Figure 6 View Figure 6-7 )

Description. Head reddish; antennal tubercles black. Frons moderately punctate (32 x), covered by a shining, golden-yellow pubescence. Anterior region of the vertex, between the antennal tubercles, with same kind of pubescence. Occiput punctate. Malar area shorter than the lower ocular lobe (female).

Gula black on anterior portion and reddish on posterior region, with punctures more concentrated on the sides. Antennae reach elytral apices, almost at the apex of antennomere VIII. Scape black and punctate. Antennomeres III-VIII black and gradually thicker towards the apical segments; antennomeres IX-X white; antennomere XI with white basal half and a black apical one.

Prothorax ( Figure 6 View Figure 6-7 ) reddish. Gradually wider sides towards the base; the widest point is next to the basal constriction. Pronotum and sides of the prothorax punctate. Prosternum with a black band next to each procoxa; the posterior half is covered by a whitish pubescence. Mesosternum and metasternum black covered by a whitish pubescence, except metepisternum, with a slight metallic green shining. Sides of the metasternum, mesepisternum and metepisternum punctate. Scutellum black with a whitish pubescence.

Elytra metallic-green, indistinctly blue at the basal region; small reddish portions at sides of scutellum; elytral margins slightly narrower towards the apex; densely punctate throughout the entire surface. Elytral apices rounded and reaching the base of urosternite V.

Protrochanters reddish. Profemora black. Mesotrochanters reddish, mesofemora black with a narrow, reddish basal area. Metatrochanters reddish Metafemora with white pedunculus and a black clava. Tibiae, pro- and mesotarsi black. Metatarsomeres I-IV white; metatarsomere V white at the base and reddish at the apex. Urosternites black covered by a whitish pubescence.

Measurements in mm. Total length, 8.5; prothorax length, 2.1; largest prothoracic width, 1.6; anterior prothoracic width, 1.1; elytra length, 6.0; humeral width, 1.9.

Type material. Female holotype, BRAZIL, Rondônia: Porto Velho (Parque Ecológico), 3.VIII.2008, without name of collector Malaise trap, “terra firme” ( MZSP).

Etymology. Latin, albi = white; Greek, tarsos = tarsi; allusion to white metatarsi.

Diagnosis. Concerning antennomeres IX-X white, prothorax reddish, elytra metallic-green and metatarsomeres I-IV white, Ommata (O.) albitarsis   sp. nov. may be compared with Ommata (O.) paradisiaca Tippmann, 1953   . It differs by antennomere XI white with apical half black; prosternum, with a black band next to each procoxa; mesofemora black with a narrow basal area reddish and elytra unicolor (excepting the reddish basal line beside the scutellum).

Zajciw (1960:94) described the female of O. (O.) paradisiaca   , previously recognized only through the male, with the differential characters: antennomeres IV to VI black and antennae surpassing the elytral apices by their last two articles (the remaining are secondary sexual characters). In O. (O.) paradisiaca   , antennomere XI is entirely white, the prosternum is entirely black, the basal halves of mesofemora are white and the elytra present a yellowish longitudinal band, which gradually narrows from the base to the middle.
