Uruleskia extremipilosa sp. nov.

( Figures 11-14 )

Diagnosis: fronto-orbital plate with dense golden pruinosity and parafacial white; 10-15 pairs of long frontal setae in males 6-8 pairs in females, 1-2 pairs below the level of antennal insertion; short ocellar setae similar in length with the shorter frontals; palpus similar in length with flagellomere; proboscis 1.2 times the head height; scutum with dense golden pruinosity; wing vein R 1 setulose on apical half on dorsal surface and vein R 4+5 setulose from base to crossvein r-m on dorsal surface; scutellum yellowish with golden pruinosity; with one pair of basal setae; one pair of subapical setae and one pair of short discal setae; abdomen yellowish with brown spots laterally on T 4 and T 5 and rarely on T 3.

Description: Male. Body length: 6.0-7.0 mm; wing: 5.5-6.5 mm.

Head: ground colour white; fronto-orbital plate with dense golden pruinosity; 10-15 pairs of frontal setae, 1-2 pairs below the level of antennal insertion; short ocellars setae similar in length with the shorter frontals; frons with 0.10 of head width at the level of anterior ocellus; inner verticals present, outer verticals almost indistint from the postoculars; flagellomere slightly brown, yellow on base; proboscis about 1.2 times the head height; long vibrissa; 5-8 pairs of subvibrissal setulae, shorter near vibrissa.

Thorax: scutum with dense golden pruinosity; acrostichals 2+1; dorsocentrals 2+3; intra-alars 1+3; post-pronotals 2; scutellum yellowish with golden pruinosity; one pair of basal setae; one pair of subapical setae and one pair of short discal setae. Wing and calypter slightly infuscated, vein R 1 setulose on apical half on dorsal surface and vein R 4+5 setulose from base to crossvein r-m on dorsal surface. Legs with coxa, trochanter, femur and tibia yellowish and tarsus brown; fore tibia with one anterodorsal row of short setae; 1 dorsal subapical seta; 1 posteroventral apical seta; mid femur with 1 anterior seta on middle third; 2-3 long and sparse posteroventral setae on basal half; 2 posterodorsal subapical setae; mid tibia with 1 strong anterodorsal and 1 strong ventral seta on middle third; 2 posterior setae on middle third; 1 anterodorsal and 1 dorsal subapical seta; 1 anteroventral, 1 ventral and 1 posteroventral apical seta; hind femur with 4-5 anteroventral setae on basal half with and 1 seta on apical third; 4-5 sparse posteroventral setae on basal half; hind tibia with one anterodorsal row of setae, the median one the largest; 2-3 ventral setae on middle third, the apicad the largest; 1 posterodorsal subapical seta and 1 anterodorsal subapical seta; 1 anteroventral apical seta.

Abdomen: yellow; T 1+2 not excavate to its hind margin; T 4 and T 5 and rarely T 3, with brown spots laterally.

Male terminalia: sternite 5 as in ( Fig. 11 ); surstylus longer than cerci with many short ventral spines upwards directed near the apex ( Fig. 12 ); cerci short and well curved inward at middle ( Fig. 13 ); apex slightly curved backwards; pregonite triangular in lateral view; postgonite narrow in lateral view ( Fig. 14 ).

Female: Differs from male as follows: frons with 0.25 of the head width at the level of anterior ocellus; 2 pairs of proclinate orbital setae and 2 pairs of reclinate orbital setae; outer verticals setae distinct; palpus little swolllen at tip.

Geographic record: Brazil (Roraima, Amazonas and Rondônia) .

Derivation of the specific epiteth: due to the presence of setulae on apical half of dorsal surface of vein R 1. Derived from the latin word extremus, which means extremity.

Comments: recognized from the other congeneres by the golden pruinosity on fronto-orbital plate and parafacial and vein R 1 setulose on apical half on dorsal surface.
