Uruleskia parcapilosa sp. nov.

( Figures 19-21 )

Diagnosis: fronto-orbital plate white with golden pruinosity near the vertex; parafacial white; 6-10 pairs of frontal setae, 1-2 pairs below the level of antennal insertion; short ocellar setae similar in length with the shorter frontals; inner vertical setae crossed, outer verticals present; palpus similar in length with flagellomere; proboscis about 1.0 time the head height; scutum brown in ground colour with golden pruinosity; wing vein R 1 with 1-5 basal setulae on dorsal surface and vein R 4+5 setulose from base to crossvein r-m on dorsal surface; scutellum yellowish; with one pair of basal setae; one pair of subapical setae and one pair of short discal setae; abdomen yellowish usually with small median apical brown spot laterally on T 3 to T 5 and rarely small median apical brown spot dorsally on T 3 and T4.

Description: Male. Body length: 6.0-8.0 mm; wing: 5.5-7.5 mm.

Head: general colour white; fronto-orbital plate white with golden pruinosity near the vertex; eyes reaching the vibrissal level; 6-10 pairs of frontal setae, 1-2 pairs below the level of antennal insertion; short ocellars similar in length with the shorter frontals; frons with 0.15 of head width at the level of the anterior ocellus; inner verticals crossed, outer verticals present; flagellomere slightly brown, yellow on base; proboscis about 1.0 time the head height; long vibrissa ( Fig. 19 ); 5-8 pairs of subvibrissal setulae, shorter near vibrissa; palpus yellow.

Thorax: scutum brown in ground colour with golden pruinosity; acrostichals 1+1; dorsocentrals 2+3; intraalars 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 hyaline, vein R 1 with 1-5 basal setulae 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 1 short anterodorsal seta; 1 dorsal subapical seta; 1 posteroventral apical seta; mid femur with 2-3 sparse posteroventral setae on basal half; 1 posterodorsal subapical seta; mid tibia 1 strong anterodorsal seta 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 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 midle 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 3 and T 4 rarely with small median apical brown spot dorsally; T 3 to T 5 usually with brown spots laterally.

Male terminalia: sternite 5 as described for the genus; surstyli little longer than with cerci, with short ventral spines upwards directed on apical fourth ( Fig. 20 ); cerci narrow and abrupt curved inward at middle, tip curved backwards in lateral view ( Fig. 21 ); pregonite triangular in lateral view and postgonite narrow in lateral view.

Female: Differs from male as follows: frons with 0.25 of the head width at anterior ocellus level; frontoorbital plate with golden pruinosity; outer verticals more developed; 2 pairs of proclinate orbital setae and 2 pairs of reclinate orbital setae; palpus little swollen at tip; mid femur with 1 anterior setae on middle third.

Geographic record: Brazil (Amazonas).

Derivation of the specific epiteth: due to the presence of few setulae on basal fourth of vein R 1.

Comments: easily recognized by the presence of setulae on basal fourth of vein R 1, and few apical spines on ventral surface of surstyli.
