Genea paulistana sp. nov.

( Figures 22-26 )

Male: Body length, 6.0-7.0 mm; wing, 5.0-6.0 mm.

Head: Parafacial and fronto-orbital plate white with slight golden pruinosity; vitta yellow; 8-10 pairs of frontal setae, 2-3 pairs below the level of the antennal insertion; tiny ocellar setae; frons with 0.10 of the head width at the level of the anterior ocellus; inner verticals crossed outer verticals distinct; antenna yellow; flagellomere brown, yellow on base; arista slightly plumose; proboscis long with 1.3 times the head height ( Fig. 22 ); long vibrissa; 3-5 pairs of subvibrissal setulae, shorter near vibrissa; 1-2 pairs of setulae above vibrissa; palpus long, yellow and filiform with almost twice the length of the flagellomere.

Thorax: Brown in ground colour with white pruinosity; dorsocentrals 3+3; post-pronotals 1+2; scutellum yellow with one pair of basal setae; one pair of subapical setae and one pair of discal setae; pleura brown (except for yellow postpronotal lobe) with white pruinosity and long yellow setulae. Wing and calypter slightly infuscated, vein R 1 entirely setulose on dorsal surface and vein R 4+5 setulose from base to almost crossvein r-m on dorsal surface. Legs with coxa, trochanter, femur and tibia yellow; fore tarsus slightly brown and mid and hind tarsi brown; fore tibia with 1 strong posterior seta on middle third; 1 dorsal subapical seta; claws and pulvilli well developed; mid femur with 1 anterior seta on middle third; 3-5 long and sparse posteroventral setae on basal half; 1 posterodorsal subapical seta; mid tibia with 1 strong anterodorsal and 1 strong ventral seta on middle third each; 2 posterior setae on middle third; one posterodorsal row of short setae; 1 anterodorsal, 1 dorsal and 1 posterodorsal subapical seta each; 1 anteroventral, 1 ventral and 1 posteroventral apical seta each; hind femur with 2 anterodorsal setae on apical third; 5-7 sparse anteroventral setae on basal half; 1 anteroventral apical seta; hind tibia with 3-4 ventral setae on middle third; 1 posterodorsal and 1 anterodorsal subapical seta each; 1 posteroventral apical seta.

Abdomen: Yellow; T 1+2 not excavate to its hind margin; with a brown stripe not straight from T 1+2 to T 4, T 4 with a large transversal brown band on the posterior margin; one pair of median marginal setae on T 3.

Male terminalia: Sternite 5 square with a “ V ” shaped median cleft and with brown areas around setae and setulae insertions ( Fig. 23 ). Cerci not fused at the apical half ( Fig. 24 ) and slightly curved inward at tip ( Fig. 25 ); surstylus shorter than cercus with short setulae on the apical half; distiphallus with lateral arms short; postgonite narrow in lateral view and pregonite triangular in lateral view ( Fig. 26 ).

Female: Differs from male as follows: frons with 0.25 of head width at the level of the anterior ocellus; 2 pairs of reclinate orbital setae and 2 pairs of proclinate orbital setae; palpus slightly clavate; claws and pulvilli short.

Type material: Holotype male. BRAZIL. SP, São Paulo, Vila Ema ( MZSP) . Paratypes, 1 male and 2 females, same data as holotype ( MZSP) .

Geographic distribution: Brazil.

Comments: Easily recognized by its short length (6.0-7.0 mm), palpus exceptionally long and filiform, a straight brown dorsal stripe which enlarges at the apical margin of each tergite from T 1+2 to T 4 and T 4 with a large transversal brown band on the posterior margin.
