Monohelea patauateua Felippe-Bauer & Trindade View in CoL sp. nov.

( Figs. 1 View FIGURE 1 ; 7 A–H; 10 C–D)

Diagnosis. Only Neotropical species of Monohelea with following combination of features: legs yellowish, hind femur with brown base, mid leg without distinct mesal brown marks. Males: paramere single, slender and flattened without mesal or apical process.

Male. Head: eyes widely separated ( Fig. 7 E View FIGURE7 ). Antenna yellowish brown with pedicel darker; flagellomeres 1– 13 with lengths 98- 30- 30- 30- 28- 28- 25- 28- 25- 38- 93- 98- 98 ( Fig. 7 C View FIGURE7 ). Antennal ratio 1.01. Palpus yellowish brown; 3rd segment nearly oval with small, shallow, sensory organ on mid portion; lengths of segments 15- 25- 30- 25- 43; palpal ratio 1.7-1.8 (1.7, n=2).

Thorax. Without definite pattern on slide mounted specimens. Legs ( Fig. 7 F View FIGURE7 ) yellow; coxae and trochanters brown; fore femora with basal brown bands and mesal brown stripe, mid femur with basal brown band, hind femur with basal brown band, mesal brown stripe and subapical ventral brown spot; tibiae brown apically; hind tibia with a subbasal ventral brown spot, brown stripe in middle; hind tibial comb with 5–6 bristles. Tarsi: pale; fore-, hind tarsomere with one basal and one apical spine; mid tarsomere 1 with 1–2 (usually 2) basal and 2 apical spines; apical spines of tarsomeres 2–4 of fore-, mid-, hind legs: 1-1-1 or 2-2-2, 2-2-2, 1-1-1, basal spines absent; fore tarsal ratio 2.06–2.25 (2.19, n=4), mid tarsal ratio 2.34–2.36 (2.35, n=2), hind tarsal ratio 2.00 (n=3); claws small, paired, equal-sized, 0.41–0.47 (n=3)X as long as 5th tarsomeres. Wing ( Fig. 7 A View FIGURE7 ): macrotrichia restricted to vein costa; microtrichia absent; 2nd radial cell nearly 1.9X longer than 1st; wing length 0.81–0.82 (0.82, n=4) mm, width 0.29–0.31 (0.30, n=4) mm; costal ratio 0.75–0.79 (0.76, n=4). Halter stem pale; knob pale brown in distal 1/2, a pale brown spot laterally ( Fig. 7 D View FIGURE7 ).

Abdomen. Yellowish brown. Genitalia ( Figs. 7 G View FIGURE7 ; 10 C–D): sternite IX spiculate except on basal portion, posterior margin not defined; tergite IX tapering with a pair of apicolateral processes, each with 4 setae. Gonocoxite moderately stout, nearly 2X longer than basal width; gonostylus brown, slender, slightly curved 0.55– 0.60 (0.58, n=5) as long as gonocoxite, moderately pilose on basal 3/4. Parameres ( Fig. 10 C View FIGURE 10 ) 1.35–1.55 (1.42, n= 5) X as long as aedeagus, narrowly fused at trilobed base; stem slender flattened, tapering to apex. Aedeagus ( Fig. 10 D View FIGURE 10 ) triangular, composed of 2 pointed ventral plates, each with only delicately sclerotized apical projection, which arises in the middle way to aedeagus base, and produced beyond the apices of ventral plates, ending as an apical projection; basal arms slender, slightly expanded laterally.

Female. Similar to male with usual sexual differences; eyes contiguous; antenna missing; palpal ratio 1.75; mandible with 10 teeth. Wing ( Fig. 7 B View FIGURE7 ) length 0.86 mm; width 0.35 mm; costal ratio 0.80. Legs as in male; fore-, mid-, hind tarsal ratios 2.22, 2.56, 2.14; fore-, mid claws about 0.70X as long as 5th tarsomeres, hind claw 1.45X as long as 5th tarsomere. Two unequal spermathecae ( Fig. 7 H View FIGURE7 ), measuring 68 by 60 µm and 40 by 40 µm, the larger one with sclerotized neck with 12,5 µm.

Distribution. Brazil, Pará State.

Types. Holotype male, on microscope slide labeled “Fazenda Gavião Real (01°29’44”S, 47°13’07”W), Vila de Patauateua, Ourém, Pará, BRASIL, 29–30.XI.2008, CDC light trap, Forest, Trindade R.L. & Guimarães D. cols. (MPEG). Allotype female: same data as holotype (MPEG). Paratypes, 4 males: same data as holotype (2 MPEG; 2 CCER).

Etymology. This species is named after the type locality.
