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

( Figs. 1 View FIGURE 1 ; 8 A–E; 10 E–F)

Diagnosis. The only Neotropical species of Monohelea in which the males have brown legs, hind femur with two mesal yellowish bands, paramere with two pointed apical processes and a ventral, sclerotized oval structure, aedeagus with basal arms slender, slightly expanded laterally. Female unknown.

Male. Head: eyes widely separated. Antenna pale brown with pedicel darker; flagellomeres 1–9 with lengths 113- 35- 35- 33- 30- 30- 28- 30- 25, 38, 11-13 missing. Antennal ratio untold. Palpus ( Fig. 8 C View FIGURE 8 ) pale brown; 3rd segment compressed, nearly oval with large, moderately deep, sensory organ on distal 1/2; palpal ratio untold.

Thorax. Brown; scutum without definite pattern on slide mounted specimen; scutellum yellowish laterally, with 4 bristles. Legs ( Fig. 8 D View FIGURE 8 ) brown; coxae and trochanters brown; femora with two mesal yellowish bands; tibiofemoral joints yellowish; tibiae with subbasal and mesal yellowish bands; hind tibial comb with 6 bristles. Tarsi: pale; fore-, hind tarsomere 1 with one basal and one apical spine; midtarsomere 1 with 1 basal, 2 apical spines; apical spines of midtarsomeres 2–4: 1-1-1, basal spines absent; fore-, hind tarsomeres 2–4 missing; mid tarsal ratio 2.50; median claws small, paired, equal-sized, 0.4X as long as 5th tarsomeres. Wing ( Fig. 8 A View FIGURE 8 ): macrotrichia restricted to vein costa; microtrichia absent; 2nd radial cell damaged; wing length 0.81 mm, width 0.30 mm; costal ratio nearly 0.74. Halter stem pale; knob brown in distal 1/2 ( Fig. 8 B View FIGURE 8 ).

Abdomen. Brown. Genitalia ( Figs. 8 E View FIGURE 8 ; 10 E–F): sternite IX spiculate except on basal portion, posterior margin not defined; tergite IX tapering with a pair of apicolateral processes. Gonocoxite moderately stout, nearly 2X longer than basal width; gonostylus near straight 0.81 as long as gonocoxite, moderately pilose on basal 1/2. Parameres swollen ( Fig. 10 E View FIGURE 10 ) 1.08X as long as aedeagus, broadly fused at trilobed base; each with a ventral sclerotized oval structure bearing two sharp apical processes, one hook-shaped laterally directed and other aculeated anteroventraly directed. Aedeagus ( Fig. 10 F View FIGURE 10 ) triangular, composed of 2 pointed ventral plates, with slightly sclerotized dorsal structure, 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. Unknown

Distribution. Brazil, Pará State.

Type. Holotype male, on microscope slide labeled “Fazenda Ema (01°24’37”S, 46°22’12”W), Viseu, Pará, BRASIL, 23–24.VI.2007, CDC light trap, forest, Guimarães, D. col. ( MPEG).
