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

( Figs. 1 View FIGURE 1 ; 4 A–G; 9 E–F)

Diagnosis. The only Neotropical species of Monohelea in which the males have hind femur with brown base, mid leg with distinct mesal brown bands, paramere with mesal hook-shaped process measuring 0.61X as long as distal portion that progressively narrows distally to rounded apex. Female unknown.

Male. Head: eyes widely separated ( Fig. 4 C View FIGURE 4 ). Antenna missing. Palpus ( Fig. 4 D View FIGURE 4 ) pale brown; 3rd segment nearly oval with small, shallow, sensory organ on apical 1/3; lengths of segments 20- 25- 25- 25- 43; palpal ratio 1.25.

Thorax. Brown; scutum damaged. Legs ( Fig. 4 F View FIGURE 4 ) yellow; fore leg missing, mid-, hind coxae and trochanters brown; mid femur with basal and mesal pale brown bands, hind femur with basal brown band, one brown stripe in middle, a subapical ventral brown spot; mid tibiae with a mesal and apical pale brown band; hind tibia missing. Tarsi: mid tarsomere 1 with 2 basal, 2 apical spines; mid tarsomeres 2–4 with 2-2-2 apical spines, basal spines absent; mid tarsomere 5 missing; mid tarsal ratio 2.22; claws missing. Wing ( Fig. 4 A View FIGURE 4 ) partially damaged; macrotrichia restricted to vein costa; microtrichia absent; 2nd radial cell nearly 2X longer than 1st; wing length nearly 0.90 mm, width 0.34 mm; costal ratio nearly 0.75. Halter stem pale; knob pale brown in distal 1/2, a pale brown spot laterally ( Fig 4 B View FIGURE 4 ).

Abdomen. Pale brown ( Fig. 4 E View FIGURE 4 ). Genitalia ( Figs. 4 G View FIGURE 4 ; 9 E–F): sternite IX spiculate except on basal portion, posterior margin with a short, convex, median lobe with 4 long setae; tergite IX tapering with a pair of apicolateral processes. Gonocoxite moderately stout, nearly 1.8 X longer than basal width; gonostylus curved in apical 1/2, 0.59 as long as gonocoxite, moderately pilose on basal 3/4. Parameres ( Fig. 9 E View FIGURE9 ) 1.36 X as long as aedeagus, broadly fused at trilobed base; each with a long, curved, sclerotized mesal hook-shaped process, 0.61X as long as distal portion of the paramere, that tapering gradually to blunt apex. Aedeagus ( Fig. 9 F View FIGURE9 ) 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.
