description: Monohelea barbara Felippe-Bauer & Trindade sp. nov.
(Figs.1; 2 A–G; 9A–B)
Diagnosis. The only Neotropical species of Monohelea in which the males have brown legs with yellowish bands, two process in distal portion of the paramere, one beak-shaped and the other hook-shaped. Female unknown.
Male. Head: eyes widely separated (Fig. 2 C). Antenna brown; flagellomeres 1–13 with lengths 108- 35- 35- 35- 30- 30- 28- 28- 25- 38- 93- 95- 110 (Fig. 2 B). Antenal ratio 0.93. Palpus (Fig. 2 D) pale brown; 3rd segment nearly oval with small, shallow, sensory organ on mid length; palpal ratio 1.25.
Thorax. Without definite pattern on slide mounted specimen. Legs (Fig. 2 E) pale brown; fore-, mid coxae and trochanters brown; hind coxa and trochanter missing; femora with mesal and apical yellowish bands; hind femur with a brown ventral spot in the apical yellowish band; tibiae with basal and mesal yellowish bands; tibiofemoral joints yellowish; hind tibial comb with 7 bristles. Tarsi: pale; fore-, hind tarsomere 1 with one basal, one apical spine; midtarsomere 1 with 2 basal, 2 apical spines; apical spines of tarsomeres 2-4 of fore-, mid legs: 1-1-1, 2-2-2, basal spines absent; tarsomeres 2-4 of hind leg, missing; fore-, mid tarsal ratios 2.16, 2.43; claws small, paired, equal-sized, 0.35-0.39X as long as 5th tarsomeres. Wing (Fig. 2 A): macrotrichia restricted to vein costa; microtrichia absent; 2nd radial cell nearly 1.8X longer than 1st; wing length 0.83 mm, width 0.33 mm; costal ratio 0.75. Halter missing.
Abdomen. Brown (Fig. 2 F). Genitalia (Figs. 2 G; 9 A–B): 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 straight 0.60 as long as gonocoxite, moderately pilose on basal 3/4. Parameres swollen (Fig. 9A) 1.3X as long as aedeagus, largely fused dorsally at base; apical portion with two process laterally directed, similar in length, one beak-shaped, the other hook-shaped. Aedeagus (Fig. 9B) 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; basal arms slender, not expanded laterally.
Female. Unknown
Distribution. Brazil, Pará State.
Type. Holotype male, on microscope slide labeled “Fazenda Morelândia (01°11’43”S, 48°15’35”W), Santa Bárbara do Pará, Pará, BRASIL, 21–22.IX.2008, CDC light trap, Igarapé Baiacú, Trindade R.L. & Guimarães D. cols. (MPEG).
Etymology. This species is named based on the Muncipality of Santa Bárbara do Pará, where the specimen was collected.
Taxonomic discussion. Monohelea barbara most closely resembles M. roraimensis Felippe-Bauer, M. gorayebi sp.nov. and M. visinensis sp.nov. by the brown legs with yellowish bands and by the presence of two apical processes in the paramere. However, one apical process of the paramere is beak-shaped and other hookshaped, similar in lenght, laterally directed (both processes are hook-shaped, one 2X longer than other, laterally directed in M. gorayebi; one process is beak-shaped, laterally directed, and other bilobed internally directed, different in length in M. roraimensis; one process is hook-shaped laterally directed, and other aculeated, anteroventraly directed in M. visinensis); by the basal arms of the aedeagus slender, not expanded laterally (basal arms large, greatly expanded laterally in M. gorayebi; basal arms slender, slightly expanded laterally in M. visinensis).
