Trichomyia colligata Araújo & Bravo sp. nov.

( Figs. 21A–F )

Diagnosis. M2 with base unsclerotized; r-m unsclerotized; arm of gonocoxite bifurcate, with bristles on the two projections; one pair of subtriangular projections in the aedeagal complex; with divergent apex; ejaculatory apodeme 1.4 times the length of gonostylus, cercus with apical expansion with two elongated rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical; flagellomeres pyriform and eccentric, with many lateral bristles in dorsal view; ascoids 1.4 times longer than a flagellomere ( Fig. 21A ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.4:0.3 ( Fig. 21B ). Wing. R4+5 with base unsclerotized; M2 with base unsclerotized; r-m unsclerotized and m-cu absent ( Fig. 21C ). Male terminalia: Hypandrium and gonocoxites fused with a pair of subtriangular expansion. Arm of gonocoxite bifurcate, with bristles on the two projections. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, triangular. Presence of one pair of subtriangular projections in the aedeagal complex; with divergent apexices/tips. Aedeagus subtriangular reaching to the middle of the projections in the aedeagal complex ( Fig. 21F ). Ejaculatory apodeme 1.4 times the length of gonostylus. Epandrium pilose, longer than wide. Cercus piriform ( Fig. 21E ) with apical expansion with two elongated rod-like bristles ( Fig. 21D ). Hypoproct with apical micropilosity ( Fig. 21E ).

Female. Unknown.

Material examined. Brazil, Roraima, Pitinga, 13–15.XI.1997, holotype ♂, RQ, RN, PE leg. ( MZFS); 6 paratypes: 4♂, same locality, date and collectors as holotype ( INPA); 2 ♂, Pará, Novo Repartimento, Vic. Bandeirante, Sítio Pedro Roqueta, 19.VIII.1998, without name of collector ( MZFS).
