Trichomyia confusa Araújo & Bravo sp. nov.

( Figs. 11A–I )

Diagnosis. Hypandrium and gonocoxites fused forming a wide dorsal plate; two pairs of arms, the dorsal longer and wider than the ventral, curved, directed dorsally, with elongated bristles and apical setae, ventral arm curved, medially directed, bare and with pointed apex; gonostylus wide; ejaculatory apodeme short, the same length as gonostylus; cercus piriform with an apical row of rod-like setae.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape subcylindrical; pedicel subspherical; basal flagellomeres pyriform and centric; ascoids 1.4 times as long as the length of flagellomere ( Fig. 11A ), 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 11E ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.6 ( Fig. 11B ). Wing. R4+5 complete at base; r-m present and m-cu absent ( Fig. 11D ). Male terminalia: Hypandrium and gonocoxites fused forming a wide dorsal plate. Gonocoxites with two pairs of arms, the dorsal longer and wider than the dorsal, curved, directed dorsally, with elongated bristles and apical setae, about three. Ventral arm curved, medially directed, bare and with pointed apex( Fig. 11I ). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, truncated, small and wide ( Fig. 11F ). Presence of three pairs of projections in the aedeagal complex; one sclerotized pair, curved and with tip directed distally, and the other two little sclerotized, with the same origin but different directions, one thinner, the other thicker than the sclerotized. Aedeagus ending at middle portion of projections in the aedeagal complex ( Fig. 11C ). Ejaculatory apodeme short, the same length as gonostylus. Epandrium pilose, subquadrangular ( Fig. 11H ). Cercus piriform with a row of five apical rod-like setae, in dorsal view ( Fig. 11G ). Hypoproct with apical micropilosity ( Fig. 11H ).

Female. Unknown.

Material examined. Brazil, Amazonas, Manacapuru, Km 75, 25–27.VII.1997, holotype ♂, without name of collector ( MZFS); 6 paratypes: 1♂, same locality, date and collectors as holotype ( INPA); 1 ♂, same locality as holotype, Simplício, 74 km WSW of Manaus, 20.IV.1998, RQ, RN, PE leg. ( INPA); 2 ♂, Amazonas, Manaus, Reserva Ducke, 26–31.VIII.2011, M.X. Araújo leg. ( MZFS); 1 ♂, Amazonas, Estrada de Cajatuba, 24–29.X.1997, without name of collector ( INPA); 1 ♂, same locality as holotype, Km 69/3, 06.X.1998, without name of collector ( MZFS).

Etymology. The epithet confusa refers to the great complexity of projections in the aedeagal complex.

Distribution. Amazonas—Brazil.
