Trichomyia confusa Araújo & Bravo  sp. nov.

( Figs. 11 A –IView FIGURES 11 A – 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. 11 AView FIGURES 11 A – I), 13 th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 11 EView FIGURES 11 A – I). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0: 0.6: 0.6 ( Fig. 11 BView FIGURES 11 A – I). Wing. R 4 + 5 complete at base; r-m present and m-cu absent ( Fig. 11 DView FIGURES 11 A – I). 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. 11 IView FIGURES 11 A – I). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, truncated, small and wide ( Fig. 11 FView FIGURES 11 A – I). 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. 11 CView FIGURES 11 A – I). Ejaculatory apodeme short, the same length as gonostylus. Epandrium pilose, subquadrangular ( Fig. 11 HView FIGURES 11 A – I). Cercus piriform with a row of five apical rod-like setae, in dorsal view ( Fig. 11 GView FIGURES 11 A – I). Hypoproct with apical micropilosity ( Fig. 11 HView FIGURES 11 A – I).

Female. Unknown.
