Trichomyia longa Araújo & Bravo sp. nov.

( Figs. 12A–H )

Diagnosis. Gonocoxites with two elongated arms, one pilose and one bare, both curved; aedeagal complex with two pairs of projections, the dorsal smaller than ventral projection, distally curved to the midline; ejaculatory apodeme short, 1.2 times the length of gonostylus, cercus with apical rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape shorter than the subspherical pedicel; flagellomeres pyriform ( Fig. 12B ); 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 12C ); ascoids paired, 1.4 times the length of flagellomeres ( Fig. 12A ). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.8 ( Fig. 12D ). Wing. R4+5 incomplete at base; r-m and m-cu absent ( Fig. 12E ). Male terminalia: Hypandrium fused with gonocoxites. Gonocoxites with two elongated arms, one pilose and one bare, both curved. Gonostylus articulated ventrally to gonocoxite, bare, subrectangular in lateral view ( Figs. 12F, 12H ). Aedeagal complex with two pairs of projections, the dorsal smaller than ventral; the dorsal projection distally curved to the midline. Aedeagus simple ( Fig. 12F ). Ejaculatory apodeme short, 1.2 times the length of gonostylus. Epandrium pilose, wider than long. Cercus pilose ( Fig. 12G ), subelliptical in lateral view with a group of apical, thick bristles. Hypoproct with apical micropilosity ( Fig. 12H ).

Female. Unknown.
