Trichomyia bahiensis Araújo & Bravo sp. nov.

( Figs. 16A–I )

Diagnosis. Gonocoxite arm lobe-like, upright in lateral view and with few short spinform bristles in the medial surface; gonostylus plate-like; one pair of projections in the aedeagal complex connected/joined by a thin ventral membrane; ejaculatory apodeme short, 0.4 times the length of gonocoxite; cercus with few small spatulate bristles near the apex.

Description. Male. Head subcircular in frontal view. Antenna: scape subcylindrical, pedicel subspherical; flagellum with 13 flagellomeres, 1st to 12th flagellomeres pyriform and eccentric ( Fig. 16A ); 13th flagellomere subcylindrical with terminal apiculus separated by suture ( Fig. 16C ); ascoids 1.1 times the length of a flagellomere ( Fig. 16B ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.7 ( Fig. 16D ). Wing. R4+5 incomplete at base; r-m and m-cu absent ( Fig. 16E ). Male terminalia: Hypandrium and gonocoxites fused. Gonocoxites with arm lobe-like, upright in lateral view and with few short spinform bristles in the medial surface ( Figs. 16G, 16I ). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, plate-like. Presence of one pair of projections in the aedeagal complex ending at the same level of aedeagus, united by a thin ventral membrane. Aedeagus filiform ( Figs. 16G, 16H ). Ejaculatory apodeme short, 0.4 times the length of gonocoxite. Epandrium with posterior margin larger than the anterior margin. Cercus ovoid ( Figs. 16F, 16H ); dorsal surface of cercus with few small spatulate bristles near the apex ( Fig. 16H ). Hypoproct with apical micropilosity ( Fig. 16F ).

Female. Unknown.
