Trichomyia elongata Araújo & Bravo sp. nov.

(Figs. 25A–I)

Diagnosis. R4+5 complete at base; r-m present; arm of gonocoxite directed to midline, apically bifurcated and with a group of elongated bristles in the center; one pair of lanciform projections in the aedeagal complex; aedeagus ending after the apex of projections in the aedeagal complex; ejaculatory apodeme short, 0.5 times the length of medial expansion of gonocoxite; cercus with apical projection with two setae.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape about the same length as the subspherical pedicel; flagellomeres pyriform, eccentric (Figs 25A, 25B); basal ascoids 1.7 times the length of flagellomere (Fig. 25D); 13th flagellomere subcylindrical with terminal apiculus separated by a suture (Fig. 25B). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.9:0.9 (Fig. 25C). Wing. R4+5 complete at base; r-m present; m-cu absent (Fig. 25E). Male terminalia: Hypandrium fused with gonocoxites with a pair of medial lanciform expansion. Gonocoxites with posterior arm directed to midline, apically bifurcate and with a group of elongated bristles in the center. Gonostylus articulated to gonocoxite at the middle, bare, with apex directed upward (Fig. 25G). Projections in the aedeagal complex, one pair, lanciform. Aedeagus ending after the apex of projections in the aedeagal complex (Fig. 25H). Ejaculatory apodeme short, 0.5 times the length of medial expansion of gonocoxite. Epandrium pilose, posteriorly wider than anteriorly. Cercus pilose, piriform, with apical elongated projection with two setae (Figs. 25G, 25I). Epiproct shorter than hypoproct, both with apical micropilosity (Fig. 25G).

Female. Unknown.
