Trichomyia mineira Araújo & Bravo sp. nov.

( Figs. 33A–E )

Diagnosis. R4+5 complete at base; medial posterior expansion on gonocoxite, bifurcated apically; two arms of gonocoxite, the dorsal shorter than ventral, with three elongated bristles; the ventral with a row of elongate bristle on dorsal surface; ejaculatory apodeme short, twice the length of gonostylus; cercus with three apical rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape as long as the subspherical pedicel; 1st flagellomere pyriform; posterior flagellomeres pyriform and eccentric ascoids 1.6 times the length of flagellomere ( Fig. 33A ). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.7 ( Fig. 33B ). Wing. R4+5 complete at base; r-m and m-cu absent ( Fig. 33C ). Male terminalia: Hypandrium fused with gonocoxites with medial posterior expansion, bifurcated apically. Gonocoxites with two arms, the dorsal shorter than ventral and directed to the midline; the apex of dorsal arm with three elongated bristles; the ventral arm with a row of elongated bristle in the dorsal surface. Gonostylus digitiform. Projections in the aedeagal complex, two pair, with approximately the same length. Aedeagus ending at the same level of projections in the aedeagal complex ( Fig. 33E ). Ejaculatory apodeme short, twice the length of gonostylus. Epandrium pilose, wider than long. Cercus pilose, piriform with short apical and thick bristles. Hypoproct, sharp apex with apical micropilosity ( Fig. 33D ).
