Trichomyia nortensis Araújo & Bravo sp. nov.

( Figs. 34A–K )

Diagnosis. R2 not reaching R3, r-m present; arm of gonocoxite with a row of six rod-like setae at apex; elongated gonostylus with apex medially directed; three pairs of fused projections in the aedeagal complex; one pair digitiform, with a row of apical setulae, one pair divergent apically, and one pair triangular, all joined by a membrane; ejaculatory apodeme short, as long as gonostylus.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape subcylindrical; pedicel subspherical; basal flagellomeres piriform ( Fig. 34A ); ascoids 1.25 times the length of flagellomere ( Fig. 34B ); 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 34I ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.9 ( Fig. 34C ). Wing. R2 not reaching R3, r-m present and m-cu absent ( Fig. 34E ). Male terminalia: Hypandrium and gonocoxites fused. Posterior arm of gonocoxites with mesal margin expanded medially, apices curved, directed ventromedially, with a row of six digitiform setae unserted apically and a row of apical bristles ( Figs. 34D, 34G ). Gonostylus ventrally to gonocoxite, elongated and with apex directed diagonally upward ( Figs. 34G, 34K ). Presence of three pairs of fused projections in the aedeagal complex; one pair digitiform, with a row of apical setulae, one pair directed diagonally and divergent apically, and one triangular pair horizontal disposed, all joined by a membrane ( Fig. 34H ). One pair of parameres with truncated apex ( Fig. 34J ). Ejaculatory apodeme short, the same length as gonostylus. Epandrium medially narrow. Cercus subquadrangular with bristles at apex, fused in a expanded plate medially. Hypoproct apically blunt, piriform with setulae ( Fig. 34F ).

Female. Unknown.
