Trichomyia grossa Araújo & Bravo sp. nov.

( Figs. 26A–F )

Diagnosis. R4+5 complete at base; lanceolate expansion on gonocoxite; two pairs of projections in the aedeagal complex, sclerotized medial and shorter than lateral; ejaculatory apodeme 1.5 the length of lateral projection of aedeagal complex.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape shorter than pedicel; pedicel subspherical; basal flagellomeres pyriform and eccentric; ascoids 1.3 times the length of flagellomere ( Fig. 26A ). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.6 ( Fig. 26B ). Wing. R4+5 complete at base; r-m and m-cu absent ( Fig. 26C ). Male terminalia: Hypandrium fused with gonocoxites with lanceolate ventral expansion ( Fig. 26F ). Gonocoxites with posterior arm subrectangular in lateral view with a row of basal bristles ( Figs. 26D, 26F ). Gonostylus articulated to gonocoxite basally, bare, with apex directed dowward. Projections in the aedeagal complex, two pairs, sclerotized medial and smaller than lateral. Aedeagus ending after the apex of medial projection of aedeagal complex. Ejaculatory apodeme 1.5 the length of lateral projection of aedeagal complex. Epandrium pilose, subrectangular ( Fig. 26E ). Cercus pilose ( Figs. 26D, 26E ), subelliptical in lateral view, larger basally than apically. Epiproct shorter than hypoproct, both with apical micropilosity ( Fig. 26D ).

Female. Unknown.
