Trichomyia pua Araújo & Bravo sp. nov.

( Figs. 39A –I)

Diagnosis. Basal sclerotized curved expansion on gonocoxite; two pairs of arms of gonocoxites, one triangular with apical setulae and the digitiform ventral with rounded apex and a row of rod-like setae; one pair of subtriangular projection of aedeagal complex; fused apically envolving the aedeagus as a hood; ejaculatory apodeme twice the length of gonostylus; cercus with an apical expansion with two setulae.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical; basal flagellomeres pyriform and eccentric; ascoids 2.0 times as long as the length of flagellomere, annulated ( Fig. 39A ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.5 ( Fig. 39B ). Wing. R2 with base unsclerotized; R4+5 incomplete at base; r-m and m-cu absent ( Fig. 39C ). Male terminalia: Hypandrium and gonocoxites fused with a basal sclerotized curved expansion. Two pairs of arms of gonocoxites, one digitiform, with rounded apex and a row of rod-like setae ( Fig. 39G ) and other triangular with an apical bristle, shorter than the dorsal. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, truncated. Presence of one pair of subtriangular projection of aedeagal complex; fused apically envolving the aedeagus as a hood. One pair of parameres digitiform and projected laterally. Aedeagus bifid with truncated apex ( Figs. 39E, 39H ). Ejaculatory apodeme twice the length of gonostylus. Epandrium wider than long, pilose. Cercus subtriangulares in lateral view with an apical expansion with two setulae ( Fig. 39D ). Hypoproct with apical micropilosity. Epiproct subcircular and membranous ( Fig. 39F ).

Female. Unknown.
