Trichomyia mariensis Araújo & Bravo sp. nov.

( Figs. 31A–H )

Diagnosis. R4+5 complete at base; hypandrium strip-like; long and lanciform prolongations on gonocoxite that cross between them at apex; arm of gonocoxite curved to the midline, pilose apically with row of small rod-like bristles; aedeagus long, approximately twice the length of projections in the aedeagal complex; cercus pilose with bifurcated apex.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape larger than pedicel; pedicel subspherical; basal flagellomeres, eccentric ( Fig. 31A ); ascoids 1.6 times the length of flagellomere ( Fig. 31C ). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.4 ( Fig. 31B ). Wing. R4+5 complete at base; r-m and m-cu absent ( Fig. 31D ). Male terminalia: Hypandrium strip-like ( Fig. 31H ). Gonocoxites with two long and lanciform prolongations that cross between them in the apex ( Fig. 31F ). Arm of gonocoxite curved to the midline, pilose apically with row of small rod-like bristles. Gonostylus articulated to gonocoxite at the middle, bare, small, triangular. One pair of gonocoxite wide, sclerotized ( Fig. 31H ). Aedeagus long, approximately twice the length of projections in the aedeagal complex ( Fig. 31E ). Ejaculatory apodeme short, 1.2 times the length of projections in the aedeagal complex. Epandrium pilose, subrectangular ( Fig. 31G ). Cercus pilose, bifurcated apex ( Figs. 31E, 31G ).
