Trichomyia anira Araújo & Bravo sp. nov.

( Figs. 2A–I )

Diagnosis. Ascoids annulated, apex of Sc unsclerotized, sc-r unsclerotized, R4+5 with base unsclerotized; one pair of dorsal expansion hook-shaped on gonocoxite; one pair of sclerotized projection of aedeagal complex, lanceolate in the apex and fused U-shaped basally; cercus with an expansion with apical bristles.

Description. Male. Head subcircular in frontal view. Antenna with scape subcylindrical; pedicel subspherical; flagellomeres piriform and eccentric; ascoids 1.8 times as long as the length of flagellomere, annulated ( Fig. 2B ). 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 2C ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.6 ( Fig. 2A ). Wing. apex of Sc unsclerotized, sc-r unsclerotized, R4+5 with base unsclerotized; r-m and m-cu absent ( Fig. 2E ). Male terminalia: Hypandrium and gonocoxites fused with one pair of dorsal expansion hook-shaped, with thin tip. Arm of gonocoxite digitiform with an elongated bristle laterobasal. Gonostylus lightly sclerotized, articulated ventrally to gonocoxite, bare and with expanded base ( Figs. 2H, 2I ). Aedeagal complex with one pair of sclerotized projection, fused at apex, L-shaped and fused basally, U-shaped, involving the aedeagus. Aedeagus expanded apically. Ejaculatory apodeme long, 1.6 times the length of gonostylus ( Fig. 2G ). Epandrium longer than wide ( Figs. 2F, 2I ). Cercus digitiform with an expansion with five apical bristles with curved apex ( Fig. 2D ). Hypoproct tapering with apical micropilosity ( Fig. 2F ).

Female. Unknown.
