Trichomyia bifurcata Araújo & Bravo  sp. nov.

( Figs. 18 AView FIGURES 18 A – F –G)

Diagnosis. M 2 with base unsclerotized; r-m unsclerotized; two basal expansions on gonocoxite, the dorsal side expanded basally, with divergent apex; the ventral side with narrow tip, curved medially; arm of gonocoxite bifurcate with elongated bristles at apex; cercus terminally expanded with two apical setae.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical; flagellomeres pyriform and eccentric; ascoids 1.25 times as long as the length of flagellomere ( Fig. 18 AView FIGURES 18 A – F). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0: 0.5: 0.6 ( Fig. 18 BView FIGURES 18 A – F). Wing. R 4 + 5 with base unsclerotized; M 2 with base unsclerotized; r-m unsclerotized and m-cu absent ( Fig. 18 CView FIGURES 18 A – F). Male terminalia: Hypandrium and gonocoxites fused with two basal expansions, the dorsal side expanded basally, with divergent apex; the ventral side with narrow tip, curved medially ( Fig. 18 DView FIGURES 18 A – F). Arm of gonocoxite bifurcate with elongated bristles ( Fig. 18View FIGURES 18 A – F G). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, near to the base, bare, subtriangular ( Figs. 18 D, 18View FIGURES 18 A – F G). Presence of one pair of triangular projections in the aedeagal complex. Aedeagus bifid (18 G). Ejaculatory apodeme 0.8 times the length of gonostylus. Epandrium subquadrate. Cercus digitiform ( Figs. 18 E, 18 FView FIGURES 18 A – F) with an expansion with two apical setae ( Fig. 18 EView FIGURES 18 A – F). Hypoproct with apical micropilosity ( Fig. 18 FView FIGURES 18 A – F).

Female. Unknown.
