( Figs. 18A –G) Diagnosis. M2 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. FIGURES 18A–F. Trichomyia bifurcata sp. nov. A. Scape, pedicel and basal flagellomeres; B. Palpus; C. Right wing; D. Male terminalia, lateral; E. Cercus, in lateral view; F. Cerci, epandrium and hypropoct; G. Male terminalia, dorsal. 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. 18A ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.6 ( Fig. 18B ). Wing. R4+5 with base unsclerotized; M2 with base unsclerotized; r-m unsclerotized and m-cu absent ( Fig. 18C ). 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. 18D ). Arm of gonocoxite bifurcate with elongated bristles ( Fig. 18 G). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, near to the base, bare, subtriangular ( Figs. 18D, 18 G). Presence of one pair of triangular projections in the aedeagal complex. Aedeagus bifid (18G). Ejaculatory apodeme 0.8 times the length of gonostylus. Epandrium subquadrate. Cercus digitiform ( Figs. 18E, 18F ) with an expansion with two apical setae ( Fig. 18E ). Hypoproct with apical micropilosity ( Fig. 18F ). Female. Unknown. Material examined.

The epithet bifurcata is allusive to the large number of bifurcated structures (arm of gonocoxite, aedeagus) Distribution. Brazil—Amazonas, Pará.
