Trichomyia amazonensis Araújo & Bravo View in CoL sp. nov.

( Figs. 27–32 View FIGURES 27 – 32 )

Diagnosis. Gonocoxite with posterior arm short, with approximately nine rod-like setae in a row. Gonostylus with apex curved upward, almost the same size as the arm of the gonocoxite. One pair of parameres present, bifurcate, with the internal tip larger and thicker than the external one.

Description. Male. Head subcircular. Antenna incomplete in the specimens studied; scape shorter than pedicel ( Fig. 27 View FIGURES 27 – 32 ); basal flagellomeres pyriform, eccentric ( Fig. 27 View FIGURES 27 – 32 ), ascoids S-shaped, only observed in one paratype, 1.5 times as long as the flagellomere. Palpus formula 1.0:0.6:0.5 ( Fig. 29 View FIGURES 27 – 32 ). Wing ( Fig. 28 View FIGURES 27 – 32 ): Apex of Sc and sc-r unsclerotized; R5 incomplete at base; base of M2 and M3 unsclerotized; r-m and m-cu absent. Elongate bristles of tergum 7 with straight apices ( Fig. 31 View FIGURES 27 – 32 ). Male terminalia: Hypandrium and gonocoxites fused ( Fig. 31 View FIGURES 27 – 32 ). Gonocoxites with short posterior arm, apical margin with row of nine rod-like setae. Gonostylus, short, with apex curved upward ( Fig. 31 View FIGURES 27 – 32 ). One pair of parameres present, bifurcate, sclerotized, external arm shorter than internal arm ( Fig. 31 View FIGURES 27 – 32 ). Aedeagus short, subtriangular ( Fig. 31 View FIGURES 27 – 32 ). Ejaculatory apodeme long, 4.5 times the length of the gonostylus ( Fig 31 View FIGURES 27 – 32 ). Epandrium with posterior margin wider than anterior margin, wider than long ( Fig. 32 View FIGURES 27 – 32 ); cercus pilose, subrectangular ( Figs. 30, 32 View FIGURES 27 – 32 ). Hypropoct triangular ( Fig. 32 View FIGURES 27 – 32 ).

Disribution. Known from Novo Repartimento in Pará, Brazil, Presidente Figueiredo and Manacapuru in Amazonas, Brazil, and Pitinga in Roraima, Brazil.

Etymology. amazonensis based on the type locality.

Comments. T. amazonensis is easily distinguished from the other species of Septemtrichomyia by its bifurcate parameres, and by the apical position of the row of rod-like setae on the posterior arms of the gonocoxite. These rods are situated on the lateral margins of the posterior gonocoxite arms in other species of the subgenus.
