Trichomyia ribeiroi Araújo & Bravo sp. nov.

( Figs. 40A–H )

Diagnosis. A pair of basal curved expansion on gonocoxite; arm of gonocoxite bifurcate, with apical and basal bristles; one pair of sclerotized curved projections in the aedeagal complex; ejaculatory apodeme long, 1.5 times the length of gonostylus; cercus with about four apical setae

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape and pedicel subspherical; basal flagellomeres pyriform and eccentric; ascoids 1.6 times as long as the length of flagellomere ( Fig. 40A ); 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 40C ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.7 ( Fig. 40B ).

Wing. Wings of paratypes have tip of sc unsclerotized; sc-r is unsclerotized; R4+5 incomplete at base; r-m and m-cu absent ( Fig. 40E ). Male terminalia: Hypandrium and gonocoxites fused with a pair of basal curved expansion, in dorsal view, fused apically. Arm of gonocoxite bifurcate, with apical and basal bristles. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, subtriangular. Presence of one pair of sclerotized curved projections in the aedeagal complex with apex directed laterally. Aedeagus simple, with a single opening ( Figs. 40G, 40H ). Ejaculatory apodeme long, 1.5 times the length of gonostylus. Epandrium subquadrangular pilose. Cercus pilose, expanded in the base and elongated, with about four apical setae. Hypoproct with apical micropilosity ( Fig. 40D ).

Female. Unknown.

Etymology. Named in honor of José Cláudio Ribeiro da Silva, defender environmentalist of Amazon, killed in 2011.

Distribution. Brazil—Amazonas, Pará.

Remarks. The wing of holotype has differentiated venation( Fig. 40F ); with Sc complete, without tip unsclerotized; sc-r present; and medial veins not connected. Furthermore, the wing is more elongated than the wings of paratypes.
