Trichomyia sinuosa Araújo & Bravo sp. nov.

( Figs. 41A–F )

Diagnosis. Basal expansion with a group of bristles on gonocoxite; sinuous arm of gonocoxite, C-shaped; two pairs of sclerotized projections in the aedeagal complex; one pair trifurcate, claw-shaped and one pair 1.3 times the length of aedeagus; ejaculatory apodeme short, 0.7 times the length of aedeagus.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape subcylindrical; pedicel subspherical; flagellomeres pyriform; ascoids 1.4 times as long as the length of flagellomere ( Fig. 41A ); 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 41D ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.7 ( Fig. 41B ). Wing: apex of Sc unsclerotized; R4+5 with base unsclerotized; r-m unsclerotized and m-cu absent ( Fig. 41C ). Male terminalia: Hypandrium and gonocoxites fused with a basal expansion with a group of bristles. Arm of gonocoxite very long tapering, C-shaped with a row of setulae. Gonostylus not visualized. Aedeagal complex with two pairs of sclerotized projections; one pair trifurcate, claw-shaped, and one pair 1.3 times the length of the aedeagus. Aedeagus with rounded tip, subtriangular ( Fig. 41F ). Ejaculatory apodeme short, 0.7 times the length of aedeagus. Epandrium with posterior margin larger than the anterior margin. Cercus angular with lateroapical bristles. Hypoproct with apical micropilosity. Epiproct subtriangular with rounded tip ( Fig. 41E ).

Female. Unknown.

Material examined. Brazil, Amazonas, Manacapuru, Cajatuba Km 69/3, 09.X.1998, holotype ♂, without

name of colector. ( MZFS); 3 paratypes: 2 ♂, same locality, date as holotype. ( MZFS); 1 ♂, Pará, Novo

Reparttimento, Vic. Bandeirante, Ramal dos sem terra, 22.VIII.1998, without name of colector ( MZFS). Etymology. The epithet sinuosa is allusive to the shape of arm of gonocoxite. Distribution. Brazil—Amazonas, Pará.
