Trichomyia inedita Araújo & Bravo sp. nov.

( Figs. 29A–I )

Diagnosis. Apex of Sc unsclerotized; M2 with base unsclerotized; hypandrium involving the aedeagus, with a subspherical dorsal projection; arm of gonocoxite elongated coated laterally by bristles and apically by two setae; one pair of projections in the aedeagal complex; involving the aedeagus, curve-shaped; ejaculatory apodeme short, 1.25 times the length of gonostylus; cercus with apical rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape and pedicel subspherical; flagellomeres pyriform and eccentric ( Fig. 29A ); ascoids 1.3 times as long as the length of flagellomere; 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 29G ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.8 ( Fig. 29B ). Wing. apex of Sc unsclerotized; sc-r unsclerotized; R4+5 with base unsclerotized; M2 with base unsclerotized, r-m unsclerotized and m-cu absent ( Fig. 29D ). Male terminalia: Hypandrium and gonocoxites fused, hypandrium involving the aedeagus, with a dorsal subspherical projection ( Figs. 29F, 29H ). Gonocoxites with elongate arm coated laterally with bristles and apically with two setae. Gonostylus unsclerotized, subtriangular. Presence of one pair of projections in the aedeagal complex; involving the aedeagus, curved-shaped. Aedeagus with expanded and rounded apex ( Fig. 29F ). Ejaculatory apodeme short, 1.25 times the length of gonostylus. Epandrium subcircular; elongated cercus, digitiform, with rod-like bristles in the ventral surface of the apex, about five ( Fig. 29E, 29I ). Hypoproct tapering apically with apical micropilosity and expanded basally. Epiproct triangular with pointed apex ( Figs. 29H, 29I ).

Female. Unknown.

Etymology. The epiteht is allusive to the different shaped of hypandrium that involving the aedeagus, with a subspherical projection, characteristic totally different from other species of the genus.

Distribution. Brazil—Amazonas, Pará.

Remarks. The right palpus of holotype has a mutation, with the two last segments fused ( Fig. 29C ).
