Trichomyia aquita Araújo & Bravo sp. nov.

( Figs. 14A–G )

Diagnosis. Hypandrium and gonocoxites fused, with a basal expansion curved, directed medially; arm of gonocoxite directed dorsally with elongated bristles; two pairs of sclerotized projections in the aedeagal complex; the lateral digitiform, about the same length as the inner, the inner fused, cup-shaped; ejaculatory apodeme 3.0 times the length of gonostylus.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape and pedicel subcylindrical; basal flagellomere pyriform and eccentric ( Fig. 14A ); ascoids 1.3 times as long as the length of flagellomere ( Fig. 14B ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.6 ( Fig. 14C ). Wing. Base of R s unsclerotized; r-m and m-cu absent (14D). Male terminalia: Hypandrium and gonocoxites fused with a basal expansion, curved and medially directed. Arm of gonocoxite directed dorsally with elongated bristles ( Fig. 14E ); gonostylus slightly sclerotized, articulated ventrally to gonocoxite, subtriangular, bare with rounded apex. Aedeagal complex with two pairs of sclerotized projections; the lateral digitiform, about the same length as the inner, the inner fused, cup-shaped. Aedeagus simple ( Fig. 14G ). Ejaculatory apodeme 3.0 times the length of gonostylus. Epandrium longer than wide. Cercus pilose and piriform. Hypoproct with apical micropilosity ( Fig. 14F ).

Female. Unknown.

Material examined. Brazil, Amazonas, Presidente Figueiredo, Pitinga, 04.XII.1998, holotype ♂, RQ, LMC leg. ( MZFS) 4 paratypes: 2 ♂, same locality, date and colectors as holotype, ( MZFS); 2 ♂, same locality as holotype, 15.XIII.1998, RR, LMS leg. ( INPA)

Etymology. From tupi-guarani aquitã = short, refers to the length of the arm of gonocoxite.

Distribution. Brazil—Amazonas.
