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.

Trichomyia aquita
sp. nov.
A. Scape, pedicel and basal flagellomere; B. Flagellomere with ascoids; C. Palpus; D. Right wing; E. Arm of gonocoxite, lateral; F. Cerci, epandriuma and hypropoct; G. Male terminalia, dorsal (abbreviations: aed = aedeagus, ag = arm of gonocoxite, bs = basal expansion, gst = gonostylus, I, II pac = projections in the aedeagal complex I and II).
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 (
