Trichomyia conchulata Araújo & Bravo sp. nov.

( Figs. 23A–H )

Diagnosis. M2 not reaching M1, one pair of parameres with pointed apex; arm of gonocoxite with a row of nine rodlike bristles; one pair of subtriangular projections in the aedeagal complex; sclerotized; ejaculatory apodeme 1.15 times the length of gonostylus; aedeagus bifid, with tips united apically; epandrium subtriangular.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape subcylindrical; pedicel subspherical; basal flagellomeres pyriform and eccentric ( Fig. 23A ); ascoid about the same length as the flagellomere ( Fig. 23C ); 13th flagellomere subcylindrical with terminal apiculus separated by suture ( Fig. 23E ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.8:0.6 ( Fig. 23B ). Wing. R4+5 incomplete at base; M2 not reaching M1, r-m and m-cu absent ( Fig. 23D ). Male terminalia: Hypandrium and gonocoxites fused. One pair of parameres with pointed apex. Arm of gonocoxite curved and medially directed, with a row of nine rod-like bristles. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare. Aedeagal complex with one pair of sclerotized subtriangular projections. Aedeagus bifid, with tips united apically ( Figs. 23F, 23H ). Ejaculatory apodeme 1.15 times the length of gonostylus. Epandrium pilose, subtriangular, longer than wide. Cercus curved with apical bristles. Hypoproct with apical micropilosity and epiproct expanded basally, subtriangular/oval. Epiproct subtriangular, membranous and with rounded apex ( Figs. 23F, 23G ).
