Trichomyia complicata Araújo & Bravo sp. nov.

( Figs. 22A–H )

Diagnosis. Gonocoxites with posterior arm tapering apically, anterior margin with a row of small rod-like setae; two pairs of digitiform projections in the aedeagal complex; the inner projection about twice longer than lateral projection; ejaculatory apodeme short, 0.3 times the length of gonostylus; cercus with two short apical bristles.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical ( Fig. 22A ); flagellomeres pyriform and eccentric ( Fig. 22A ); ascoids 1.8 times as long as the length of flagellomere ( Fig. 22C ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.6 ( Fig. 22B ). Wing. R4+5 incomplete at base; r-m and m-cu absent ( Fig. 22D ). Male terminalia: Hypandrium and gonocoxites fused. Gonocoxites with posterior arm tapering apically; anterior margin with a row of small rod-like setae ( Fig. 22G ). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, curved ( Figs. 22G, 22E ). Presence of two pairs of digitiform projections in the aedeagal complex; the inner projection about twice longer than lateral projection ( Figs. 22G, 22E ). Aedeagus ending at apex of projections in the aedeagal complex ( Fig. 22G ). Ejaculatory apodeme short, 0.3 times the length of gonostylus. Epandrium longer than wide. Cercus piriform ( Fig. 22H ) with two short apical bristles ( Fig. 22F ). Hypoproct with apical micropilosity ( Fig. 22H ).

Female. Unknown.

Material examined. Brazil, Bahia, Ituberá municipaliy, 15.VII.2002, holotype ♂, I. Castro leg. ( MZFS); 12 paratypes: 6 ♂, same locality as holotype, 12.VI.2002, F. Bravo leg. ( MZFS); 6 ♂, same locality, 01.VII.2003, F. Bravo leg. ( MZFS).

Etymology. From Latim, complicatus, refers to the shape of projections in the aedeagal complex. Distribution. Brazil—Bahia.
