Trichomyia cerdosa Araújo & Bravo sp. nov.

( Figs. 20A–H )

Diagnosis. Arm of gonocoxites S-shaped in lateral view with a tuft of elongated apical bristles; one pair of elongated projections in the aedeagal complex with lanceolate apex; ejaculatory apodeme short, 0.3 times the length of gonostylus; cercus with apical bristles, spatulate.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical as long as the subspherical pedicel; basal flagellomeres pyriform, asymmetric ( Fig. 20A ); 13th flagellomere subcylindrical with terminal apiculus separated by suture ( Fig. 20H ); ascoids 1.6 times the length of flagellomere ( Fig. 20C ). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.5 ( Fig. 20B ). Wing. R4+5 incomplete at base; r-m and m-cu absent ( Fig. 20D ). Male terminalia: Hypandrium fused with gonocoxites. Arm of gonocoxites S-shaped in lateral view with a tuft of elongate apical bristles ( Fig. 20F ). Gonostylus articulated ventrally to gonocoxite, almost as long as the lobe of the gonocoxite in lateral view, bare ( Figs. 20F, 20G ). One pair of elongate projections in the aedeagal complex, with lanciform apex. Aedeagus ending before the apex of projections in the aedeagal complex ( Fig. 20F ). Ejaculatory apodeme in lateral view short, 0.3 times the length of lobe of gonostylus. Epandrium pilose, longer than wide. Cercus pilose, piriform in lateral view with four apical bristles, spatulate ( Fig. 20G ). Hypoproct with apical micropilosity ( Fig. 20E ).

Female. Unknown.

Material examined. Brazil, Bahia, Ituberá municipality, 12.VI.2002, holotype ♂, F. Bravo ( MZFS); 2 paratypes: 1 ♂, same locality and collector as holotype, 01.VII.2003 ( MZFS); 1 ♂, Brazil, Bahia, Cachoeira, Fazenda Villa Rial, F. Bravo leg. 24.V.2004 ( MZFS).

Etymology. The epithet cerdosa is allusive to the large quantity of bristles on the arm of gonocoxite.

Distribution. Brazil—Bahia.
