Trichomyia cetrae Araújo & Bravo sp. nov.

( Figs. 4A–G )

Diagnosis. Medial posterior expansion on gonocoxite, apically bifurcate; gonostylus bifurcate, sclerotized, articulated ventrally at gonocoxite; aedeagal complex with two pairs of projections, one dorsal subtriangular and one ventral wider than dorsal projection; ejaculatory apodeme twice the length of gonostylus.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape as long as the subspherical pedicel; ( Fig. 4A ); flagellomeres pyriform and eccentric; ascoids twice the length of flagellomere ( Fig. 4B ). Palpus formula 1.0:0.7:0.9 ( Fig. 4C ). Wing. R4+5 incomplete at base; r-m and m-cu absent ( Fig. 4D ). Male terminalia: Hypandrium fused with gonocoxites, with medial posterior expansion, apically bifurcate ( Fig. 4E ). Arm of gonocoxites L inverted shaped in lateral view ( Fig. 4G ) and with elongated bristles along the medial margin. Gonostylus bifurcate, sclerotized, articulated dorsally at gonocoxite ( Fig. 4E ). Two pairs of projections in the aedeagal complex dorsal pair subtriangular, ventral pair wider than dorsal projections in the aedeagal complex ( Fig. 4G ). Aedeagus truncated in the apex ( Fig. 4E ). Ejaculatory apodeme twice the length of gonostylus ( Figs. 4E, 4G ). Epandrium pilose, apically wider than basally ( Fig. 4F ). Cercus pilose ( Figs. 4E ), rhomboid in lateral view ( Fig. 4G ). Hypoproct with apical micropilosity ( Fig. 4F ).

Female. Unknown.

Material examined. Brazil, Bahia, Cachoeira municipality, Fazenda Villa Rial, 24.V.2004, holotype ♂, F. Bravo leg. (MZUEFS).
