Trichomyia hispida Araújo & Bravo sp. nov.

( Figs. 28A–H )

Diagnosis. R4+5 complete at base; r-m present; arm of gonocoxite sinuous, apically with many short and thick bristles; two pairs of projections in the aedeagal complex, the subtriangular dorsal with sharp apex; the ventral, with sharp apex, longer than the dorsal projection, jointed apically by a ventral membrane; ejaculatory apodeme twice the length of gonostylus; cercus with a projection with two apical bristles.

Description. Male. Head subcircular in frontal view. Antenna: scape subcylindrical about as long as the subspherical pedicel; flagellum with 13 flagellomeres, 1st to 12th pyriforms and eccentric ( Fig. 28A ); 13th flagellomere subcylindrical with terminal apiculus separated by suture ( Fig. 28C ); pair of digitiform ascoids present in all flagellomeres; basal ascoids 1.3–1.4 times the length of flagellomere ( Fig. 28A ); apical ascoids 1.2 times the length of flagellomere ( Fig. 28C ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.8 ( Fig. 28B ). Wing. R4+5 complete at base; r-m present; m-cu absent ( Fig. 28D ). Male terminalia: Hypandrium fused with gonocoxites narrow. Gonocoxites with posterior sinuous arm, apically with many short and thick bristles. Gonostylus articulated ventrally to gonocoxite, digitiform, bare. Two pairs of projections in the aedeagal complex, the first dorsal pair, subtriangular, with sharp apex and directed to the midline; the second pair of projections, ventral, complex, with sharp apex, longer than the dorsal projections, jointed apically by a ventral membrane. Aedeagus short ( Fig. 28H ). Ejaculatory apodeme twice the length of gonostylus. Epandrium subrectangular ( Figs. 28E, 28G ). Cercus bottle-shaped in lateral view with two apical bristles ( Fig. 28F ). Hypoproct with apical micropilosity ( Fig. 28E ).

Female. Unknown.

Material examined. Brazil, Bahia, Coração de Maria municipality, 28.I.2004, holotype ♂, F. Bravo leg. ( MZFS); 3 paratypes: 1 ♂, same locality, date and collector than holotype ( MZFS); 2 ♂, Brazil, Bahia, Cachoeira municipality, Fazenda Villa Rial, 28.VII.2004, F. Bravo leg. ( MZFS).

Etymology. From Latim, hispidus, meaning bristly referring to the presence of apical bristles in the cercus.

Distribution. Brazil—Bahia.
