Trichomyia crinita Araújo & Bravo sp. nov.

( Figs. 24A–G )

Diagnosis. Gonocoxite with two pairs of elongated expansions; arm of gonocoxite with an expansion spur-shaped with sclerotized apex and with elongated bristles; one pair of filiform projections in the aedeagal complex; ejaculatory apodeme short, 1.2 times the length of gonostylus; cercus with two rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape and pedicel subspherical; flagellomeres pyriform and eccentric ( Fig. 24A ); ascoids 1.4 times longer than the flagellomere; 13th flagellomere subcylindrical with terminal apiculus separated by suture ( Fig. 24B ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.5:0.7 ( Fig. 24E ). Wing. R4+5 with base unsclerotized; r-m unsclerotized and m-cu absent ( Fig. 24D ). Male terminalia: Hypandrium and gonocoxites fused with two pairs of elongated expansions, one medial plate-like and other basal and tubular. Arm of gonocoxite with an expansion spur-shaped with sclerotized apex and with elongated bristles. ( Figs. 24C, 24G ). Gonostylus digitiform, slightly sclerotized, articulated ventrally to gonocoxite, bare, curved, with rounded tip. Presence of one pair of filiform projections in the aedeagal complex. Aedeagus with pointed apex ( Fig. 24G ). Ejaculatory apodeme short, 1.2 times the length of gonostylus. Epandrium subcircular. Cercus with an apical expansion with two rod-like bristles. Hypoproct with apical micropilosity ( Fig. 24F ).

Female. Unknown.

Material examined. Brazil, Amazonas, Manacapuru, 27.XI.2001, holotype ♂, without name of collector ( MZFS).

Etymology. From Latim, crinita = comet, refers to the shape of arm of gonocoxite.
