Trichomyia imarui Araújo & Bravo sp. nov.

(Figs. 33–39)

Diagnosis. Gonocoxite with posterior arm short, with a row of nine rod-like setae. Two pairs of U-shaped parameres present; dorsal paramere longer and wider than ventral one.

Description. Male. Head subcircular. Palpus formula 1.0:0.6:0.7 (Fig. 35). Antenna incomplete in the specimens studied; scape and pedicel subspherical; basal flagellomeres pyriform, eccentric; ascoids 0.9 times as long as flagellomere (Fig. 33). Wing (Fig. 34): Apex of Sc and sc-r unsclerotized; R5 incomplete, M2 with base unsclerotized, r-m and m-cu absent. Elongate bristles of tergum 7 with straight apices (Fig. 36). Male terminalia: Epandrium wider than long (Fig. 39); cercus pilose subtriangular (Fig. 37, 39). Hypandrium and gonocoxites fused (Fig. 38). Gonocoxite with posterior arm short, with row of nine rod-like setae (Fig. 38). Gonostylus approximately the same length as gonocoxite arm (Fig. 38). Hypropoct triangular, with apical micropilosity (Fig. 39). Two pairs of U-shaped parameres present; dorsal paramere longer and wider than ventral one (Fig. 39). Aedeagus simple, with one opening (Fig. 39). Aedeagal apodeme long, four times the length of gonostylus (Fig. 38).

Material examined. Holotype 3, BRAZIL, Pará, N.[Novo] Repartimento, Vic. [Vicente] Bandeirante, Sítio Pedro Roqueta, 19. VIII.1998, without name of collector ( MZFS); 3 paratypes: 2 3, same locality and data as holotype ( MZFS), 1 3, same locality as holotype, 15.VIII.1998, without name of collector ( INPA).

Distribution. Known from Novo Repartimento in Pará, Brazil.

Etymology. imauri means mosquito in the indigenous Brazilian Tupi-Guarani linguistic family.

Comments. The rows of rod-like setae in T. imarui sp. nov., T. bou , T. cauga , and T. mishi are located on the external margin of the posterior arm of the gonocoxite, much like a crest; in the other species, the rod-setae are smaller and internal ( T. pedrabranquensis , T. sertaneja , T. atlantica ), or apical ( T. amazonensis ), or thin ( T. botosaneanui , T. dolichakis ), or absent ( T. jezeki ).
