Diagnosis. Apex of Sc unsclerotized; M2 with base unsclerotized; hypandrium involving the aedeagus, with a subspherical dorsal projection; arm of gonocoxite elongated coated laterally by bristles and apically by two setae; one pair of projections in the aedeagal complex; involving the aedeagus, curve-shaped; ejaculatory apodeme short, 1.25 times the length of gonostylus; cercus with apical rod-like bristles.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; scape and pedicel subspherical; flagellomeres pyriform and eccentric (Fig. 29A); ascoids 1.3 times as long as the length of flagellomere; 13th flagellomere subcylindrical with terminal apiculus separated by a suture (Fig. 29G). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.7:0.8 (Fig. 29B). Wing. apex of Sc unsclerotized; sc-r unsclerotized; R4+5 with base unsclerotized; M2 with base unsclerotized, r-m unsclerotized and m-cu absent (Fig. 29D). Male terminalia: Hypandrium and gonocoxites fused, hypandrium involving the aedeagus, with a dorsal subspherical projection (Figs. 29F, 29H). Gonocoxites with elongate arm coated laterally with bristles and apically with two setae. Gonostylus unsclerotized, subtriangular. Presence of one pair of projections in the aedeagal complex; involving the aedeagus, curved-shaped. Aedeagus with expanded and rounded apex (Fig. 29F). Ejaculatory apodeme short, 1.25 times the length of gonostylus. Epandrium subcircular; elongated cercus, digitiform, with rod-like bristles in the ventral surface of the apex, about five (Fig. 29E, 29I). Hypoproct tapering apically with apical micropilosity and expanded basally. Epiproct triangular with pointed apex (Figs. 29H, 29I).

Female. Unknown.

Etymology. The epiteht is allusive to the different shaped of hypandrium that involving the aedeagus, with a subspherical projection, characteristic totally different from other species of the genus.

Distribution. Brazil—Amazonas, Pará.
