Diagnosis: nine black ocellar setae; face and front covered with yellow to brown pruinescence; anepisternum with a tuff of black and white setae on dorsal margin; 14 yellow pronotal macrosetae; tergite I with black macrosetae and brown undulated setae on apex; gonocoxite with rectangular posteroventral projection ( Figs. 49, 53 View Figures 48–53 ); gonostylus bilobed apically ( Fig.51 View Figures 48–53 ); proximal margin of hypandrium rounded, distal margin with long median projection ( Fig. 50 View Figures 48–53 ); epandrium in lateral view, with slight concavity ( Fig. 53 View Figures 48–53 ); ejaculatory apodeme without spines ( Fig.52 View Figures 48–53 ); aedeagal prongs with two adjacent subapical dilations, the more apical one less inflated ( Figs. 48, 52 View Figures 48–53 ).

Description. Male. Head ( Figs. 4 View Figures 1–5 , 9 View Figures 6–10 ). Nine ocellar setae, black and undulated at apex; eight to twelve brown setae on lateral surface; six to seven black and brown postocular macrosetae; four to five black and yellow orbital macrosetae; dorsal region of mystax with seven black macrosetae, median and ventral region with 14 brownish macrosetae; three to four black subvibrissal macrosetae; inferior occipital setae white and branched; six occipital brownish macrosetae; proboscial setae white and branched at base, whiteyellowish and undulated at apex; palpus with black setae. Face and front covered with yellow to brown pruinescence; face wide at antennal level, the same width as eye in lateral view; front with transversal spot; gena covered with brown pruinescence. Scape 2.0× the length of pedicel; scape with ventral yellow setae and some black setae on dorsal surface; postpedicel 1.5× the lengths of scape and pedicel together, base dark brown, stylus dark brown to black. Gena dark brown, lateral width of gena 0.17× the lateral length of compound eye.

Thorax. 14 yellow pronotal macrosetae; postpronotal lobe covered with black and white seta; two black notopleural macrosetae; two black supraalar macrosetae; one to three black postalar macrosetae; 12–14 apical scutellar macrosetae; discal setae dark brown, undulated at apex; two black acrostichal setae; four dorsocentral macrosetae. Postalar wall with row of yellow setae. Anepisternum with tuff of black and white setae on dorsal margin; basalar sclerite with black setae. Katepisternum with many brown setae. Katepimeron glabrous.

Wing. ( Fig. 13 View Figures 11–15 ); membrane yellowish. Halters brown.

Abdomen. Tergite I with black macrosetae and brown setae undulated at apex, posterior margin fringed with macrosetae and setae, the remaining surface covered with black and white setae. Lateral margins of tergite II with white setae, dorsal margin covered with short white setae. Lateral margins of tergite III with black setae; dorsal surface covered with short black setae. Tergites IV and V black. Tergite VI white, with median triangular spot. Tergite VII black, with white lateral stripe.

Terminalia ( Figs. 48–53 View Figures 48–53 ). Proximal margin of hypandrium rounded, distal margin with long median projection ( Fig.50 View Figures 48–53 ). Gonocoxite with rectangular posteroventral projection ( Figs. 49, 53 View Figures 48–53 ). Gonostylus ending with two short lobes ( Fig. 51 View Figures 48–53 ). Aedeagal prongs with two terminal dilations each, proximal dilations wider than apical ( Figs. 48, 52 View Figures 48–53 ). Ejaculatory apodeme without spines ( Fig. 52 View Figures 48–53 ).
