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); gonostylus bilobed apically (Fig.51); proximal margin of hypandrium rounded, distal margin with long median projection (Fig. 50); epandrium in lateral view, with slight concavity (Fig. 53); ejaculatory apodeme without spines (Fig.52); aedeagal prongs with two adjacent subapical dilations, the more apical one less inflated (Figs. 48, 52).  
Description. Male. Head (Figs. 4, 9). 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.

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); 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.
