Female. (Figs. 33–36) Frons 0.28–0.29 of head width; frontal vitta paralleled on inner and outer margins, wider than fronto-orbital plate; ocellar seta weak; frontal setae reclinate, upper ones stronger; 1 anterior vertical seta, 2 proclinate outer orbital setae. Abdomen with appressed hairs, terminalia without spine–covered lobes.
Male. (Figs. 25–28) Eyes bare, facets larger on upper half of eye and smaller on lower half. Frons narrower than palpus width, frontal setae only at anterior half of frons, face bare, without carina, not visible in lateral view. Parafacial bare, less than antenna width, genal height 1/6–1/7 of eyes height. Hairs on posteroventral half of head predominantly black. Antenna black in male and postpedicel dark and pedicel reddish brown in female; arista thickened at basal 1/3, pubescent, longest aristal hairs more than aristal diameter. Palpi reddish brown to dark in male and reddish yellow in female. Prementum about two times as long as its diameter. Body dark on thorax and abdomen. Scutum with 1–2 presutural and 2 postsutural acrostichal setae, 2 presutural and 4 postsutural dorsocentral setae, 2 postsutural intra-alar setae. Katepisternum with two setae. Anepimeral seta not differentiated from the usual anepimeral hairs. Scutellum with 3 pairs of marginal setae, strong crossed apical setae, subapical scutellar setae weaker than apical scutellar setae. Wings with dark tegula and basicosta. Calypters dark brown. Costal sectors 2nd less than 1/3 of 3rd length. Vein R 4+5 with a few setae at base, wing cell r 4+5 open, last part of vein Cu shorter than crossvein dm-cu. Legs black. Fore tibia with 1 posterior seta, preapical anterodorsal seta at least as long as preapical dorsal seta, mid tibia with 1 anterodorsal and 1 weak ventral seta, hind tibia with 2 preapical dorsal setae.Abdominal syntergite 1+2 without median marginal seta, its middorsal depression nearly extending back to hind margin, tergites 3 with 2 median marginal setaem and tergite 4 with a row of marginal setae, tergites 3 and 4 each without median discal seta. tergite 4 with 1–2 lateral discal setae, tergite 5 with a row of marginal setae and a row of discal setae, 1.3 times as long as tergite 4.
