Scutellum with well-developed apical setae, basal setae absent. Metepimeral bridge present: posteroventral area of thorax behind and above hind coxae between metepimera sclerotized.

Legs. Coxa of foreleg long and simple, with several setae apically. Femur of foreleg with 3 anteroventral setae and 3-4 posteroventral setae. Fore tibia with two rows of short setae ventrally. Coxa of midleg bare in upper half. Femur of midleg curved at middle. Tibia of midleg with 1 v in apical third, a row of short anterior setae and with apical d, av and pv. Femur of hindleg with a row of short setae dorsally. Tibia of hindleg without osmeterium or osmeterium-like area, with 3-4 short setae dorsally.

Wing longer than abdomen, with well-developed anal lobe. Cells bm and br separate. Alula with microtrichia. Margin of upper calypter without hairs. Margin of lower calypter with hairs.
