Female macroptera: Body pale, slightly shaded on the pronotum, lateral sides of the meso and metanota; abdominal tergites III–VII with median brown area not extending laterally to setal pair S2; tergites III–VIII and sternites III–VII with medially dark antecostal ridges; fore wings shaded, apex pale; legs pale, but slightly shaded on outer surfaces of femur and tibiae. Head with transverse striations; ocellar setae III situated close to fore ocellus on the tangent between fore and hind ocelli; four pairs of postocular setae, setae I and II equal to or slightly longer than ocellar setae III, setae III minute, setae IV arising laterally and shorter than I and II. Antennae 8 segmented, segments III and IV with forked sense cone; segment II with middorsal seta, without campaniform sensilla. Pronotum with closely spaced striae; posteromarginal setae four pairs, S2 setae 1.3 times as long as S1. Metascutum with transverse striations anteromedially, longitudinal reticulations medially and transverse reticulations posteromedially; median pair of setae near or at the anterior margin, without campaniform sensilla. Fore wing first vein with 8–11 basal setae irregularly spaced and 3–7 setae on distal half, second vein with 2–3 setae; posteromarginal fringe cilia straight. Abdominal tergites with S1 setae close to each other, longer than their intervals; tergites II–VII with posteromarginal microtrichia lateral to S2 setae, with 3–5 discal setae on lateral microtrichial fields of III–VII; tergite VIII with microtrichia anteromedially, having complete posteromarginal comb; tergite IX with microtrichia posteromedially but without campaniform sensilla; tergite X with microtrichia posteromedially; sternites II–VII fully covered by rows of microtrichia, posterior margin with complete comb of microtrichia; sternite VII with S1 setae slightly in front of posterior margin; with paired trivial flange projection.

Male macroptera: Similar in colour and sculpture to female except body smaller; fore wing first vein with 6–8 basal setae, 3–4 setae on distal half; second vein with 0–1 seta; tergite IX with a pair of dark, incurved drepanae; with pale antecostal ridges and without pore plate on abdominal sternites.
