This species is here newly recorded from India, and the brachypterous form described for the first time, based on the specimens indicated below. It was described from Nepal on three macropterous females taken from evergreen tree, bamboo and dead branches, and the male was described from China on specimens collected from flowers of Asteraceae (Hu & Feng 2013).
Female (brachyptera). Body dark black including legs and antennae (Fig.1). Head longer than wide, slightly produced in front and slightly constricted just behind eyes, with elongate reticulations (Fig. 10); with three pairs of ocellar setae, ocellar I present, ocellar III behind the fore ocellus, longer than ocellar I and II; eyes swollen without pigmented facets; postocular setae not in one row, poII behind poI; mouthcone rounded at apex. Antennae 8- segmented; segments III and IV each with forked sense cones. Pronotum wider than long with few transverse lines, with few discal setae, 2 pairs of posteromarginal setae inner to long major posteroangulars; median setae at posterior margin of pronotum longer than submedian setae (Fig.10). Mesonotum with reticulate sculpture; median pair of setae ahead of posterior margin; anteromedian campaniform sensilla present. Metanotum polygonally reticulate; median pair of setae far behind anterior margin, gap between median pair of setae and median and submedian variable in 3 specimens (Figs 11–13); campaniform sensilla present. Basantra weakly chitinised; spinula present on mesosternum, absent on metasternum. Fore wing with 5–7 costal setae; upper vein with 4+0 to 4+2 setae, lower vein without setae; clavus with 4+1 to 5+1 setae. Abdominal tergite I completely polygonally reticulate; II–VII completely polygonally reticulate except along posterior margin; VIII reticulate at anterior margin only; campaniform sensilla on abdominal tergites slightly ahead of posterior margin; tergite VIII with complete, fine comb of microtrichia at posterior margin; tergite IX smooth with 2 pairs of campaniform sensilla; median setae long, extending to apex of X; tergite X elongate, with margins almost parallel, with elongate reticulation, with complete ventral longitudinal split. Abdominal sternite II with 2 pairs of posteromarginal setae, III–VII with 3 pairs; on VIII median setae (S1) slightly ahead of posterior margin; sternites and laterotergites without discal setae.
Second Instar Larva. Body pale yellow with light brown antenna and legs (Fig. 2).
Material studied: INDIA, Himachal Pradesh, Chamba District: Dalhousie, (32º32'02.2"N 76º01'39"E, 2444 m) 3 brachypterous females and 25 larvae from yellow flowers & leaves of unidentified plant, 12.x.2013, Vikas & Kaomud (Reg. 5859/H17 to 5864/H17).
