PARATYPES: 16 ♁♁, same data as holotype; 16 ♁♁, same data as holotype except Juan Han leg.; 2♁♁, same data as holotype except 3.ix.2010; 9♁♁, Jinghong, Yexianggu, 30.viii.2010, light trap, Meng Zhang leg. (all NWAU).

Description. Ground color ( Figs 12 E–H) dirty tawny, eyes black, vertex dirty pale-yellow, with blurry orange markings and small black patch in middle of transition from crown to face; frontoclypeal area dark with edges lighter, anteclypeus brown basomedially, lorum and gena pale. Pronotum with large black medial patch on fore margin. Scutum and scutellum off-white, black at tip. Forewing brown, with several lighter areas.

Abdominal apodemes 2S ( Fig. 2E ) extremely small, apodemes 3T ( Figs 2C, D ) variable in size among individuals.

Male terminalia.Anal tube ( Fig. 2F ) weakly sclerotized basally, with short appendage ( Fig. 2G ), bent in right angle, apex blunt. Pygofer side ( Fig. 2F ) nearly rectangular, hind margin truncate; dorsal appendage ( Figs 2F, G ) short, slightly curved ventrad. Subgenital plate ( Figs 2I, J ) with membranous dorsal side wider than sclerotized ventral side in apical part, with 2–3 macrosetae. Style ( Figs 2K, L ) with apex lance-shaped in lateral view, curved ventrad. Connective ( Fig. 2M ) broad, central lobe slim and long. Aedeagal shaft ( Figs 2N, O ) with lateral surfaces well sclerotized, bifurcated both basally and apically in ventral view, two sides only fused at the connection with preatrium, with membranous inner side and apical part; dorsal apodeme wide in ventral view; preatrium about twice longer than shaft; gonopore not delimited.
