Material examined. Types: holotype ♂: CHINA: Yunnan, Yongshan County, Huanghua Town, 28°00'N 103°51'E, 1500 m, 30.X.2010, reared from Arboridia sinensis feeding on Zanthoxylum bungeanum, Wei Dong leg. (SCAU). Paratypes: same locality label as holotype, 5♂ and 2♀♀ (SCAU); same locality label as holotype, 1♂ and 1♀ (MOLC); same locality label as holotype, 8.X.2010, 4♀♀ and 4♂ (SCAU).

Hosts: Cicadellidae Typhlocybinae (Xu et al., 2011c): in China, Yunnan: Arboridia sinensis Guglielmino, Xu, Bückle & Dong 2012 (Plate 6D) feeding on Zanthoxylum bungeanum Maximowicz (Rutaceae) (Chinese pricklyash; Sichuan pepper tree). Xu et al. (2011c) attributed erroneously the host to Alebroides genus.

Distribution. China (Yunnan).
