Material examined. 1 female ( HIST), CHINA: Shaanxi Province, HanZhong , Yang County, Guandi town , Χiaoxigou Village , 1270 m, N 33°48.87' E 107°40.56', 2017. V.3, Haoyu Liu ; 1 female ( HIST), Huayang town, Gumuping Village , 1455 m, N 33°59.34' E 107°47.60', 2017. V.12, Haoyu Liu ; 2 males and 1 female ( HIST), CHINA: Shaanxi Province, HanZhong, Foping County, Sanguanmiao station , 2011. IV.8, Weihai Li.

Female ( Figs. 9a–9b ). Sternum 7 with large sclerotiZed fan-shaped pregenital plate, plate corners forming nipple-like hump and posterior margin evenly concaved, covering at least 2⁄3 width of sternum 7. Sternum 8 with subquadrate membranous subgenital plate, consisting of a pair of posterolateral sclerites mostly covered by the main membrane; a pair of sclerotiZed lateral lobes nipple-like, extended from the mesolateral margin of subgenital plate. Sternum 9 mostly sclerotiZed, with a trapeZoidal anterior indentation, nearly as wide as the subgenital plate.

Distribution. China (Shaanxi, Sichuan).

Remarks. This species was recently redescribed based on the holotype and 1 male paratype but no associated female were available (Yang et al. 2015). The fresh material from Yang County includes two females, but from the Foping Nature Reserve, both sexes were associated. This is the same site for the recently described larvae of Paraleuctra tianmushana Li & Yang, 2010 ( Li et al. 2016).
