Xistra emeiensis ( Zheng, 1998 ) , comb. nov. Systolederus emeiensis Zheng, 1998 : in Liang & Zheng, 1998: 101 [description] ( holotype — ♀ , China : Sichuan prov. , Emeishan County, Hongchunping, in IZSNU, examined); Zheng, 2005b: 118 ; Cao & Zheng, 2011: 738 ; Zheng, 2013: 3 ; Deng, 2016: 106 ; Deng, Lu, Zhao & Wu, 2019: 496 . Xistra yaanensis Zheng, 2009: 298 [description] ( holotype — ♂ , China : Sichuan prov. , Yaan City, in IZSNU, examined); Li, Deng, Zheng, Lin & Lu, 2014: 214 ; Deng, 2016: 119 ; syn. nov. Type material examined. Systolederus emeiensis : holotype , ♀ , China : Sichuan prov. , Emeishan County , Hongchunping , 01 September 1980 , in IZSNU ( Fig. 6c ) . Xistra yaanensis : holotype , ♂ , China : Sichuan prov. , Yaan City , 28 July 2004 , in IZSNU ( Fig. 6d ) ; paratypes , 1 ♂ , the same data as holotype, IZSNU . Notes. Systolederus emeiensis is not a Systolederus species because eyes not draw to each other in front giving the triangular shape to vertex; vertex well depressed, lateral margins of vertex turned backward and elevated up to upper margin of eyes. It belongs to Xistra Bolívar, 1817 . We have examined the type specimens of Systolederus emeiensis and Xistra yaanensis , and found that structures and coloration of the body are the same in both taxa. Therefore, Xistra yaanensis is here considered a synonym of of Systolederus emeiensis [= Xistra emeiensis ( Zheng, 1998 ) , comb. nov . ]
