Systolederus guangxiensis Zheng, 1998 : in Liang & Zheng, 1998: 100 [description] (holotype — ♂, China: Guangxi prov., Shangsi County, Hongqishan, in IZSNU, examined); Zheng, 1998: 169; Jiang & Zheng, 1998: 302; Zheng & Jiang, 2003: 80; Jiang & Liang, 2004: 203; Zheng, 2004: 74; Zheng, 2005b: 117; Deng, Zheng & Wei. 2007: 113; Zheng, 2013: 3; Deng, 2016: 106; Deng, Lu, Zhao & Wu, 2019: 496 .

Xistra longzhouensis Zheng & Jiang, 1998 : in Jiang & Zheng, 1998:303 [description] (holotype — ♂, China: Guangxi prov., Longzhou County, Nonggang,in IZSNU, examined); Zheng, 2004: 74; Zheng, 2005b: 128; Deng, Zheng & Wei, 2007a: 122; Zheng, 2009: 298; Li, Deng, Zheng, Lin & Lu, 2014: 213; Deng, Zheng, Li, Lin, Wei, Yuan & Lin, 2015: 158; Deng, 2016: 118; syn. nov.

Type material examined. Systolederus guangxiensis : holotype, ♂, China: Guangxi prov., Shangsi County, Hongqishan , 09 July 1991, in IZSNU ( Fig. 6e ) ; paratypes, 3 ♀, the same data as holotype, IZSNU . Xistra longzhouensis : holotype, ♂, China: Guangxi prov., Longzhou County, Nonggang , 27 May 1994, in IZSNU ( Fig. 6f ) ; paratypes, 1 ♂ 3♀, the same data as holotype, IZSNU .

Notes. Systolederus guangxiensis 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 guangxiensis and Xistra longzhouensis , and found that structures and coloration of the body are the same in both taxa. Therefore, Xistra longzhouensis is here considered a synonym of of Systolederus guangxiensis [= Xistra guangxiensis ( Zheng, 1998) , comb. nov.]
