Formosatettix guangxiensis Zheng & Jiang, 1998 [description] (holotype —♁, China: Guangxi prov., Shangsi County, Hongqi, in IZSNU, examined); Jiang & Zheng, 1998: 344; Zheng, 2005: 352; Deng, Zheng & Wei, 2007b: 317; Deng, 2016: 272; Wei, Deng & Lu, 2019: 1003; syn. nov.

Type material examined. Holotype Pseudepitettix guangxiensis , ♁, China: Guangxi prov., Shangsi County, Hongqi , 9. July 1991, in IZSNU . Holotype Formosatettix guangxiensis , ♁, China: Guangxi prov., Shangsi County, Hongqi , 9. July 1991, in IZSNU . Other material examined. 11♁ 10♀, China: Guangxi prov., Shangsi County, Wangle , 23 July 2013, EMHU ; 7♁ 15♀, China: Guangxi prov., Fangchen County, Fulong , 20 July 2012, EMHU .

Notes. We examined the type specimens of Pseudepitettix guangxiensis and Formosatettix guangxiensis , and found that the structures, type locality and coloration of the body are the same in both taxa. Therefore, a new synomimy is here established.

The comparison of the holotype of Pseudepitettix guangxiensis and Formosatettix guangxiensis and their additional specimens show that these taxa are conspecific and characterized by the vertex is distinctly surpassing anterior margin of eyes as an evenly broad, rounded process; the vertex is much wider than one of the eyes; the apex of the hind pronotal process is concave.
