Abstract

Two new pygmy grasshopper species are described from PR China and are assigned to Formosatettix Tinkham, 1937, a large Asian tetrigin genus composed of species with reduced tegmina and hind wings: F. leigongshanensis Zha & Ding, sp. nov. from Guizhou and F. wulongensis Zha & Ding, sp. nov. from Chongqing. We provide descriptions of morphology and habit, supplemented with photographs. Flying organs of the genus Formosatettix are discussed and the genus is compared with other Asian genera with reduced flying organs, such as Formosatettixoides Zheng, 1994 and Alulatettix Liang, 1993 in Tetriginae, Deltonotus Hancock, 1904, Epitettix Hancock, 1907 and Pseudepitettix Zheng, 1995 in Cladonotinae, and Macromotettixoides Zheng, Wei & Jiang, 2005 and Pseudomacromotettix Zheng, Li & Lin, 2012 in Metrodorinae.
