A key to Chinese species of Euparatettix is given. Type specimens are kept in the Institute of Zoology,Shaanxi Normal University. Euparatettix zayuensis sp. nov. （Figs 1-3） This new species is allied to Euparatettix brachyptera Zheng et Mao,2002 and Euparatettix rongshuiensis Zheng,2005. It differs from species the former in：1） hind process reaching knee of hind femur; 2） top of hind process sharp; 3） hind tibia brown. It differs from the latter species in：1） anterior margin of vertex slightly protruding before eyes; 2） vertex and frontal ridge forming an obtuse angular in profile; 3） lower outer side of hind femur not black. ♀ length of body 10.0-10.2 mm,length of pronotum 8.0-8.4 mm,length of hind femur 5.5-6.0 mm. Holotype ♀,Xizang,Zayu （97°5′N,28°8′E）,5 July 2005,collected by SHI Ai-Min. Paratype 1♀,same data as holotype. Etymology. The specific name is derived from the type locality ＂Zayu＂.
