Material examined

Holotype: „, P. R. China, Guangxi: Banli, Chongzuo (22 ° 15 9 N, 107 ° 30 9 E), 130 m, coll. 20 August 2004 (G.-F. Jiang) . Paratypes: 4 „„, same data as holotype.

This new species is allied to Coptotettix longjiangensis Zheng and Wei (2000) , but differs in: (1) upper margin of pronotum nearly straight in profile; (2) part between humeral angles with a pair of abbreviated carinae; (3) hind process of pronotum slightly reaching beyond the top of hind femur; and (4) wing not reaching the apex of hind process.
