Formosatettix xiai Zheng, Shi and Yin, 2015 , p. 146 ( holotype – 3, paratypes – 432 ♀ , China : Zhejiang , Tianmushan ; in Hebei University , China ; not examined; syn. nov.). Notes We examined the holotype of F. tianmushanensis and compared with type specimen photographs and the description of F. xiai ( Zheng et al. 2015 ) and found that morphology and distribution are completely identical in both taxa. Thus, we synonymise F. xiai with F. tianmushanensis .
