This species occurs in central and southeast China (Jiangsu, Jiangxi, Guangdong, Hong Kong, Guangxi, Fujian, Hainan, Hunan, Zhejiang, Sichuan, Guizhou, and Yunnan provinces), extending to Thailand, Myanmar and Viet Nam (Smith et al. 2008). It can be expected in northern Lao PDR, but this has not yet been confirmed. In Myanmar it is found between 50-1,000 m asl in elevation (P. Bates pers. comm.).
