DistributionRead full entry
Range DescriptionThe species has a patchy distribution in northern Lao PDR, Viet Nam and China (southern Yunnan, Guangxi and Hainan island) (Smith et al. 2008). Wang (2003) recognized two subspecies in China: H. d. delacouri, Thomas, 1927, occurring in mainland China; H. d. marmosa, Allen, 1927, occurring on Hainan island.
It is probably now patchily distributed because of habitat loss.
