Range DescriptionC. yunnanensis has been reported only from Kunming Fu and Tongchuan Fu [=Dongchuan fide Iverson, 1992, but refers to Zhongping (=Huize) City fide Blanck et al. 2006] in Yunnan, China, at the time of its 1906 description (Iverson 1992, Parham et al. 2004), and a single animal from Xi Shan (Western Mountains) near Kunming collected in 1940 (Zhang and Cheng 1946). It is likely that these animals were purchased in markets and may have been transported by humans, possibly for substantial distances (Blanck 2005). Three more specimens in the Institute of Zoology in Beijing (Parham et al. 2004, Blanck 2005) have no reported locality data or collection date. The origin of three recent specimens discovered since 2004 and now held in captivity has not been recorded (Zhou and Zhao 2004, Zhou 2005, He et al. 2007), and the precise geographic origin of C. yunnanensis remains subject of speculation, with northwestern Yunnan and adjacent Sichuan, northeastern Yunnan close to the Myanmar border, southern Yunnan, and northern Laos having been suggested (Blanck 2005, Blanck et al. 2006, Zhou et al. 2008, Yang and Rao, 2008).
