D27AC06F78ED513FA4ED0B12B96FA665.taxon	distribution	Distribution and habits. Currently, Takydromus yunkaiensis sp. nov. is known only from its type locality of Dawuling Forestry Station, adjacent Xianrendong Scenic Area located in the southern Yunkai Mountains in western Guangdong Province, China (Fig. 1). The diurnal species was found to be very active in daytime and rapidly escapes when disturbed, and is usually observed resting on fern leaves at night. The surrounding environment was covered by well-preserved montane evergreen broad-leaved forest or mixed forest (Fig. 5) at altitudes of 900 - 1600 m.	en	Wang, Jian, Lyu, Zhi-Tong, Yang, Chen-Yu, Li, Yu-Long, Wang, Ying-Yong (2019): A new species of the genus Takydromus (Squamata, Lacertidae) from southwestern Guangdong, China.
