It is endemic to the Yunwu Mountains in Guangdong, southern China,[1][3] and known from its type locality near Nanchong village, Fuhe, Luoding City, and from the Yunkai National National Nature Reserve.

Males have a bluish-white caudal stripe on the posterior half of the tail.

[2] Paramesotriton yunwuensis occurs in cold, clear, slow-moving streams and pools surrounded by evergreen broad-leaved forest at elevations of 300–1,200 m (980–3,940 ft) above sea level.

However, the total population is still small (<2,500 adults), and this number is believed to be declining.

Collection for the pet trade as well as habitat degradation and pollution caused by hydropower and tourism are threats.
