In order to offset the damage done to their interests by the 1906 treaty between England and Tibet, the Chinese set up about extending westwards the sphere of their direct control and began to colonize the country round Batang.
It was described by Caradja in 1939, and is known from Batang, Sichuan, China, from which its species epithet is derived.
A stone monument regarding the boundary between Tibet and neighbouring Chinese provinces, agreed upon by Lhasa and Beijing in 1726, was placed atop a mountain near Bathang, and survived at least into the 19th century.
