Closely allied to L. schach, and formerly treated as conspecific, but differs in morphology; the two species are largely sympatric and, although race lahulensis sometimes thought to represent a hybrid population between them#R, no definite proof of interbreeding. Two subspecies recognized.

Subspecies and Distribution
  • L. t. lahulensis Koelz, 1950 – N Kashmir E to CN India (Uttarakhand), and probably SW China (W Xizang).
  • L. t. tephronotus (Vigors, 1831) – Nepal E to NE India (Arunachal Pradesh), and C & S China (S Gansu, Ningxia and E Shaanxi S to SE Qinghai, S & E Xizang, SE Yunnan and C Guizhou); non-breeding also S to N India, Bangladesh, Myanmar, Thailand and Indochina.
