Until recently considered conspecific with P. intensior, but differs strongly in both genetics and voice. Races klossi and disturbans have been erroneously placed instead with P. intensior#R#R. Name ogilviegranti (3 Jan 1922) has priority over klossi (3 Oct) and disturbans (27 Oct)#R. Three subspecies recognized.

Subspecies and Distribution
  • P. o. disturbans (La Touche, 1922) – C & SE China (Sichuan, S Gansu and SW Shaanxi S to SE Yunnan, E to S Hunan and Guangdong). Non-breeding in S part of breeding range and in Indochina.
  • P. o. ogilviegranti (La Touche, 1922) – SE China (mountains of NW Fujian and Guangxi, probably also N Guangdong); non-breeding probably Vietnam#R.
  • P. o. klossi (Riley, 1922) – S Laos and SC & S Vietnam.
