Races intergrade in many areas. Described forms gyldenstolpei (NE Indian Subcontinent), brunneatus and setschuanus (both from Sichuan) and hainanus (Hainan) considered not to warrant separation, although confinement of same subspecies to highly disjunct Taiwan and Hainan appears improbable. Eight subspecies currently recognized.
