Hitherto considered conspecific with P. canus and P. dedemi, but differs from former in its deeper, more extensive red on forecrown (2); black hindcrown (with some grey streaking) vs grey hindcrown with vague blackish streaking (3); darker green plumage above (1); reportedly marked vocal differences#R (assume at least 1);  differs from P. dedemi in its green vs bronzy-red upperparts and breast (3), bright yellowish-green vs brilliant red rump (3), and green belly and vent vs bronzy-black mid-belly shading to blackish on belly and vent (2). 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.
