E. J. O. Hartert, 1910,
Mt Limu Ling, Hainan.
Until recently considered conspecific with P. reguloides and P. claudiae, but separated on basis of deep molecular divergence#R and vocal differences#R; this arrangement provisionally accepted here (although the taxon currently fails to meet the necessary criteria on the scoring system used herein), pending further evidence on voice, distribution and habitat. Differs from P. claudiae in plumage characters given under that form. From P. reguloides in its striking pale yellowish vs dirtier yellowish breast (2); less white in tail (1); and song apparently lacking introductory notes (1)#R. Two subspecies recognized.
