Until recently considered conspecific with G. chinensis, but split prompted by molecular evidence#R although comparisons failed to include G. c. germaini, the closest in plumage colour. Differs from latter in its black vs white ear-coverts, lower face and submoustachial area (4); all-darkish-brown underparts with no hint of mid-grey on belly (1); notably smaller size (effect size for male wings –2.82, score 2). Monotypic.
