Until recently considered conspecific with P. aeralatus, but split partly on molecular evidence#R#R and differs in its all-black vs grey mantle to uppertail-coverts in male (3); dull greyish olive-green vs grey crown in female (2); generally smaller size, best indicated by notably shorter tail (effect size in males vs geographically closest P. a. cameranoi and robinsoni combined −4.34, score 2); and evidently different voice#R (allow at least 2); in addition (except vs P. a. annamensis) all-whitish vs part- or all-buff or grey underside in female (1) or (vs P. a. annamensis) vestigial vs strong chestnut in tertials (2). Monotypic.
