Previously included in Brachypus, which may merit resurrection; further study required to clarify relationships. Until recently considered conspecific with P. cinereifrons (see below). Race hachisukae previously referred to by name insularis, but latter (preoccupied by a race of Andropadus importunus, formerly included in expanded version of present genus) replaced before 1961 and thus permanently invalid#R. Races porphyreus, hutzi and hachisukae only dubiously separable (although last two seem reasonably distinct genetically#R); full review required. Other proposed races are chiroplethis (Anamba Is), billitonis (Belitung) and sibergi (Bawean I), all barely distinguishable from nominate. Four subspecies provisionally recognized.
