Subspecies
Has been considered a subspecies of Malayan Peacock-Pheasant (Polyplectron malacense), but a phylogenetic analysis of male morphology indicates that it is better treated as a full species. Forms superspecies with Malayan Peacock-Pheasant (Polyplectron malacense) and some authors also include Palawan Peacock-pheasant (Polyplectron napoleonis).
