Spix

Closely related to P. purpurascens, P. perspicax, P. albipennis and P. obscura. Has been considered conspecific with P. obscura, and formerly with P. purpurascens, but tracheal morphology different. Has hybridized with P. pileata in captivity. Race granti has been considered a separate species, including orienticola as race, but there is extensive intergradation throughout present species. Race speciosa formerly treated as a race of P. obscura. Four subspecies recognized.
