Usually considered conspecific with P. viridis and P. dextralis; P viridis differs in its green middle and lower mantle (3); conspicuous iridescent purple hindneck (2); conspicuous iridescent purple outer wing-coverts (ns[2]); pale bill and legs (3); possibly larger bill (inadequate sample in published manual#R) (ns); P. dextralis differs in its mid-brown shading to olive-brown vs dark brown shading to dark green mantle (3); virtual absence of colour vs some colour on hindneck (2); virtual absence of colour vs some colour on outer wing-coverts (2); possibly larger bill (inadequate sample in published manual#R) (ns). Molecular evidence supports its separation#R. Monotypic.
