Formerly placed in genus Leucotreron; a later proposal returned present species to genus Ptilinopus, but within subgenus Leucotreron along with P. alligator, P. dohertyi and P. porphyreus; these four species appear to be closely related; genetic data support link at least with P. porphyreus#R. Present species is the sister-taxon of P. alligator, and these two forms are considered conspecific by some authorities; more work needed to clarify this issue. Distinctive race albocinctus (along with doubtfully valid baliensis#R) has nape, neck-sides, throat and breast grey vs yellowish-white, but form everetti intermediate in both coloration and geographical range. Six subspecies recognized.
