Forms superspecies with Pink-bellied Imperial-Pigeon (Ducula poliocephala), with which sometimes considered conspecific. Also closely related to Mindoro Imperial-Pigeon (Ducula mindorensis) and Grey-headed Imperial-Pigeon (Ducula radiata). This species-group may form a link between Ptilinopus fruit-doves and other imperial-pigeons. Recently discovered population of Sula Is may represent a distinct subspecies.
