Proposed race mulleri is synonym of nominate, and indeed species formerly listed as T. mulleri; birds of Banggai have been awarded race incognitus, based on supposedly different iris colour, but data are from unreliable specimen labels. Form described as T. heterurus (Rufous-tailed/Salvadori’s Parrot) based on an aberrant specimen of present species#R. Race sangirensis sometimes included within nominate. Six subspecies recognized.
