The genus was apparently close to the Old World lineages of parrots and might conceivably be assigned to the modern subfamily Psittacinae - either in the strict sense (i.e. including the African parrots and possibly the Asian parrots and parakeets) or in the loose sense (including all psittaciformes except some or all of lories and lorikeets, cockatoos, Nestorinae, kākāpō and Arini), despite its early age. Its lack of apomorphies prevents any better placement until more material is found.[3]
