Sometimes placed in genus Polyerata or Agyrtria. Closely related to A. lactea. Races fluviatilis, nigricauda and tephrocephala were all previously treated as distinct species. Several proposed races are invalid owing to similar morphology and range overlap with adjacent forms: obscuricauda has proved to be identical to elegantissima; maculicaudus and alia are inseparable from nominate. In Venezuela, the very local form described as A. distans (known only from Táchira) is now thought probably of hybrid origin, present species x Hylocharis cyanus, although sometimes recognized as valid#R. Has been suggested that proposed species A. cyaneotincta, known only from two skins of uncertain origin, is an aberrant form of present species, but this seems unlikely; in plumage pattern it is more similar to A. amabilis. Seven subspecies currently recognized.
