Relationship with P. superciliaris needs confirmation. Distinctive high-altitude race †bogotensis, now extinct, has been suggested (e.g. in HBW) as perhaps a separate species, although some individuals of brevipennis approach it in pattern and coloration#R. Two extant subspecies recognized.

Subspecies and Distribution
  • P. p. bogotensis (Chapman, 1915) – very local in temperate zone in Cundinamarca (savannas of Bogotá) and Valle (upper Dagua Valley), in Colombia (recently extinct).
  • P. p. brevipennis (Berlepsch & E. J. O. Hartert, 1902) – E Colombia, SW, C & SE Venezuela, Guyana, S Suriname, N French Guiana and N Brazil (Roraima, NW Pará, Amapá).
  • P. p. pectoralis (Vieillot, 1817) – E Bolivia (Santa Cruz), S Brazil (locally S from Mato Grosso and S Minas Gerais S to Rio Grande do Sul), Paraguay, N Argentina (S to Mendoza, La Pampa and Buenos Aires) and Uruguay.
