M. H. C. Lichtenstein, 1823,
Cametá, Pará, Brazil.
SE populations sometimes split as race araguayae (as in HBW), but recent study#R reveals main distinguishing character (longer white tips of rectrices) to be result of clinal variation, while size of white edges on scapulars (supposedly broader on araguayae) shows extensive individual variation. Same study found that form hagmanni, long treated as junior synonym of present species, is distinctive and may represent a separate species; further investigation needed. Monotypic.
C & E Amazonian Brazil, on both banks and along S tributaries, from EC Amazonas E to Pará and Tocantins and S to NE Rondônia, N & SE Mato Grosso and Goiás.
