Considered sister to A. goeldii#R#R, with similarities in morphology and voice, although differences in location of hidden white patches and possibly in nest architecture may indicate more distant relationship; the two appear to be sympatric in Brazil along upper R Juruá (Acre). Form described as “Akletos peruvianus” later identified as female of present species. Monotypic.

Distribution:

SE Colombia (Meta, Caquetá, Putumayo, S Amazonas), E Ecuador, NE & EC Peru (Loreto, Amazonas, N Ucayali) and W Amazonian Brazil (E to R Japurá and to both banks of R Juruá).
