Formerly treated as conspecific with H. amaurocephalus, with which partly sympatric, but appears to be clearly differentiated by plumage, eye colour, vocalizations and habitat preference.

SE Brazil (S Mato Grosso do Sul E to Espírito Santo, S to Rio Grande do Sul), E Paraguay and N Argentina (Misiones).
