Ypanema, São Paulo, Brazil.
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. Previously reported hybridization between the two explained as being due to presence of a “residual cline” that reflects geographical variation of the ancestor. Monotypic.
