Borba, Rio Madeira, Amazonas, Brazil.
Previously placed in genus Deconychura, but recent extensive phylogenetic analysis#R indicates that present species is sister to a clade consisting of redefined Deconychura, Sittasomus and Dendrocincla; may be closest to Deconychura typica (see below), size and vocalizations of which are more similar to present species than to Amazonian D. longicauda. Race secundus has been considered a separate species by some authors. Racial identity of birds from extreme E of range in Brazil (E of R Tocantins, to Maranhão) uncertain; tentatively included in nominate. Three subspecies recognized.
