Ocellated Woodcreeper (Xiphorhynchus ocellatus) - HBW 8, p. 426

Taxonomy: Dendrocolaptes ocellatus Spix, 1824, Piauí; error = mouth of Rio Madeira, Amazonas, Brazil.
Molecular data support placement as sister to X. pardalotus, to the exclusion of X. chunchotambo. Considered conspecific with X. chunchotambo by most recent authors, but morphological and genetic differences support original treatment as a separate species; race napensis treated here within X. chunchotambo, despite suggestion by some authors that it may be closer to X. ocellatus. Race weddellii considered synonymous with nominate by most authors, but genetic and vocal data support treatment as a separate taxon; nomenclature complicated, however, by fact that type specimens of the two were found to be identical when compared directly and, in addition, precise locality data are lacking for both. Range of lineatocapilla uncertain; taxon known only from unique type, said to be from Ciudad Bolívar, in C Venezuela, but that evidently erroneous. A thorough taxonomic review is badly needed for this poorly known species. Four subspecies recognized.
