Subspecies
Molecular data support placement as sister to clade including Ocellated Woodcreeper (Xiphorhynchus ocellatus) and Chestnut-rumped Woodcreeper (Xiphorhynchus pardalotus). Considered conspecific with Ocellated Woodcreeper (Xiphorhynchus ocellatus) by most recent authors, but differs morphologically and genetically, supporting treatment by earlier authors as a separate species. Subspecies napensis allied with Ocellated Woodcreeper (Xiphorhynchus ocellatus) by some authors, but external morphology supports original treatment as a subspecies of present species.
Considered by some authors to be a subspecies of Ocellated Woodcreeper (Xiphorhynchus ocellatus).
The following 3 subspecies are recognised:
napensis Chapman, 1924 - Lower Andean slopes and adjacent Amazonian lowlands from southern Colombia (south-eastern Nariño, western Caquetá) south to north-eastern Peru (south to R Marañón).
chunchotambo (Tschudi, 1844) - Lower Andean slopes in eastern and north-eastern Peru (south of R Marañón to Ucayali and Junín).
brevirostris Zimmer, JT, 1934 - Arid interior of north-eastern Brazil (western Bahia).
