Amazonian Barred Woodcreeper © oiseaux.net

Until recently considered conspecific with Western Barred Woodcreeper (Dendrocolaptes sanctithomae) but separated on basis of vocal, behavioural and morphological differences. Subspecies concolor sometimes treated as a separate species, but vocal and morphological data suggest that it is instead a pale, weakly barred representative of present species; characters of birds from R Tapajós east to R Tocantins (north-central Brazil), described as subspecies ridgwayi, apparently represent introgression between concolor and medius. Birds from eastern Peru showing characters of polyzonus may instead reflect hybridization between radiolatus and juruanus. One study indicated genetic differences between radiolatus and concolor as great as or greater than those between it and Western Barred Woodcreeper (Dendrocolaptes sanctithomae).

The following 8 subspecies are recognised:

• radiolatus Sclater, PL & Salvin, 1868   -  Western Amazonia, north of Amazon, in south-eastern Colombia, north-western Brazil (west of R Negro), eastern Ecuador and northern and central Peru (largely west of R Ucayali, south to Juní­n).
• certhia (Boddaert, 1783)   -  Northern and north-eastern Amazonia, from extreme eastern Colombia (eastern Guainí­a), southern and eastern Venezuela and the Guianas, south to Amazon in northern Brazil (from R Negro east to Amapá).
• juruanus von Ihering, H, 1905   -  South-western Amazonia, south of Amazon, in eastern Peru, western Brazil (east to R Madeira, south to north-western Mato Grosso) and northern Bolivia.
• concolor Pelzeln, 1868   -  Southern Amazonian Brazil, south of Amazon, from R Madeira east to R Tocantins, south to Mato Grosso and northern Tocantins. Also extreme north-eastern Bolivia. Considered by some authors to be a distinct species, Concolor Woodcreeper (Dendrocolaptes concolor).
• medius Todd, 1920   -  South-eastern Amazonia, south of Amazon, from R Tocantins east to north-western Maranhío; isolated population in north-eastern Brazil (Pernambuco, Alagoas) may no longer exist.
• polyzonus Todd, 1913   -  South-western edge of Amazonia in central Bolivia, possibly extending into adjacent south-eastern Peru.
• retentus Batista et al., 2013   -  Eastern Amazonian Brazil, south of the Amazon, between the Xingu and Tocantins Rivers.
• ridgwayi Hellmayr, 1905   -  Eastern Amazonian Brazil, between the rios Tapajós and Xingu.
