Subspecies
Formerly included the taxon meruloides, now considered to be closer to Plain-brown Woodcreeper (Dendrocincla fuliginosa). Subspecies north of R Amazon and east of R Negro (nominate, obidensis) possibly constitute a separate species based on differences in vocalizations, size and iris colour. Further research is required.
The following 7 subspecies are recognised:
bartletti Chubb, C, 1919 - Western Amazonia and upper R Orinoco drainage, both northern and south of R Solimíµes, from central Venezuela and central Colombia, south to eastern Ecuador, eastern Peru, northern Bolivia and western Amazonian Brazil (east to R Negro and R Madeira).
merula (Lichtenstein, 1820) - The Guianas and adjacent northern Brazil (east of R Branco in Roraima and northern Pará).
obidensis Todd, 1948 - Amazonian Brazil, along northern bank of Amazon, from R Negro east to Amapá.
remota Todd, 1925 - Eastern Amazonian Bolivia (northern Santa Cruz), probably also adjacent Brazil (north-western edge of Pantanal).
