Subspecies
Apparently forms a superspecies with Hoffmanns's Woodcreeper (Dendrocolaptes hoffmannsi) and Planalto Woodcreeper (Dendrocolaptes platyrostris), to which closely allied based on vocal and behavioural characters combined with biogeographical patterns. Subspecies form three groups, occurring in distinct biogeographical regions and differing in morphology: "picumnus group", also including validus and strikingly different transfasciatus (latter sometimes treated as a full species), is primarily Amazonian, but apparently with recent invasion into northern Andes and mountains of southern Central America (multistrigatus and costaricensis); montane "puncticollis group" (also including seilerni and olivaceus) occurs at fringes of species' range; "pallescens group" (with casaresi), found in Chaco region, is regarded by some as constituting a separate species. Single record from northern Argentina (eastern Formosa) may be referable to subspecies pallescens. Described subspecies veraguensis (western Panama) considered inseparable from costaricensis and synonymized with it. Purported subspecies extimus, known only from type locality (R Alto Paraná, in south-eastern Paraguay), is inseparable from pallescens and described from a series of specimens that were probably mislabelled; larger size upon which subspecies casaresi described not supported by recent study. Has apparently hybridized intergenerically with Bar-bellied Woodcreeper (Hylexetastes stresemanni) in western Brazil, one of few cases of possible hybridization in suboscines.
The following 10 subspecies are recognised:
puncticollis Sclater, PL & Salvin, 1868 - Highlands of southern Mexico (Chiapas), central Guatemala and western Honduras.
costaricensis Ridgway, 1909 - Subtropical to lower temperate zones of highlands in central and south-eastern Costa Rica and Pacific slope of western Panama.
multistrigatus Eyton, 1851 - Subtropical to lower temperate zones in Perijá Mts and Andes of Colombia (south to Cauca) and north-western and western Venezuela (Zulia, northern Barinas south to Táchira).
seilerni Hartert & Goodson, 1917 - Tropical and subtropical zones in foothills and highlands of northern Colombia (Santa Marta region) and coastal range of northern Venezuela (Falcón east to Sucre and northern Monagas).
validus Tschudi, 1844 - Lowlands and foothills of western Amazonia, both northern and south of Amazon, in south-eastern Colombia, eastern Ecuador, eastern Peru, northern Bolivia and western Brazil (east to R Negro and R Madeira, and south to Mato Grosso).
picumnus Lichtenstein, 1820 - Lowlands of northern Amazonia, north of Amazon, in southern and eastern Venezuela, the Guianas and northern Brazil (R Negro east to Amapá).
transfasciatus Todd, 1925 - Amazonian Brazil, south of lower Amazon, from R Tapajós east to R Xingu and south to northern Mato Grosso.
olivaceus Zimmer, JT, 1934 - Eastern foothills of central Bolivian Andes (La Paz, Cochabamba, Santa Cruz).
pallescens Pelzeln, 1868 - Chaco region of eastern Bolivia, southern Brazil (western Mato Grosso, western Mato Grosso do Sul) and western Paraguay.
casaresi Steullet & Deautier, 1950 - Subtropical zone of eastern Andean foothills in north-western Argentina (Jujuy, Salta, Tucumán).
