Taxonomy complex, requiring further research; hitherto included S. griseus and its various races, which, when lumped with present species, comprised two out of five groups differentiated on size and plumage. Remaining three groups in fact consist of four when vocal characters added#R: former “griseicapillus group” (breaks into two, “amazonus group” and “griseicapillus group”) of Amazonia and Chaco, monotypic “reiseri group” of NE Brazil, and “sylviellus group” of E & SE South America. These groups may, on rigorous investigation, each represent species. Proposed race viridior, from E Bolivia, barely distinguishable from viridis, perhaps reflecting intergradation between latter and nominate. Eight subspecies recognized.

Subspecies and Distribution
  • S. g. amazonus Lafresnaye, 1850 – Amazonian Woodcreeper – W Amazonia, both N & S of R Amazon, from SE Colombia (S from S Meta, Vichada and Guainía) and S Venezuela (W & S Amazonas) S to E Ecuador, E Peru and N & W Brazil (E to R Negro and R Madeira, S to NW Mato Grosso).
  • S. g. axillaris J. T. Zimmer, 1934 – NE Amazonia N of R Amazon, in SE Venezuela (N & C Amazonas, Bolívar), Guyana, French Guiana and N Brazil (lower R Negro E to Amapá); probably occurs also in Suriname.
  • S. g. transitivus O. M. O. Pinto & Camargo, 1948 – SE Amazonian Brazil S of Amazon, E from at least R Tapajós (probably from R Madeira), S to NE Mato Grosso.
  • S. g. viridis Carriker, 1935 – Amazonian Bolivia (Beni, La Paz, Cochabamba, N & E Santa Cruz).
  • S. g. griseicapillus (Vieillot, 1818) – Chaco Woodcreeper – SE Bolivia (S Santa Cruz SW to Tarija), SC Brazil (SW Mato Grosso, Mato Grosso do Sul) and N & W Paraguay S to NC Argentina (S to Catamarca, Santiago del Estero and N Santa Fe).
  • S. g. reiseri Hellmayr, 1917 – Reiser's Woodcreeper – NE Brazil (S Maranhão, Ceará and Pernambuco S to Tocantins and N & W Bahia).
  • S. g. olivaceus Wied, 1831 – coastal E Brazil (SE Bahia).
  • S. g. sylviellus (Temminck, 1821) – Olivaceous Woodcreeper – SE South America in SE & S Brazil (S from SE Goiás, Minas Gerais and Espírito Santo), SE Paraguay, NE Argentina (Misiones, NE Corrientes) and NE Uruguay.
