Lafresnaye’s Woodcreeper (Xiphorhynchus guttatoides)

Until recently considered conspecific with X. guttatus and previously also with X. susurrans (see both species). New molecular review#R proposes that these be treated as three full species, which also present subtle differences in morphology and vocalizations. The “eytoni group”, sometimes considered a separate species, is also distinct vocally; but molecular data suggest that this group and “guttatoides group” form a monophyletic clade, a hypothesis supported by fact that vicinalis is phenotypically and genetically intermediate between guttatoides and eytoni. Birds in N Bolivia, placed in dorbignyanus, show signs of intergradation with nominate. Birds of Ceará often treated as race gracilirostris, but appear inseparable from eytoni#R. Four subspecies recognized.

Subspecies and Distribution
  • X. g. guttatoides (Lafresnaye, 1850) – Lafresnaye's Woodcreeper – W Amazonia both N & S of Amazon, from SE Colombia (S from Meta and Guainía), S Venezuela (W & S Amazonas) and E Ecuador S to E & SE Peru, NW Brazil (E to R Negro and R Madeira, S to N Mato Grosso).
  • X. g. dorbignyanus (Pucheran & Lafresnaye, 1850) – C South America S of Amazon Basin, from N & E Bolivia (La Paz, Beni, Cochabamba, Santa Cruz) E to EC Brazil (E to C Goiás).
  • X. g. vicinalis Todd, 1948 – Amazonian Brazil S of Amazon, from R Madeira E to R Tapajós (where possibly on both banks); specimens from sites N of Amazon likely either mislabelled or misidentified.
  • X. g. eytoni (P. L. Sclater, 1854) – Dusky-billed Woodcreeper – SE Amazonian Brazil from R Tapajós E to W Maranhão; also Serra do Baturité, in Ceará (NE Brazil).
