Spix's Woodcreeper (Xiphorhynchus spixii) - HBW 8, p. 427

French: Grimpar de Spix German: Spixbaumsteiger Spanish: Trepatroncos de Spix

Taxonomy: Picolaptes Spixii Lesson, 1830, no locality = Pará, Brazil.
Forms a superspecies with X. elegans, the two regarded as conspecific by some authors but treated as separate species in most accounts; recent analyses based on genetic and morphological data support recognition of two species, a monotypic X. spixii and a polytypic X. elegans. Races juruanus and insignis, regarded by most authors as races of X. spixii, and by some as full species, here recognized as races of X. elegans. Monotypic.

Distribution: SE Amazonian Brazil, S of Amazon, from R Tapajós and N bank of R Teles Pires E to N Maranhão (including Marajó I); purported record from Ceará (NE Brazil) involved a misidentified subadult X. picus.
