Ovenbirds (Furnariidae)

Olive Spinetail (Cranioleuca obsoleta) - HBW 8, p. 295

French: Synallaxe olive German: Braunoliv-Baumschlüpfer Spanish: Curutié Oliváceo
Other common names: Red-tailed Spinetail

Taxonomy: Leptoxyura obsoleta Reichenbach, 1853, Brazil.
Closely related to C. pyrrhophia, and suggested by some as being conspecific; varying degrees of similarity between them in SE Brazil, Uruguay and NE Argentina demonstrated in recent study as indicative possibly of past or current hybridization or perhaps independent variation; further study needed. Both considered by some to form a superspecies that also includes C. subcristata, C. henricae, C. pallida, C. albicapilla, C. antisiensis and C. baroni, but genetic data suggest that at least the last two of those are not part of this lineage.

Proposed race siemiradskii (Paraná, in Brazil) regarded as indistinguishable. Monotypic.

Distribution: E Paraguay, SE Brazil (S São Paulo S to S Rio Grande do Sul), NE Argentina (Misiones, N Corrientes) and E & S Uruguay.
