Ovenbirds (Furnariidae)
Ruddy Spinetail (Synallaxis rutilans) - HBW 8, p. 280
French: Synallaxe ardent
German: Schwarzkehl-Dickichtschlüpfer
Spanish: Pijuí Rojizo
Other common names: Temminck’s Spinetail
Taxonomy: Synallaxis rutilans Temminck, 1823, Cametá, Rio Tocantins, Brazil.
Almost certainly the sister-species of S. cherriei, type specimen of which was once considered an aberrant individual of race amazonica of present species. Distinctive race omissa suggested as being possibly a separate species. Differentiation and distribution of other races uncertain, and present arrangement tentative; some listed races possibly not distinguishable, while small series of specimens from N Bolivia suggests that darkness of plumage coloration varies clinally from W Amazonia to extreme E Bolivia (near type locality of tertia); thorough analysis needed..

Almost certainly the sister-species of S. cherriei, type specimen of which was once considered an aberrant individual of race amazonica of present species. Distinctive race omissa suggested as being possibly a separate species. Differentiation and distribution of other races uncertain, and present arrangement tentative; some listed races possibly not distinguishable, while small series of specimens from N Bolivia suggests that darkness of plumage coloration varies clinally from W Amazonia to extreme E Bolivia (near type locality of tertia); thorough analysis needed. Seven subspecies recognized.
