Buntings and New World Sparrows (Emberizidae)

Buff-throated Warbling-finch (Poospiza lateralis) - HBW 16, p. 625

French: Chipiu à croupion roux German: Rotbürzel-Ammerfink Spanish: Monterita Culirrufa
Other common names: Red-rumped Warbling-finch (when treated as conspecific with P. cabanisi)

Taxonomy: Fringilla lateralis Nordmann, 1835, Rio de Janeiro, Brazil.
New molecular data indicate that genus forms a clade with the tanager (Thraupidae) genera Hemispingus and Thlypopsis, and that Compsospiza, which often subsumed within present genus, is sister to that clade. Closest relatives of present species uncertain; further study required. Until recently thought to be conspecific with P. cabanisi, but separated on basis of differences in song and plumage. Monotypic.

Distribution: Mountains of Espírito Santo, Rio de Janeiro, N São Paulo and adjacent parts of Minas Gerais, in SE Brazil.
