Ovenbirds (Furnariidae)

Tawny Tit-spinetail (Leptasthenura yanacensis) - HBW 8, p. 265

French: Synallaxe fauve German: Roststirn-Meisenschlüpfer Spanish: Tijeral de Yánac

Taxonomy: Leptasthenura yanacensis Carriker, 1933, Yánac, 15,000 feet [c. 4570 m], Ancash, Peru.
Sister-species relationship with L. fuliginiceps suggested by similarities in plumage and tail pattern; simple plumage pattern and tail structure interpreted as indicating that both occupy a basal position in genus. Population in Cochabamba, in Bolivia, with whitish supercilium and paler underparts than N populations, almost certainly represents an undescribed taxon; specimen material from NW Argentina lacking. Monotypic.

Distribution: W & SE Peru (Ancash, N Lima, and E Andes in Cuzco and Puno) S to N Bolivia (La Paz, Cochabamba, Potosí, Tarija) and NW Argentina (Jujuy, Salta).
