Ovenbirds (Furnariidae)

Chotoy Spinetail (Schoeniophylax phryganophilus) - HBW 8, p. 273

French: Synallaxe damier German: Weißwangen-Dickichtschlüpfer Spanish: Pijuí Chotoy

Taxonomy: Sylvia phryganophila Vieillot, 1817, Paraguay.
Similarities in general morphology and nest structure have led some authors to place this species in Synallaxis, but it differs strongly from all members of that genus in voice and plumage pattern. Isolated race petersi evidently differs only in being smaller, but this requires re-evaluation with modern techniques of analysis. Two subspecies recognized.
