Taxonomy: Muscicapa risora Vieillot, 1824, Rio Grande do Sul, Brazil.
Genus appears to be most closely allied to Fluvicola and Arundinicola. Present species formerly placed in a monotypic genus, Yetapa, on basis primarily of exaggerated tail and elongated hallux; it does, however, have very similar plumage pattern to that of A. tricolor, with which it shares highly modified outer rectrices and numerous other derived features unique within the family. Monotypic.

Distribution: S Brazil (locally S Mato Grosso, São Paulo, Rio Grande do Sul), N Argentina (E Formosa and Misiones S to Córdoba and N Buenos Aires), E Paraguay and Uruguay.
