Plumage and distribution suggest that closest relative of genus is Philydor. Proposed race cognitus, from lower R Tapajós (Brazil), described as more ochraceous and paler above, more buffy below, particularly throat, which has fewer dusky spots, with supercilium more buff; these characters, however, bridged by individual variation in series from farther W. Monotypic.

Distribution: SE Colombia (S from S Meta and W Vaupés), E Ecuador, E Peru, Amazonian Brazil (mostly S of R Amazon, E to lower R Tapajós) and N Bolivia (Pando, La Paz).
