Previously placed in Xenops, but genetic study#R indicates that it is closest to Pygarrhichas and Ochetorhynchus, and basal to them#R, so now returned to its original monotypic genus. Differs from Xenops in bill not being laterally compressed and wedge-shaped, in lacking black in tail and pale malar mark, and also in leg colour, but shares the conspicuous wingband. Monotypic.

Distribution:

SE Colombia (S from Meta and Vaupés), S Venezuela (Amazonas, S Bolívar), S Guyana#R, Suriname and French Guiana S to Amazonian Brazil (S to N Rondônia and SW Pará), E Ecuador, E Peru and NW Bolivia (Pando, extreme NW La Paz).
