The Lesser wagtail-tyrant (Stigmatura napensis), is a species of wagtail-tyrant in the Tyrannidae family. It occurs in two distinct populations: One found in wooded and shrubby habitats along major Amazonian rivers in Brazil, Peru, Ecuador and Colombia, and a second found in the comparable far drier northeastern Brazil. The latter is sometimes considered a separate species, the Bahian wagtail-tyrant (Stigmatura bahiae), named after the state Bahia, where the majority of its range is.
