Tit-tyrants in the genus Anairetes are a group of small, mainly Andean, tyrant flycatchers. It briefly included the genus Uromyias, which formerly was recognized based on syringial and plumage characters, including a flatter crest and a longer tail, but was included within ''Anairetes'' due to genetic analysis.〔〔Remsen, J. V., Jr., C. D. Cadena, A. Jaramillo, M. Nores, J. F. Pacheco, M. B. Robbins, T. S. Schulenberg, F. G. Stiles, D. F. Stotz, & K. J. Zimmer. 2007. (''A classification of the bird species of South America.'' ) American Ornithologists' Union. Accessed 12 December 2007.〕 Recent analyses suggested splitting into Uromyias again.〔DuBay, S.G., Witt, C.C. 2012. An improved phylogeny of the Andean tit-tyrants (Aves, Tyrannidae): More characters trump sophisticated analyses.
