Tit-tyrants in the genus Anairetes are a group of small, mainly Andean, tyrant flycatchers. The group briefly included the genus Uromyias, which had been recognized based on syringial and plumage characters, including a flatter crest and a longer tail, but was included within Anairetes due to genetic analysis. Recent analyses suggested splitting into Uromyias again. Anairetes is believed to be most closely related to the genera Mecocerculus and Serpophaga; however, there is no definitive evidence supporting this claim.
