Phyllomyias is a genus of small birds in the tyrant-flycatcher family Tyrannidae.
They have a short, stubby bill, are greenish above, yellowish or whitish below, and all except the sooty-headed tyrannulet have pale wing-bars or edging.
The genus Phyllomyias was introduced in 1860 by the German ornithologists Jean Cabanis and Ferdinand Heine.
[2] The type species was subsequently designated in 1888 by Philip Sclater as Platyrhynchus brevirostris Spix, now a subspecies of the Planalto tyrannulet.
A molecular phylogenetic study published in 2020 found that the genus was paraphyletic.
