Oreothlypis is a genus of New World warbler. Most members of this genus for formerly classified in the genus Vermivora. However, the species then in Vermivora were more closely related to the flame-throated warbler and crescent-chested warbler, then classed in Parula, than to other species of Vermivora.[2] Initially, the new genus Leiothlypis was proposed for these species by Sangster in 2008,[3] but the American Ornithologists' Union opted to classify them along with the flame-throated and crescent-chested warblers in the existing genus Oreothlypis, though accepted the change in 2019.[4]
