}} }} The family Parulidae was introduced for the New World warblers in 1947 by American ornithologist
Alexander Wetmore and collaborators with
Parula as the
type genus.
Parula is now considered as a
junior synonym of
Setophaga. However, more recent studies recover them as sister to a clade containing just the yellow-breasted chat and the Icteridae, with the clade containing all three families being sister to a clade containing the chat-tanagers in
Calyptophilidae, the wrenthrush, and the
Phaenicophilidae. A
molecular phylogenetic study of the Parulidae published in 2010 found that the species formed several major clades that did not align with the traditional genera. This led to a major reorganization of the species within the family to create
monophyletic genera. The changes have generally followed the recommendations of the authors of the study except in a few cases where the proposed genera were split. A large clade that included the 29 species then placed in the genus
Dendroica, also included four species of
Parula, one of the three species of
Wilsonia and the
monotypic genera
Catharopeza and
Setophaga. All members of the clade apart from
Catharopeza were placed in the expanded genus
Setophaga Swainson, 1827, which under the rules of the
International Code of Zoological Nomenclature, had
priority over
Dendroica Gray, 1842,
Wilsonia Bonaparte, 1838, and
Parula Bonaparte, 1838. The species that had traditionally been placed in
Basileuterus formed two clades. One group retains the genus name as it includes the
golden-crowned warbler, the
type species for the genus. The other larger group, now with 18 species, is placed in the resurrected genus
Myiothlypis Cabanis, 1850, as it contains the type species, the
black-crested warbler. The genus
Myioborus containing the whitestarts remained unchanged after the reorganization but six genera were no longer used:
Dendroica,
Ergaticus,
Euthlypis,
Parula,
Wilsonia and
Phaeothlypis.
Extant Genera The family Parulidae now contains 120 species divided into 18 genera.
