"A phylogeny is developed for those genera of tyrant flycatchers known as the kingbirds and their allies: Pitangus, Megarynchus, Myiozetetes, Conopias, Myiodynastes, Legatus, Empidonomus, Tyrannopsis, and Tyrannus. Monophyly of the assemblage is established by two shared derived character states of the skull. Three putative relatives are excluded from this group: Sirystes sibilator, Machetornis rixosus, and Muscipipra vetula. Generic limits and relationships are determined primarily on the morphology of the syrinx, and secondarily on nesting behavior and external morphology. The enigmatic luteiventris of Sclater (1858) is retained in Myiozetetes on the basis of syringeal morphology and nesting behavior. Although possessing some unique morphological and behavioral characteristics, Legatus is shown to be closely allied with Myiozetetes. Three new monotypic genera are recognized: Phelpsia for Conopias inornata, Philohydor for Pitangus lictor, and Griseotyrannus for Empidonomus aurantioatrocristatus. A classification of the 12 genera recognized in this assemblage might reasonably follow this sequence, based on the relationships demonstrated here: Tyrannus, Empidonomus, Griseotyrannus, Tyrannopsis, Megarynchus, Conopias, Myiodynastes, Myiozetetes, Legatus, Philohydor, Pitangus, and Phelpsia"--P.
