Subspecies
No subspecies.
Closest relatives of genus may be Empidonomus and Tyrannopsis. Recent molecular-sequence data indicate present genus is monophyletic and sister-group to clade that includes Empidonomus and Griseotyrannus. There are two main clades within genus, loosely corresponding to "tropical species assemblage" and combination of "W" and "E" species groups of earlier authors, but with some exceptions. Appears to be most basal to an expanded "tropical group" that also includes White-throated Kingbird (Tyrannus albogularis), Tropical Kingbird (Tyrannus melancholicus), Couch's Kingbird (Tyrannus couchii), Grey Kingbird (Tyrannus dominicensis) and Fork-tailed Flycatcher (Tyrannus savana).
