Sometimes placed in genus Agyrtria. Closely related to A. viridifrons, with which formerly considered conspecific. Race ellioti fairly distinctive, with crown turquoise-bluish vs violet-blue and extending farther onto cheeks (2), and uppertail-coverts and tail dull greyish-green to greenish-brown vs burnished bronzy-copper (2); further research desirable. Species name sometimes given as verticalis, but this name refers to A. cyanocephala. Proposed race conjuncta, of Sonora, indistinguishable from ellioti. Described form Cyanomyia salvini, from Nacosari (Sonora), reported to be of hybrid origin (with Cynanthus latirostris), but is probably an aberrant individual of race ellioti. Two subspecies recognized.
