Closely related to A. ellioti; has been considered conspecific, but the two differ in courtship behaviour, song structure, wing morphology, and coloration, and thus merit treatment as separate species. Proposed race morcomi, known from two old specimens from SE Arizona, is a synonym of nominate; presumably based on vagrants, or mislabelled specimens. Two subspecies recognized.
