Formerly placed in genus Zenaidura, along with Z. auriculata and Z. macroura, and these three are clearly close relatives, as confirmed by genetic evidence#R. Until recently considered conspecific with Z. macroura, but captive studies revealed distinct differences in visual displays and vocalizations; the two species mate assortatively in captivity; hybrids produced by cross-fostering present species under Z. macroura, with resultant sexual imprinting on the latter. Differs from all forms of Z. macroura in all-rufous underparts including undertail-coverts (3), much reduced or no glossy neck-patches (3), and larger foot and bill size (at least 1). Monotypic.
Formerly Socorro I in Revillagigedo Archipelago (off W Mexico); now extinct in wild.
