Molecular work demonstrates that present species is close to A. quinquestriata (which was formerly placed in Aimophila). ­Several other races proposed: dapolia (described from Chisos Mts, Texas) included in opuntia; in SW Gulf of California, carmenae (Carmen I) and sanctissima (Espíritu Santo I) both synonymized with bangsi; confinis (Chihuahua Municipality, C Chihuahua) treated as a synonym of grisea. Nine subspecies recognized.
