In recent times, southern five races commonly split as A. sclateri (as in HBW), but here treated as conspecific because morphological and vocal differences are very slight, with intergradation occurring in region of L Titicaca. Formerly linked with A. anthoides, but molecular evidence#R#R places the two at some distance. Race phelpsi previously listed as perijanus/perijana, but that name now preoccupied, owing to lumping of Schizoeaca into Asthenes#R. Twelve subspecies tentatively recognized.
