Iquico, 4000 m, La Paz, Bolivia.
In past, sometimes treated as a race of A. pudibunda, but tail structure differs; alternatively, was thought more closely related to and perhaps conspecific with A. ottonis (which see). On basis of plumage and behavioural similarities (avoidance of tail-cocking), has also been suggested to be closest to A. pyrrholeuca, the two having been confused regularly in the field and as museum specimens. Monotypic.
Andes of N Bolivia (S La Paz, Cochabamba, also sight records from Chuquisaca and Tarija) and NW Argentina (Jujuy, Salta, Tucumán).
