Subspecies
In Collar et al. (1992, 1994), Asthenes dorbignyi (Sibley and Monroe 1990, 1993) was split into Creamy-breasted Canastero (Asthenes dorbignyi), Pale-tailed Canastero (Asthenes huancavelicae) (including Asthenes usheri, a form previously considered specifically distinct in Collar and Andrew 1988) and Dark-winged Canastero (Asthenes arequipae) following Fjeldså and Schulenberg (unpublished manuscript). However, evidence for the separate status of Pale-tailed Canastero (Asthenes huancavelicae) and Dark-winged Canastero (Asthenes arequipae) was considered insufficient for them to be recognised by Remsen (2003) and Remsen et al. (2005), and thus dorbignyi, huancavelicae and arequipae have subsequently been lumped back into Creamy-breasted Canastero (Asthenes dorbignyi) following Sibley and Monroe (1990, 1993).
usheri Morrison, 1947 - Andes of south-central Peru (Apurímac). Considered by some authors to be a distinct species, White-tailed Canastero (Asthenes usheri).
huancavelicae Morrison, 1938 - Andes of western and south-central Peru (locally in Ancash, also Huancavelica and Ayacucho). Considered by some authors to be a distinct species, Pale-tailed Canastero (Asthenes huancavelicae). Considered by some authors to be a subspecies of Creamy-breasted Canastero (Asthenes dorbignyi).
