Some authors have treated the rusty-fronted canastero (A. ottonis) and maquis canastero (A. heterura) as subspecies of the canyon canastero and others have treated the three as a superspecies. However, genetic data show that the canyon canastero is most closely related to the Vilcabamba thistletail (A. vilcabambae). == Description == The canyon canastero is 15 to 17 cm (5.9 to 6.7 in) long and weighs 13 to 17 g (0.46 to 0.60 oz). The sexes have the same plumage. Adults of the nominate subspecies have a thin buff supercilium and dark brownish lores on an otherwise gray-brown face.

Their uppertail coverts are chestnut-rufous and their tail a more rufous brown than the back. Their chin and upper throat are pale tawny-orange, their…
