Subspecies
Anatomical data are consistent with the idea that this genus and Premnornis, Premnoplex and Roraimia are each others' closest relatives. Various authors merge one or all of those into present genus. Sister-species to Beautiful Treerunner (Margarornis bellulus), which very likely conspecific. Sight record in north-western Argentina presumably referable to nominate subspecies or, possibly, an undescribed subspecies.

The following 3 subspecies are recognised:

perlatus (Lesson, R, 1844) - Perij� Mts and Andes of western Venezuela (Trujillo, M�rida, T�chira), Colombia (all three ranges), Ecuador, and northern Peru north of R Mara��n (Piura, northern Cajamarca).
peruvianus Cory, 1913 - Andes of northern and central Peru south of R Mara��n (from southern Cajamarca and Amazonas south to Cuzco).
squamiger (d'Orbigny & Lafresnaye, 1838) - Andes of southern Peru (Puno) and Bolivia (south to western Santa Cruz); sight record in north-western Argentina (Salta).
