No subspecies.
Traditionally placed near Xenops and other bark-gleaning furnariids, but plumage and biogeography suggest that such a relationship unlikely and that any similarities are due to convergence. Possible relationship to Aphrastura suggested by superficial plumage similarities and details of foraging behaviour.
