Previously placed in genus Pterocnemia, on basis mainly of tarsal scutellation and feathered upper tarsus, but genetic studies reveal close relationship with R. americana, and probably more aptly considered congeneric#R#R. Normally considered conspecific with lowland R. pennata, but#R#R differs in having only 8–10 tarsal scutes (3), shorter legs (allow 2), browner upperparts (1) and denser white spots near front edge of “skirt” (1); appears also to intergrade or to be parapatric with R. pennata in Mendoza province, Argentina (possible score 2 or 3), but on other hand plumage variable with age and breeding condition#R; more research needed. Races somewhat variable, and garleppi may not be reliably separable#R#R. Two subspecies tentatively recognized.
