Genetic data indicate that present species, P. castanotis and P. pluricinctus form a monophyletic group#R#R, all of these belonging to the P. torquatus group (which see). Contrary to some views, present species probably not closely related to P. azara#R#R. Race atricollis has hybridized with P. pluricinctus in SE Venezuela (Carapo, R Paragua). SE Brazil population previously referred to as vergens, but name wiedii has priority. Other proposed races include roraimae (E Venezuela and the Guianas), synonymized with atricollis; and amazonicus (NC & EC Brazil), now lumped into nominate; poorly known form formosus is something of a mystery, having been synonymized variously with nominate or wiedii, although originally stated type locality is “Venezuela”. Three subspecies currently recognized.
