Thought unlikely to be related directly to any of the P. torquatus group (which see); recent genetic data indicate that this species is closer to P. castanotis and P. pluricinctus than to P. aracari#R#R. Races flavirostris and mariae have been and are recently again considered to constitute two separate species#R, but characters distinguishing them (distribution of dark markings on the bill) insufficient in number to achieve species rank even with the addition of scores for hybrid zones (both of these and nominate race interbreed wherever they meet#R: mariae with nominate and flavirostris along Amazon, and with flavirostris also in N Peru; flavirostris interbreeds also with nominate on upper R Negro); remarkably, “no appreciable differences among the races in measurements or weight”#R. Race mariae has hybridized with P. humboldti in W Brazil (R Juruá), and hybrid was originally thought to be a distinct species under the name “P. olallae”. Present species, as constituted herein, has sometimes erroneously been named P. flavirostris, apparently owing to confusion over priority. Three subspecies currently recognized.
