Hitherto treated as conspecific with P. angustifrons, but differs in its dull grey-green vs yellow or black bill (3); olive-green vs brown wings and central uppertail (3); overall palest, most olive head and underparts (1); song consisting of c. 5 well-spaced introductory notes in crescendo with final longer high-pitched note ending abruptly, differing least from songs of P. a. salmoni and P. a. atrocastaneus, which however lack the final note (2)#R. Race P. a. neglectus described as intermediate between present species and other taxa in P. angustifrons#R, but vocally very different; also adults of present species lack yellow on forecrown unlike any form of angustifrons except black-billed nominate. Monotypic.
