Sometimes treated as a race of P. rufiventris. All races at least moderately distinctive and johni particularly well marked, leading to its occasional treatment as a separate species#R#R, but recent claim for its vocal distinctiveness#R not well supported by analyses of available sound recordings, which reveal that it possesses a far greater variety of song phrases, many shared with other taxa, than supposed#R; moreover, the taxonomic elevation of this centrally placed form appears invidious, and it may be better to wait until further work on all taxa can elucidate the number and degree of differences among them. Six subspecies recognized.
