P. L. Sclater, 1860,
Pallatanga, Chimborazo, Ecuador.
Hitherto considered conspecific with P. mystaceus, but differs in its all-dark vs pale lower mandible (3); whiter throat and whiter belly (1); rising vs faster-paced falling series of notes in song, yielding effect size for first-note frequency 6.29 (3) and for frequency evolution 5.1 (3)#R. Race partridgei somewhat intermediate in plumage and voice (vocally closer to present species, song falling and then rising) between present species and P. mystaceus; differs from P. mystaceus in its mostly dark vs pale lower mandible (2), and song with fewer notes (effect size 3.23, score 2), slower pace (effect size 6.67, score 3) and several other differences. Five subspecies recognized.
