Hitherto treated as conspecific with A. abeillei, although long speculated to merit species rank; differs in its green vs grey back (3); white preocular supercilium (2); song like abeillei in being two-parted (2–4 notes followed by rapid trill) but trill sharply falling (vs rising) in pitch and covering a large (vs small) frequency range (2+2=4), and song rather shorter (ns)#R. Monotypic.
Upper Marañón Valley in extreme S Ecuador (S Zamora-Chinchipe) and NW Peru (E Cajamarca).
