Until recently, considered conspecific with A. prasinus along with A. wagleri, A. caeruleogularis, A. albivitta and A. atrogularis, but differs from A. albivitta in its almost all-black bill (3), blue vs grey throat (2), and pinkish bare skin under vs all around eye (2). Sometimes suggested as race of A. atrogularis#R, but differs from latter in its almost all-black bill (3), blue vs black throat (2), and pinkish bare skin under eye vs none (2). Monotypic.

Distribution:

E Andean slope of S Ecuador to N Peru (Cajamarca, Amazonas, La Libertad#R).
