Was considered a separate species in the past, but recent trend has been to lump with A. sulcatus on grounds of vocal similarity and intergradation#R. However, highly distinctive in bill morphology, with yellow replacing red (3), black distributed differently (2) and length greater (effect size 2.53; score 2); moreover, tail also longer (ns) and zone of intergradation narrow (2). Recent molecular study#R indicated that it is nested within sulcatus but also found it monophyletic. Also closely related to A. albivitta, with which range overlaps somewhat. Monotypic.

Distribution:

NE Colombia (Santa Marta and Perijá Mts) E into W Venezuela (E to SW Lara).
