Until recently considered conspecific with A. subulatus, but differs in its duskier underparts, with pale flammulations more confined to upper breast (1); slightly darker chestnut tail (1); and highly divergent song#R, a series of evenly spaced identical short staccato notes, “keek..keek..keek..keek”, vs a series of just a few (usually 2–3) downslurred notes, often (perhaps when excited) followed by a low-pitched rattle, hence fewer (ns[1]) and much shorter notes (3) with a double peak frequency (at least 2). Four subspecies recognized.
