Thought to be closest to A. elaphrus, and sometimes considered conspecific; has alternatively been lumped with A. fuciphagus, although the two do not appear to be closely related. In the past, was treated as part of a composite species that also included A. infuscatus, A. hirundinaceus, A. terraereginae and A. spodiopygius. Differences between birds on Reunion and those on Mauritius suggest that two subspecies may be involved. Monotypic.

Distribution:

Mauritius and Reunion (Mascarene Is).
