In the past, was at various times considered conspecific with many other swiftlet taxa, e.g. A. francicus and A. unicolor. Race germani sometimes considered a distinct species, often including amechanus; description of it as having “strikingly pale underparts and broad whitish rump” (HBW), however, appears to overstate its distinctiveness, specimens in NHMUK being a shade paler below than nominate fuciphagus and with rump whitish-grey rather than whitish. Races dammermani and micans often lumped within nominate, and still very poorly known. Proposed race bartelsi is a synonym of nominate. A. salangana aerophilus often placed in present species. A. vanikorensis amelis has been linked with present species in a superspecies; race perplexus has been associated with amelis. Eight subspecies currently recognized.
