Taxonomic note
Molecular phylogeny (Päckert et al. 2012) placed this species in a clade with A. niansae, A. bradfieldi, A. barbatus, A. berliozi, A. unicolor, A. pallidus and A. apus. Formerly considered conspecific with A. unicolor; recently suggested as being more closely related to A. niansae, A. barbatus or A. pallidus, although these proposals appear to be based mainly on speculation. Only known eggs, described in 1898, were considered unique among Apodiformes in being speckled reddish-brown; a much later clutch reported in 1986, however, consisted of pure white eggs (like those of other Apodiformes), suggesting that first set was probably misidentified; implications drawn from first eggs have greatly confused the matter of relationships. Monotypic.
