Subspecies
Forms superspecies with African Swift (Apus barbatus), Forbes-Watson's Swift (Apus berliozi) and Pallid Swift (Apus pallidus). It has been suggested that resemblance to Mottled Swift (Tachymarptis aequatorialis) may be more than superficial, hinting at closer alliance between these forms, which were formerly considered conspecific.
The following 2 subspecies are recognised:
bradfieldi (Roberts, 1926) - South-western Angola and Namibia.
deserticola Brooke, 1970 - Northern Cape (South Africa).
