Alpine Swift Apus melba and Mottled Swift Apus aequatorialis are now placed in the genus Tachymarptis, as Tachymarptis melba and Tachymarptis aequatorialis respectively, based on morphological and feather louse differences (Brooke 1970, 1972) and phylogenetic data (Päckert et al. 2012), and now aligning with e.g., Gill and Wright (2006, IOC v.1.0).
