DEFINITIONS

APUS
(Apodidae; Ϯ Common Swift A. apus) Specific name Hirundo apus Linnaeus, 1758; "APVS. BELLON. Alæ arcuatæ, ultra caudam sedentis extensæ. Nares ellipticæ, duplicatura in exteriore cantho instructæ. Mandibula utraque apice deflexa. Digiti quatuor, omnes anticis.  HIRVNDO Apus. LINN." (Scopoli 1777); “Three generic names have been used at various times for the Swifts. Apus Scopoli  ...  is preoccupied by Apos, introduced by the same author on p. 404 for a genus of Crustaceans. As these names are identical except for the interchange of “o” and “u,” the earlier one only is valid. The second is Micropus Meyer & Wolf [1810]  ...  This has been rejected by Sharpe (Hand-List, ii. 1900, p. 95), as the same name was applied to a genus of plants by Linnaeus, but under the present rules this no longer renders a name invalid for zoology, and Micropus should therefore be used. The third name, Cypselus Illiger, 1811, was used in the 1^st edition of the List and by most of the earlier authors” (BOU 1915); "Apus Scopoli, Intr. Hist. Nat., 1777, p. 483. Type, by tautonymy, Hirundo apus Linné.¹   ...   ¹ Not preoccupied by Apos Scopoli, 1777, Crustacea.  Replaces Cypselus Illiger, 1811, of Sharpe's Hand-list and Micropus Meyer and Wolf, 1810, of many recent authors." (Peters, 1940, IV, p. 244).   
Synon. Apodium, Brachypus, Brevipes, Caffrapus, Colletoptera, Cypselus, Drepanis, Epicypselus, Micropus, Tetragonopyga.
