(Apodidae; Ϯ White-collared Swift S. zonaris) Gr. στρεπτος streptos  collar, neck-chain  < στρεφω strephō  to twist; myth. Prokne, who was metamorphosed into a swallow (see Progne); "The name Hemiprocne must therefore unfortunately supplant the later Macropteryx Swainson   ...  The genus of large collared swifts that commonly has been called Hemiprocne must, if generically separable from Chaetura, consequently be given a new name.   ...   In view of all the above facts it seems proper to provide this group with a generic name, and Streptoprocne, from ςτρεπτος, torquis, and Προκνη, Progne, with Hirundo zonaris Shaw as the type, is suggested as appropriate." (Oberholser 1906).
Var. Streptoprocnes.
Synon. Semicollum.
