Coelioxys banksi Crawford, 1914: 155 [♀].

     Holotype . USA, Virginia, Falls Church, 20 August [no year provided], by N. Banks [USNM no. 18221].

Coelioxys angulifera Cockerell, 1916: 61 [♀, ♂] [synonymy by ].

     Holotype . USA, California, Clairmont, by Baker [Pomona coll. 195] [XXX].



Cockerell (1916: 62) considered that his C. angulifera Cockerell was possibly a race of C. banksi Crawford, though separated from that species “by the whole breadth of the country”. However, he (Cockerell 1925: 148) and others (e.g., Linsley 1951: 1183) continued to treat it as a valid species.



This species is a nest parasite of Megachile relativa (Medler and Koerber 1958).
