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).
