Osmia novaescotiae Cockerell, 1912: 355 [♀]
Holotype ♀. CANADA, Nova Scotia, by Ent. Club, 1844 [BMNH (44-12 Cockerell accession number)]
It is likely that this is not a valid species, and Cockerell (1912) suggested its was likley the female of O. simillima Smith; he indicated that the female in the syntype series described by Smith may not be true O. simillima, and may be O. caerulescens (an introduced species). Cockerell (1912), based on Robertson (1903) indicated that the female of O. simillima was an Osmia s.str. [Sandhouse (1939) indicated it was actually O. (Melanosmia) distincta Cresson], while the male was a member of Monilosmia (i.e., Melanosmia). Sandhouse (1939) indicated that Robertson originally made an error associating the female to the male based on rearing of O. simillima by Graenicher.
