Diagnosis.

Females of this species are known by the swollen clypeal margin (Figs 11, 12) (approaching the extreme look found in Osmia bucephala , but unlike in that species, there is no metallic coloration in the integument of the meso- and metasomata). Males are known by the strongly reflexed apicolateral angles of T5 and T6 (Fig. 53). Unlike in Osmia bucephala , the midleg tarsal segments 2-4 are not modified or swollen, and S2 is unmodified (S2 of Osmia bucephala with a low tumescence bordered anteriorly and laterally by several rows of erect bristles).

Distribution.

In the Nearctic, Osmia nigriventris is known from Oregon, Idaho, Wyoming, and Michigan north to Yukon and the Northwest Territories, east across Canada to Ontario, Quebec, and Newfoundland. In the Palearctic, Osmia nigriventris is known from France, Italy, and Slovakia north to Norway, Sweden, and Finland and east to Mongolia, northern China , and through Russia to Far Eastern Siberia ( Müller 2010).

Comments.

Osmia nigriventris is polylectic, with preference for Vaccinium ( Ericaceae ); it nests in old insect burrows in dead wood and constructs cell partitions and nest plugs with chewed leaves ( Müller 2010 and references therein).
