New species records for France

Matthieu Aubert recently discovered Osmia (Pyrosmia) nana and Osmia (Melanosmia) steinmanni in the Mercantour national park in southeastern France. These two species have never been found in France before. For O. nana it is the westernmost record known so far. The new record of O. steinmanni, which was  known only from a few localities in Switzerland and one locality in South Tyrol, indicates that this very rare species has a wider distribution than hitherto assumed.
