Tre nye arter af bier for den danske fauna (Hymenoptera, Apoidea)

Since the latest update of the checklist on bees known from Denmark, the following three species have been added as new to the country: Colletes halophilus Verhoeff, 1943 (Colletidae), Nomada obscura Zetterstedt, 1838 (Apidae) and Xylocopa violacea (Linnaeus, 1758) (Apidae). The national checklist hereby includes 286 bee species, but more species will probably be found in the future, as the wild bee fauna in Denmark has never been thoroughly investigated
