Subgenus Stenosmia
Stenosmia Michener was formerly treated as a genus (Michener, 2007; Ungricht et al., 2008). However, in a recent molecular phylogeny of the osmiine bees (Praz et al., 2008b), Stenosmia was found to branch off from within the genus Hoplitis. Therefore, Stenosmia is treated here as a subgenus of Hoplitis. Stenosmia is confined to the Palaearctic region. It contains 10 described species. At least 5 species are still undescribed (Dathe et al., 2009; A. Müller, unpublished).
