Osmiine bee material recently collected by A. Fateryga and M. Proshchalykin in Dagestan revealed the following new country records for Russia: Hoplitis (Alcidamea) caucasica, Hoplitis (Alcidamea) scita, Hoplitis (Pentadentosmia) tringa, Osmia (Helicosmia) breviata and Osmia (Osmia) scheherazade
Both sexes of Hoplitis scita from Dagestan have a significantly shorter proboscis than those from Kyrgistan, Siberia (Altai, Buryatia, Khakassia, Tyva), Mongolia and China. In addition, the females from Dagestan have a rather dense whitish hair band on the marginal zone of tergum 5, which is missing in females from the more eastern populations. Otherwise, the morphology (including the male sterna and genitalia), pubescense and colour are identical. Unfortunately, no specimens of H. scita are known from the large geographic area between the Dagestan population and the more eastern populations (e.g. from Kazakhstan) that would allow us to assess whether the intermediate populations have intermediate character states indicating a gradual morphological change. As long as no specimens from Kazakhstan are available, the specimens from Dagestan are tentatively treated as conspecific with specimens of H. scita from Kyrgistan, Siberia, Mongolia and China.
