New distributional records of Celonites tauricus (Hymenoptera, Vespidae, Masarinae) and new data on its behaviour at flowers

New records of Celonites tauricus Kostylev, 1935 are reported from Chios, Rhodes, Samos (Greece), Dagestan (Russia), Georgia, and the main portion Azerbaijan (previous were made Nakhchivan Autonomous Republic only). Flower visits imagines observed at six species Lamiaceae, four them being recorded for first time as forage plants C. . The newly Teucrium canum Fisch. & C.A. Mey. Ziziphora taurica M. Bieb.
