Andrena (Andrena) inconstans Morawitz, 1877 Andrena (Andrena) bulgariensis Warncke, 1965 syn. nov. Material examined: ARMENIA: Helenowka [Sevan], 1♀, ZISP (lectotype of A. inconstans, illustrated Astafurova et al. 2021); BULGARIA: Situjakowo, Tschertér Tepé, 1730 m, 1–30.iv.1916, 4♀, leg. S.G. Boetticher, OÖLM (holotype of A. bulgariensis, two paratypes); Situjakowo, Tschertér Tepé, 1730 m, 1–30.iv.1917, 2♁, leg. S.G. Boetticher, OÖLM (paratypes of A. bulgariensis); Ljulin Geb. [Liulin], 1000 m, 4.iv.1940, 1♀, leg. B. Pittioni, OÖLM; Melnik, Pirin Mountains, 1–30.vi.1988, 1♀, leg. U. Buchsbaum, TJWC; CRIMEA: Crim, 1♀, OÖLM (paratype of A. bulgariensis); TURKEY: Bolu lake env., 28.iv.1994, 1♀, leg. K. Deneš, OÖLM; Kars, 20 km W of Sarıkamış, 2100 m, 26.v.1980, 5♀, leg. K. Warncke & M. Schwarz, OÖLM; W Sarikamis [Sarıkamış]/ Kars, 31.v.1977, 4♀, leg. K. Warncke, OÖLM. Remarks: Many of the Andrena species described by Morawitz have recently had their type material clarified and illustrated with high-quality photographs (Astafurova et al. 2021; 2022a). This work has clarified the relationship between several obscure taxa nominally known only from the Caucasus versus nominally more widespread West Palaearctic species. Examination of the type photographs of A. inconstans that was described from what are now modern day Armenia and Azerbaijan reveals that this is the senior synonym of A. bulgariensis syn. nov. that was later described by Warncke (1965) from Bulgaria and Crimea. The type specimens are identical, and the distribution of ‘ Andrena bulgariensis ’ extends from Bulgaria across northern Turkey to the Caucasus. Andrena inconstans could therefore be considered to have a circum-Black Sea distribution. Distribution: Bulgaria, Romania, Crimea, Turkey, Armenia, Azerbaijan (Gusenleitner & Schwarz 2002; Wood 2021a; Astafurova et al. 2021).
