“…The rest of the range from Greece in the west to Western Kazakhstan in the east and the south of the Saratov Oblast in the north should be inhabited by a nominatypical subspecies, which includes S. tricolor as a junior synonym. However, not all researchers accepted this concept and indicate S. tricolor as a separate species (Schoorl, 1990;Yakovlev, 2007Yakovlev, , 2008aYakovlev, -b, 2019Yakovlev, , 2023Yakovlev et al, 2015;Anikin, 2022). Others agree with the opinion of Freina and Witt and consider S. tricolor a junior synonym (Beshkov, Langourov, 2004;Saldaitis at al., 2007;Yakovlev, 2010a;Alipanah et al, 2021).…”
