REMARKS. Endemic to the western Caucasus, found in the Krasnodar and Stavropol territories, Adygea and Georgia [ Read, 1992; Evsyukov et al., 2022; Zuev, 2014, 2021]. It has hitherto been recorded only from the Urupsky District of Karachay-Cherkess Republic [ Read, 1992]. The new illustrations reflect variations in the shape of the telson (Figs 9–11).
