88BAEDA882A95197A63B448DC044026E.taxon	diagnosis	Diagnosis. The new species belongs to the sandaliatus group sensu Zamani et al. (2025). In the overall shape of the conductor (Cn) and the general coloration pattern of the body and appendages, it most closely resembles E. kollari and E. hermani. It can be distinguished from E. kollari by its more robust terminal tooth (TT) having a distinct bulge (Figs 2 C, F, I, L, 3 C, F cf. Miller et al. 2012: fig. 43 J). From E. hermani, it differs in the conductor distinctly longer than wide in retrolateral view (vs. almost as long as wide; Figs 2 C, F, I, L, 3 C, F cf. Kovács et al. 2015: fig. 3 B).	en	Zamani, Alireza, Seropian, Armen, Zarikian, Noushig, Bulbulashvili, Natalia, Szűts, Tamás (2025): Different, but still the same: integrative taxonomy confirms a new species of Eresus Walckenaer, 1805 (Araneae, Eresidae) from the South Caucasus.
