5E065B9A0A5859D59DAD378D1BF30D48.taxon	diagnosis	Diagnosis. Females of E. lavrosii are similar to those of E. moravicus Řezáč, 2008 by a pars cephalica covered with dense short yellow hair and a uniformly black abdomen. They can be distinguished from E. moravicus by femora I – IV ventrally and sternum with yellow and off-white macrosetae (vs. completely black) (Figs 3 D, 4 F – G; cf. Kovács et al. 2015: fig. 1 C; personal communication with Gábor Kovács), shorter and wider epigyne, significantly wider and more extensive median lobe (Fig. 2 A, C), more globular anterior sections of copulatory ducts (vs. more oval-shaped), longer epigyne fissures with almost straight anterior tips (vs. shorter and strongly bent (Fig. 2 B, D; cf. Kovács et al. 2015, fig. 5. C – D), and yellow setae not reaching the middle line of pars cephalica (Fig. 4 D) (vs. closing in the middle line, Kovács et al. 2015, fig. 1 C; Kovács et al. 2010, fig. 2 E).	en	Seropian, Armen, Bulbulashvili, Natalia, Makharadze, Giorgi, Kovács, Gábor (2025): From burrows to spotlight: first description of the female of Eresus lavrosii Mcheidze, 1997 (Araneae, Eresidae), with notes on the natural history.

5E065B9A0A5859D59DAD378D1BF30D48.taxon	description	Description. Total length 14.21. Carapace 7.25 long, 5.38 wide. Carapace: dark red-brown in alcohol; black in live specimen; pars cephalica and pars thoracica nearly equally wide; pars cephalica elevated, anteriorly covered with dense yellow setae. Chelicerae with dense yellow setae, covering ca. ½ of cheliceral length. Legs dark brown, with a thin yellow ring of setae at joints. Fe I ventrally with yellow macrosetae. Leg measurements are given in Table 1. Epigyne and vulva as in Figs 2 A – D: median lobe subtrapezoidal; epigynal fissures (EF) anteriorly and posteriorly diverging; anterior section of copulatory ducts (ACS) oval, closely situated; spermathecae (S) broad and convoluted, forming numerous small lobes, slightly extending further laterally than ASC. Male. See Mcheidze (1997); Zamani et al. (2020); see “ Note ” below. Habitus as in Fig. 4 C. Bulbus as in Figs 2 E – G.	en	Seropian, Armen, Bulbulashvili, Natalia, Makharadze, Giorgi, Kovács, Gábor (2025): From burrows to spotlight: first description of the female of Eresus lavrosii Mcheidze, 1997 (Araneae, Eresidae), with notes on the natural history.
