Abstract: Acantholycosa sterneri (Marusik, 1993) Figs 5, 6, 13 Pardosa sterneri Marusik, 1993: 77, figs 1–3 (♂). Acantholycosa sterneri: Kronestedt and Marusik 2002: 67, figs 2, 7, 8, 12, 13, 15–18, 21, 25–27 (♂ ♀); Marusik et al. 2004: 113, figs 66–72 (♂ ♀); Marusik and Omelko 2017: 599, fig. 12 (♂). Material examined. China: • 1 ♂, Inner Mongolia, Chifeng City, Balinyou Co., Saihanwula National Nature Reserve, top of Hanshan Mt., 44°10'27"N, 118°44'2"E, elev. 1828 m, 27. 06. 2015, Z. S. Zhang and L. Y. Wang leg. • 1 ♀, Saihanwula National Nature Reserve, 44°18'96"N, 118°75'31"E, elev. 1941 m, 15. 08. 2023, S. T. Shi et al. leg. • 1 ♂, Balinyou Co., Wulanba Mt, 44°26'33"N, 118°42'8"E, elev. 1846 m, 11.07. 2023, K. Yu et al. leg. Diagnosis. Acantholycosa sterneri is similar to A. solituda (Levi & Levi, 1951) (Kronestedt and Marusik 2002, figs 1, 3–6, 9–11, 14, 19, 20, 22–24) in having a similar conformation of the copulatory organs (Figs 5 A – D, 6 C – H), but it can be differentiated by the median apophysis with a reduced apical arm (Figs 5 A, 6 C, E) (vs. without apical arm); embolus basal part wider than apical part (Figs 5 A, 6 C, E) (vs. embolus basal part as wide as apical part); embolus with pointed tip ventrally (Figs 5 A, 6 C, E) (vs. blunt). Females can be distinguished by the septal width measuring 1.3 times its length (Figs 5 C, 6 G) (vs. 2.3 times its length), and spermathecae separated (Figs 5 D, 6 H) (vs. spermathecae close together). Description. See Kronestedt and Marusik (2002). Habitus as shown in Figs 6 A, B, male palp as in Figs 5 A, B, 6 C – F, epigyne as in Figs 5 C, D, 6 G, H. Distribution. China (Inner Mongolia), Russia (South Siberia), Mongolia. Comment. This species belongs to the A. solituda - group.
