Holotype ♂ (MHBU-ARA-2023-814-1), CHINA: Xizang Autonomous Region, Rigaze City, Dingkye County, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=87.415215&amp;materialsCitation.latitude=27.874842" title="Search Plazi for locations around (long 87.415215/lat 27.874842)">Zhentang Town</a> (27°52′29.43′′N, 87°24′54.78′′E, alt. 2271.7 m), 16 July 2023, leg. Xiangbo Guo and Haibin Zhang.</p><p>Paratype: 1♀ (MHBU-ARA-2023-814-2), with same data as holotype .</p><p>Etymology. The specific name refers to Hongshan Jade Dragon, a national cultural relic of China, whose C- shape resembles this species spermatheca. Noun in apposition.</p><p>Diagnosis. The new species resembles S. orientalis and S. cona in the shape of palpal bulb and conductor, and absence of RTA (see Sierwald 1993; Wang et al. 2024), but it can be distinguished from S. orientalis by: 1) the width of the median apophysis over half that of the bulb in ventral view (Fig. 2A) vs. less than half the width (Sierwald 1993: figs 20, 22); 2) copulatory openings semicircular, located at posterior edge of epigyne (Figs 4A–C) vs. circular, located in the middle of epigyne (Sierwald 1993: fig. 15); 3) stalk of spermatheca bent inwards (Fig. 4B) vs. bent upwards (Sierwald 1993: fig. 16). It differs from S. cona in: 1) the median apophysis divided into two branches (Figs 2, 3A, C) vs. unbifurcated (Wang et al. 2024: figs 2A, 3A); 2) the outer margin of membrane between tegulum and median apophysis relatively smooth (Figs 2A, 3C) vs. arched (Wang et al. 2024: figs 2A, 3A, C); 3) the head of spermatheca spherical, visible in the dorsal view of vulva (Fig. 4B) vs. cylindrical, half hidden behind the stalk of spermatheca (Wang et al. 2024: figs 2D, 3G).</p><p>Description.
