Etymology. The specific epithet is taken from the Qin Dynasty, the first unified and centralized feudal dynasty in Chinese history, established by the first emperor of China: Qin Shi Huang; noun in apposition.

Diagnosis. The new species resembles S. agoriformis Strand, 1906 , S. zhilcovae Prószynìski, 1979 and S. subagoriformis Wang, Li & Peng, 2021 , but differs from them in the following characters: male: (1) the retrolateral tibial apophysis is prong-like and slightly curved dorsally ( Figs 10D View FIGURE 10 , 12B View FIGURE 12 ; whereas it is slightly curved ventrally at its tip in S. agoriformis , see Omelko & Fomichev 2021: fig. 17; it is absent in S. subagoriformis ; see Li et al. 2021: fig. 4B, D); (2) the dorsal cymbial apophysis is distinct, and curved toward the distal end of the cymbium ( Figs 10C, D View FIGURE 10 , 12B View FIGURE 12 ; whereas it is not distinct in S. agoriformis , S. zhilcovae and S. subagoriformis , see Omelko & Fomichev 2021: figs 15, 17, 18, 20 and Li et al. 2021: fig. 4A, B); (3) the embolus is more than half the height of the bulb and slightly curved ( Figs 10A View FIGURE 10 , 12A View FIGURE 12 ; whereas it is highly curved in S. agoriformis , see Omelko & Fomichev 2021: fig. 16; it is less than half the height of the bulb in S. subagoriformis , see Li et al. 2021: fig. 4C); (4) the prolateral distal branch of the median apophysis slightly tapers towards a pointed tip level with the ventral cymbial apophysis ( Figs 10A View FIGURE 10 , 12A View FIGURE 12 ; whereas it is blunt in S. agoriformis , see Omelko & Fomichev 2021: fig. 16; its tip is lower than the ventral cymbial apophysis in S. zhilcovae , see Omelko & Fomichev 2021: fig. 19; it is lacking in S. subagoriformis , see Li et al. 2021: fig. 4C); (5) the prolateral proximal branch of the median apophysis is long, with its tip level with the point where the coiled base of embolus begins to taper ( Figs 10A View FIGURE 10 , 12A View FIGURE 12 ; whereas it is short and does not extend to the coiled base of embolus in S. agoriformis and S. zhilcovae , see Omelko & Fomichev 2021: figs 16, 19); female: (1) the spermathecae are elongated, and the combined width of the two exceeds two-thirds of the epigynal width ( Figs 11A–D View FIGURE 11 , 12C, D View FIGURE 12 ; whereas they are less than two-thirds in S. agoriformis , S. zhilcovae and S. subagoriformis , see Omelko & Fomichev 2021: figs 33, 34, 39, 40 and Li et al. 2021: fig. 5A–C); (2) the length of each accessory gland is close to half of the spermatheca, extending to both sides, the tips are close to the endpoints of the spermathecae ( Figs 11A–D View FIGURE 11 , 12C, D View FIGURE 12 ; whereas it is extremely short compared to the already short spermatheca in S. agoriformis and S. subagoriformis , see Omelko & Fomichev 2021: figs 33, 34 and Li et al. 2021: fig. 5A–C; it is over half of the spermatheca, and the tip extend beyond the endpoints of the spermatheca in S. zhilcovae , see Omelko & Fomichev 2021: figs 39, 40). The new species is also very similar to S. hubeiensis Peng & Li, 2008 , but its dorsal abdomen lacks two lateral light-colored spots in the anterior half, and the transverse bands close to the posterior end are not obvious ( Fig. 9A View FIGURE 9 ; whereas the dorsal abdomen has two lateral light-colored spots in addition to the two pairs of spots close to midline, and the transverse bands close to the posterior end are obvious in S. hubeiensis ; see Peng et al. 2008: fig. 15). In addition, the male palp differs from that of S. hubeiensis in: (1) the ventral femoral apophysis is sub-triangular and wide ( Fig. 10E View FIGURE 10 ; whereas it is tapered and curved at tip in S. hubeiensis ; see Peng et al. 2008: figs 17, 19); (2) the tip of dorsal cymbial apophysis is rounded in dorsal view, with the distal edge not curved ( Fig.10B View FIGURE 10 ; whereas it is slightly pointed in dorsal view, with the distal edge curved in S. hubeiensis ; see Peng et al. 2008: fig. 18); (3) the prolateral proximal edge of the bulb is smooth without any indentation in ventral view ( Figs 10A View FIGURE 10 , 12A View FIGURE 12 ; whereas it is indented in S. hubeiensis ; see Peng et al. 2008: fig. 16); (4) the proximal edge of the bulb forms an obtuse angle in retrolateral view ( Figs 10D View FIGURE 10 , 12B View FIGURE 12 ; whereas it is protruding towards the proximal side, and forming a apophysis in S. hubeiensis ; see Peng et al. 2008: fig. 17); (5) the prolateral proximal branch of the median apophysis has its tip directed towards the proximal side in ventral view ( Figs 10A View FIGURE 10 , 12A View FIGURE 12 ; whereas its tip is directed towards the retrolateral side in S. hubeiensis ; see Peng et al. 2008: fig. 16); (6) the presence of retrolateral tibial apopysis ( Figs 10D View FIGURE 10 , 12D View FIGURE 12 ; whereas absent, might have been overlooked in the original description of S. hubeiensis ; see Peng et al. 2008: fig. 17).
