Figures 7−9

Type material: Holotype: female (ASM-JGSU) from Jingzhu Mountain , Jingzhushan village , Ciping Town , Jinggangshan County Level City , Ji’an City, Jiangxi Province, China (26.494°N, 114.074°E, alt. 1173 m), 13.VIII.2016, K. Liu, Y. Zhao & Q. Danzeng . Paratype: 1 female (ASM-JGSU), same data as holotype .

Etymology. The species name is a patronym in honor of Professor Changmin Yin, one of the pioneers in spider taxonomy in China.

Diagnosis. Females of this species resemble those of S. lushanensis Xie & Yin, 1990 in having very short Sshaped sclerotized loops in the copulatory duct (see Xie & Yin 1990: figs 14−15), but can be distinguished by: spermathecae longitudinally elongated, anterior parts appressed against each other (horizontally elongated, anterior parts separated away from each other in S. lushanensis ) ( Figs 7C–D , 8A–B ).

Description. Female ( Figs 7 , 8 ). Total length 4.71, CL 1.89, CW 1.33, AL 2.66, AW 1.34. EL 1.18; AERW 1.25, AMEW 0.79, PERW 1.35, PMEW 1.09. Carapace reddish-brown ( Fig. 7A ), with well-marked fovea. Eye field square ( Fig. 7A ), covered with short yellow hairs; anterior eye row with 2−3 rows of yellow-brown hairs in dorsal view. Fovea round, hollowed ( Fig. 7A ). Chelicerae reddish-brown ( Fig. 7B ). Endites yellowish-brown ( Fig. 7B ), longer than wide, with short, abundant hairs on anterior margin. Labium ( Fig. 7B ), yellow, with a 12−14 strong setae on the anterior margin. Sternum ( Fig. 7B ) yellow, with abundant hairs on the surface. Measurements of legs: I 4.65 [1.43, 1.09, 1.22, 0.54, 0.37]; II 2.98 [0.96, 0.43, 0.68, 0.58, 0.33]; III 3.26 [0.98, 0.38, 0.77, 0.78, 0.35]; 4.42 [1.22, 0.57, 1.17, 1.05, 0.41]. Leg formula: I, IV, III, II. Femur I width 0.41; femur II width 0.24. Leg spination: I: Tibia p v 2-2 -1, r v 2-2 -1; Metatarsus p v 1-1 -0, r v 1-1 -0. Abdomen ( Figs 7A, B ), the second pair of patches clearly located on the anterior part in dorsal view, all the herringbone strips slender. Spinnerets dark yellow-brown ( Fig. 9B ), with abundant brown hairs. Epigyne ( Figs 7C–D , 8A–B ) spade-shaped, copulatory opening bilaterally located; with obvious S-shape copulatory duct, short glandular ducts, oval spermathecae, and long fertilization ducts.

Male: Unknown.

Distribution. Known only from Jiangxi province, China ( Fig. 9 ).
