Type material.
Holotype: ♂, China, Jiangxi Province, Ji’an City, Xingan County, Zaoshi Village, 27°46'15.63"N, 115°39'38.10"E, 589 m, 7 October 2019, leg. Ke-ke Liu et al. Paratypes: 4 ♂, 1 ♀, 4 juveniles, with same data as holotype.
Etymology.
The specific name is derived from the type locality, Zaoshi village, which is one of the famous traditional villages; adjective.
Diagnosis.
The males of the new species are similar to O. yusishanica sp. nov. described above in having a finger-like retrolateral tibial apophysis (Fig. 15C-F View Figure 15 ), but can be separated from it by the arc-shaped embolic base (Figs 18D View Figure 18 , 19A, B View Figure 19 ) (vs. triangular) and the retrolateral tegular apophysis accompanied by the embolus (Figs 18D View Figure 18 , 19A, B View Figure 19 ) (vs. separated).The females resemble O. yusishanica sp. nov. by having a broad median septum and the thin connecting tubes (Fig. 17C, D View Figure 17 ), but can be separated from it by the saddle-shaped copulatory openings (Fig. 20C View Figure 20 ) (vs. oval) and the spermathecae separated by approximately 1/3 of the median septum width (Fig. 20D View Figure 20 ) (vs. 2/3).

Male (holotype). Habitus as in Fig. 18A, B View Figure 18 . Total length 2.90, carapace 1.21 long, width 1.03 wide. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.05, PLE 0.06, AME-AME 0.07, AME-ALE 0.03, PME-PME 0.12, PME-PLE 0.05, AME-PME 0.10, AME-PLE 0.12, ALE-ALE 0.21, PLE-PLE 0.31, ALE-PLE 0.1. MOA 0.20 long, frontal width 0.15, posterior width 0.19. Chelicerae (Fig. 18A, B View Figure 18 ) with three promarginal (proximal largest, second smallest) and five retromarginal teeth (distal largest, second smallest). Sternum (Fig. 18B View Figure 18 ) longer than wide. Pedicel 0.21 long. Abdomen (Fig. 18A, B View Figure 18 ) 1.51 long, 0.86 wide. Leg measurements: I 4.92 (1.24, 0.41, 1.50, 1.06, 0.71); II 3.86 (1.08, 0.45, 1.04, 0.99, 0.30); III 3.11 (0.84, 0.31, 0.69, 0.83, 0.44); IV 5.75 (1.64, 0.43, 1.37, 1.59, 0.72). Leg spination (Fig. 18A, B View Figure 18 ): femora I-IV with one dorsal spine each; femora I pv1111, II pv11; tibiae I v2222222, II v2222222; metatarsi I v2222, II v2222.
Colouration (Fig. 18A, B View Figure 18 ). Carapace yellow, medially with broad dark brown mottled markings. Fovea distinct, black. Chelicerae, endites, labium and sternum yellow-brown. Legs yellow, without dark annulations. Abdomen dark brown, with pair of round and oval pale spots located at posterior of dorsal scutum and three light chevron-shaped stripes in posterior part, and one yellowish transversal stripe in front of anal tubercle.
Palp (Figs 18C-F View Figure 18 , 19 View Figure 19 ). Femoral apophysis well-developed, width more than half of its length. Patella unmodified. Retrolateral tibial apophysis large, longer than tibia, sword-like in ventral view, bending inward to base of cymbium, medial part widened and slightly curved, with strong spine-like tip. Sperm duct U-shaped, strongly sclerotized, around base of subterminal apophysis, distal tegular apophysis and embolus. Retrolateral tegular apophysis straight, broad, as long as embolus, anteriorly widened. Distal tegular apophysis membranous, fan-shaped, extending to median bulb. Embolus thick, hook-shaped, with broad base and blunt tip. Embolus relatively long, thick spine-like, with broad base and blunt apex.
Female (paratype). Habitus as in Fig. 20A, B View Figure 20 . Lighter than males. Total length 3.07, carapace 1.36 long, 1.19 wide. Eye sizes and interdistances: AME 0.09, ALE 0.09, PME 0.08, PLE 0.08, AME-AME 0.04, AME-ALE 0.01, PME-PME 0.09, PME-PLE 0.06, AME-PME 0.06, AME-PLE 0.14, ALE-ALE 0.21, PLE-PLE 0.32, ALE-PLE 0.09. MOA 0.24 long, frontal width 0.20, posterior width 0.24. Chelicerae (Fig. 20A, B View Figure 20 ) with three promarginal (proximal largest, distal smallest) and six retromarginal teeth (distal largest, second smallest). Pedicel 0.17 long. Abdomen (Fig. 19A, B View Figure 19 ) 1.47 long, 0.97 wide. Leg measurements (Fig. 20A View Figure 20 ): I 5.63 (1.47, 0.51, 1.73, 1.25, 0.67); II 4.50 (1.20, 0.46, 1.25, 1.02, 0.57); III 3.84 (1.02, 0.43, 0.87, 0.93, 0.59); IV 6.14 (1.69, 0.55, 1.44, 1.71, 0.75). Leg spination (Fig. 20A, B View Figure 20 ): femora I pv1111, II pv111; tibiae I v22222222, II v2222222; metatarsi I v2222, II v222.
Epigyne (Fig. 20C, D View Figure 20 ). Epigynal plate mask-shaped, anterior margin slightly sclerotized, transverse, medially with pair of touching saddle-shaped copulatory openings, posteriorly with sub-trapezoidal median septum. Copulatory ducts, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Copulatory ducts between copulatory openings and glandular appendages, sloping laterally, proper broad, posteriorly with pair of large, oval, transparent bursae. Glandular appendages short, near the base of bursae. Connecting tubes slightly shorter than copulatory ducts, slightly curved backwards. Spermathecae slightly expanded, directed medially, separated by approximately 1/3 of median septum width. Fertilization ducts short, with semi-ovoid base, directed forward.
