Etymology.
The specific name refers to the type locality, Bijiashan; adjective.
Differential diagnosis.
The new species differs from O. fabiformis Liu, Xu, Xiao, Yin & Peng, 2019 and O. hippocampa Jin, Fu, Yin & Zhang, 2016 by the short hook-shaped embolus (Figs 9D View Figure 9 , 11A, B View Figure 11 ) (vs. spine-like in O. fabiformis and O. hippocampa ), and the C-shaped spermathecae (Fig. 10D View Figure 10 ) (vs. peanut-like in O. fabiformis and globular in O. hippocampa ).

Male (holotype). Habitus as in Fig. 9A, B View Figure 9 . Total length 2.56, carapace 1.24 long, 1.07 wide.

MOA 0.21 long, front width 0.15, back width 0.22. Chelicerae (Fig. 9B View Figure 9 ) three promarginal (proximal largest, distal smallest) and two retromarginal teeth (distal larger Sternum, posteriorly pointed. Abdomen (Fig. 9A, B View Figure 9 ), 1.42 long, 0.97 wide. Leg measurements: I 4.64 (1.21, 0.50, 1.35, 1.08, 0.50); II 4.00 (1.10, 0.48, 1.05, 0.95, 0.42); III 3.49 (0.90, 0.41, 0.74, 0.93, 0.51); IV 4.95 (1.30, 0.46, 1.10, 1.38, 0.71). Leg spination: femur I with two dorsal spines, femora II-IV with one dorsal spine each; femora I pv111, II pv11; tibiae I v2222222, II v222222; metatarsi I v2222, II v1222.
Colouration (Fig. 9A, B View Figure 9 ). Carapace yellow, with radial, irregular dark stripes submarginally and arc-shaped dark stripes around margin. Chelicerae yellow brown. Endites, labium and sternum yellow. Legs yellow, with distinct annulations on tibiae and distal part of femora, patellae and metatarsi. Abdomen yellowish, with two large C-shaped stripes on the two sides of dorsal scutum and four light chevron-shaped stripes in submedial part, and single yellowish transverse stripe posteriorly.
Palp (Figs 9C-F View Figure 9 , 11 View Figure 11 ). Femoral apophysis well-developed, width longer than half of length. Patella unmodified. Retrolateral tibial apophysis large, longer than tibia, horn-shaped, with a sharp apex in retrolateral view. Dorsal tibial apophysis large, slightly shorter than tibia, with sharp narrowed sub-medial part and a spine-like apex in dorsal view. Sperm duct strongly sclerotised, hook-shaped in ventral view, anterior part thick, gradually narrowed in posterior part. Retrolateral tegular apophysis extruding laterally, in front of anterior part of sperm duct. Embolus short and hook-shaped.
Female. Habitus as in Fig. 10A, B View Figure 10 . Lighter than males. Total length 2.62, carapace length 1.26, width 1.10. Eye diameters: AME 0.06, ALE 0.08, PME 0.07, PLE 0.08; interdistances: ALE-AME 0.01, AME-AME 0.03, PLE-PME 0.05, PME-PME 0.07, ALE-ALE 0.14, PLE-PLE 0.31, ALE-PLE 0.08, AME-PME 0.08, ALE-PME 0.09.

Colouration (Fig. 10A, B View Figure 10 ). Legs without distinct annulations on femora, patellae, tibiae and metatarsi. Abdomen, antero-medially with longitudinal grey-brown stripe connecting with paired yellowish spots in dorsal view.
Epigyne (Fig. 10C, D View Figure 10 ). Epigynal plate snake-like, with a narrowed median septum, copulatory ducts, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Anteromedially with small round copulatory openings. Copulatory ducts short, proper broad, almost parallel, medially located between copulatory openings and glandular appendage. Connecting tubes short, C-shaped, shorter than connecting tubes. Spermathecae, C-shaped. Fertilisation ducts extending anteriorly.
