Etymology.
The specific name refers to the type locality, Shenshan; adjective.
Differential diagnosis.
The new species differs from O. hengshan (Song, 1990) by the bend of the RTA with a strong basal apophysis (Figs 15C, E, F View Figure 15 , 17C View Figure 17 ) (vs. the sub-median part of the RTA with a strong apophysis) and the wider median septum located medially (Fig. 16C, D View Figure 16 ) (vs. narrowed).
Description.
Male (holotype). Habitus as in Fig. 15A View Figure 15 . Total length 3.87, carapace 1.72 long, 1.45 wide. Eye sizes and interdistances: AME 0.08, ALE 0.10, PME 0.08, PLE 0.09; ALE-AME 0.03, AME-AME 0.06, PLE-PME 0.07, PME-PME 0.14, ALE-ALE 0.27, PLE-PLE 0.41, ALE-PLE 0.11, AME-PME 0.10, ALE-PME 0.19. MOA 0.26 long, front width 0.21, back width 0.29. Cervical groove and fovea distinct. Chelicerae (Fig. 15A, B View Figure 15 ) with three promarginal (middle largest, distal smallest) and six retromarginal teeth (distal largest, proximal smallest). Sternum (Fig. 15B View Figure 15 ), posterior pointed. Abdomen (Fig. 15A, B View Figure 15 ) 1.98 long, 1.38 wide, weak dorsal scutum in anterior half. Leg measurements: I 7.21 (1.87, 0.70, 2.24, 1.77, 0.63); II 5.52 (1.52, 0.58, 1.45, 1.38, 0.59); III 4.86 (1.31, 0.54, 1.08, 1.33, 0.60); IV 7.77 (2.09, 0.63, 1.88, 2.15, 1.02). Leg spination: femur I with two dorsal spines, femora II-IV with one dorsal spine each; femora I pv1111 (right), pv11111, II pv111; tibiae I v22222222, II v222222; metatarsi I v2222, II v1222.
Colouration (Fig. 15A, B View Figure 15 ). Carapace yellow, with radial, irregular dark stripes medially and arch-shaped dark stripes around margin. Chelicerae yellow-brown. Endites yellow. Labium yellow-brown. Sternum yellow. Legs yellow, without annulations on tibiae and distal part of femora, patellae, and metatarsi. Abdomen dark brown, with pair of oval and pair of clavate yellowish spots on the posterior dorsal scutum, three light chevron-shaped stripes in posterior part, and yellowish arch-shaped stripe in front of the anal tubercle.
Palp (Figs 15C-F View Figure 15 , 17 View Figure 17 ). Femoral apophysis well developed, width less than half of length. Patella unmodified. Retrolateral tibial apophysis large, slightly less than tibia, finger-like, bending inwards towards base of cymbium, with strong basal apophysis and blunt tip. Sperm duct O-shaped, strongly sclerotised, around base of retrolateral tegular apophysis, distal tegular apophysis and embolus. Retrolateral tegular apophysis clavate, slightly shorter than embolus. Distal tegular apophysis triangular, accompanied by embolus and subterminal apophysis. Embolus, thick, hook-shaped, with broad base and blunt tip.
Female. Habitus as in Fig. 16A, B View Figure 16 . Darker than males. Total length 4.35, carapace 1.91 long, 1.67 wide. Eye sizes and interdistances: AME 0.10, ALE 0.11, PME 0.09, PLE 0.10; ALE-AME 0.02 AME-AME 0.07, PLE-PME 0.08, PME-PME 0.14, ALE-ALE 0.30, PLE-PLE 0.47, ALE-PLE 0.11, AME-PME 0.11, ALE-PME 0.11.

Colouration (Fig. 16A, B View Figure 16 ). Abdomen with pair of irregular yellowish spots behind the first pair of oval spots.
Epigyne (Fig. 16C, D View Figure 16 ). Epigynal plate bow-shaped, antero-medially with pair of concaved copulatory openings, with triangular median septum, copulatory ducts, glandular appendage, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Copulatory ducts broad, slightly sloping, located between copulatory openings and glandular appendages, posteriorly with pair of large, bean-shaped, transparent bursae. Glandular appendages short, partly covered by bursae, located on anterior of connecting tubes. Connecting tubes, twice the length of copulatory ducts, located between glandular appendages and spermathecae. Spermathecae globular, slightly separated.
