Etymology. The specific epithet is taken from its similarity to O. liupan Hu & Zhang, 2011; noun in apposition.
Diagnosis. The new species is closely related and very similar to O. liupan (Hu & Zhang 2011: 60, figs 1 – 7), but differs from the latter by the wide separation between the tip of the RTA and the base of the cymbium in the retrolateral view, and the stronger and less curved tegular process of its male palp (Figs 5 A–C, 6C–E); females are distinguished by the narrow median plate, the small bursae that do not overlap and are much longer than wide, and the stronger, inwardly curved spermathecae of the epigyne (Figs 5 D–E, 6F–G).
Description. Male. Total length 3.31–3.97. Holotype (Fig. 6 A) total length 3.84. Prosoma 1.82 long, 1.52 wide; opisthosoma 1.99 long, 1.29 wide. Dorsum of prosoma black brown. Eye sizes and interdistances: AME 0.10, ALE 0.11, PME 0.09, PLE 0.10; AME–AME 0.07, AME–ALE 0.02, PME–PME 0.12, PME–PLE 0.07, ALE–PLE 0.10. MOA 0.31 long, front width 0.25, back width 0.31. Clypeus height 0.17. Chelicerae stout, yellow brown with three promarginal and six retromarginal teeth. Gnathocoxae yellow brown, longer than wide. Labium yellow brown, as long as wide. Sternum yellow brown, heart-shaped with sparse brown hairs. Legs yellow brown, femur with one dorsal spine. Femur I with four prolateral spines; tibia I with seven pairs of ventral spines; metatarsus I with four pairs of ventral spines. Femur II with three prolateral spines; tibia II with six pairs of ventral spines; metatarsus II with four pairs of ventral spines. Leg measurements: I 7.21 (1.84, 2.72, 1.72, 0.93); II 5.92 (1.54, 2.12, 1.35, 0.91); III 4.98 (1.46, 1.36, 1.40, 0.76); IV 8.10 (2.20, 2.55, 2.29, 1.06). Leg formula: 4123. Opisthosoma oval. Dorsum yellow brown with black brown markings and seven bright chevron-like markings. Venter yellow brown.
Male palp (Figs 5 A–C, 6C–E). Femoral ventral apophysis present. RTA with wide base extending dorsally, tip finger-shaped. Embolus wide and hook-like. Sperm duct sclerotized. Tegular process originating anteroretrolaterally, almost same width as embolus in retrolateral view. Tegulum widest in middle part, its posterior margin almost reaching ventral apex of tibia retrolaterally.
Female total length 4.02–4.30. One paratype (from Jiangkou County, Taiping Town, Kaiwen Village, Fig. 6 B) total length: 4.13. Prosoma 1.93 long, 1.65 wide; opisthosoma 2.22 long, 1.53 wide. Eye sizes and interdistances: AME 0.09, ALE 0.09, PME 0.09, PLE 0.10; AME–AME 0.06, AME–ALE 0.03, PME–PME 0.14, PME–PLE 0.09, ALE–PLE 0.12. MOA 0.31 long, front width 0.24, back width 0.34. Clypeus height 0.16. Leg measurements: I 7.35 (1.74, 2.89, 1.84, 0.88); II 6.08 (1.58, 2.15, 1.46, 0.89); III 4.95 (1.40, 1.56, 1.29, 0.70); IV 7.82 (2.12, 2.49, 2.23, 0.98). Leg formula: 4123. Other characters as for male holotype.
Epigyne (one paratype, from Songtao County, Wuluo Town, Maxi’ao, Figs 5 D–E, 6F–G). Median plate broad anteriorly and converged posteriorly, with arc-shaped lateral margin. Copulatory openings small, oval, located near anterior end of lateral margin of median plate, widely separated. Copulatory ducts with pair of transparent bursae, separated from each other. Spermathecae club-shaped. Fertilization ducts arising anteriorly.
Distribution. Known only from the type locality, Guizhou, China (Fig. 13).
