Type material. Holotype ♂ (CQCK-18-02): CHINA: Chongqing City, Chengkou County, Longtian Town , Wuli village , hillside behind primary school (32°03.726′N, 108°40.351′E, 1206 m), 16 Mar. 2018, leg. Zhisheng Zhang.

Paratypes: 3♂ 7♀, with same data as holotype; CHINA : 2♀ (CQCK-18-03), Chongqing City, Chengkou County, Longtian Town , Wuli village (32°04.269′N, 108°39.914′E, 1286 m), 16 Mar. 2018, leg. Luyu Wang.

Etymology. The species name is derived from the type locality; noun in apposition.

Diagnosis. The male of this new species resembles O. longituba Wang, Zhang & Zhang, 2012 , but can be distinguished by the wide, blunt tip of the RTA in dorsolateral view (vs rectangular) and the triangular conductor (vs oval) in the male (compare Fig. 4E–F with fig. 5E–G in Wang et al. 2012). Females can be separated from O. longituba by the long and more curved copulatory ducts (vs short and simply curved) and the copulatory openings well separated from each other (vs close together) (compare Fig. 4G–H with fig. 5H–I in Wang et al. 2012).

Carapace brown, higher at central area; with petal-shaped pattern directed towards legs I–IV either side of fovea. Cervical groove indistinct; fovea dark red. Eye sizes and interdistances: AME 0.08, ALE 0.08, PME 0.06, PLE 0.10; AME–AME 0.04, AME–ALE 0.02, ALE–ALE 0.24, PME–PME 0.15, PME– PLE 0.08; PLE–PLE 0.41, ALE–PLE 0.11.

Abdomen oval, with small yellow dorsal scutum anteriorly, several black and gray transverse stripes posteriorly.

Palp as in Fig. 4C–F . RTA flake-shaped, base wide, narrowed medially, and proximally inflated, nearly round ( Fig. 4C ), with blunt tip. Tibia with sclerotized rounded prolateral apophysis ( Fig. 4D ). Bulb pyriform, sperm duct wide, strongly sclerotized; tegular apophysis small, located at distal end of tegulum; embolus long and thin, directed distally at base, curving sharply, distal section slanting retrodistally; conductor membranous, triangular in ventral view.

Female. Total length 3.38–3.93 (n=9). One paratype: total length 3.53; carapace 1.42 long, 1.24 wide; abdomen 2.11 long, 1.80 wide.

Clypeal height 0.12. Legs faint yellow. Measurements of legs: I 5.26 (1.40, 0.54, 1.57, 1.20, 0.55), II 4.37 (1.16, 0.46, 1.14, 0.99, 0.62), III 3.79 (0.98, 0.43, 0.82, 1.01, 0.55), IV 5.77 (1.55, 0.48, 1.30, 1.64, 0.82).

Abdomen gray, with six oblique black chevron stripes posteriorly. Other characters as in male, except darker body color and broader abdomen.

Epigyne as in Fig. 4G–H . Epigynal plate poorly sclerotized, slightly transparent. Copulatory openings small, copulatory ducts laterally placed, short and thick; glandular appendages thick, beneath copulatory duct; bursae large, transparent, balloon-shaped; spermathecae oval, small, positioned mesally; fertilization ducts short, located at anterior of spermathecae.

Distribution. China (Chongqing City) ( Fig. 8).
