Figs 3, 110–119

Type material. Holotype: ♂ (MHBU-ARA-00023545), CHINA: Yunnan Province, Jinping County, Jinping Fenshuiling National Nature Reserve, 22.8666°N, 103.2167°E, 1847 m elev., 24 July 2006, leg. Z. Yang & Y. Wang. Paratypes: 2♂ 4♀ (MHBU-ARA-00023543~MHBU-ARA-00023544), same data as holotype .

Etymology. The specific epithet is from the type locality; noun in apposition.

Diagnosis. It resembles O. shuyuani sp. nov. in the shape of embolus, but can be distinguished by the ridge near embolic base that is pointing upwards (Figs 117, 120; vs. the ridge pointing downwards in O. shuyuani sp. nov.). Females can be distinguished from O. shuyuani sp. nov. by the subtriangular starting part of copulatory ducts and the longer accessory glands.

Description. Male. Habitus of as shown in Fig. 110. Measurements of holotype: carapace length 2.19; abdomen length 2.38; measurements of eyes: AME 0.40, ALE 0.25, PME 0.06, PLE 0.20; measurements of legs: I 3.76 (1.16, 0.75, 0.80, 0.60, 0.45), II 3.18 (1.01, 0.59, 0.62, 0.52, 0.44), III 3.51 (1.13, 0.55, 0.71, 0.66, 0.46), IV 4.00 (1.22, 0.61, 0.92, 0.76, 0.49); leg formula 1432. Dorsal body dark, cephalon covered by relatively dense pale setae; dorsal abdomen covered by sparse pale setae. Legs light-colored, melanic area indistinct.

Palp (Figs 112–114): palpal bulb swollen, lobe-like protrusion of tegulum short and stout; embolus relatively slender, curved medially in ventral view, with one ridge near embolic base pointing upwards (Fig. 120); apophysis of embolic disc sharp (Fig. 118); RTA wide at basal and median part, narrow at distal part; pro-ventral hump of tibia pointing ventrally, semicircular in prolateral view (Figs 113, 117).

Female. Habitus as shown in Fig. 111. Measurements of paratype: carapace length 2.47; abdomen length 3.20; measurements of eyes: AME 0.44, ALE 0.25, PME 0.04, PLE 0.22; measurements of legs: I 3.79 (1.21, 0.78, 0.78, 0.56, 0.46), II 3.43 (1.13, 0.63, 0.67, 0.52, 0.48), III 3.72 (1.18, 0.57, 0.75, 0.72, 0.50), IV 4.45 (1.39, 0.65, 1.02, 0.87, 0.52); leg formula 4132. Coloration like male but legs I–II slightly dark, setae on dorsal body sparse .

Epigynum (Fig. 115): atria oval, close to each other and far away from genital furrow. Vulva (Fig. 116): starting part of copulatory ducts enlarged and partly fused to spermathecae; spermathecae dark red, strongly sclerotized.

Natural history. All specimens were collected from the thick moss on large rocks, and they built silk tubes under the moss.

Distribution. China (Yunnan).
