Type material: Holotype male (IZCAS Ar 19315), China: Hainan, Baisha, Yinggeling, Yinggezui Protection Station, 728 m a.s.l., 19°02.933´N, 109°33.654´E, 22 August 2010, leg. G. Zheng; 1 female paratype (IZCAS Ar 19316), same data as holotype, 693 m a.s.l., 19°03.049´N, 109°33.751´E, 25 August 2010, leg. G. Zheng; 1 female paratype (IZCAS Ar 19317), same data as holotype, 678 m a.s.l., 19°03.047´N, 109°33.782´E, 21 August 2010, leg. G. Zheng.
Etymology: The specific name is an adjective and refers to the shape of the female genitalia.
Diagnosis: The new species is most similar to O. sedotmikha Saaristo, 2007, but can be distinguished by the enlarged tibia of the male palp, the shape of the male endites and the female genitalia.
Description: Male. Total length 1.18, carapace length 0.55, carapace width 0.51, abdomen length 0.62. Habitus as in Figs 1G, H. Color in alcohol: Carapace yellow, legs and palp pale yellow. Cephalothorax: Carapace oval, surface smooth, with net-shaped pattern, pars cephalica slightly elevated in lateral view, with rounded posterolateral corners. Clypeus (Fig. 3 E) similar to O. aureola sp. nov., medially black brown; ALE separated from edge of carapace by their diameter or more; setae present, needle-like. Eyes similar to O. aureola sp. nov. Sternum (Fig. 2D) longer than wide, with dark brown patches, without radial furrows between coxae, surface smooth; setae sparse, needle-like, evenly scattered, without hair tufts. Mouthparts: Chelicerae straight, anterior face unmodified; labium elongated hexagon, not fused to sternum, anterior margin not indented at middle; endites (Figs 2D, 9A) distally not excavated, serrula absent, anterolaterolly with 2–3 strong setae. Abdomen ovoid, with gray net-like pattern; pedicel tube short, unmodified, scuto-pedicel region unmodified. Legs without color pattern; femur IV thickened, much larger than femora I–III. Male genitalia (Figs 9 B–D): Tibia of palp enlarged, cymbium small. Bulbus globose, The sclerotized seminal duct slightly curved and partly visible through the cuticle of the palpal bulb. Embolus band shaped, short.
Female. Total length 1.21, carapace length 0.62, carapace width 0.44, abdomen length 0.67. As in male except as noted. Endites with serrula, without strong setae. Female genitalia: Ventral view (Figs 5 F, 9E): without special external features, the internal genital structures shining through the integument, including a vague arch (Va in Fig. 9 E). Dorsal view (Figs 5 G, 9F): Medially a tube-like sclerite; ventral of the sclerite a thin stick-shaped sclerite that is connected to the cuticle; posterior to the sclerite a semicircular sclerite (Ssc in Fig. 9 F).
Distribution: Known only from Hainan Island.
