(AṘ山Þffifl) Figs 10C–D , 13 , 14 Type material. Holotype ♂ : CHINA : Hunan Province : Yongzhou City , Dongan County , Damiaokou Town , Shunshan Park ( 26°24′58.684″N , 111°02′08.473″E , 694 m elev.), 8 Oct. 2015 , leg. Chi Jin. Paratypes : 2♂ 8♀ , same data as holotype . Etymology. The species name is derived from the type locality; noun in apposition. Diagnosis. This new species resembles O. hamatus ( Wang, Zhang & Zhang, 2012 ) by having a similarly shaped DTA, short sperm duct, embolus and small spermathecae (see Figs 13A–B , 14A–B and fig. 9E–F in Wang et al . 2012 ), but the male can be distinguished by the wide, dagger-shaped RTA, without a hook at the apex in retrolateral view ( vs thin, with a small hook at the tip of the RTA, compare Figs 13B , 14B with figs 8C, 9F in Wang et al. 2012 ), and the short and thin conductor ( vs wide and long conductor, compare Figs 13C , 14C with figs 8B, 9G in Wang et al. 2012 ). Females can be distinguished by the short and wide median septum ( vs narrow, compare Fig. 14E with fig. 8D in Wang et al. 2012 ) and the two horn-shaped copulatory openings ( vs coalescent copulatory openings, compare Fig. 14E–F with fig. 8D–E in Wang et al . 2012 ).

Chelicerae with three promarginal and seven retromarginal teeth. Carapace yellow, with black and irregular grid-like line radiating from fovea. Abdomen gray, with small dorsal scutum anteriorly, two triangular black spots beside scutum, and four black transverse stripes posteriorly ( Fig. 10C ). Palp as in Figs 13A–D , 14A–D . FA in distal half of femur. RTA small and short, dagger-shaped in retrolateral view, with aciculate tip ( Figs 13B , 14B ). DTA thin and long, curved, tip curved towards prolateral side of cymbium ( Figs 13D , 14D ). Tegulum oval, posterior edge round, with small TA distally ( Fig. 14C ). Sperm duct short, located in distal 1/4 of tegulum. Embolus thin, transverse, with wide base and pointed tip. Conductor short and thin, vertical. Female: total length 2.40–2.68 (n=8). One paratype ( Fig. 10D ): total length 2.60, carapace 1.28 long, 1.07 wide (CW); abdomen 1.32 long, 0.98 wide.

Eye area 0.38 wide (EAW), cephalic region 0. 60 wide (CRW), EAW/CRW 0.63; CRW/CW 0.56. MOA 0.15 long, anterior width 0.15, posterior width 0.16. Clypeal height 0.09 ( CH ), CH / AME 1.29 . Other characters as for male, except heavier color and larger body size . Epigyne as in Figs 13E–F , 14E–F . Median septum wide and short ( Figs 13E , 14E ). Copulatory openings hornshaped, located at anterior of septum, separated by about two times diameter of spermathecae ( Fig. 14E–F ). Copulatory ducts thick, transverse, ends curved upwards, connecting with bursa. Bursa large and transparent, nearly rectangular. Connecting tube thin, nearly straight, extending to posterior of spermathecae in ventral view ( Fig. 14E ). Spermathecae oval, small, separated from each other about two times diameter of spermathecae. Fertilization ducts short, located at anterior of spermathecae. FIGURE 14.
