Females can be distinguished by the short and wide median septum ( vsnarrow, compare Fig. 14Ewith fig. 8D in Wang et al.2012) and the two horn-shaped copulatory openings ( vscoalescent copulatory openings, compare Fig. 14E–Fwith fig. 8D–E in Wang et al. 2012).   Description.Male: total length 2.21–2.31 (n=3). Holotype( Fig. 10C): total length 2.21, carapace 1.19 long, 1.01 wide (CW); abdomen 1.02 long, 0.75 wide. Eye sizes and interdistances: AME 0.06, ALE 0.09, PME 0.06, PLE 0.08; PME–PME 0.06, AME–ALE 0.01, ALE–ALE 0.16, PME–PME 0.07, PME–PLE 0.05, PLE–PLE 0.26, ALE–PLE 0.04. Eye area 0.37 wide (EAW), cephalic region 0.56 wide (CRW), EAW/CRW 0.66. CRW/CW 0.55. MOA 0.16 long, anterior width 0.14, posterior width 0.16. Clypeal height 0.11 ( CH), CH/AME 1.83. 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. Eyesizes and interdistances: AME0.07, ALE0.08, PME0.04, PLE0.08; AME– AME0.04, AME– ALE0.01, ALE– ALE0.17, PME– PME0.07, PME– PLE0.06, PLE– PLE0.28, ALE– PLE0.05. Eye area0.38 wide (EAW), cephalic region 0. 60 wide (CRW), EAW/CRW 0.63; CRW/CW 0.56. MOA0.15 long, anterior width 0.15, posterior width 0.16. Clypealheight 0.09 ( CH), CH/ AME 1.29. Othercharacters 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.  Otacilia shunhuangshan  sp. nov.: A. Male left palp, prolateral view; B. same, retrolateral view; C.
