Popis: Hersilia aoqin sp. nov. (Figs 1A–B, 2–3, 9) Type material. Holotype ♂ (IZCAS-Ar42706), China, Hainan, Ledong Li Autonomous County, Jianfengling National Park, Mingfeng Valley, 18.7443°N, 109.8427°E, elev. ca 970 m, 26.IV.2009, Guo Tang leg. Paratypes. 1♂ 4♀ (IZCASAr42707–Ar42711), same data as holotype; 1♂ (IZCAS-Ar42712), China, Hainan, Ledong Li Autonomous County, Jianfengling National Park, Wufenqu, 18.7379°N, 108.8669°E, elev. ca 855 m, 13.VII.2010, Guo Zheng leg.; 3♂ 1♀ (IZCASAr42713–Ar42716), China, Hainan, Ledong Li Autonomous County, Jianfengling National Park, Wufenqu, 18.7342°N, 108.8720°E, elev. ca 970 m, 14.VIII.2010, Guo Zheng leg. Diagnosis. The males of the new species resemble H. flagellifera Baehr & Baehr, 1993 (Baehr & Baehr, 1993: figs 31c–d), H. kerekot (Rheims & Brescovit, 2004: figs 11–13), and H. sagada sp. nov. (Figs 5A–C) by the long and strongly coiled embolus and concave median apophysis with a hood and apophysis. They can be distinguished from these species by the embolus coiling 2600° around the MA (Fig. 2) (vs. 2000° in H. flagellifera (Baehr & Baehr, 1993, fig. 31d) and 4100° in H. sagada sp. nov. (Fig. 5)), and the embolus has two embolic apophyses (Fig. 2D) (vs. embolus without apophysis but dense serrations posteriorly in H. flagellifera (Baehr & Baehr, 1993, fig. 31d) and without embolic apophyses in H. kerekot (Rheims & Brescovit, 2004: fig. 12) and H. sagada sp. nov. (Fig. 5)). Females can be distinguished by the copulatory duct with eight turns (Fig. 3B) (vs. five turns in H. flagellifera (Baehr & Baehr, 1993, fig. 31f) and ten turns in H. sagada sp. nov. (Fig. 6B)), and the ratio of the length of the spermathecal duct to the length of the spermathecae is almost 5:1 (Fig. 3B) (vs. 2: 1 in H. flagellifera (Baehr & Baehr, 1993, fig. 31f) and 3: 2 in H. sagada sp. nov. (Fig. 6B)). Description. Male holotype (Figs 1A, 2). Total length 3.86. Carapace 1.60 long, 1.66 wide, brown with inconspicuous dark brown pattern, margin black. Clypeus height 0.16, dark brown anteriorly. Chelicerae yellow-brown, black at base, with eight retromarginal denticles. Eye area dark brown around PME and PLE; eye sizes and interdistances: AME 0.22, ALE 0.11, PME 0.19, PLE 0.16, AME–AME 0.08, AME–ALE 0.09, PME–PME 0.09, PME–PLE 0.07, AME–PME 0.04, ALE–PLE 0.04. Legs yellow-brown, with faint black stripe. Leg measurements: leg I: 18.80 (4.84 + 5.59 + 4.74 +2.92 + 0.71), leg II: 18.78 (4.72 + 5.70 + 4.69 + 3.03 + 0.64), leg III: 5.53 (1.75 + 1.74 + 1.47 + 0.57), leg IV: 15.11 (4.08 + 4.40 + 4.27 + 2.36 + 0.60). Leg formula: 1243. Abdomen 2.22 long, 2.02 wide, brownish cream coloured with dark brown pattern; lancetshaped cardiac impression; with four pairs of orange-brown muscle impressions, second pair largest; laterally brown. bS 0.61, tS 2.96. Palp (Fig. 2). Tibia almost as long as patella, with a hood prolaterally; cymbium long, almost two times longer than wide, five strong apical spines. Tegulum obscured by embolus coils; embolus originating at seven o’clock, coiling around median apophysis; median apophysis pointed distally, with a tegular projection. Female paratype (Figs 1B, 3). Colouration and pattern as in males, but white arrow pattern on cephalic region and general colouration is lighter than in males. Total length 3.08. Carapace 1.73 long, 1.70 wide. Clypeus height 0.24. Chelicerae with 8 retromarginal denticles. Eye sizes and interdistances: AME 0.24, ALE 0.13, PME 0.25, PLE 0.17, AME–AME 0.11, AME–ALE 0.16, PME–PME 0.09, PME–PLE 0.16, AME–PME 0.08, ALE–PLE 0.04. Leg measurements: leg I: 13.00 (3.46 + 3.77 + 3.02 +2.22 + 0.53), leg II: 13.65 (3.49 + 4.10 + 3.10 + 2.41 + 0.55), leg III: 4.52 (1.42 + 1.44 + 1.15 + 0.51), leg IV: 11.01 (3.02 + 3.38 + 2.82 + 1.79 + 0.54). Leg formula: 2143. Abdomen 2.73 long, 3.08 wide. bS 0.66, tS 3.35. Epigyne (Fig. 3) with epigynal teeth on posterior margin of lateral lobes. Median septum wide, two round atria visibly separated; copulatory opening anterior in atria. Median part of copulatory duct translucent; ducts with wrinkles where they make two turns. One pair of spermathecae, spermathecae oval, spermathecal duct consistently thin. Fertilization ducts sickleshaped. Etymology. The species is named after Aoqin, the vermillion dragon master of the fire element and king of the South China Sea; noun. Distribution. Known only from the type locality.
