Figs 9 , 10 Type material. Holotype ♂ (IZCAS-Ar44510), China: Hainan: Qiongzhong County, Limushan National Nature Reserve, Diaodengling Waterfall ( 19°10.87′N , 109°45.32′E , ca. 940 m), 5.v.2011, Y.Y. Zhou leg. Paratypes 1♂2♀ (IZCAS-Ar44511-44513), same data as holotype; 2♀ (IZCAS-Ar44514-44515), Limushan National Nature Reserve, Direction of Shuiba ( 19°10.87′N , 109°45.32′E , ca. 960 m), 5.v.2011, Y.Y. Zhou leg.; 1♂2♀ (IZCAS-Ar44516-44518), Wuzhishan City, Wuzhishan National Nature Reserve, Shanye Hotel ( 18°54.42′N , 109°40.65′E , ca. 1590 m), 26.iv.2011, Y.Y. Zhou leg. Etymology. The specific name is after Mr. Bai Li (701-762), a famous ancient Chinese poet, who was crowned as Poetry Immortal; noun (name) in genitive case. Diagnosis. The male of Logunattus libaii sp. nov. resembles that of L. dufui sp. nov. in general shape of palp, but it can be easily distinguished by the embolus, which is curved medially, and without proximal apophysis in ventral view (Fig. 9B ), vs. straight and with proximal apophysis in L. dufui (Fig. 8B ). The female of this new species resembles that of Spiralembolus yinggeling sp. nov. in having similar epigyne, but it can be easily distinguished by the presence of median septum, and accessory glands of copulatory ducts (Fig. 10A, B ), vs. absent in S. yinggeling (Fig. 20A, B ). Description. Male (Figs 9 , 10C, D, F, G ). Total length 3.45. Carapace 1.83 long, 1.37 wide. Abdomen 1.53 long, 1.15 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.38, ALE 0.26, PLE 0.20, AERW 1.32, PERW 1.20, EFL 0.79. Legs: I 4.08 (1.15, 0.68, 1.05, 0.75, 0.45), II 3.16 (0.93, 0.58, 0.70, 0.55, 0.40), III 3.77 (1.15, 0.58, 0.86, 0.78, 0.40), IV 3.79 (1.10, 0.53, 0.83, 0.95, 0.38). Carapace red-brown to dark brown, covered with dense setae; fovea dark, longitudinal, bar-shaped. Chelicerae red-brown to dark brown, each with two promarginal teeth and one retromarginal tooth. Endites dark yellow, with pale distal-inner margins bearing dense brown setae. Labium darker than endites. Sternum coloured as endites, slightly longer than wide, with straight anterior margin, widest medially. Legs yellow to dark brown, with three and two pairs of ventral spines on tibiae and metatarsi I and II, respectively. Abdomen oval, dorsum with two pairs of anterior muscle depressions, indistinct brown or dark brown stripes, and big, irregular pale marking posteriorly, covered by anteromedian scutum; venter pale, with pair of longitudinal, dotted lines. Palp (Fig. 9A-C ). Tibia short, with ventro-prolateral bump, covered with white dorsal setae; RTA dagger-axe-shaped, almost 1.5 times longer than tibia, with pointed tip; cymbium ~ 1.8 x longer than wide in ventral view, covered with dorsal white setae at proximal half; bulb elongate-oval, with blunt posterior lobe extending postero-retrolaterally; embolus originates from the antero-prolateral portion of bulb, forming a disc at base, curved towards prolateral side medially and with rather pointed tip directed towards ~ 10:30 o'clock position. Figure 10. Logunattus libaii sp. nov., male holotype and female paratype A epigyne, ventral B vulva, dorsal C holotype habitus, dorsal D ditto, ventral E female paratype habitus, dorsal F holotype carapace, frontal G holotype chelicera, posterior. Scale bars: 0.1 mm ( A, B, G ); 0.5 mm ( C-F ). Female (Fig. 10A, B, E ). Total length 4.02. Carapace 1.87 long, 1.39 wide. Abdomen 2.18 long, 1.64 wide. Clypeus 0.09 high. Eye sizes and inter-distances: AME 0.40, ALE 0.27, PLE 0.20, AERW 1.26, PERW 1.15, EFL 0.84. Legs: I 3.59 (1.05, 0.63, 0.88, 0.60, 0.43), II 3.14 (0.98, 0.53, 0.70, 0.50, 0.43), III 3.89 (1.23, 0.60, 0.85, 0.78, 0.43), IV 3.99 (1.18, 0.53, 0.88, 0.95, 0.45). Habitus (Fig. 10E ) similar to that of male except paler, and without scutum on the dorsum of abdomen. Epigyne (Fig. 10A, B ). Wider than long, with pair of shallow atria anteromedially; copulatory openings almost half round, open towards downward, separated by the slightly raised median septum; copulatory ducts curved medially, and touched distally, with sub-triangular proximal accessory glands extending antero-prolaterally; spermathecae oval; fertilization ducts lamellar, extending transversely. Distribution. Known only from the type locality in Hainan Island, China.
