description: <i>Leptonetela sexdentata</i> sp. nov. Figs 53–56, 72 Type material. <b>Holotype:</b> male (IZCAS), Huanglong Cave, Wuling Reserve [29°37´N, 110°49´E], Zhangjiajie, Hunan, China, 30 October 2005, S. Li leg. <b>Paratypes:</b> 7 males and 8 females, same data as holotype. <b>Etymology.</b> The specific name is from Latin words, “sex” and “dentatus”, meaning “six” and “toothed”, and refers to the six toothed median apophysis in the male; adjective. <b>Diagnosis.</b> This new species is similar to <i>L. quinquespinata</i> (Chen &amp; Zhu, 2008), but can be distinguished by the presence of six eyes (Figs 53A, 54A); the eight promarginal cheliceral teeth (Fig. 56A); five spines on the retrolateral surface of palpal tibia, the basal one thick, conspicuous, with insertion of a small spine apically (Figs 53D, 55A–B); the palm-shaped median apophysis; and the presence of six small teeth on the distal part of median apophysis in the male (Fig. 53B). <b>Description. Male (holotype):</b> total length 1.82 (Fig. 53A). Prosoma 0.92 long, 0.78 wide. Opisthosoma 1.06 long, 0.84 wide. Prosoma yellow, with a pair of setae retrolateral of PLE. Median groove needle-shaped, pale brown. Cervical grooves and radial furrows indistinct. Clypeus 0.16 high. Eyes six, eye measurements: ALE 0.06, PLE 0.03, PME 0.03; ALE-PME 0.10, PLE-PLE 0.05, PLE-PME 0.07; AER 0.13, PER 0.15. Chelicera (Fig. 56A) yellow, with eight promarginal teeth and five small retromarginal teeth. Endites and labium yellow. Sternum (Fig. 56B) and legs yellowish. Leg measurements: I 6.86 (1.92, 0.32, 2.04, 1.54, 1.04); II 5.16 (1.52, 0.30, 1.44, 1.02, 0.88); III 4.20 (1.22, 0.30, 1.12, 1.02, 0.54); IV 5.89 (1.66, 0.28, 1.64, 1.39, 0.92). Leg formula: I-IV-II-III. Male palp (Figs 53C <b>–</b> D, 55A–B): tibia with three trichobothria dorsally, four long setae prolaterally and five spines retrolaterally, the basal one thick, conspicuous, with insertion of a short spine apically; tarsus with one thorny spine distally. Tip of the bulb (Fig. 53B): median apophysis short, palm-shaped, distal edge decorated with six small teeth, conductor long, embolus spoon-shaped. <b>Female (one of the paratypes):</b> similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 1.54 (Figs 54A–B). Prosoma 0.81 long, 0.68 wide; Opisthosoma 0.92 long, 0.72 wide. Clypeus 0.12 high. Eye measurement: ALE 0.05, PLE 0.03, PME 0.03; ALE-PME 0.08, PLE-PLE 0.04, PLE-PME 0.04; AER 0.11, PER 0.15. Leg measurements: I 5.01 (1.34, 0.29, 1.46, 1.04, 0.88); II 4.08 (1.06, 0.28, 1.14, 0.88, 0.72); III 3.47 (0.96, 0.24, 0.82, 0.79, 0.66); IV 4.33 (1.22, 0.24, 1.16, 1.03, 0.68). Internal genitalia (Figs 54C, 56D) with a pair of spermathecae and sperm ducts; atrium fusiformed. <b>Variation.</b> Total length: males 1.82–1.86 (n = 8); females (1.54–1.57) (n = 8). <b>Distribution.</b> China (Hunan) (Fig. 72).
