Leptonetela sexdentata sp. nov.

Figs 53–56, 72

Type material. Holotype: male ( IZCAS), Huanglong Cave , Wuling Reserve [29°37´N, 110°49´E], Zhangjiajie, Hunan, China, 30 October 2005, S. Li leg. Paratypes: 7 males and 8 females, same data as holotype .

Etymology. 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.

Diagnosis. This new species is similar to L. quinquespinata ( Chen & 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).

Description. Male (holotype): 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 – 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.

Female (one of the paratypes): 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.

Variation. Total length: males 1.82–1.86 (n = 8); females (1.54–1.57) (n = 8).
