Figs 65–68, 72

Type material. Holotype: male ( IZCAS), Taoyuan Cave [25°03´N, 109°13´E], Rongshui County, Guilin City, Guangxi, China, 23 July 2009, C. Wang & Z. Yao leg. Paratypes: 9 females, same data as holotype .

Etymology. The specific name is in honor of the collector Z. Yao (Zhiyuan Yao, Institute of Zoology, Chinese Academy of Sciences, Beijing); noun.

Diagnosis. This new species is similar to L. kanellisi ( Deeleman-Reinhold, 1971) , but can be distinguished by the presence of six eyes ( Figs 65A, 66A); the eight promarginal cheliceral teeth, the distal one largest, the distal three wider spaced and four small retromarginal teeth ( Fig. 68C); five spines on the retrolateral surface of palpal tibia, the basal one strong, conspicuous ( Figs 65C–D, 67B); the absence of median apophysis in the male; and the presence of slender hairs on the anterior margin of atrium in the female ( Figs 66C, 68B).

Description. Male (holotype): total length 2.30 ( Figs 65A–B). Prosoma 1.07 long, 0.90 wide. Opisthosoma 1.15 long, 0.96 wide. Sternum 0.72 long, 0.64 wide. Prosoma yellow, with a pair of setae retrolateral of PLE. Median groove needle-shaped, pale brown. Cervical grooves and radial furrow indistinct. Eyes six, eye measurements: ALE 0.08, PLE 0.05, PME 0.06; ALE-PME 0.08, PLE-PLE 0.12, PLE-PME 0.05; AER 0.18, PER 0.22. Clypeus 0.15 high, slightly sloped anteriorly. Chelicera ( Fig. 68C) brown, with eight promarginal teeth, the distal one largest, the distal three wider spaced and four small retromarginal teeth. Endites and labium brown. Sternum and legs yellowish. Leg measurements: I 8.92 (2.45, 0.37, 2.50, 2.15, 1.45); II 7.70 (2.00, 0.35, 2.35, 1.85, 1.15); III 6.70 (2.10, 0.30, 1.75, 1.60, 0.95); IV 8.37(2.25, 0.37, 2.40, 2.05, 1.30). Leg formula: I-IV-II-III. Femur I with one long spine dorsally (position 0.3). Femur II with two long spines dorsally (0.3 and 0.5). Male palp ( Figs 65C– D, 67A–B): tibia with three trichobothria dorsally, one long seta and five spines retrolaterally, with the basal one strong, conspicuous; tarsus with five thorny spines distally. Tip of the bulb: median apophysis absent, conductor lamellar, embolus rectangular.

Female (one of the paratypes): similar to male in coloration and general features, but with a larger body size and shorter legs. Total length 2.37 ( Figs 66A–B). Prosoma 1.20 long, 0.86 wide. Opisthosoma 1.37 long, 1.06 wide. Sternum 1.87 long, 1.62 wide. Clypeus 0.13 high. Eye measurements: ALE 0.09, PLE 0.06, PME 0.07; ALE- PME 0.08, PLE-PLE 0.13, PLE-PME 0.06; AER 0.18, PER 0.24. Leg measurements: I 7.72 (2.25, 0.35, 2.15, 1.80, 1.17); II 6.47 (1.80, 0.30, 1.87, 1.40, 1.10); III 5.54 (1.62, 0.30, 1.50, 1.25, 0.87); IV 7.27 (2.10, 0.35, 2.00, 1.70, 1.12). Internal genitalia ( Figs 66C, 68B) with a pair of spermathecae and sperm ducts; atrium fusiformed, anterior margin of atrium decorated with slender hairs.

Variation. Total length: females (2.35–2.40) (n = 9).
