Figs 20–23, 72

Type material. Holotype: male (IZCAS), Mingyang Cave, Xingtian Village, Pengzha Town, Xingyi [25°26´N, 105°11´E], Guizhou, China, 27 June 2006, H. Chen leg. Paratypes: 5 females, same data as holotype.

Etymology. The specific name is from Latin word, “linea”, meaning “line”, and refers to the line-like anterior margin of atrium in the female; adjective.

Diagnosis. This new species is similar to L. tongzi Lin & Li 2010 and L. chiosensis sp. nov., but can be distinguished from L. tongzi by the presence of eight promarginal cheliceral teeth and five small retromarginal teeth (Fig. 23C); five spines retrolateral of male palpal tibia, with the basal two equal length and strong, the distal three situate in triangular (Figs 20D, 22B); from L. chiosensis sp. nov. by the presence of eight promarginal cheliceral teeth and five small retromarginal teeth (Fig. 23C); the absence of median apophysis; the distinct shape of conductor in the male (Figs 20B, 23D); and the line-like anterior margin of atrium in the female (Figs 21C, 23B).

Eyes six, reduced to white spots, eye measurements: ALE 0.04, PLE 0.05, PME 0.05; ALE-PME 0.12, PLE-PLE 0.06, PLE-PME 0.10; AER 0.08, PER 0.16. Clypeus 0.12 high, slightly sloped anteriorly. Chelicera (Fig. 23C) dark yellow, with eight promarginal teeth and five small retromarginal teeth. Endites and labium dark yellow. Sternum and legs yellowish.

Leg formula: I-IV-II-III. Femur I II with one long spine dorsally (position 0.3). Femur III IV with two long spines dorsally (0.3 and 0.6). Male palp (Figs 20C–D, 22A–B): tibia with three trichobothria dorsally, one long seta and five spines retrolaterally, with the basal two spines equal length and strong, the distal three situate in triangular; middle part of tarsus with an earlobe-shaped process, which decorated with a short spine; tarsus with three long spines distally. Tip of the bulb (Figs 20B, 23D): median apophysis absent, conductor lamellar, embolus triangular.

Female (one of the paratypes): total length 3.00 (Figs 21A–B). Prosoma 1.25 long, 1.00 wide. Opisthosoma 1.90 long, 1.60 wide. Sternum 0.62 long, 0.60 wide. Prosoma brown, opisthosoma yellow. Clypeus 0.25 high. Eye measurements: ALE 0.05, PLE 0.04, PME 0.04; ALE-PME 0.14, PLE-PLE 0.08, PLE-PME 0.08; AER 0.10, PER 0.16. Leg measurements: I 9.35 (2.75, 0.30, 2.80, 2.00, 1.50); II 7.25 (2.25, 0.30, 2.00, 1.60, 1.10); III 6.55 (2.00, 0.25, 1.80, 1.50, 1.00); IV 8.45 (2.50, 0.30, 2.40, 2.00, 1.25).
