Leptonetela lineata sp. nov.

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).

Description. Male (holotype): total length 2.25 ( Fig. 20A). Prosoma 0.90 long, 0.87 wide. Opisthosoma 1.25 long, 1.00 wide. Sternum 0.62 long, 0.55 wide. Prosoma yellowish, with a pair of setae prolateral of PLE. Median groove needle-shaped, brown. Cervical grooves and radial furrow distinct, brown. 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).
