Type material: Holotype: male ( IZCAS), Laizi Cave , Gaoyan Village, Fuxing Town, Meitan County [27°59´N, 107°36´E, Guizhou, China], 17 May 2006, Y.C. Lin and Z.F. Yang leg. GoogleMaps Paratypes: 1 male and 17 females, same data as holotype ( IZCAS) GoogleMaps .

Etymology. The specific epithet is a noun in apposition and derived from the type locality.

Diagnosis. The new species is similar to L. oktocantha sp. nov., but may be distinguished by the number and arrangement of tibial spurs on pedipalpus, the subround pedipalpal bulb, the position of conductor and embolus, the absence of median apophysis, the extended spermathecae and the triangular atrium.

Description. Holotype male. Total length 1.86. Prosoma 0.90 long, 0.86 wide. Sternum 0.64 long, 0.56 wide. Opisthosoma 1.07 long, 0.89 wide. Dorsal shield of prosoma yellow, a pair of setae on anterolateral area of PEM, short setae along the margin of clypeus anteriorly. Thoracic median groove densely yellow, needleshaped. Cervical groove and radial furrows indistinct. Clypeus 0.20 high, slightly sloped anteriorly. Six eyes, ocular bases black. Eye sizes: ALE 0.06, PLE 0.05, PME 0.04; ALE-ALE 0.01, ALE-PME 0.13, PLE-PLE 0.11, PLE-PME 0.05; AER 0.09, PER 0.15. Major axes of PLE convergent, PME contiguous, median axes parallel. Chelicerae yellow, fang furrow with 8 promarginal and 5 retromarginal teeth. Endites, labium, sternum and legs yellow. Leg measurements: I 7.31 (2.12, 0.36, 2.27, 1.43, 1.13); II 5.95 (1.56, 0.35, 1.78, 1.35, 0.91); III 5.06 (1.32, 0.33, 1.41, 1.15, 0.85); IV 6.41 (1.70, 0.36, 1.87, 1.46, 1.02). Leg formula: I-IV-II- III. Seven or 8 prolateral spines on femur I mesially. One dorsal spine at each patella distally. All tibiae with 3 trichobothria and 7–9 spines. Each metatarsus with only a trichobothrium. A finely serrated hairs-comb at base of metatarsi II and III ventrally. Opisthosoma pale, ovoid, lacking pigmental speckles, covered with hairs.

Pedipalpal femur spineless. A dorsal spine on patella distally. Tibia modified by three dorsal trichobothria and 7 long retrolateral spurs. Tibia subequal to tarsus in length. Tarsus crinkled and contracted mesially, attaching a large earlobe-shaped process with a tuft of thin hairs, 8 long setae on tarsus distally, of them one plumose. Pedipalpal bulb subround, prolateral lobe developed. Conductor and embolus long and contacted at tip. Median apophysis absent.

Female. Similar to male in coloration and general features, but body size larger and legs longer. Total length 2.02. Prosoma 0.95 long, 0.87 wide. Sternum 0.66 long, 0.59 wide. Opisthosoma 1.17 long, 1.00 wide. Clypeus 0.22 high. Six eyes, ocular bases black. Eye sizes: ALE 0.05, PLE 0.05, PME 0.03; ALE-ALE 0.01, ALE-PME 0.12, PLE-PLE 0.05, PLE-PME 0.05; AER 0.08, PER 0.13. Major axes of PLE convergent, PME contiguous, median axes parallel. Chelicerae yellow, fang furrow with 8 promarginal and 5 retromarginal teeth. Endites, labium, sternum and legs yellow. Leg measurements: I 9.78(2.80, 0.43, 2.90, 2.15, 1.50); II 8.17(2.05, 0.42, 2.50, 1.90, 1.30); III 7.65(2.30, 0.40, 2.10, 1.75, 1.10); IV 9.03(2.65, 0.38, 2.60, 2.10, 1.30). Leg formula: I-IV-II-III. Except less spines on femur I, the chaetotaxy and trichobothria of each leg similar to in male.

Genital area covered with densely plumose long hairs. Internal genitalia consisting of a pair of kinkled spermathecae and sperm ducts, widely spaced, faintly sclerotized distally. The atrium triangular and smooth, protruded anteriorly, slightly rugose posteriorly, lacking modified short hairs at atrium and sperm ducts.

Distribution. Known only from type locality.
