Type material. CHINA: Guizhou: Holotype: male, Qiannan, Sandu County, Sandong Township , Banmen Village , San Cave , 25°43’00.12”N, 107°55’47.76”E, ca. 500 m elevation, Jincheng Liu and Huifeng Zhao leg. 20.3.2013 (IZCAS-Ar42301) . Paratype: 1 female, with same data as for holotype (IZCAS-Ar42302) .

Etymology. The specific name is a patronym honouring Prof. Dr Jochen Martens (Mainz, Germany) for his zoological studies in Pan-Himalaya; name in the genitive case.

Diagnosis. This species resembles L. dao Wang & Li, 2017 (see Wang et al. 2017: 335, figs 6–7, 97) with a similar shape of the conductor, but the males can be distinguished by three long setae on the prolateral surface of the palpal tibia ( Fig. 1C ), (vs five setae in L. dao ), six spines on the retrolateral surface of the palpal tibia ( Fig. 1D ), (vs five spines in L. dao ), and the median apophysis with the presence of four tooth-shaped apophyses distally (vs median apophysis divided into two pine needle like structures in L. dao , Fig 11B ). Females can be distinguished by the rectangular atrium (vs atrium triangular in L. dao ).

Description. Male (holotype): Total length 2.20 ( Fig. 1A ). Carapace 0.95 long, 0.75 wide. Opisthosoma 1.25 long, 0.85 wide. Carapace yellowish. Ocular area with a pair of long setae. Six eyes. Eye sizes: ALE 0.08, PLE 0.07, PME 0.05. Distance between eyes: ALE-PME 0.13, PLE-PLE 0.10, PLE-PME 0.08. Median groove needle-shaped, cervical grooves and radial furrows distinct. Clypeus 0.75 high. Opisthosoma gray, ovoid. Leg measurements: I 10.23 (2.85, 0.51, 2.91, 2.35, 1.61); II – (2.34, 0.35, –, –, –); III 6.75 (2.01, 0.25, 1.76, 1.61, 1.12); IV 7.18 (2.48, 0.41, 2.41, 1.25, 0.63). Male pedipalp ( Figs 1C–D ): tibia with 3 long setae prolaterally and 7 spines retrolaterally, tibia I spine longest. Cymbium constricted medially, attached to a small earlobe-shaped process retrolaterally. Embolus semicircular, prolateral lobe oval. Median apophysis long and thin, with 4 small teeth distally. Conductor triangular ( Figs 1B , 11A ).

Female (paratype): Similar to male in color and general features, but larger and with shorter legs. Total length 2.21 ( Figs 2A–B ). Carapace 0.81 long, 0.85 wide. Opisthosoma 1.40 long, 1.10 wide. Clypeus 0.50 high. Six eyes. Eye sizes:ALE 0.08, PLE 0.08, PME 0.04. Distance between eyes: ALE-PME 0.12, PLE-PLE 0.10, PLE-PME 0.08. Leg measurements: I 8.65 (2.52, 0.44, 2.54, 1.91, 1.24); II 7.10 (2.25, 0.34, 1.96, 1.62, 0.93); III 5.76 (1.74, 0.34, 1.51, 1.25, 0.92); IV 7.17 (2.26, 0.40, 2.06, 1.35, 1.10). Vulva ( Fig. 2C ): spermathecae coiled, atrium rectangular.

Distribution. Guizhou, China ( Fig. 14 ).
