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.
