Figs 3–4 , 11C , 14 Type material. CHINA : Guizhou : Holotype : male, Shiqian County , Tongren , Taixu Cave , 27°29’43.50”N , 108°12’33.18”E , ca. 640 m elevation, Huifeng Zhao leg. 12.8.2012 (IZCAS-Ar42303) . Paratypes : 2 females , with same data as for holotype (IZCAS-Ar42304–Ar42305) . Etymology. The specific name refers to the type locality and is a noun in apposition. Diagnosis. The male of this species resembles L. chenjia Wang & Li, 2017 (see Wang et al. 2017: 340 , figs 12– 13, 97) by having a similarly shaped embolus and by the absence of a median apophysis, but it can be distinguished by the presence of six spines on the retrolateral surface of the palpal tibia, with the strongest spine bifurcated distally ( Fig. 3D ) (vs five spines in L. chenjia ), by having a broad, semicircular conductor (vs reduced in L. xianren , Fig. 11D ), and the cymbium is 1.5 times the length of the bulb ( Figs 3C–D ) (vs twice the length in L. chenjia ). Females can be distinguished from L. chenjia by the presence of six eyes. Description. Male ( holotype ): Total length 2.25 ( Fig. 3A ). Carapace 1.00 long, 0.80 wide. Opisthosoma 1.25 long, 0.80 wide. Carapace yellowish. Ocular area with a pair of long setae. Six eyes. Eye sizes: ALE 0.09, PLE 0.08, PME 0.07. Distance between eyes: ALE-PME 0.09, PLE-PLE 0.09, PLE-PME 0.07. Median groove needle shaped, cervical grooves and radial furrows distinct. Clypeus 0.60 high. Opisthosoma grey, ovoid. Leg measurements: I 7.86 (2.30, 0.41, 2.15, 1.75, 1.25); II 6.22 (1.81, 0.30, 1.75, 1.35, 1.01); III – (1.51, 0.30, –, –, –); IV – (2.01, 0.35, –, –, –). Male palp ( Figs 3C–D ): basal part of tibia swollen slightly, tibia with 1 seta and 5 spines retrolaterally, with spine I strongest, asymmetrically bifurcated and located at the base of tibia, spines I and II of equal length. Cymbium constricted medially, attached to a small, earlobe-shaped process retrolaterally. Embolus triangular, prolateral lobe oval. Median apophysis absent. Conductor broad, semicircular in ventral view ( Figs 3B , 11C ). Female ( paratype , IZCAS-Ar42304): Similar to male in colour and general features but larger and with shorter legs. Total length 2.45 ( Figs 4A–B ). Carapace 1.15 long, 0.80 wide. Opisthosoma 1.30 long, 0.95 wide. Clypeus 0.75 high. Six eyes. Eye sizes: ALE 0.07, PLE 0.07, PME 0.03. Distance between eyes: ALE-PME 0.11, PLE-PLE 0.07, PLE-PME 0.09. Leg measurements: I 7.77 (2.10, 0.40, 2.21, 1.74, 1.32); II 5.98 (1.75, 0.40, 1.63, 1.31, 0.89); III 5.22 (1.51, 0.35, 1.36, 1.22, 0.78); IV 6.83 (2.06, 0.40, 1.96, 1.51, 0.90). Vulva ( Fig. 4C ): spermathecae coiled, atrium trapezoidal. Distribution. Guizhou , China ( Fig. 14 ).
