Types.

Holotype: ♂ (IZCAS), China, Tibet Autonomous Region, Nyingchi, Shergyla Mountain, 29°33.7980'N, 94°34.2060'E, elevation ca 3764 m, 15.VII.2019, X. Zhang, Z. Bai and J. Liu leg. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

The species name is an adjective referring to the type locality.

Diagnosis.

Males of L. shergylaensis sp. nov. resemble L. pulongensis sp. nov. and L. duibaensis sp. nov. but can be distinguished by the presence of a conductor (Fig. 46B View Figure 46 ) (vs. absence of a conductor in L. pulongensis sp. nov. (Fig. 48B View Figure 48 ) and L. duibaensis sp. nov. (Fig. 52B View Figure 52 )), two retrolateral apophyses bearing a spine on the tibia (Fig. 46D View Figure 46 ) (vs. a prolateral apophysis bearing a hooked spine on the tibia in L. pulongensis sp. nov. (Fig. 48C View Figure 48 )) and a retrolateral apophysis bearing spine on tibia in L. duibaensis sp. nov. (Fig. 52D View Figure 52 )), absence of strong setae in both L. shergylaensis sp. nov. and L. duibaensis sp. nov. (vs. the presence of strong setae on the tibia anteriorly in L. pulongensis sp. nov. (Fig. 48D View Figure 48 )), and the absence of a bulge on the bulb of both L. shergylaensis sp. nov. and L. pulongensis sp. nov. (vs. the presence of a bulge on the bulb of L. duibaensis sp. nov. (Fig. 52B View Figure 52 )), absence of an apophysis on the cymbium in both L. shergylaensis sp. nov. and L. pulongensis sp. nov. (vs. the presence of a retrolateral apophysis bearing four spines on the cymbium in L. duibaensis sp. nov. (Fig. 52D View Figure 52 )), and the tibia swollen angularly (Fig. 46C View Figure 46 ) (vs. tibia roundly swollen in both L. pulongensis sp. nov. and L. duibaensis sp. nov.).

Description.

Male (Holotype). Total length 3.13; carapace 1.00 long, 1.13 wide; abdomen 2.13 long, 1.09 wide. Carapace round and brown, with median dark brown band (Fig. 45C View Figure 45 ). Chelicerae brown (Fig. 57C View Figure 57 ). Clypeus pale brown. Endites dark brown, light brown basally. Labium dark brown. Sternum dark brown, with short light brown band medially. Abdomen elongated, dorsum with dark brown spots, posterior with dark brown horizontal stripes, antero-ventrally with dark brown inverted fan-shaped pattern medially and kidney-shaped pattern laterally, posterior dark brown with two light vertical traces medially. Legs uniformly brown; measurements: I 9.60 (2.60. 0.40. 3.00, 2.40, 1.20), II 8.94 (2.60, 0.40, 2.50, 2.24, 1.20), III missing, IV 9.20 (2.60, 0.40, 2.80, 2.20, 1.20). Palp (Fig. 46A-D View Figure 46 ): femur slender, four times longer than patella; patella not swollen; tibia swollen pentagonally, similar length to, and 2 times wider than femur, with two retrolateral apophyses bearing spine (Fig. 46D View Figure 46 ) (one apophysis on anterior, the other medially on tibia), spine and apophysis similar in length; cymbium two times shorter than femur, dark brown distally; bulb brown, ovate, with embolus, laminar apophysis, and conductor arising distally; embolus thin, two times longer than conductor and laminar apophysis; branched laminar apophysis, two times wider than embolus, adjacent to conductor; conductor branched, with the longer branch longer than laminar apophysis, attached to embolus (Fig. 46B View Figure 46 ).

Female (Paratype). General features and coloration similar to those of male (Fig. 45D, E View Figure 45 ). Measurements: total length 2.44; carapace 0.94 long, 1.00 wide; abdomen 1.50 long, 0.88 wide. Leg measurements: I 7.69 (2.24, 0.31, 2.34, 1.80, 1.00), II 6.70 (1.80, 0.31, 2.03, 1.56, 1.00), III 5.29 (1.41, 0.31, 1.38, 1.25, 0.94), IV 6.10 (1.80, 0.31, 2.19, 1.80, 1.00). Epigastric area (Fig. 45B View Figure 45 ): elliptical dark brown patch with distinct whitish slit. Endogyne (Fig. 45A View Figure 45 ): a pair of ovoid spermathecae, thickening at margins.
