Types.

Holotype: ♂ (IZCAS), China, Tibet Autonomous Region, Nyingchi, Bomê County, Yigong Village, mountain in Jiazhong Village, 30°11.2620'N, 94°19.4180'E, elevation ca 3087 m, 18.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. jiazhongensis sp. nov. resemble L. aniensis sp. nov. but can be distinguished by the presence of a prolateral apophysis bearing a spine on the tibia (Fig. 54D View Figure 54 ) (vs. the presence of two retrolateral apophyses, each bearing a spine, on the tibia, where the anterior apophysis is branched and resembles a claw (Fig. 42D View Figure 42 )), cymbium similar in length to tibia (vs. cymbium about three times shorter than the tibia), tibia swollen, resembles “D” shape (vs. tibia swollen, resembles isosceles triangle), bulb rather slender and elongated (Fig. 54B View Figure 54 ) (vs. bulb rather plump and short (Fig. 42B View Figure 42 )), and the presence of one laminar apophysis (vs. the presence of three laminar apophyses); females can be distinguished by a pair of long, wavy, stalked spermathecae (Fig. 53A View Figure 53 ) (vs. a pair of short and upturned stalked spermathecae (Fig. 41A View Figure 41 )).

Description.

Male (Holotype). Total length 3.44; carapace 0.94 long, 1.13 wide; abdomen 2.50 long, 1.13 wide. Carapace round and brown, with three dark brown longitudinal bands, median band four times wider than lateral band (Fig. 53C View Figure 53 ). Chelicerae brown (Fig. 57G View Figure 57 ). Clypeus brown, dark brown medially. Endites dark brown, light brown basally. Labium dark brown. Sternum with dark brown stripes. Abdomen elongated, dorsum with three pairs of dark brown spots laterally, posterior with dark brown horizontal stripes, antero-ventrally with a pair of kidney-shaped dark brown spots laterally, followed by elliptical dark brown region, posterior dark brown, delimiting vertical light brown lines laterally. Legs uniformly brown; measurements: I 10.84 (2.24, 0.40, 3.60, 3.00, 1.60), II 10.60 (3.00, 0.40, 3.20, 2.75, 1.25), III 7.49 (2.20, 0.40, 2.00. 1.80, 1.09), IV 10.55 (3.00, 0.40, 3.00, 2.75, 1.40). Palp (Fig. 54A-D View Figure 54 ): femur slender, five times longer than patella; patella not swollen; tibia swollen forming a “D” shape, 2 times shorter and only slightly wider than femur, with a prolateral apophysis bearing spine anteriorly, spine two times shorter than apophysis (Fig. 54D View Figure 54 ); cymbium two times shorter than femur, similar in length but two times narrower than tibia; bulb brown, pyriform, with embolus, laminar apophysis, and conductor arise distally; embolus black and slender, widest between laminar apophysis and conductor, similar in length to conductor and two times longer than laminar apophysis; laminar apophysis appears to be shortest, basally connected to embolus; conductor alongside embolus, and similar in width to embolus (Fig. 54B View Figure 54 ).

Female (Paratype). General features and coloration similar to those ofmale (Fig. 53D, E View Figure 53 ). Measurements: total length 3.00; carapace 1.00 long, 1.00 wide; abdomen 2.00 long, 1.50 wide. Leg measurements: I 10.51 (2.80, 0.31, 3.20, 2.60, 1.60), II 9.35 (2.75, 0.40, 2.75, 2.25, 1.20), III 6.46 (1.75, 0.31, 1.80, 1.60, 1.00), IV 9.32 (2.60, 0.31, 2.66, 2.34, 1.41). Epigastric area (Fig. 53B View Figure 53 ): semi-circular dark brown patch. Endogyne (Fig. 53A View Figure 53 ): pair of lengthy, stalked spermathecae with anterior wavy horizontal part and twisted vertical posterior part, both parts with rounded tips, posterior ends with a pair of elliptical bodies.
