Types.

Holotype: ♂ (IZCAS), China, Tibet Autonomous Region, Nyingchi, Medog County, Medog Town, road to Renqinbeng Temple, 29°18.4260'N, 95°21.5100'E, elevation ca 2036 m, 21.VII.2019, X. Zhang, Z. Bai and J. Liu. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

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

Diagnosis.

Males of L. renqinensis sp. nov. resemble L. tudao sp. nov. but can be distinguished by the presence of four uneven retrolateral apophyses on a swollen tibia, with one apophysis bearing a spine (Fig. 44C View Figure 44 ) (vs. the presence of a spine and three retrolateral apophyses bearing spines on a swollen tibia (Fig. 50C View Figure 50 )), tibia swollen pentagonally (Fig. 44C View Figure 44 ) (vs. tibia swollen triangularly (Fig. 50C View Figure 50 )), pyriform bulb rather slender and elongated (Fig. 44B View Figure 44 ) (vs. pyriform bulb rather plump (Fig. 50B View Figure 50 )), a thin strip of the conductor arises at the margins (Fig. 44B View Figure 44 ) (vs. a wide part of the conductor arises at the margins), laminar apophysis and embolus not attached to each other (Fig. 44B View Figure 44 ) (vs. embolus attached to laminar apophysis); females can be recognized by having a pair of spermathecae resembling a bow (Fig. 43A View Figure 43 ) (vs. a pair of stalked spermathecae (Fig. 49A View Figure 49 )), external genitalia with triangular orange area (Fig. 43B View Figure 43 ) (vs. dark brown area (Fig. 49B View Figure 49 )).

Description.

Male (Holotype). Total length 3.30; carapace 0.96 long, 1.09 wide; abdomen 2.34 long, 1.25 wide. Carapace round and brown, with three dark brown longitudinal bands, median band six times wider than lateral band (Fig. 43C View Figure 43 ). Chelicerae brown (Fig. 57B View Figure 57 ). Clypeus pale brown. Endites dark brown, light brown basally. Labium dark brown. Sternum dark brown laterally, light brown medially. Abdomen elongated, dorsum with brown spots, posterior with dark brown horizontal stripes, antero-ventrally with distinct triangular orange area, posterior with dark brown bands laterally, scattered brown spots medially. Legs uniformly brown; measurements: I 16.00 (4.25, 0.40, 4.75, 5.00, 1.60), II 11.61 (3.21, 0.40, 3.20, 3.40, 1.40), III 7.71 (2.20, 0.31, 2.20, 2.00, 1.00), IV 12.50 (3.85, 0.40, 3.50, 3.50, 1.25). Palp (Fig. 44A-D View Figure 44 ): femur slender, five times longer than patella; patella not swollen; tibia swollen pentagonally, 1.2 times shorter and 4 times wider than femur, with four retrolateral apophyses anteriorly (Fig. 44C View Figure 44 ) (one apophysis bearing a spine, three others with rounded tip, with apophysis one being longest); cymbium three times shorter than femur, brown; bulb brown, pyriform, with embolus, laminar apophysis, and conductor arising distally; embolus black and slender, longer than laminar apophysis and conductor; laminar apophysis with blunt tip, two times wider and not attached to embolus; conductor brown, arising marginally as a thin strip, embolus three times wider and longer than conductor (Fig. 44B View Figure 44 ).

Female (Paratype). General features and coloration similar to those of male (Fig. 43D, E View Figure 43 ). Measurements: total length 2.82; carapace 0.94 long, 1.00 wide; abdomen 1.88 long, 1.00 wide. Leg measurements: I 12.65 (2.75, 0.40, 4.00, 4.00, 1.50), II 10.11 (2.80, 0.31, 3.00, 2.80, 1.20), III 9.06 (1.75, 0.31, 3.00, 2.80, 1.20), IV 10.80 (3.00, 0.40, 3.20, 3.00, 1.20). Epigastric area (Fig. 43B View Figure 43 ): distinct triangular orangeish patch with pale brown crescent at base. Endogyne (Fig. 43A View Figure 43 ): spermathecae resemble a ribbon knot with a pair of ovoid droplet-shaped marks, receptacles with rounded upturned ends.
