Figs 33 , 34 , 55B , 58 Types. Holotype : ♂ (IZCAS), China, Tibet Autonomous Region, Xigaze, Nyalam County, Zham Town, 27°59.0250'N , 85°58.9720'E , elevation ca 2450 m, 29.VIII.2014, Y. Li leg. Etymology. The species name is an adjective referring to the type locality. Diagnosis. Males of L. zhamensis sp. nov. can be distinguished from congeners by the laminar-shaped embolus that is basally fused with the conductor (Fig. 34B ) (vs. the absence of a basally fused conductor and embolus in congeners); the presence of a retrolateral apophysis on the tibia with a spine four times shorter than the apophysis (Fig. 34D ) (vs. the absence of a spine with such characteristics in congeners). Figure 33. Leclercera zhamensis sp. nov., male holotype. A Habitus, dorsal view B habitus ventral view. Description. Male (Holotype). Total length 3.84; carapace 1.28 long, 1.25 wide; abdomen 2.56 long, 0.88 wide. Carapace round and brown, with three dark brown longitudinal bands, median band 3 times wider than lateral bands (Fig. 33A ). Chelicerae brown (Fig. 55B ). Clypeus brown, with dark brown band medially. Endites dark brown, light brown basally. Labium and sternum dark brown. Abdomen elongated, antero-dorsally with three pairs of dark brown spots laterally, pale brown medially, posterior with dark brown stripes medially, antero-ventrally with dark brown patch, and a pair of longitudinal dark brown bands laterally, with dark brown posterior patches laterally. Legs uniformly brown; measurements: I 24.21 (7.05, 0.50, 7.37, 7.05, 2.24), II 17.81 (5.13, 0.50, 5.13, 5.13, 1.92), III 11.53 (3.53, 0.40, 3.00, 3.00, 1.60), IV 17.32 (4.81, 0.50, 5.13, 5.13, 1.75). Palp (Fig. 34A-D ): femur slender, six times longer than patella; patella not swollen; tibia slightly swollen anteriorly, 1.5 times shorter than femur, with an anterior retrolateral apophysis bearing a spine four times shorter than the apophysis (Fig. 34D ); cymbium dark brown anteriorly, 2.5 times shorter than femur; bulb brown, semicircle with conductor and embolus arising distally; conductor dark and thin, basally fused with embolus, almost as long as embolus, two times longer than tegulum; embolus laminar-like, almost transparent (Fig. 34B ). Female . Unknown. Distribution. Known only from the type locality (Fig. 58 ). Figure 34. Leclercera zhamensis sp. nov.
