Type material: Holotype: male ( IZCAS) from CHINA: Yunnan: Laobie Cave (Alt.: 1840 m; T.: 10 ˚C; H.: 90%), Pingtian Village, Luoxiong Town, Luoping County [24º50.511΄N, 104º16.066΄E], 20 March 2007, J. Liu and Y.C. Lin leg. Paratypes: 2 males and 11 females ( IZCAS), same data as holotype.
Other material examined. CHINA: Yunnan: 3 males and 15 females ( IZCAS), a nameless cave (Alt.: 1615 m; T.: 11˚C; H.: 85%), Pingtian Village, Luoxiong Town, Luoping County [24º50.928΄N, 104º16.483΄E], same date and collectors as holotype.
Etymology. The specific name derives from Latin “ vesiculatus = vesicular”, and in reference to the spermatheca appending a small vesicle ventral-distally.
Diagnosis. The new species is similar to T. spina Tong & Li, 2008 , but can be distinguished by the absence of eyes and strong tarsal spine on male pedipalp distally (present in T. spina ), the distinct shape of embolus, the club-shaped spermatheca slightly curved mesially and swollen distally (unknown in T. spina ), and the larger body size.
Description. Holotype male. Total length 1.76. Prosoma 0.76 long, 0.70 wide. Sternum 0.50 long, 0.36 wide. Opisthosoma 0.92 long, 0.82 wide. Dorsal shield of prosoma yellow, flat, nearly circular, with few setae on mid-anterior area. Eye absent. Chelicerae yellow, longer than endites, fang furrow with 2 teeth and 3 tiny granulous denticles on promargin, 4 small triangular teeth on retromargin, 11 plumose setae along cheliceral promargin. Endites long same as wide, wide proximally and narrow distally, serrula invisible. Labium length equal to 2/3 times of width, base darkish, fused to sternum. Sternum planar, triangular, longer than wide, covered with dispersive setae on surface, margins flexural laterally, posterior corner sharp. Femora spineless. One dorsal long spine on each patella distally, and as same as on tibiae mesially. Leg measurements: I 6.87 (2.06, 0.27, 2.20, 1.46, 0.88); II 5.82 (1.80, 0.26, 1.84, 1.16, 0.76); III 4.24 (1.38, 0.24, 1.16, 0.86, 0.60); IV 5.20 (1.68, 0.24, 1.46, 1.14, 0.68). Leg formula: I-II-IV-III. Opisthosoma light yellow, covered with long setae.
Pedipalpal bulb large, egg-shaped. Femur subequal to 2 times of patella in length. Tibia subequal to 2 times of patella, and to 5/8 times of tarsus in length, with a dorsal trichobothrium mesially. Tarsus longer distinctly than femur, prolaterally cymbial apophysis present. A triangular embolus anear apex of pedipalpal bulb, which is membranous on postomargin, slightly sclerotized on anteromargin.
Female. Total length 1.74. Prosoma 0.80 long, 0.70 wide. Sternum 0.46 long, 0.36 wide. Opisthosoma 0.90 long, 0.86 wide. Somatic coloration and modified spines of legs same as in male. Leg measurements: I 6.28 (1.90, 0.28, 1.96, 1.34, 0.80); II 5.44 (1.68, 0.26, 1.70, 1.10, 0.70); III 3.92 (1.26, 0.22, 1.08, 0.80, 0.56); IV 4.93 (1.60, 0.23, 1.40, 1.10, 0.60). Leg formula: I-II-IVI-II. Median spinnerets with 4, posteriors with 3 large spines.
Genital area with several irregular setae on postomargin anteriorly, a row of short setae on epigastric furrow posteriorly. Postomargin weakly sclerotized laterally, concave mesially. Spermatheca club-shaped, slightly curved mesially and swollen distally, appending a small vesicle ventral-distally. Distribution. China (Yunnan) ( Fig. 20 View FIGURE 20 ).
