Type material: Holotype: male ( IZCAS) from CHINA: Guangxi: Shuiyuan Cave (Alt.: 573 m; T.: 22˚C; H.: 95%), Sicheng Town, Linyun County [24º21.974΄N, 106º34.646΄E], 14 March 2007, J. Liu and Y.C. Lin leg. Paratypes: 22 males and 75 females ( IZCAS), same data as holotype.

Other material examined. CHINA: Guangxi: 18 males and 41 females ( IZCAS), Naling Cave (Alt.: 528 m; T.: 17˚C; H.: 95%), Sicheng Town, Lingyun County [24º21.921΄N, 106º33.908΄E]; Guangxi: 4 males and 29 females ( IZCAS), Fulong Cave (Alt.: 470 m; T.: 16˚C; H.: 90%), Sicheng Town, Linyun County [24º20.786΄N, 106º33.476΄E], 15 March 2007, J. Liu and Y.C. Lin leg.

Etymology. The specific name of the new species derives from Latin “ spinatus = of thorns, spined” and “ femora = femurs”, and indicates to the femur I bears 2 rows of orderly spines in male.

Diagnosis. The new species is similar to T. dongbei Wang & Ran, 1998 , but can be distinguished by the distinct shape of pedipalpal bulb, the slightly curved and blunt at embolus distally, the presence of 2 rows of spines at femur I anteroventrally in males, the narrow proximally and swollen distally spermatheca (basally broad and distally no swollen in T. dongbei ), and the smaller body size.

Description. Holotype male. Total length 1.26. Prosoma 0.58 long, 0.54 wide. Sternum 0.36 long, 0.30 wide. Opisthosoma 0.70 long, 0.64 wide. Dorsal shield of prosoma yellow, subround, smooth, slightly projecting anteriorly, without modified pattern. Eye absent. Chelicerae yellow, strong, fang furrow with 11 plumose setae, 2 adnate teeth and 3 granulous denticles on promargin, 4 triangular denticles on retromargin. Endites longer than labium, shorter than chelicerae. Sternum yellow, flat, heart-shaped, fused to labium, posterior corner not connected with dorsal shield of prosoma. Legs yellow. Femur I with 2 rows of spines anteroventrally, each patella distally and tibia mesially with a dorsal spine, tibia I and II ventrally with a row of short trichobothria respectively. Leg measurements: I 4.81 (1.38, 0.22, 1.45, 1.12, 0.64); II 4.20 (1.22, 0.21, 1.23, 0.94, 0.60); III 3.06 (0.96, 0.19, 0.85, 0.62, 0.44); IV 3.60 (1.12, 0.20, 1.00, 0.78, 0.50). Leg formula: I- II-IV-III. Opisthosoma pale yellow, covered with sparse long setae, a pair of grayish stains on opisthosoma ventrally.

Pedipalp especially large. Femur equal to 2.5 times of patella in length, with a row of prolateral setae. Tibia equal to 2 times of patella in length, a dorsal trichobothrium on tibia. Tarsus subequal to 2 times of tibia in length, broad proximally, narrow distally, with a prolaterally cymbial apophysis. Pedipalpal bulb nearly rectangular, embolus located at anterolateral corner, short beak-shaped, broad proximally and curved distally. Female. Total length 1.42. Prosoma 0.64 long, 0.58 wide. Sternum 0.40 long, 0.34 wide. Opisthosoma 0.80 long, 0.75 wide. Somatic coloration and modification similar to male. Leg measurements: I 5.04 (1.52, 0.22, 1.54, 1.10, 0.66); II 4.37 (1.32, 0.21, 1.30, 0.94, 0.60); III 3.23 (1.04, 0.20, 0.90, 0.65, 0.44); IV 3.90 (1.24, 0.20, 1.10, 0.84, 0.52). Leg formula: I-II-IV-III. Posterior spinnerets with 5 spines. Colulus tongue-shaped, bears long setae.

Genital area with a row of long setae on postomargin anteriorly, postomargin slightly sclerotized laterally, straight mesially. Another row setae on epigastric furrow posteriorly. Spermatheca narrow proximally, swollen distally, differ reflexed mesially in variety individuals.

Distribution. China (Guangxi) ( Fig. 20 ).
