Type material: Holotype: male ( IZCAS) from CHINA: Guizhou: Mahuang Cave (Alt.: 730 m; T.: 13 ˚C; H.: 90 %), Guihua  Village, Wenquan Town, Suiyang County [28 º 14.619 ΄N, 107 º 17.345 ΄E], 16 May 2007, J. Liu and Y.C. Lin leg. Paratypes: 8 males and 14 females ( IZCAS), same data as holotype.

Etymology. The specific epithet of the new species refers to the type locality.

Diagnosis. The new species is similar to T. claviformis Tong & Li, 2008  and T. wunderlichi Song & Zhu, 1994  , but can be distinguished by the absence of cymbial apophysis of male pedipalp, the distinct shape of embolus and bulb, the parallel chelicerae, the pedipalpal tarsus slightly swollen distally, the outcurving postomargin of genital area, the straight spermatheca and the smaller body size.

Description. Holotype male. Total length 1.24. Prosoma 0.50 long, 0.46 wide. Sternum 0.32 long, 0.31 wide. Opisthosoma 0.68 long, 0.62 wide. Dorsal shield of prosoma yellow, sleek, subround. Eye absent. Chelicerae, endites, labium, sternum and legs same color as dorsal shield of prosoma. Chelicerae small, longer slightly than endites, fang furrow with sole large promarginal tooth and 5 small granulated retromarginal teeth, a row of plumose setae along cheliceral promargin. Endites length subequal 2 times to width, serrula invisible. Labium semicircular, length equal to 1 / 2 times its width, base darkish and bears several short setae, fused to sternum. Sternum slightly plump, heart-shaped, black setae on surface, posterior corner blunt. One dorsal spine at each patella distally, tibia spineless. Leg measurements: I 3.98 (1.26, 0.20, 1.12, 0.84, 0.56); II 3.65 (1.18, 0.19, 1.00, 0.76, 0.52); III 2.76 (0.88, 0.16, 0.70, 0.60, 0.42); IV 3.22 (1.02, 0.17, 0.82, 0.73, 0.48). Leg formula: I-II-IV-III. Opisthosoma pale yellow, bears few long setae.

Pedipalp large. Femur subequal 2.5 times to patella in length, tibia subequal 1.5 times to patella in length, a dorsal trichobothrium on the one third of tibia distally, tarsus longer than femur, cymbial apophysis absent. Pedipalpal bulb oval, anear bulbous apex extended into a beak-shaped embolus.

Female. Total length 1.16. Prosoma 0.50 long, 0.48 wide. Sternum 0.32 long, 0.30 wide. Opisthosoma 0.64 long, 0.58 wide. Somatic coloration same as in male. Femur I and tibia I without long spines. Each patella with a dorsal spine distally. Leg measurements: I 3.80 (1.18, 0.20, 1.08, 0.78, 0.56); II 3.46 (1.08, 0.18, 0.98, 0.72, 0.50); III 2.68 (0.86, 0.16, 0.70, 0.56, 0.40); IV 3.13 (1.02, 0.17, 0.80, 0.67, 0.47). Leg formula: I- II-IV-III. Median spinnerets with 3, posteriors 4 short spines.

Genital area protected by a row of setae. Postomargin slightly sclerotized laterally. Spermatheca straight, club-shaped, slightly bent proximally, swollen distally.

Distribution. China (Guizhou) ( Fig. 20View FIGURE 20).
