Type material: Holotype: male ( IZCAS), Yelaodadong Cave (Alt.: 1438 m; T.: 9 ºC; H.: 94%), Sanhe Village , Wenge Town, Dafang County [27°10.900´N, 105°28.278´E, Guizhou, China], 3 May 2007, Y.C. Lin and J. Liu leg. GoogleMaps Paratypes: 22 males and 55 females, same data as holotype ( IZCAS) GoogleMaps .

Etymology. The specific name is derived from the Latin adjective " curvispinosus " (= with curving spine), in reference to the presence of a horn-shaped large basal spine at the pedipalpal tarsus prolaterally. Gender is feminine.

Diagnosis. The new species can be distinguished from all the other congeners by the presence of a hornshaped large spur on the prolateral base of pedipalpal tarsus, the non-contracted pedipalpal tarsus, the equidistant arranged five tibial spurs and the absence of a median apophysis in the male pedipalp.

Description. Holotype male. Total length 2.28. Prosoma 1.04 long, 0.96 wide. Sternum 0.62 long, 0.30 wide. Opisthosoma 1.28 long, 0.98 wide. Dorsal shield of prosoma yellow, two pair of long setae at antrolateral and retrolateral area of PEM, clypeal margin with many short setae anteriorly. Thoracic median groove indistinct. Cervical groove and radial furrows distinct, pale brown. Clypeus 0.22 high, slightly sloped anteriorly. Six eyes, with darkish bases. Eye sizes: ALE 0.06, PLE 0.06, PME 0.06; ALE-ALE 0.01, ALE- PME 0.12, PLE-PLE 0.10, PLE-PME 0.06; AER 0.13, PER 0.16. Major axes of PLE convergent behind, median axes of PME parallel. Chelicerae yellow, fang furrow with 8 promarginal and 7 retromarginal teeth. Endites and labium pale yellow. Sternum and legs yellow. Leg measurements: I 15.20 (4.25, 0.40, 4.75, 3.65, 2.15); II 10.28 (3.00, 0.38, 3.05, 2.25, 1.60); III 8.20 (2.40, 0.35, 2.35, 1.85, 1.25); IV 10.60 (3.10, 0.35, 3.10, 2.55, 1.50). Leg formula: I-IV-II-III. Femur I with only one spine. Each patella with a dorsal spine distally. Three trichobothria and 2 or 3 spines modified tibiae I–IV respectively. Each metatarsus with only one trichobothrium. A finely serrated hairs-comb on ventral base of metatarsi II and III severally. Opisthosoma grey, ovoid, anteriorly pale and posteriorly dim, lacking pigmental speckle.

Pedipalpal femur without modified large spines, a dorsal spine on the patella distally. Three dorsal trichobothria, 3 prolateral long spines modified pedipalpal tibia, and 5 retrolateral strong spurs equidistant arranged. Pedipalpal tarsus no rugose, with a mesial spine retrolaterally, a distal and a proximal spurs prolaterally. Pedipalpal bulb subround, a horn-shaped embolus located at bulbous apex. Median apophysis absent, conductor undeveloped.

Female. Similar to male in coloration and general features, but body size larger and legs shorter. Total length 2.40. Prosoma 1.02 long, 0.92 wide. Sternum 0.60 long, 0.60 wide. Opisthosoma 1.42 long, 1.24 wide. Clypeus 0.22 high. Six eyes. Eye sizes: ALE 0.07, PLE 0.07, PME 0.05; ALE-ALE 0.02, ALE-PME 0.12, PLE-PLE 0.09, PLE-PME 0.06; AER 0.16, PER 0.19. Chelicerae pale brown, fang furrow with 8 promarginal and 6 or 7 retromarginal teeth. Endites and labium pale brown. Sternum and legs yellow. Leg measurements: I 11.46 (3.10, 0.38, 3.48, 2.65, 1.85); II 8.66 (2.45, 0.35, 2.50, 1.93, 1.43); III 7.08 (2.10, 0.33, 1.95, 1.55, 1.15); IV 9.10 (2.65, 0.35, 2.60, 2.15, 1.35). Leg formula: I-IV-II-III. The chaetotaxy of each leg same as in male.

Genital area covered with densely plumose long hairs. Internal genitalia consist of a pair of kinkled spermathecae and sperm ducts, slightly sclerotized, attaching modified short hairs. The atrium fusiform, anterior and posterior margin smooth.
