Type. Male holotype, 1Ƥ paratype, CHINA: Guizhou Province, Ceheng County, Yanjia Town, Guojia Cave [25°16’N, 105°54’E], May 22, 2006, leg. by H. M. Chen.
Diagnosis. This new species is similar to P. anlong , easily distinguished by the tip shape of procursus ( Figs 11– 13 View FIGURES 9 – 15 ); by the larger process of appendix centrally ( Fig. 12 View FIGURES 9 – 15 ); by the shape of uncus ( Fig. 12 View FIGURES 9 – 15 ); also by epigynum with long oval pore plate and the shape of sclerotized arch anteriorly ( Fig. 15 View FIGURES 9 – 15 ).
Etymology. The species name is a noun in apposition, taken from the type locality.
Description. Male (holotype): total body length 5.0: cephalothorax 1.4 long, 1.5 wide; abdomen 3.6 long, 1.2 wide. Prosoma shape as in Fig. 9 View FIGURES 9 – 15 . Leg I: (11.3+0.7+11.7+20.3+2.8), tibia II: 7.5, tibia III: 5.2, tibia IV: 7.4; tibia I L/D: 53. Carapace short, broad and almost circular, ochre, with brown marks broadly connecting to ocular area. Cephalic region raised, with brown central marks, ocular area dark yellow. Clypeus 0.43, ochre, with several brown small dots. Each eye triad on the top of a relatively longer eye-stalk. Distance AME–AME 0.05, PME–PME 0.55. Diameter AME 0.06, ALE 0.16, PME 0.19, PLE 0.19. Chelicerae shape as in Fig. 10 View FIGURES 9 – 15 , with pair of black distal apophyses, pair of unsclerotized nipple-shaped small apophyses proximolaterally and pair of sclerotized small rounded apophyses proximocentrally. Labium and endites light yellow. Sternum dark gray, with yellow small patches. Legs ochre, femora, patellae and tibiae without dark rings. Tarsal organ of tarsus 1 capsulate. Abdomen cylindrical, pale ochre, dorsum with small brown patterns as in Fig. 9 View FIGURES 9 – 15 . Venter pale brown. Palps as in Figs. 12 and 13 View FIGURES 9 – 15 , femur with a dorsal projection retrolaterally; tibia spindle-shaped, with a triangular projection ventrally; bulb with nearly earshaped, flat, sclerotized uncus; short appendix with a large triangular central process prolaterally; embolus between the uncus and appendix, long and transparent, with a brush-shaped pointed tip; procursus complex, with a nearly triangular process.
Female: in general very similar to male. Paratype total length 5.4: cephalothorax 1.4 long, 1.5 wide; abdomen 4.0 long, 1.5 wide. Tibia I: Missing. Distance AME–AME 0.05, PME–PME 0.24. Diameter AME 0.08, ALE 0.15, PME 0.14, PLE 0.14. Epigynum roughly round as in Fig. 14 View FIGURES 9 – 15 , with a small teat-shaped apophysis. Dorsal view as in Fig. 15 View FIGURES 9 – 15 , with a rainbow-shaped sclerotized arch anteriorly and a pair of long oval pore plates.
