Type material. Holotype: male, Xiushui Cave [23º34.084'N, 107º40.777'E, 285 m, T: 24°C, H: 90%], Bafeng Mountain , Pinguo County, Baise City , Guangxi Zhuang Autonomous Region, China, 3 August 2009, C. Wang & Z. Yao leg. GoogleMaps Paratypes: 16 males, 33 females, same data as holotype GoogleMaps .

Etymology. The specific name refers to the type locality; adjective.

Diagnosis. This new species is similar to the generotype P. bailongensis , but can be distinguished by lack of the eyes and whitish opisthosoma (six eyes, blue opisthosoma in P. bailongensis ) ( Figs 9A View FIGURE 9 , 10A View FIGURE 10 ); embolus about 1.4 times longer than tegulum ( Figs 9C–D View FIGURE 9 , 11A–B View FIGURE 11 ) (embolus as long as tegulum in P. bailongensis ); and in the female epigynum with a row of short, slender setae behind epigastric furrow, spermatheca tenuous, ribbon-shaped ( Figs 10C–D View FIGURE 10 , 12C–E View FIGURE 12 ) (epigynum with a row of short, strong spines behind epigastric furrow, spermatheca strong, tube-shaped in P. bailongensis ).

Description. Male (holotype). Total length 1.50 ( Fig. 9A View FIGURE 9 ). Carapace 0.62 long, 0.62 wide. Opisthosoma 0.87 long, 0.75 wide. Sternum 0.35 long, 0.32 wide. Carapace, sternum, legs and chelicerae yellowish; labium and endites yellow. Eye absent. Leg measurements: I 5.99 (1.75, 0.20, 1.87, 1.37, 0.80); II 5.25 (1.50, 0.20, 1.60, 1.20, 0.75); III 3.95 (1.25, 0.15, 1.25, 0.75, 0.55); IV 4.92 (1.60, 0.20, 1.37, 1.00, 0.75). Opisthosoma whitish, circular dorsally. Palp measurements: 1.08 (0.23, 0.10, 0.27, -, 0.48). Palp tarsus ( Figs 9B–D View FIGURE 9 , 11A–B View FIGURE 11 , 12A View FIGURE 12 ): bulb about 1.3 times the length of tarsus, length about 3.0 times longer than wide, embolus long, tube-shaped, approximately 1.4 times longer than tegulum.

Female. Similar to male in coloration and general features, but with a larger body size and shorter legs. Total length 1.62 ( Figs 10A–B View FIGURE 10 ). Carapace 0.62 long, 0.60 wide. Opisthosoma 0.87 long, 0.87 wide. Sternum 0.40 long, 0.34 wide. Leg measurements: I 5.60 (1.75, 0.20, 1.70, 1.25, 0.70); II 5.20 (1.60, 0.20, 1.55, 1.10, 0.75); III 3.55 (1.15, 0.15, 1.00, 0.70, 0.55); IV 4.60 (1.50, 0.20, 1.35, 0.95, 0.60). Epigynum ( Fig. 12B View FIGURE 12 ) with a row of short, slender setae behind epigastric furrow. Spermatheca ( Figs 10C–D View FIGURE 10 , 12C–E View FIGURE 12 ) tenuous, ribbon-shaped, distal part swollen and reflexed.

Variation. Total length: males 1.58–1.62 (n = 17), females (1.45–1.54) (n=33).

Distribution. Known only from the type locality in Guangxi, China ( Fig. 17 View FIGURE 17 ).
