Type material. Holotype: male, Huoba Cave [24º08.308'N, 104º06.755'E, 1455 m, T: 21°C, H: 73%], Puzhehei , Shuanglongying Town, Qiubei County, Wenshan Zhuang and Miao Autonomous Prefecture, Yunnan Province, China, August 18 2009, Z. Yao, C. Wu & X. Wang leg. Paratypes: 1male, 1 female, same data as holotype .

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

Diagnosis. This new species can be distinguished from the generotype P. bailongensis by the lack of eyes and yellowish opisthosoma (six eyes, blue opisthosoma in P. bailongensis ) ( Figs 5A, 6A); embolus short, about 1/4 the length of the tegulum ( Figs 5C–D, 7A–B) (embolus as long as tegulum in P. bailongensis ); and in the female epigynum with a row of short, slender setae behind epigastric furrow ( Fig. 8A), spermatheca begins to be swollen at 1/3 point, contracted and not curving at the distal part ( Figs 6C, 8B–C) (epigynum with a row of short, strong spines behind epigastric furrow, spermatheca begins to be swollen at 4/5 point, curving ventrally at 3/5 point in P. bailongensis ).

Description. Male (holotype). Total length 1.80 ( Fig. 5A). Carapace 0.75 long, 0.62 wide. Opisthosoma 1.00 long, 0.87 wide. Sternum 0.35 long, 0.44 wide. Carapace, sternum, yellowish; legs, labium, endites and chelicerae yellow. Carapace with a pair of setae at the retrolateral side of eyes. Eye absent. Leg measurements: I 5.65 (1.65, 0.25, 1.75, 1.25, 0.75); II 4.95 (1.50, 0.25, 1.50, 1.00, 0.70); III 3.65 (1.15, 0.25, 0.95, 0.75, 0.55); IV 4.45 (1.40, 0.25, 1.25, 0.95, 0.60). Opisthosoma whitish, circular dorsally. Palp measurements: 0.92 (0.19, 0.10, 0.22, -, 0.41). Palp tarsus ( Figs 5B–D, 7A–C): bulb, oval, subequal to the length of tarsus, about 2.0 times longer than wide; embolus short, approximately 1/4 the length of the tegulum.

Female. Similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 1.80 ( Figs 6A–B). Carapace 0.80 long, 0.60 wide. Opisthosoma 0.90 long, 0.70 wide. Sternum 0.50 long, 0.40 wide. Leg measurements: I 5.92 (1.80, 0.25, 1.87, 1.25, 0.75); II 5.29 (1.62, 0.25, 1.62, 1.15, 0.65); III 3.70 (1.15, 0.25, 1.00, 0.75, 0.55); IV 4.77 (1.50, 0.25, 1.30, 1.10, 0.62). Epigynum ( Fig. 8A) with a row of short, slender setae behind epigastric furrow. Spermatheca ( Figs 6C, 8B–C) sacciform, begins to be swollen at 1/3 point and contracted at distal part.

Variation. Total length: males 1.76–1.80 (n = 2).

Distribution. Known only from the type locality in Yunnan, China ( Fig. 17)
