Type material. Holotype: male, Fengwei Cave [24º20.163'N, 104º17.172'E, 1314 m, T: 19°C, H: 80%], Fengwei, Shuanglongying Town, Qiubei County, Wenshan Zhuang and Miao Autonomous Prefecture, Yunnan Province, China, 20 August, 2010, Z. Yao, C. Wang & X. Wang leg. Paratypes: 1 male, 3 females, same data as holotype .

Etymology. The specific name is a patronym in honor of Prof. Dr. Srećko Ćurčić, a well known biospeleologist from Belgrade, Serbia; noun (name) in genitive case.

Diagnosis. This new species is similar to the P. bailongensis , but can be distinguished by the pear-shaped bulb ( Figs 1C–D , 3A–B ) (oval in P. bailongensis ); the distal part of embolus not sclerotized ( Figs 1B , 4C ) (weakly sclerotized in P. bailongensis ); and in the female epigynum with a row of short, slender setae behind epigastric furrow, the distal part of spermatheca slender ( Figs 2C , 4E ) (epigynum with a row of short, strong spines behind epigastric furrow, distal part of spermatheca swollen in P. bailongensis ).

Description. Male (holotype). Total length 1.36 ( Fig. 1A ). Carapace 0.56 long, 0.55 wide. Opisthosoma 0.76 long, 0.60 wide. Sternum 0.32 long, 0.32 wide. Carapace, labium, endites and chelicerae, yellow; sternum brown. Carapace with a pair of setae at the retrolateral side of eyes. Leg measurements: I 4.17 (1.25, 0.15, 1.30, 0.87, 0.60); II 3.51 (1.12, 0.15, 1.05, 0.72, 0.47); III 2.34 (0.75, 0.12, 0.62, 0.45, 0.40); IV 3.00 (1.05, 0.15, 0.80, 0.60, 0.40). Opisthosoma blue, oval dorsally. Palp measurement: 0.81 (0.20, 0.09, 0.16, -, 0.36). Palp tarsus ( Figs 1B–D , 3A–B , 4C ): bulb pear-shaped, about 1.3 times longer than cymbium, about 2 times longer than wide; embolus tube-shaped, approximately as long as tegulum.

Female. Similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 0.80 ( Figs 2A–B ). Carapace 0.60 long, 0.55 wide. Opisthosoma 0.74 long, 0.56 wide. Sternum 0.34 long, 0.32 wide. Leg measurements: I 3.42 (1.12, 0.15, 0.90, 0.70, 0.55); II 3.02 (0.95, 0.15, 0.87, 0.55, 0.50); III 2.14 (0.75, 0.12, 0.55, 0.37, 0.35); IV 2.80 (1.00, 0.15, 0.75, 0.50, 0.40). Epigynum ( Fig. 4B ) with a row of short, slender setae posterior to epigastric furrow. Spermatheca ( Figs 2C , 4E ) elongate, cylindrical, distal part bent ventrally.

Variation. Total length: males 1.34–1.36 (n = 2), females 0.78–0.81 (n=3).

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