Type material.

Holotype ♂: China: Guangxi Zhuang Autonomous Region: Nanning Prefecture: Longan County: Cunfeng Cave, N23°12.58', E107°35.43', 115 m, 13.V.2015, Z. Chen & Y. Li. Paratypes: 3♂ and 5♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The new species is similar to P. podiensis sp. n., and can be distinguished by the well-developed eyes and greenish abdomen (Figs 1A, 2A) (eyes reduced to white spots, abdomen pale yellow in P. podiensis sp. n.); relatively shorter embolus (about 0.33 of bulbal length) (Figs 1 C–D, 7B, 8B, 9B, 10B) (0.38 of kidney shaped bulb in P. podiensis sp. n.); cymbial apophysis with 3 setae (Fig. 12B) (4 setae in P. podiensis sp. n.); receptacle slightly curved at anterior 1/3 (Fig. 2C) (almost straight in P. podiensis sp. n.).

Description.

Male (holotype): Total length 1.33. Carapace 0.50 long, 0.49 wide. Abdomen 0.79 long, 0.60 wide. Carapace dark yellow with purple-brown pattern (Fig. 1A). Six eyes, all well-developed, ringed with black. Chelicerae, legs, labium and endites dark yellow. Sternum dark brown, with sparse setae. Leg measurements: I 4.11 (1.18, 0.19, 1.33, 0.85, 0.56); II 3.59 (1.08, 0.19, 1.13, 0.69, 0.51); III 2.56 (0.81, 0.17, 0.75, 0.46, 0.36); IV 3.08 (0.99, 0.18, 0.92, 0.60, 0.38). Abdomen blue-green with purple-brown pattern ventrally.

Palp: tibia 2.5 times longer than patella, cymbium approximately two times longer than tibia, cymbial apophysis with 3 setae (Fig. 12B); bulb almost pear shaped (Figs 1 C–D, 7B, 8B, 9B, 10B), the spiral ridge makes a continues approximately 180° around the embolus (Figs 1B, 11B); tip of embolus with two grooves, embolus opening slit-like, with the slit originating from the tip and terminating mesally (Figs 8B, 10B).

Female: Total length 1.42. Carapace 0.48 long, 0.48 wide. Abdomen 0.87 long, 0.71 wide. Coloration and pattern as in male (Figs 2 A–B). Leg measurements: I 3.67 (1.08, 0.18, 1.15, 0.75, 0.51); II 3.08 (0.95, 0.16, 0.98, 0.61, 0.38); III 2.30 (0.69, 0.17, 0.65, 0.41, 0.38); IV 2.94 (0.92, 0.16, 0.89, 0.56, 0.41).
