Etymology.
The specific name refers to the type locality; adjective.
Diagnosis.
The new species is similar to
P. bailongensis
and can be distinguished by the completely reduced eyes and yellow abdomen (Figs 5A, 6A) (eyes well-developed and abdomen greenish in
P. bailongensis
); the shorter embolus, 0.40 of bulb length (Figs 5
C-D
, 7D, 8D, 9D, 10D) (0.59 of bulb length in
P. bailongensis
); receptacle curves approximately 450° (Fig. 6C) (receptacle curves approximately 540° in
P. bailongensis
) and cymbial apophysis with five setae (Fig. 12 D) (four setae in
P. bailongensis
).

Description.
Male (holotype): Total length 1.72. Carapace 0.71 long, 0.59 wide. Abdomen 1.00 long, 0.80 wide. Carapace yellow (Fig. 5A). Eyes entirely reduced. Chelicerae, legs, labium, and endites yellow. Sternum pale yellow. Leg measurements: I 6.53 (2.00, 0.25, 2.08, 1.44, 0.77); II 5.91 (1.76, 0.26, 1.90, 1.28, 0.71); III 4.23 (1.47, 0.23, 1.16, 0.84, 0.53); IV 4.60 (1.56, 0.23, 1.33, 0.92, 0.56). Abdomen pale yellow, with sparse long setae.
Palp: tibia 2.2 times longer than patella, tarsus 1.9 times longer than tibia, cymbial apophysis with five setae (Fig. 12D); bulb subconical; embolus long, tube shaped (Figs 5
C-D
, 7D, 8D, 9D, 10D); the spiral ridge makes a complete 360° turn around the embolus (Figs 5B, 11D), opening of embolus indistinct, as long as half length of embolus (Figs 8D, 10D).
Female: Total length 1.72. Carapace 0.65 long, 0.65 wide. Abdomen1.04 long, 0.89 wide. Coloration and pattern as in male (Figs 6
A-B
). Leg measurements: I 5.94 (2.13, 0.27, 2.13, 1.42, 0.75); II 5.23 (1.86, 0.26, 1.88, 1.24, 0.63); III 3.81 (1.41, 0.24, 1.31, 0.85, 0.51); IV 4.67 (1.72, 0.24, 1.60, 1.11, 0.59). Receptacle curved, 450° (Fig. 6C).
