Type material.
Holotype ♂ (IZCAS): China, Guangxi Zhuang Autonomous Region, Hechi Prefecture, Nandan County, Lihu Town, Wangshang Village, Wangshang Cave,
25°05.300'N
,
107°38.420'E
, 602 m, 1.II.2015, Y. Li and Z. Chen leg. Paratypes (IZCAS): 4♂ and 5♀, same data as holotype.
Other material examined.
4♀ (molecular vouchers, IZCAS), same data as holotype.
Etymology.
The species epithet refers to the type locality; noun.
Diagnosis.
This species resembles
P. yunchuni
Zhao & Li, sp. n. (Figs 25-27) but can be distinguished by following characters: bulb kidney-shaped (Figs 18A, B, 19C, D) (bulb pear-shaped in
P. yunchuni
Zhao & Li, sp. n.), curved dorso-medially (Figs 18A, B, 19C, D) (bulb not curved dorso-medially in
P. yunchuni
Zhao & Li, sp. n.), smaller El/Bl ratio (1.37-1.45, n = 5, mean: 1.41, Suppl. material 1: Figure S8) (larger El/Bl ratio 1.78-1.82, n = 4, mean: 1.80 in
P. yunchuni
Zhao & Li, sp. n.), and receptacle J-shaped (Figure 20C) (receptacle U-shaped in
P. yunchuni
Zhao & Li, sp. n.).
