Type material.

Holotype ♂: Vietnam: Quang Binh Province: Phong Nha-Ke Bang National Park: Tien Son Cave, N17°34.80', E106°16.92', 102 m, 17.V.2016, Z.G. Chen & Q.Y. Zhao leg. Paratypes 3♂ and 5♀, same data as holotype.

Etymology.

This specific name is derived from the Chinese Pinyin ‘xié zǐ’, meaning ‘shoe’, in reference to the shoe-shaped embolus; noun.

Diagnosis.

This new species is similar to P. huobaensis and P. yaosaensis by a having short embolus. It can be distinguished from related species by the shoe-shaped embolus (Figs 16B, 17 C–D) (vs. triangular embolus in related species). It is also similar to P. laensis sp. n. but can be distinguished by the unsclerotized margin of the embolus (the embolus of P. laensis sp. n. is sclerotized marginally and hollow). This new species can be distinguished from other congeners by the short embolus.
