Type material.

Holotype ♂: Vietnam: Vinh Phuc Province: Dam Tao National Park: N21°27.62', E105°38.91', 999 m, leaf litter, 1.XI.2012, H.F. Zhao & Z.G. Chen leg. 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. huobaensis and P. yaosaensis by having a short, triangular embolus, but can be distinguished from them by a distinct brown spiral ridge (Figs 1B, 1D, 2 C–D) and droplet-shaped bulb (Figs 1 C–D, 2 A–B) vs. an indistinct spiral ridge of the embolus and an egg-shaped bulb in P. huobaensis and P. yaosaensis , as well as by a beak-shaped embolus (Figs 1B, 1D, 2D) vs. an equilateral triangular embolus in related species.
