Type material.

Holotype ♂: Vietnam: Bac Kan Province: Cho Don District: Pac Chan Cave, N22°22.78', E105°36.79', 225 m, 18.X.2012, H.F. Zhao & Z.G. Chen leg. Paratypes 2♂ and 5♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

This new species is similar to P. nuocnutensis sp. n. and P. podiensis , and can be distinguished from them by boomerang-shaped embolus (the embolus of P. nuocnutensis sp. n. is beak-shaped, embolus in P. podiensis is shaped like an isosceles triangle). The new species can be distinguished from other congeners by the medium length embolus (Figs 10 C–D, 11 A–B) (REC is 0.60) vs. REC of other Pinelema species 0.90 or less than 0.35.
