Type material.

Holotype ♂ - VIETNAM: Ninh Binh Province, disturbed forest of Cuc Phuong National Park [20°17.066'N, 105°40.253'E, elevation 273 m], pitfall traps, March 1-30, 2008. Paratypes: 26♂ (IZCAS), same data as holotype.

Etymology.

The specific epithet, a Latinised adjective, refers to the type locality.

Diagnosis.

The new species shares with Sinopesa kumensis the complete absence of an abdominal pattern and the presence of a short male palpal tibia, but it can be distinguished from the latter species by the complete absence of PMS and by the presence of a globular bulb and of a gradually tapering and apically hooked embolus (oval and corkscrew-shaped, respectively) in Sinopesa kumensis (see Figs 20 A–C, 21 A–C, and Shimojana and Haupt 2000: figs. 3 A–B).
