Figs 23–24

Material. Holotype Ψ ( SMF), China, Quinghai Prov., Bei Shan National Park, 120 km NE Xining, 2300–2700 m, 23.V.–8.VI.1996, leg. J. Martens. Paratypes: 1 Ψ, ( SMF), same locality and dates, leg. J. Martens.

Diagnosis. The new species can easily be recognised by the specific shape of the epigyne with the rounded scape/pseudoscape, and the small posterior median plate.

Etymology. The species name refers to the locality whence the type material of this species derives; adjective.

Description. Female. Total length––2.63. Carapace 1.15 long, 0.93 wide, brown. Chelicerae 0.60 long. Legs pale brown without median bands. Leg I, 6.27 long (1.50+0.33+1.43+1.63+1.38), IV––5.09 long (1.40+0.33+1.25+1.28+0.83). Chaetotaxy unclear: spines mostly abraded (it is only possible to state that the tibiae are with ventral spine(s), and each metatarsus is with a dorsal spine). TmI––0.19. Opisthosoma 1.80 long, 1.25 wide, dorsally pale with a grey, wedge­like, axial stripe and flanked spots connected to the stripe with thin bands. Epigyne ( Figs 23–24 ): Scape/pseudoscape rounded, posterior median plate small, poorly expressed.
