Type material: Holotype male, CHINA: Hebei Province, Zhangjiakou City, Chicheng County, Dahaituo National Natural Reserve (40°34.933´N, 115°46.066´E), 5 November 2005, Q. Wang, Y. Song & G. Zheng leg. Paratypes: 18 males and 10 females, same data as for holotype.
Etymology: The species name is a noun in apposition derived from the type locality.
Diagnosis: The new species is similar to P. pennatus Zhang, Zhu & Song, 2005, but can be distinguished by the shapes of bulbal appendix and procursus, and the chitinized triangular plate of the epigynum.
Description: Male (holotype). Total length 5.28 (5.84 with clypeus), carapace width 1.76. Leg 1: 48.28 (12.42+0.71+12.71+19.85+2.59), tibia 2: 8.28, tibia 3: 5.57, tibia 4: 7.71; tibia 1 L/d: 68. Habitus as in figs 1D, E. Carapace yellowish, with brown radiated stripes and brown marginal band; ocular area yellowish, with brown band at median and laterally; clypeus yellowish, without marks; sternum deep yellow. Opisthosoma gray, with some spots dorsally and laterally. Distance PME–PME 0.27; diameter PME 0.15; distance PME– ALE 0.06; diameter AME 0.09. Chelicerae as in figs 4C, D, with pair of black apophyses distally, pair of unsclerotized apophyses proximolaterally, and pair of finger-shaped prominences frontally.
