Figures 12A–B , 13A–C , 14

Type material. Holotype male, Xinjiang, Shihezi City , Manasi County, 44°18.091′N, 86°12.890′E, elev. 470 m, August 2015, J. Su & T. Li leg. (SWUC-T-LY-13-01).

Etymology. The specific name comes from the type locality.

Diagnosis. Male of this new species resembles X. mongolica ( Figs 6A–B , 7C–G , 8A–E ), but differs from the latter by the slightly branched terminal apophysis and median apophysis larger and with a long, cuspidal ventral process ( Figs 12A–B , 13B–C ).

Description. Male holotype ( Fig. 13A ) total length 6.43. Carapace 3.60 long, 2.35 wide; opisthosoma 2.58 long, 1.92 wide. Carapace yellow brown. Eye sizes and interdistances: AME 0.15, ALE 0.10, PME 0.37, PLE 0.32; AME–AME 0.08, AME–ALE 0.05, PME–PME 0.29, PME–PLE 0.39. Clypeus height 0.09. Chelicerae, labium, endites and sternum yellow brown. Sternum with sparse brown setae. Leg measurements: I 10.61 (3.15, 3.33, 2.64, 1.49); II 7.65 (2.25, 2.39, 1.82, 1.19); III 10.95 (3.13, 3.15, 3.06, 1.61); IV 13.58 (3.81, 4.07, 3.88, 1.82). Leg formula: 4312. Opisthosoma oval. Dorsum yellow brown, with black mark, cardiac mark dark brown. Venter yellow brown.

Male pedipalp ( Figs 12A–B , 13B–C ). Subtegulum baso-prolaterally located. Terminal apophysis membranous, wide and with a somewhat bifurcate tip. Embolus long. Conductor small and membranous, with a rounded end. Median apophysis strong, with an axe-like ventral process.

Female unknown.

Distribution. Known only from the type locality in Xinjiang, China ( Fig. 14 ).
