Etymology. The species name is a noun in apposition derived from the Chinese pinyin "dazhonghua" (Greater China) and refers to the species distribution.

Diagnosis. The males of this species can be distinguished from others by having a short, strong embolus, a sheet-shaped median apophysis, terminus with hook, while the females can be distinguished by the epigyne with the width being greater than the length, two hoods anteriorly, copulatory ducts indistinct, secondary spermathecae folded with copulatory ducts.

Description. Male (IZCAS-Ar39705). Total length 6.34, carapace 3.84 long, 2.59 wide, opisthosoma 3.80 long, 3.68 wide. Eye sizes and interdistances: AME 0.14, ALE 0.16, PME 0.22, PLE 0.25, AME–AME 0.09, AME–ALE 0.06, PME– PME 0.21, PME–PLE 0.26, AME–PME 0.08, ALE–PLE 0.23. Clypeus height 0.09. Chelicerae with three promarginal and one or two retromarginal teeth. Leg measurements: leg I: 9.49 (3.32 + 3.24 + 2.02 + 0.91), leg II: 14.26 (4.60 + 5.19 + 3.32 + 1.15), leg III: 13.60 (4.40 + 4.90 + 3.22 + 1.08), leg IV: 10.89 (3.76 + 3.56 + 2.62 + 0.95). Leg formula: 2341.

Male palp ( Figs 2 View Figure 2 C–D, 8B). Retrolateral tibial apophysis absent. Cymbium oval, sub-tegulum brown, hidden under tegulum and embolus. Tegulum irregularly shaped, with prolateral angular protrusion, median apophysis sheet-shaped, terminus with hook. embolus short, robust, conical, without obvious apophysis. Conductor membranous, triangular, originating between median apophysis and embolic base.

Female (IZCAS-Ar39709). Total length 10.38, carapace 3.68 long, 5.58 wide, opisthosoma 6.54 long, 6.41 wide. Eye sizes and interdistances: AME 0.14, ALE 0.18, PME 0.14, PLE 0.28, AME–AME 0.15, AME–ALE 0.19, PME–PME 0.33, PME–PLE 0.46, AME–PME 0.18, ALE–PLE 0.36. Clypeus height 0.11. Chelicerae with five promarginal and two retromarginal teeth. Leg measurements: Leg I: 13.01 (4.90 + 4.70 + 2.25 + 1.16), leg II: 19.61 (6.86 + 7.18 + 4.12 + 1.45), leg III: 19.03 (6.54 + 6.86 + 4.30 + 1.33), leg IV: 15.55 (5.64 + 5.05 + 3.72 + 1.14). Leg formula: 2341.

Epigyne ( Figs 2 View Figure 2 A–B) width greater than length, two hoods anteriorly. Copulatory ducts indistinct. Secondary spermathecae close to copulatory openings, spermathecal head obvious. Primary spermathecae posterior, oval, posterior to secondary spermathecae, primary spermathecal head obvious.

Distribution. Known only from the type locality.
