Etymology. The specific epithet is derived from the type locality; adjective.

Diagnosis. Yuelushannus wenfengensis sp. n. resembles Y. jinyuanensis sp. n. in having the similar spermathecae and copulatory ducts ( Figs 305A–C View FIGURE 305 ; Figs 303A–C View FIGURE 303 ), but can be distinguished by the dorsal plate wider than long posteriorly in Y. wenfengensis sp. n. ( Figs 305A–C View FIGURE 305 ), vs., longer than wide in Y. jinyuanensis sp. n. ( Figs 303A–C View FIGURE 303 ); spermathecae touches the posterior margin of the epigynal plate in Y. wenfengensis sp. n. ( Figs 305A–C View FIGURE 305 ), vs., not touches the posterior margin of the epigynal plate in Y. jinyuanensis sp. n. ( Figs 303A– C View FIGURE 303 ).

Description. Female ( Figs 306A, B View FIGURE 306 ). Total length: 2.14. Carapace 0.86 long, 0.72 wide, cephalic region slightly elevated, yellow, cervical, fovea and radial grooves distinct. Clypeus 0.22 high. Chelicerae with five promarginal and six retromarginal teeth. Sternum longer than wide, brownisg grey with microsetae. Eyes: AER recurved, PER procurved, slightly wider. Eye sizes and interdistances: AME 0.04, ALE 0.07, PME 0.07, PLE 0.07, AME–AME 0.03, PME–PME 0.04, AME–ALE, 0.02, PME–PLE 0.04, AME–PME 0.07, ALE–ALE 0.28, PLE–PLE 0.30, ALE–PLE contiguous. Length of legs: I 2.16 (0.67, 0.73, 0.45, 0.31), II 2.11 (0.63, 0.76, 0.43, 0.24), III 1.8 (0.54, 0.61, 0.41, 0.24), IV 2.51 (0.67, 0.91, 0.66, 0.27). TmI 0.23, TmIV present. Tibial spine formula: 2-2-1-1. Opisthosoma 1.56 long, 1.08 wide, oval, grey, anteriorly with two pairs of sigillae, with irregular patches, densely covered with fine setae; ventral side grey.

Epigyne ( Figs 305A–C View FIGURE 305 ): Ventral plate (VP) sclerotized, wider than long, complete covering the dorsal plate (DP); copulatory openings (CO) present in the atrium between the ventral and dorsal plate. Dorsal plate (DP) wider than long posteriorly; copulatory ducts (CD) form spiral loop before joining the spermathecae; spermathecae (S) round, present posterio-lateraly on the dorsal plate and touches the posterior margin of the epigynal plate, pointing away from each other; fertilization ducts (FD) extending mesally.

Male. Unknown.

Distribution. Known only from the type locality (Hunan Province, Fig. 315 View FIGURE 315 ).
