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

Description. Female (Figs 306A, B). 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.

Epigyne (Figs 305A–C): 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).
