Types. Holotype ♀, CHINA, Hunan Prov.: Zhangjiajie Co., Wulingyuan district, Suoxiyu town , Wenfeng Vill. , 110.599815°E, 29.331437°N, 457 m, 22.IV.2016, leg. W. Liu et al. leg.

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

Diagnosis. Oilinyphia wenfengensis sp. n. resembles O. hengji in having the similar somatic morphology and epigyne ( Figs 180A–C , 181A, B ; Zhao & Li 2014, figs 71A–C), but can be differentiated by the posterior end of ventral plate relatively broad in O. wenfengensis sp. n. ( Figs 180A, B ; vs. narrow); spermathecae spaced by two diameters in O. wenfengensis sp. n. ( Figs 180A–C ; vs. spaced by half of diameters).

Description. Female (holotype, Figs 181A, B ): Total length: 1.68. Carapace 0.65 long, 0.51 wide, dark brown, round posteriorly, the ocular region narrows, with long thick spines. Clypeus 0.18 high. Chelicerae with one promarginal and three retromarginal teeth. Sternum shield-like, black with microsetae. Eyes: AER recurved, PER slightly recurved. Eye sizes and interdistances:AME 0.05, ALE 0.05, PME 0.04, PLE 0.06, AME–AME 0.02, PME–PME 0.04, AME–ALE, 0.03, PME–PLE 0.05, AME–PME 0.06, ALE–ALE 0.26, PLE–PLE 0.28, ALE– PLE contiguous. Length of legs: I 1.92 (0.53, 0.62, 0.41, 0.36), II 1.87 (0.49, 0.59, 0.44, 0.35), III 1.51 (0.42, 0.46, 0.37, 0.26), IV 1.98 (0.55, 0.62, 0.48, 0.33). TmI 0.32 and TmIV 0.21. Tibial spine formula: 2-2-2-2. Opisthosoma 1.03 long, 0.87 wide, oval, blackish brown, adorned with ridges and papillae.

Epigyne ( Figs 180A–C ): Ventral plate (VP) wide, extended mesally with a truncated end, median extension of the ventral plate almost rectangular posteriorly; copulatory ducts (CD) short, simple; spermathecae (S) oval, present anterolaterally; fertilization ducts (FD) short, turning upwards.

Male. Unknown.

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