Etymology. The specific epithet is derived from the type locality; adjective.
Diagnosis. Gongylidium mangshanensis sp. n. resembles G. serratus in having the similar wave-like posterior margin of ventral plate and spermathecae (Figs 103A–D; Irfan et al. 2022, figs 126A–C), but can be distinguished by the dorsal plate funnel-shaped in G. mangshanensis sp. n. (Fig. 103D; vs. rectangular).
Description. Female (holotype, Figs 104A, B): Total length: 2.83. Carapace 1.09 long, 0.92 wide, yellowish brown, cervical and radial grooves distinct. Clypeus 0.19 high. Chelicerae sclerotized, dark brown, with five promarginal and five retromarginal teeth. Sternum shield-like, yellowish brown with microsetae. Eyes: AER recurved, PER straight, slightly wider than AER. Eye sizes and interdistances: AME 0.05, ALE 0.08, PME 0.06, PLE 0.07, AME–AME 0.03, PME–PME 0.06, AME–ALE, 0.02, PME–PLE 0.05, AME–PME 0.04, ALE–ALE 0.31, PLE–PLE 0.35, ALE–PLE contiguous. Length of legs: I 5.34 (1.51, 1.81, 1.34, 0.68), II 5.07 (1.43, 1.69, 1.32, 0.63), III 3.5 (1.07, 1.05, 0.92, 0.46), IV 4.52 (1.31, 1.41, 1.23, 0.57). TmI and TmIV present. Tibial spine formula: 2-2-1-1. Opisthosoma 1.74 long, 1.05 wide, oval, pale, mid dorsally with longitudinal greenish band anteriorly followed by 3 transverse chevrons, ventral side pale.
Epigyne (Figs 103A–D): Ventral plate (VP) longer than wide protruding above the epigastric furrow posteriorly, posterior margin wave-like. Copulatory opening (CO) present dorsally at the posterior margin of the ventral plate. Dorsal plate (DP) longer tha wide, fused with ventral plate posteriorly; copulatory ducts (CD) present mesally, forming a spiral coiled loop, before joining the spermathecae, extending above the spermathecae anteriorly; spermathecae (S) globular, present anterolaterally, spaced by 2/3 of diameters; fertilization ducts (FD) small, extending mesally.
Male. Unknown.
Distribution. Known only from the type localities (Hunan Provinces, Fig. 315).
