Type material. Holotype ♂: CHINA, Hubei Province, Jiugong Mountain, Yunzhong Lake , 29.40827913°N, 114.66505218°E, 1230 m, 30. VI.2020, matured on 17.IX.2020, Y. Zhong, Q.L. Lu, H. Dong & J.W. Zheng leg. (SWUC-T-AG-50-01) GoogleMaps ; Paratypes: 1 ♂ and 3 ♀, same data as holotype (SWUC-T-AG-50-02~05) GoogleMaps .
Etymology. The specific epithet refers to the type locality; adjective.
Diagnosis. The male of T. jiugongensis sp. nov. can be distinguished from all other congeners by the following characters: apex of conductor with two arms; the upper arm longer than wide and slightly grooved in ventral view; lower arm arc-shaped in retrolateral view ( Fig. 3B, C View FIGURE 3 ). Patellar apophysis almost C-shaped and extending 1/3 of above the tibia in retrolateral view ( Fig. 3C View FIGURE 3 ). The female resembles T. tautispinus ( Wang et al. 1990) in having similar atrial margins and the outline of epigyne ( Fig. 3D, E View FIGURE 3 ; Zhu et al. 2017, fig. 360A), but can be distinguished by the following characters: the distance between epigynal teeth seems C-shaped in T. jiugongensis sp. nov. ( Fig. 3D View FIGURE 3 ), vs. U-shaped in T. tautispinus ( Zhu et al. 2017, fig. 360A). Spermathecae pear-shaped in T. jiugongensis sp. nov. ( Fig. 3E View FIGURE 3 ), vs. globular in T. tautispinus ( Zhu et al. 2017, fig. 360B).

Palp ( Fig. 3A–C View FIGURE 3 ). Patella short; patellar apophysis long, almost C-shaped, extending above the 1/3 of the tibia in retrolateral view. Retrolateral and lateral tibial apophysis distinct with blunt end. Cymbium approximately 3 times longer than wide; cymbial furrow extensively sclerotized, about half of the cymbium length. Median apophysis spoon-like. Apex of conductor with two arms; the upper arm longer than wide and slightly grooved in ventral view; lower arm arc-shaped in retrolateral view. Conductor lamella indistinct. Conductor’s dorsal apophysis long, rodshaped with pointed end. Embolus filiform, originating at the 7 o’clock position.
Female (one of the paratypes, Fig. 9D View FIGURE 9 ). Total length 12.37. Carapace 6.78 long, 4.28 wide; opisthosoma 6.02 long, 3.88 wide. Eye sizes and interdistances: AME 0.21, ALE 0.31, PME 0.25, PLE 0.27; AME–AME 0.21, AME– ALE 0.18, PME–PME 0.19, PME–PLE 0.38, ALE–PLE 0.11. MOA 0.69 long, front width 0.62, back width 0.74. Clypeus height 0.23. Leg measurements: I 15.31 (4.45, 5.13, 3.52, 2.21); II 12.82 (3.82, 4.21, 2.96, 1.83); III 11.54 (3.29, 3.51, 3.08, 1.66); IV 16.27 (4.71, 5.41, 4.25, 1.90). Spination: legs: femur I 220, II 310, III 400, IV 210; patella I-IV 000; tibia I-II 026, III-IV 046; metatarsus I 045, II 046, III 066, IV 086.
Epigyne ( Fig. 3D, E View FIGURE 3 ). Epigynal plate longer than wide, teeth short and located anteriorly far from atrium, separated with narrow distance from each other. Atrial margin distinct, semicircular, posterior margin round. Epigynal hoods shallow, distinct, located ventro-mesally. Copulatory opening present dorso-laterally within atrium. Copulatory ducts short, tubular. Spermathecae pear-shaped, separated by a distance almost equal to their length.
Distribution. China (Hubei) ( Fig. 10 View FIGURE 10 ).
