Figures 13 View FIGURE 13 , 14 View FIGURE 14 , 24 View FIGURE 24

Type material. Holotype ♀ (SWUC-T-AM-14-01), CHINA, Sichuan, Nyagquka (Yajiang) County, Mage Valley , 30°01.219′N 100°58.861′E, 2954 m, 15.V.2019, L.Y. Wang, T. Yuan and P. Liu GoogleMaps . Paratypes: 4 ♀ (SWUC-T-AM-14- 02~05), with same data as holotype GoogleMaps .

Etymology. The specific name is derived from the type locality, adjective in apposition.

Diagnosis. The new species resembles T. gyaisiensis by having big and semicircle shape epigynal teeth and the anterior margin of the epigynal median lobe cleft ( Figs 13B, C View FIGURE 13 , 14B, C View FIGURE 14 ). T. nyagqukaensis sp. nov., however, differs from the latter by the following characters: both sides of the median lobe are strongly bulged towards epigynal center in T. nyagqukaensis sp. nov. ( Figs 13B View FIGURE 13 , 14B View FIGURE 14 ), whereas they are not bulged in T. gyaisiensis sp. nov.; the cleft median lobe; copulatory openings present ventro-mesally; fertilization ducts extending dorso-laterally in T. nyagqukaensis sp. nov., whereas extending vertically with epigastric furrow in T. gyaisiensis sp. nov. ( Figs 13B, C View FIGURE 13 , 14B, C View FIGURE 14 ).

Description. Female. Total length 6.86–8.26. Holotype ( Fig. 14A View FIGURE 14 ) total length 8.26. Carapace 3.83 long, 2.38 wide; opisthosoma 4.62 long, 3.39 wide. Eye size and interdistances: AME 0.09, ALE 0.20, PME 0.15, PLE 0.17; AME–AME 0.11, AME–ALE 0.15, PME–PME 0.19, PME–PLE 0.28, ALE–PLE 0.07. MOA 0.50 long, front width 0.32, base width 0.49. Clypeus height 0.18. Chelicerae with 4 promarginal and 3 retromarginal teeth. Leg measurements: I 9.74 (2.81, 3.33, 2.24, 1.36); II 7.73 (2.41, 2.57, 1.64, 1.11); III 7.07 (2.12, 2.52, 1.53, 0.90); IV 8.90 (2.66, 3.13, 1.98, 1.13).

Epigyne ( Figs 13B, C View FIGURE 13 , 14B, C View FIGURE 14 ) with a dentiform and cleft median lobe. Epigynal teeth thick and close to anterior retro-lateral margin of the median lobe. Copulatory ducts long, located posteriorly. Spermathecae reniform. Fertilization ducts extending dorso-laterally.

Male unknown.

Distribution. Known only from the type locality, Sichuan, China ( Fig. 24 View FIGURE 24 ).
