Type material. Holotype ♂: CHINA, Chongqing City, Jinyun Mountain, Guankou, 29.839486°N, 106.388354°E, 650 m, 24.X.2011, L.Y. Wang, D. Wang & M.X. Liu leg. (SWUC-T-AG-49-01); Paratypes (4 ♂ and 8 ♀): 2 ♀, same data as holotype (SWUC-T-AG-49-02~03); 1 ♀, Gele Mountain Forest Park, 29.573881°N, 106.434339°E, 728 m, 14.IV.2011, L.Y. Wang & Z.X. Li leg. (SWUC-T-AG-49-04); 4 ♂ and 5 ♀, Beibei District, Jindaoxia Valley, 30.028285°N, 106.624741°E, 880 m, 23.XI.2008, Z.S. Zhang leg (SWUC-T-AG-49-05~13).
Etymology. The specific epithet refers to the type locality; adjective.
Diagnosis. Males of this new species resemble those of T. rostrum (Jiang et al. 2018) in having similar tegular sclerites, conductor’s dorsal apophysis and tibial apophysis, but can be distinguished by the following characters: the apex of the conductor slightly curved, narrowing towards tip with a blunt end in ventral view (Fig. 2B, C), vs. apex bifurcated with pointed end (Jiang et al. 2018, fig. 23A); ventral margin of median apophysis wider than long in retrolateral view (Fig. 2B, C), vs. longer than wide (Jiang et al. 2018, fig. 23B); the anterior margin of conductor lamella round in ventral view (Fig. 2B), vs. protruding laterally with a blunt tip (Jiang et al. 2018, fig. 23A); the patellar apophysis extends to the ventral side of the tibia in retrolateral view (Fig. 2C), vs. extending above the tibia (Jiang et al. 2018, fig. 23B). Female of the new species can be distinguished from all other congeners by the following characters: anterior and lateral margins of atria somewhat rectangular, narrowing posteriorly, epigynal teeth absent; spermathecae human brain-shaped and the copulatory ducts long and indistinct (Fig. 2D, E).
Description. Male (holotype, Fig. 9A). Total length 15.65. Carapace 8.27 long, 4.92 wide; opisthosoma 7.01 long, 4.07 wide. Eye sizes and interdistances: AME 0.23, ALE 0.31, PME 0.26, PLE 0.33; AME–AME 0.23, AME– ALE 0.15, PME–PME 0.18, PME–PLE 0.40, ALE–PLE 0.14. MOA 0.81 long, front width 0.69, back width 0.75. Clypeus height 0.35. Leg measurements: I 21.43 (5.67, 6.69, 5.39, 3.68); II 18.80 (5.04, 5.99, 4.62, 3.15); III 16.89 (4.63, 5.04, 4.51, 2.71); IV 22.38 (5.79, 7.05, 6.39, 3.15).

Palp (Fig. 2A–C). Patella short, patellar apophysis longer than patella, slightly curved with pointed end, extending forward. Tibia with retrolateral and lateral apophyses with blunt tips. Cymbium approximately 3 times longer than wide; cymbial furrow extensively sclerotized, 1/3 of cymbium length. Median apophysis spoon-like. Conductor sclerotized, longer than wide, slightly curved in ventral view, distal end beak-shaped in ventral view. Conductor lamella conspicuous with round margin, conductor’s dorsal apophysis long, rod-shaped with pointed end. Embolus filiform, originating at the 7 o’clock position.
Female (one of the paratypes from Jinyun Mt., Fig. 9B). Total length 16.05. Carapace 8.25 long, 4.86 wide; opisthosoma 8.28 long, 5.66 wide. Eye sizes and interdistances: AME 0.24, ALE 0.32, PME 0.32, PLE 0.30; AME– AME 0.21, AME–ALE 0.14, PME–PME 0.20, PME–PLE 0.44, ALE–PLE 0.15. MOA 0.80 long, front width 0.65, back width 0.75.

Spination of legs: femur I-II 220, III 140, IV 210; patella I-II 000, III-IV 020; tibia I 016, II 026, III-IV 046; metatarsus I 006, II 046, III 096, IV 086.
Epigyne (Fig. 2D, E). Epigynal plate somewhat rectangular, teeth absent. Atrial margins distinct, narrowing posteriorly. Epigynal hoods shallow, indistinct, located ventro-mesally. Copulatory opening located in anterior margin of epigynal plate. Copulatory ducts long, indistinct. Spermathecae human brain-shaped, separated by less than 1/3 of their width.
Distribution. China (Chongqing) (Fig. 10).
