Type material: Holotype ♀ (SWUC-T-AM-05-01) and 6 ♀ paratypes (SWUC-T-AM-05-02~07), CHINA, Guizhou, Weining County, Caohai Nature Reserve , 26°52.202′N 104°12.342′E, 2130 m, 2.VII.2005, H.M. Chen, ex- amined.

Material examined. Guizhou: 5 ♂ and 4 ♀, Caohai Nature Reserve, Minzu Village , 26°52.165′N 104°12.342′E, 2130 m, 17.V.2017, H.M. Chen, Z.S. Zhang and L.Y. Wang ( SWUC) ; 3 ♂, 1 ♀, Weining County, Xiaohai Town, Zhoujiashan , 26°56.04′N 104°09.52′ E, 2201 m, 20.V.2017, H.M. Chen, Z.S. Zhang and L.Y. Wang ( SWUC) ; 4 ♀, Weining County, Mt. Mabaida , 26°43.400′N 104°06.667′E, 2379 m, 21.VIII.2017, L.Y. Wang, Y.J. Lin and C.Y. Hu ( SWUC) .

Diagnosis. The male of this species can be differentiated from males of all other Taira species by having a hook-shaped median apophysis situated 90° to the tegulum ( Figs 9D, E , 10D, E ) and a hook-shaped embolus with a sharp pointed end ( Figs 9C , 10C ). The female of this species most closely resembles T. liboensis by having rounded spermathecae and a strip-shaped epigynal median lobe ( Figs 10F, G ), but can be distinguished by having the spermathecae separated at a distance more than three times their diameter.

Description. Male (firstly described). Total length 6.11–8.62. Male ( Fig. 10A ) total length 8.59. Carapace 4.30 long, 3.08 wide; opisthosoma 4.24 long, 2.78 wide. Eye size and interdistances: AME 0.18, ALE 0.22, PME 0.18, PLE 0.20; AME–AME 0.08, AME–ALE 0.13, PME–PME 0.26, PME–PLE 0.34, ALE–PLE 0.09. MOA 0.67 long, front width 0.44, base width 0.61. Clypeus height 0.23. Chelicerae with 4 promarginal and 3 retromarginal teeth. Leg measurements: I 20.62 (5.45, 7.04, 5.43, 2.70); II 15.10 (4.47, 5.03, 3.63, 1.97); III 12.42 (3.59, 4.11, 3.06, 1.66); IV 15.33 (4.51, 5.17, 3.90, 1.75).

Male palp ( Figs 9C–E , 10C–E ). Retrolateral tibial apophysis absent. Dorsal tibial apophysis inflated, concave, bowl-like; interior branch of dorsal tibial apophysis leaf-shaped with a small process located near base of dorsal tibial apophysis in prolateral view. Exterior branch of dorsal tibial apophysis depressed in prolateral view. Embolus hook-shaped, with sharp pointed end. Median apophysis hook-shaped, situated 90° to tegulum. Tegular apophysis reduced, triangle-shaped.

Female ( Fig. 10B ), description see Zhang et al. (2008). Epigyne ( Figs 9A, B , 10F, G , 11A, B ).

Distribution. China (Guizhou) ( Fig. 24 ).
