Type material. Holotype ♀ (SWUC-T-AM-13-01), CHINA, Sichuan, Gyaisi (Jiulong) County, 29°00.323′N 101°30.324′E, 2899 m, 1.VI.2019, L.Y. Wang, T. Yuan and P. Liu GoogleMaps . Paratypes: 3 ♀ (SWUC-T-AM-13-02~04), with same data as holotype GoogleMaps .

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

Diagnosis. The new species differs from all other Taira species by the following characters: epigynal teeth large and earlobe-shaped, covering most of the lateral portion of epigynal median lobe ( Figs 7A View FIGURE 7 , 8B View FIGURE 8 ); and distance between two spermathecae less than the diameter of the spermathecae ( Figs 7B View FIGURE 7 , 8C View FIGURE 8 ).
