Etymology. The specific name is derived from the type locality; noun in apposition.

Diagnosis. The male of this new species resembles E. wukong Lin & Li, 2020 ( Figs 13A–C View FIGURE 13 , 15J View FIGURE 15 , 16J View FIGURE 16 ), in having three strong setae on cymbial lobe retrolaterally, but differs from the latter by the narrow conductor ( Figs 12A–C View FIGURE 12 , 15I View FIGURE 15 , 16I View FIGURE 16 ). The female of this new species resembles E. yukuni Lin & Li, 2021 ( Fig. 18F View FIGURE 18 ) in having two pairs of spermathecae, ventral spermathecae long and dorsal spermathecae short, but differs from the latter by the slightly thicker ventral spermathecae and longer dorsal spermathecae ( Fig. 18C View FIGURE 18 ).

Description. Male holotype ( Fig. 3D View FIGURE 3 ). Total length 13.17. Prosoma 6.26 long, 3.97 wide; Opisthosoma 6.83 long, 4.00 wide. Eye sizes and interdistances: AME 0.25, ALE 0.33, PME 0.31, PLE 0.37; AME–AME 0.20, AME– ALE 0.30, PME–PME 0.42, PME–PLE 0.21, ALE–PLE 0.08. MOA 0.62 long, front 0.61 wide, back width 0.94.

Clypeus 0.47 high. Chelicerae with eight promarginal and six retromarginal teeth. Leg measurements: I 57.61 (15.13, 18.61, 14.62, 9.25); II 49.45 (13.27, 16.05, 12.58, 7.55); III 38.00 (11.06, 12.35, 9.45, 5.14); IV 48.59 (13.91, 15.14, 12.82, 6.72). Leg formula: 1243.

Male palp ( Figs 12A–C View FIGURE 12 , 15I View FIGURE 15 , 16I View FIGURE 16 ). Cymbium long, retrolaterally with a small semicircular lobe and a large lobe bearing three setae (two strong, one thin). Embolus thin, length ratio of embolus to embolic base slightly longer, basely grooved. Conductor long, sickle-shaped.

Female (one of paratypes, Fig. 3F View FIGURE 3 ). Total length 16.26. Prosoma 6.68 long, 4.49 wide; opisthosoma 9.35 long, 7.76 wide. Eye sizes and interdistances: AME 0.24, ALE 0.36, PME 0.33, PLE 0.35; AME–AME 0.21, AME–ALE 0.34, PME–PME 0.42, PME–PLE 0.22, ALE–PLE 0.09. MOA 0.57 long, front 0.65 wide, back width 1.03. Clypeus 0.49 high. Leg measurements: I 42.69 (12.40, 15.13, 9.83, 5.33); II 38.26 (10.92, 12.57, 9.83, 4.94); III 28.55 (8.73, 9.48, 6.67, 3.67); IV 35.46 (10.44, 11.60, 8.79, 4.63). Leg formula: 1243.

Female genitalia ( Fig. 18C View FIGURE 18 ) with two pairs of spermathecae. Dorsal spermathecae small and short, ventral spermathecae arc-shaped and three times the length of dorsal spermathecae.

Distribution. Known only from the type locality, Sichuan, China ( Fig. 19 View FIGURE 19 ).
