Type material. Holotype male (SWUC-T-HY-03-01), China, Hubei Province, Shennongjia , 31°28′31″ N, 110°23′00″ E, elev. 1305 m, 24 October 2020, L.Y. Wang, Y. Zhang, J.X. Zhao and J.S. Luo leg. GoogleMaps Paratypes: 3 males and 6 females (SWUC-T-HY-03-02~10), with same data as holotype GoogleMaps .

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

Diagnosis. The male of this new species resembles E. pingwuensis sp. nov. ( Figs 9A–C View FIGURE 9 , 15E View FIGURE 15 , 16E View FIGURE 16 ), in having four strong setae on cymbial lobe retrolaterally, but differs from the latter by the narrow conductor, the arc-shapededge of the embolic base ( Figs 11A–C View FIGURE 11 , 15H View FIGURE 15 , 16H View FIGURE 16 ). The female of this new species resembles E. nyingchiensis sp. nov. ( Fig. 17E View FIGURE 17 ) in having the ventral spermathecae as long as dorsal spermathecae, but differs from the latter by the ball-shaped end of the dorsal spermathecae ( Fig. 18B View FIGURE 18 ).

Description. Male holotype ( Fig. 3B View FIGURE 3 ). Total length 13.45. Prosoma 6.22 long, 4.04 wide; Opisthosoma 7.23 long, 4.24 wide. Eye sizes and interdistances: AME 0.23, ALE 0.35, PME 0.42, PLE 0.36; AME–AME 0.19, AME– ALE 0.32, PME–PME 0.40, PME–PLE 0.15, ALE–PLE 0.12. MOA 0.66 long, front 0.65 wide, back width 1.03. Clypeus 0.33 high. Chelicerae with eight promarginal and ten retromarginal teeth. Leg measurements: I 72.03 (19.39, 23.04, 18.74, 10.86); II 59.20 (16.34, 19.16, 15.38, 8.32); III 44.18 (13.17, 14.22, 11.25, 5.54); IV 58.12 (16.79, 18.17, 15.46, 7.70). Leg formula: 1243.

Male palp ( Figs 11A–C View FIGURE 11 , 15H View FIGURE 15 , 16H View FIGURE 16 ). cymbium long, retrolaterally with a small semicircular lobe and a large one. Four strong setae originated from the large lobe. Embolus thin, length ratio of embolus to embolic base 1:1.5, basely grooved. Conductor long, sickle-shaped.

Female (One of paratypes, Fig. 3C View FIGURE 3 ) total length 17.97. Prosoma 7.79 long, 4.95 wide; opisthosoma 10.26 long, 6.36 wide. Eye sizes and interdistances: AME 0.24, ALE 0.38, PME 0.46, PLE 0.41; AME–AME 0.26, AME– ALE 0.46, PME–PME 0.50, PME–PLE 0.27, ALE–PLE 0.15. MOA 0.75 long, front 0.71 wide, back width 1.23. Clypeus 0.52 high. Leg measurements: I 59.26 (16.55, 20.66, 14.52, 7.53); II 51.22 (14.53, 17.35, 12.76, 6.58); III 37.58 (11.36, 12.85, 9.24, 4.13); IV 47.38 (14.12, 15.49, 12.04, 5.73). Leg formula: 1243.

Female genitalia ( Fig. 18B View FIGURE 18 ) with two pairs of strong and long spermathecae. Ventral spermathecae as long as dorsal spermathecae, apical end of dorsal spermathecae ball-shaped.

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