Type material. Holotype male (SWUC-T-HY-01-01), China, Tibet, Nyingchi City, Lulang Town , 29°49′08′′ N, 94°44′23′′ E, elev. 3087 m, 8 August 2020, L.Y. Wang, T. Yuan & Y.M. Hou leg. GoogleMaps Paratypes: 7 females (SWUC-T- HY-01-02~08), with same data as holotype GoogleMaps .
Etymology. The specific name is derived from the type locality; noun in apposition.
Diagnosis. The new species resembles E. yukuni Lin & Li, 2021 ( Figs 14A–C View FIGURE 14 , 15K View FIGURE 15 , 16K View FIGURE 16 , 18F View FIGURE 18 ) in having five strong setae on cymbial lobe and two pairs of spermathecae, but differs from the latter by the wide and short conductor base, the right-angled lower edge of the embolic base ( Figs 8A–C View FIGURE 8 , 15D View FIGURE 15 , 16D View FIGURE 16 ), the short ventral spermathecae ( Fig. 17E View FIGURE 17 ).

Male palp ( Figs 8A–C View FIGURE 8 , 15D View FIGURE 15 , 16D View FIGURE 16 ). Cymbium long, retrolaterally with a small semicircular lobe and a large lobe bearing five strong setae. Embolus thin, its length slightly shorter than embolic base, basaly grooved. Conductor wide, sickle-shaped.
Female (One of paratypes). Total length 19.41. Prosoma 7.95 long, 4.81 wide; opisthosoma 10.94 long, 8.14 wide.

Leg formula: 1243.
Female genitalia ( Fig. 17E View FIGURE 17 ), with two pairs of spermathecae. Dorsal spermathecae small and short, longer than the half length of ventral spermathecae. Ventral spermathecae slight curved, whit a narrow base
Distribution. Known only from the type locality, Tibet, China ( Fig. 19 View FIGURE 19 ).
