Material examined. 1 male and 1 female, China, Qinghai Province, Huangyuan County, 10 September 1983, Z.S. Li leg. ; 12 females, Huangyuan County, 36°40′50″ N, 101°15′37″ E, elev. 2620 m, 26 July 2018, L.Y. Wang and Y.N. Mu leg.

Diagnosis. Male of this species resembles E. rulai Lin & Li, 2021 ( Figs 10A–C , 15F–G , 16F–G ) in having two strong setae on cymbial lobe, but differs from the latter by the short embolic base and the thin conductor ( Figs 7A–C , 15C , 16C ). Female of this species resembles E. yukuni Lin & Li, 2021 ( Fig. 18F ) in having two pairs of spermathecae, and ventral spermathecae two times longer than dorsal spermathecae, but differs from the latter by the strong ventral spermathecae ( Fig. 17D ).

Description. See Forster, Platnick & Gray (1987) as E. davidi . Habitus, male palp and female genitalia as in Figs 1F , 7A–C , 15C , 16C , 17D .
