Diagnosis. Males of this species are similar to E. guangxi (Peng & Li 2002: 388, figs 3A–D) in having the cymbial setae and retrolaterally located tegular apophysis, but can be distinguished by the bifid cymbial apophysis and the relatively sharp tegular apophysis (Figs 9–10). Females are similar to E. alboguttatus (Chen & Zhang 1991: 316, figs 336, 1–5) in having a trapezoid, shallow depression on the anterior half of epigyne, but can be distinguished by the relatively small copulatory openings, the thin, long and strongly coiled copulatory ducts (Figs 11–14).
