Epeus bicuspidatus: Peng et al. 1993: 48 , figs 121–124; Song et al. 1999: 508, figs 291N–O; Peng & Li 2002: 386, figs 1A–D; Yin et al. 2012: 1352, figs 732a–d.

Material examined. CHINA: Guizhou: Mt. Fanjin: 1 ♂ and 1 ♀, Experimental Plot of Heiwan River, 27°51′12.6″N, 108°45′52.2″E, Alt. 623m, 11.VII.2012, D. Wang & X.K. Jiang (SWUC-GZFJS-12-14); 1 ♀, near Heiwan River, 27°50′48″N, 108°46′17.4″E, Alt. 588m, 19.VII.2013, L.Y. Wang, X.K. Jiang & T. Lu (SWUC-GZFJS-13-04); 1 ♂ and 1 ♀, Botanical Garden, 27°49′50.4″N, 108°45′45.5″E, Alt. 516m, 26.VII.2013, L.Y. Wang, X.K. Jiang & T. Lu (SWUC- GZFJS-13-16).

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 ).
