243E11C8179A5B4486D2DB38C8F5637A.taxon	diagnosis	Diagnosis. Males are similar to E. baoshanensis Liu et al. (2019) but can be distinguished from them by the palpal structure: 1) embolus extends along the left lower lateral aspect of the genital bulb to the posterior margins, but the embolus mainly encircles the left upper lateral and anterior margins of the bulb in E. baoshanensis (Figs 2 C, D, 3 A, B); 2) conductor with a sharp tip in ventral view and not bifurcated, but conductor sclerotized and tip bifurcated in E. baoshanensis (Figs 2 C, 3 A). Females are similar to E. nubilus but can be distinguished from them by the direction of the copulatory duct: fertilization ducts are slightly shorter in the new species, but long and C-shaped in E. nubilus (Fig. 1 D).	en	Liu, Fengjie, Agnarsson, Ingi, Liu, Jie, Zhu, Yang (2022): Description and phylogenetic analysis of two new Episinus (Araneae, Theridiidae) species from China.

This new species is similar to E. xiushanicus Zhu, 1998 in having a peach-shaped structure at the posterior part of the epigynal field but can be distinguished from them by the following characteristics: 1) abdomen without spinous process in ventral view, but the ventral protuberance is spinous in E. xiushanicus (Fig. 4 A); 2) spermathecae slightly S-shaped in the new species but W-shaped in E. xiushanicus (Fig. 4 D).	en	Liu, Fengjie, Agnarsson, Ingi, Liu, Jie, Zhu, Yang (2022): Description and phylogenetic analysis of two new Episinus (Araneae, Theridiidae) species from China.
