Wei, Mian, Zhu, Yang, Liu, Jie, Zhang, He & Liu, Fengjie, 2025, New species and new combinations of the spider genus Baiyuerius Zhao, B. Li & S. Q. Li, 2023 (Araneae, Agelenidae, Coelotinae), Zootaxa 5636 (3), pp. 401-442 : 420

Baiyuerius cuii -species group

Diagnosis. Males of cuii- species group can be identified by the following combination of characters: 1) patella with two apophyses ( Figs 3C , 5C ); 2) process of dorsal margin of conductor without basal stalk and not serrated ( Figs 3B , 5B ); 3) distal end of the process laterally pointed ( Figs 3B , 5B ).

Distribution. China (Hubei Province, Sichuan Province and Yunnan Province).

Species included. Two species are included in this group: B. cuii sp. nov. and B. jiquanyui sp. nov.
