Diagnosis. Yuelushannus jinyuanensis sp. n. resembles Y. wenfengensis sp. n. in having the similar spermathecae and copulatory ducts (Figs 303A–C, Figs 305A–C), but can be distinguished by the dorsal plate longer than wide posteriorly in Y. jinyuanensis sp. n. (Figs 303A–C), vs. wider than long in Y. wenfengensis sp. n. (Figs 305A–C); spermathecae not touches the posterior margin of the epigynal plate in Y. jinyuanensis sp. n. (Figs 303A–C), vs. touches the posterior margin of the epigynal plate in Y. wenfengensis sp. n. (Figs 305A–C).

Dorsal plate (DP) longer than wide posteriorly; copulatory ducts (CD) form spiral loop before joining the spermathecae; spermathecae (S) round, present posterio-lateraly on the dorsal plate and not touches the posterior margin of the epigynal plate, pointing away from each other; fertilization ducts (FD) extending mesally.
