Diagnosis.

The females of C. ferrumequina differ from all other Campanicola species by the almost overlapping copulatory ducts except the short segment starting from the copulatory pores (Fig. 4F, H ). Males differ from all other Campanicola species by the long conductor tip and the part of the conductor above the cymbium with helical lines (Figs 5D-F , 6A-C ).

Description.

See Zhu (1998) and Yoshida (2000).

Distribution.

China (Hunan, Fujian, Sichuan, Hainan), Korea, Japan (Fig. 16 ).
