Taxonomy
This genus currently contains five described species. This genus traditionally contained the four species however specimens collected from the Kara Sea show that they form a monophyletic group. This group was described in 2026 as Cylichnoides karaensis.3
Species belonging to this genus are listed below:12
- Cylichnoides densistriatus (Leche, 1878)
- Cylichnoides karaensis E. Chaban, D. Schepetov, M. Stanovova, N. Zhuravliova, A. Mirolyubov, I. Ekimova, 2026
- Cylichnoides occultus (Mighels & C. B. Adams, 1842)
- Cylichnoides scalptus (Reeve, 1855)
