They belong to 3 genera, one of which, Majimun gen. n., is new. The parasites and their hosts are as follows: Ceratosomicola japonicasp. n. ex Hypselodoris festiva (A. Adams); Splanchnotrophus helianthussp. n. ex Thecacera pennigera (Montagu); Splanchnotrophus imagawaisp. n. ex Trapania miltabrancha Gosliner & Fahey; and Majimun shirakawaigen. et sp. n. ex Roboastra luteolineata (Baba) and Roboastra gracilis (Bergh). Ceratosomicola japonicasp. n. is the fifth species of Ceratosomicola and is characterized by the shape and armature of the prosome in females.
