Based on the literature published between 1936 and 2019, a checklist is compiled for 16 nominal species in seven genera (Bomolochus [2 spp.], Naricolax [1 sp.], Nothobomolochus [5 spp.], Orbitacolax [3 spp.], Pumiliopes [1 sp.], Tegobomolochus [1 sp.], and Unicolax [3 spp.]) of the cyclopoid copepod family Bomolochidae from Japanese marine fishes. In a parasite-host list, information is given for each species on its Japanese name, current scientific name, previous scientific name(s) if present, host(s), site(s) of infection, collection site(s) in Japanese waters, and references. A host-parasite list is also given.
