Nine species of Hatschekiidae are (re-)described from Japanese actinopterygian fishes belonging to Ophidiiformes, Beryciformes and Scorpaeniformes. They are Hatschekia anomalis sp. nov., Hatschekia bifurcata Yamaguti & Yamasu, 1959, H. couardi Nunes-Ruivo, 1954, H. fusiformis Shiino, 1957, H. hoplobrotulae sp. nov., H. multibarbatae sp. nov., H. tenuis (Heller, 1865), Prohatschekia awatati (Yamaguti, 1939), and P. neobythitesi sp. nov. The first species is recovered from an unusual site of the host. In H. couardi and P. awatati the males are described for the first time and the possession of the naked first antennular segment is confirmed in both sexes of these species. The Hatschekiidae have paired seminal receptacles in the female and adopt the eudactylinid type of insemination mode, though exhibiting variation of the insemination procedure. It can be concluded that the insemination modes link up with the female genital system in the Siphonostomatoida.
