Abstract / Introduction / Summary:
Ceratothoa verrucosa (Schioedte and Meinert, 1883) is a buccal-cavity parasite of sparid fishes in Japanese waters. Of seven individuals of red seabream Pagrus major (Temminck and Schlegel, 1843) examined from Kagoshima Bay off Ibusuki, Kagoshima Prefecture, southern Kyushu, in May 2016, one had an ovigerous female and a male of C. verrucosa in the buccal cavity. This represents the first and second records of C. verrucosa from Kagoshima Bay and the waters around Kyushu, respectively. This collection expands the distribution range of the species from Tomioka, Kumamoto Prefecture, central Kyushu, southward to Kagoshima Bay. The host and biogeographical records of the species are also reviewed.
