Ju-shey Ho and Ching-Long Lin (2003) Comparative
studies of specimens of Caligus recovered from Scolopsis vosmeri
(Bloch), Lobotes surinamensis (Bloch), and Acanthopagrus schlegeli
Bleeker caught in the waters of Taiwan revealed that Caligus pagrosomi
Yamaguti, 1939 is a valid species, not synonymous with C. epinepheli
Yamaguti, 1936 as proposed by T. Byrnes in 1987. Furthermore, C.
epinepheli is restricted to the temperate waters of Asia and Oceania.
Those specimens reported as C. epinepheli from the Caribbean Sea by R.
F. Cressey in 1991 belong to a separate species, which is proposed to
be called Caligus cresseyi nom. nov. Moreover, a new subspecies,
Caligus pagrosomi schlegeli subsp. nov., is described based on the
specimens obtained from Taiwan.
Key words: Caligus epinepheli, Sea lice, Taiwan, Marine fish.
