Pagina tunica Cressey, 1964 (Copepoda, Siphonostomatoida, Pandaridae) was found parasitic on three species of sharks from Taiwan. The sharks are: bigeye thresher, Alopias superciliosus (Lowe); oceanic whitetip shark, Carcharhinus longimanus (Poey); and blue shark, Prionace glauca (Linnaeus). All sharks were caught off Tai-dong located on the southeast coast of Taiwan. This paper gives a complete redescription of P. tunica based on the newly collected specimens from Taiwan.
