Kazuya Nagasawa and Hirotaka Katahira

Abstract / Introduction / Summary:

A metamorphosed adult female of Lernaea cyprinacea Linnaeus, 1758 was found to parasitize a rock flagtail, Kuhlia rupestris (Lacepède, 1802), in the Miyara River on Ishigaki-jima Island, one of the Ryukyu Islands, southern Japan. This represents the first record of L. cyprinacea from Ishigaki-jima Island. Kuhlia rupestris is a new host record for L. cyprinacea.
