Adult post-metamorphosis females of the lernaeid copepod Lernaea cyprinacea Linnaeus, 1758 were found to infect the freshwater goby, Rhinogobius sp. OR, in June 2018 in a pond of the Nakagawa Aquatic Park at Sarado, Nakagawa, Tochigi Prefecture, central Honshu, Japan. This represents a new host record for L. cyprinacea and its first record from the prefecture. Two (8.3%) of the 24 gobies examined harbored individually one and two females of L. cyprinacea. The pond is connected with the nearby Nakagawa River, and it is highly probable that L. cyprinacea invaded the pond as its free-living larvae and/or as adults infecting wild fishes from the river.
