Abstract

An ovigerous female of Lernaea cyprinacea Linnaeus, 1758 (Lernaeidae) was collected in January 2013 from Kuro-yoshinobori, Rhinogobius brunneus (Temminck and Schlegel, 1845), in the upper reaches of the Genka River, a subtropical mountain stream on Okinawa-jima Island, one of the Ryukyu Islands, Okinawa Prefecture, southern Japan. This represents the third record of L. cyprinacea from the prefecture. The species is highly likely to spawn even in winter. No infection of L. cyprinacea was found on the fishes from the middle reaches of the river.
