Holophryxus fusiformis Shiino, 1937, a species of dajid isopod that attaches to the carapace of sakura shrimp, Lucensosergia lucens (Hansen, 1922), is reported from the sea of Taiwan for the first time. This species was first described as infesting Prehensilosergia prehensilis (Bate, 1881) from Kanbara, Shizuoka Prefecture, Japan. The current finding represents the second occurrence of H. fusiformis and identifies a new host. Approximately 1% of the sakura shrimps in Yilan, Taiwan are infected by H. fusiformis. Holophryxus fusiformis has been found offshore from both Yilan, Taiwan and Nagasaki and in Suruga Bay, Japan; thus, the distribution of the parasite possibly follows the Kuroshio Current. When large quantities of parasites occur in the sea of Taiwan, the parasites are likely to flow into the Japanese waters along with the Kuroshio Current, subsequently influencing the production of the Japanese sakura shrimps. The establishment of a monitoring program for infection of the dajid in sakura shrimps between Taiwan and Japan is recommended. This study provides additional information on this species, including a new host, distribution, redescription, infection rate, and morphological variation.
