̶fusiformis Shiino，1937，是一种附着在樱虾壳上的等足类，为首次在台湾海域发现。本种首次被描述为寄生于日本静冈县关原市的Prehensilosergia grasisilis(Bate，1881)。目前的发现代表了羊毛虫的第二次出现，并确定了一种新的宿主。在台湾宜兰，大约1%的樱花虾感染了梭形螺旋体。在台湾宜兰、长崎近海和日本Suruga湾都发现了该寄生虫，因此，该寄生虫的分布可能遵循黑潮潮流。当台湾海域出现大量寄生虫时，这些寄生虫很可能会随黑潮涌入日本海域，进而影响日本樱虾的生产。建议建立台湾与日本间樱花虾感染大黄鱼的监测计划。这项研究提供了关于该种的更多信息，包括新寄主、分布、重新描述、感染率和形态变异。
̶ 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.
