Specimens of the piscicolid leech Zeylanicobdella arugamensis de Silva, 1963 were collected from Mozambique tilapia Oreochromis mossambicus in a brackish-water inlet of Okinawa-jima Island, Okinawa Prefecture, southern Japan in May 2008. This finding represents the first record of Z. arugamensis in Japan and extends its geographic range from the Philippines north into southern Japan. The external morphology of the specimens is described. A literature review of the hosts, geographic distribution, and pathogenicity of the species reveals that it is not host-specific to teleosts and widely occurs in tropical and subtropical waters of the Indo-West Pacific region and that it is an important pathogenic parasite in finfish mariculture in the region.
