This study reports on the first trematode parasite observed in any species in the crustacean order Tanaidacea. Metacercariae occupying the body cavity of the host (Longiflagrum nasutus) were detected in 13 of 37 tanaidaceans collected from Manko Wetland, a Ramsar site on Okinawa Island, Japan. The morphology of the trematode and analyses of its 18S rRNA, 28S rRNA, and ITS1 nucleotide sequences suggest that it belongs in the family Microphallidae. Definitive hosts are not highly specific in microphallids, and are chiefly birds. Tanaidaceans have been reported in stomach contents from wading birds; L. nasutus was abundant at Manko Wetland, and is a likely prey for shorebirds there. This circumstantial evidence suggests an avian definitive host for the trematode in L. nasutus.
