ResumenThe turbellarian Urastoma cyprinae (Graff, 1882) Graff, 1903 was found inhabiting the mantle cavity between the lamellae of the demibranchs of mussels Mytilus galloprovincialis Lamarck cultured in Galicia (NW Spain). Heavily infested mussels were recognized by the presence of white spots in the gills. The affected area exhibited disarrangement of the gill filaments. The space between 2 lameliae was considerably reduced and the blood sinuses were wider in the unhealthy area than in the healthy area. The turbellarian also induced a heavy infiltration by blood cells and subsequent necrosis of the gill tissues. Routine parasitological studies showed that this parasite was first detected in the Galician region in early 1989. In 1993, U. cyprinae appeared to be present in the 3 main production rias in the Galician region, affecting both natural beds and rafted mussels. U. cyprinae could be considered a potential threat to mussel culture.
