In 2006, a species of dinofiagellate was collected from Xiangxi River, Hubei province. By observation of optical microscope and scanning electron microscopy, it was identified as Perdinium polonicum, a new record in China. Literature indicated that it is a toxic blooming-species in lakes or ponds;and causes mortality of fish. This species is the only record of freshwater toxic dinoflagellate currently; its impaction on environment and ecology need to be further concerned.
