Research Abstract

Morphology and ribotype (genotype based on rDNA) of a harmful redtide forming dinoflagellate Cochlodinium polykrikoides was examined to reveal distribution of each ribotype. A new species C. fulvescens was described based on morphological comparison. A harmful species C. polykrikoides was divided into three ribotypes, East Asian, Philippines and American types in the phylogenetic tree. This indicates the redtides occurred in western Japanese coasts were formed by cells overwintering around the East China Sea.
