The dinoflagellate genus Chytriodinium, an ectoparasite of copepod eggs, is reported for the first time in the North and South Atlantic Oceans. We provide the first large subunit rDNA (LSU rDNA) and Internal Transcribed Spacer 1 (ITS1) sequences, which were identical in both hemispheres for the Atlantic Chytriodinium sp. The first complete small subunit ribosomal DNA (SSU rDNA) of the Atlantic Chytriodinium sp. suggests that the specimens belong to an undescribed species. This is the first evidence of the split of the Gymnodinium clade: one for the parasitic forms of Chytriodiniaceae (Chytriodinium, Dissodinium), and other clade for the free-living species.
首次在北大西洋和南大西洋报道了作为桡足类卵外寄生虫的裸甲藻属（Chytriodinium）。我们提供了首个大亚基核糖体DNA（LSU rDNA）和内转录间隔区1（ITS1）序列，大西洋裸甲藻（Chytriodinium sp.）在两个半球的这些序列是相同的。大西洋裸甲藻（Chytriodinium sp.）的首个完整小亚基核糖体DNA（SSU rDNA）表明这些标本属于一个未描述的物种。这是裸甲藻分支分裂的首个证据：一个分支是寄生性的夜蛾藻科（Chytriodiniaceae，包括裸甲藻属、离甲藻属），另一个分支是自由生活的物种。
