ABSTRACT The genus Acanthogonyaulax (Kofoid) H.W.Graham is a rarely observed tropical gonyaulacoid dinoflagellate, first documented at the end of the 19th century. It was initially described as a species of Ceratocorys F.Stein, then transferred to Gonyaulax Diesing, and finally to its own genus, Acanthogonyaulax. Discrepancies in the observations of its plate pattern were responsible for these changes. In this study, material from the Pacific and Indian Oceans provided evidence that Acanthogonyaulax, in spite of its similarities in plate pattern to Gonyaulax, has sufficiently important morphological differences to merit being its own genus.

关于刺棘果藻（Dinophyceae）

摘要 Acanthogonyaulax (Kofoid) HWGraham 属是一种很少观察到的热带角鞭毛藻，最早记录于 19 世纪末。它最初被描述为 Ceratocorys F.Stein 的一个物种，然后转移到 Gonyaulax Diesing，最后转移到它自己的属 Acanthogonyaulax。对其板块模式的观察差异是造成这些变化的原因。在这项研究中，来自太平洋和印度洋的材料提供的证据表明，尽管 Acanthogonyaulax 在板块模式上与 Gonyaulax 相似，但具有足够重要的形态差异，值得成为它自己的属。
