The first published phylogenetic hypotheses involving members of the polychaete taxon Magelonidae Cunningham & Ramage, 1888, were reported by Mortimer et al. (2021), wherein results showed that for the two genera in the family, Magelona F. Müller, 1858, was paraphyletic relative to Octomagelona Aguirrezabalaga, Ceberio & Fiege, 2001. The only option to formally name at least some of the resultant phylogenetic hypotheses was to place Octomagelona into synonymy with Magelona, leaving the definition of Magelonidae redundant with that of a monophyletic Magelona. Meißner et al. (2023) subsequently described specimens as members of new species, Octomagelona borowskii Fiege, Knebelsberger & Meißner, 2023, and O. sp. cf. O. borowskii, with the view that Octomagelona should be maintained as distinct from Magelona. We present reasons why reestablishing the paraphyly of Magelona is scientifically unwarranted.
首次发表的涉及多毛纲分类单元马盖隆科（Cunningham & Ramage，1888）成员的系统发育假说由莫蒂默等人（2021年）报道，其中结果显示，对于该科的两个属，1858年的马盖隆属（F. Müller）相对于2001年的八马盖隆属（Aguirrezabalaga、Ceberio & Fiege）是并系的。正式命名至少一些由此产生的系统发育假说的唯一选择是将八马盖隆属归入马盖隆属的同物异名，从而使马盖隆科的定义与单系的马盖隆属的定义重复。迈斯纳等人（2023年）随后将标本描述为新物种八马盖隆·博罗夫斯基（Fiege、Knebelsberger & Meißner，2023）和八马盖隆属某种（近似八马盖隆·博罗夫斯基）的成员，认为八马盖隆属应与马盖隆属保持不同。我们阐述了恢复马盖隆属并系性在科学上毫无根据的原因。
