The superfamily Buccinoidea is distributed across the oceans of the world from the Arctic Ocean to the Antarctic and from intertidal to abyssal depths. It encompasses 3351 recent species in 337 genera. The latest taxonomic account recognized eight full families. For the first time, the monophyly of the superfamily and the relationships among the families are tested with molecular data supplemented by anatomical and radula data. Five genetic markers were used: fragments of mitochondrial COI, 16S rRNA, 12S rRNA and nuclear Histone 3 (H3) and 28S rRNA genes (for 225 species of 117 genera). Our analysis recovered Buccinoidea monophyletic in Bayesian analyses. The relationships between the formerly recognized families and subfamilies are drastically revised and a new classification of the superfamily is here proposed, now including 20 taxa of family rank and 23 subfamilies. Five new families (Chauvetiidae, Dolicholatiridae, Eosiphonidae, Prodotiidae and Retimohniidae) and one subfamily of Nassariidae (Tomliniinae) are described. Austrosiphonidae and Tudiclidae are resurrected from synonymy and employed in a new taxonomical extension. All but 40 recent genera are reclassified. Our results demonstrate that anatomy is rather uniform within the superfamily. With exceptions, the rather uniform radular morphology alone does not allow the allocation of genera to a particular family without additional molecular data.

Buccinoidea (Neogastropoda) 的分子系统发育和修订分类

Buccinoidea 超科分布于世界各大洋,从北冰洋到南极,从潮间带到深海。它包括 337 个属的 3351 个最近的物种。最新的分类账户承认了八个完整的家庭。首次用解剖学和齿状数据补充的分子数据检验了超科的单系性和科间的关系。使用了五个遗传标记:线粒体 COI 片段、16S rRNA、12S rRNA 和核组蛋白 3 (H3) 和 28S rRNA 基因(用于 117 属的 225 个物种)。我们的分析在贝叶斯分析中恢复了 Buccinoidea 单系。以前公认的家庭和亚科之间的关系被彻底修改,这里提出了一个新的超科分类,现在包括20个科级分类群和23个亚科。描述了五个新科(Chauvetiidae、Dolicholatiridae、Eosiphonidae、Prodotiidae 和 Retimohniidae)和一个 Nassariidae 亚科(Tomliniinae)。Austrosiphonidae 和 Tudiclidae 从同义词中复活并用于新的分类扩展。除了最近的 40 个属外,所有属都被重新分类。我们的研究结果表明,超家族内的解剖结构相当一致。除例外情况外,仅靠相当均匀的辐射状形态不允许在没有额外分子数据的情况下将属分配到特定科。Austrosiphonidae 和 Tudiclidae 从同义词中复活并用于新的分类扩展。除了最近的 40 个属外,所有属都被重新分类。我们的研究结果表明,超家族内的解剖结构相当一致。除例外情况外,仅靠相当均匀的辐射状形态不允许在没有额外分子数据的情况下将属分配到特定科。Austrosiphonidae 和 Tudiclidae 从同义词中复活并用于新的分类扩展。除了最近的 40 个属外,所有属都被重新分类。我们的研究结果表明,超家族内的解剖结构相当一致。除例外情况外,仅靠相当均匀的辐射状形态不允许在没有额外分子数据的情况下将属分配到特定科。
