For the first time, the phylogenetic relationships between representatives of all 10 copepod orders have been investigated using 28S and 18S rRNA, Histone H3 protein and COI mtDNA. The monophyly of Copepoda (including Platycopioida Fosshagen, 1985) is demonstrated for the first time using molecular data. Maxillopoda is rejected, as it is a polyphyletic group. The monophyly of the major subgroups of Copepoda, including Progymnoplea Lang, 1948 (=Platycopioida); Neocopepoda Huys and Boxshall, 1991; Gymnoplea Giesbrecht, 1892 (=Calanoida Sars, 1903); and Podoplea Giesbrecht, 1892, are supported in this study. Seven copepod orders are monophyletic, including Platycopioida, Calanoida, Misophrioida Gurney, 1933; Monstrilloida Sars, 1901; Siphonostomatoida Burmeister, 1834; Gelyelloida Huys, 1988; and Mormonilloida Boxshall, 1979. Misophrioida (=Propodoplea Lang, 1948) is the most basal Podoplean order. The order Cyclopoida Burmeister, 1835, is paraphyletic and now encompasses Poecilostomatoida Thorell, 1859, as a sister to the family Schminkepinellidae Martinez Arbizu, 2006. Within Harpacticoida Sars, 1903, both sections, Polyarthra Lang, 1948, and Oligoarthra Lang, 1948, are monophyletic, but not sister groups. The order Canuelloida is proposed while maintaining the order Harpacticoida s. str. (Oligoarthra). Cyclopoida, Harpacticoida and Cyclopinidae are redefined, while Canuelloida ordo. nov., Smirnovipinidae fam. nov. and Cyclopicinidae fam. nov are proposed as new taxa.
首次利用 28S 和 18S rRNA、组蛋白 H3 蛋白和 COI mtDNA 研究了所有 10 个桡足类目代表的系统发育关系。使用分子数据首次证明了桡足类（包括 Platycopioida Fosshagen，1985）的单系性。Maxillopoda 被拒绝，因为它是一个多系群。本研究支持桡足类的主要亚群，包括 Pro gymnoplea Lang，1948（=Platycopioida）；Neocopepoda Huys 和 Boxshall，1991；Gymnoplea Giesbrecht，1892（=Calanoida Sars，1903）；和 Podoplea Giesbrecht，1892 的单系性。本研究支持 7 个桡足类目是单系的，包括 Platycopioida、Calanoida、Misophrioida Gurney，1933；Monstrilloida Sars，1901；Siphonostomatoida Burmeister，1834；Gelyelloida Huys，1988；和 Mormonilloida Boxshall，1979。Misophrioida（=Propodoplea Lang，1948）是最基础的 Podoplean 目。Cyclopoida Burmeister，1835 是并系的，现在包含 Poecilostomatoida Thorell，1859，作为 Schminkepinellidae Martinez Arbizu，2006 的姐妹群。在 Harpacticoida Sars，1903 中，Polyarthra Lang，1948 和 Oligoarthra Lang，1948 两个部分都是单系的，但不是姐妹群。在保持 Harpacticoida s.str.（Oligoarthra）的情况下，提出了 Canuelloida 目。重新定义了 Cyclopoida、Harpacticoida 和 Cyclopinidae，同时提出了 Canuelloida ordo.nov.、Smirnovipinidae fam.nov.和 Cyclopicinidae fam.nov.作为新分类单元。
