The true bug infraorder Nepomorpha contains 11 families with classifications mostly using morphological features and not based on phylogenetic analyses. Presented here is the first molecular-based phylogeny for a family of Nepomorpha including more than half of the constituent taxa. Two nuclear (18S rRNA and 28S rRNA) and two mitochondrial (COI and COII) genes were used to reconstruct phylogenetic relationships with both Bayesian inference and maximum likelihood analyses. Ingroup taxa included all six subfamilies, 41 of the 43 genera, and 221 species and subspecies. Results of the analyses were mostly congruent and revealed Naucoridae to be monophyletic, but two of the subfamilies (Cheirochelinae and Naucorinae) and three genera (Heleocoris, Laccocoris and Naucoris) as polyphyletic. Two clades formerly in Naucorinae were recovered as distinct subfamily-level clades: Macrocorinae subfam. nov. contains the African Macrocoris and Neomacrocoris, and Ilyocorinae stat. nov. contains the Palaearctic Ilyocoris and Neotropical Placomerus. Laccocorinae is unchanged in its constituent membership, but its organization now includes four tribe-level groups. Limnocorinae and the recently revised Cryphocricinae and Ambrysinae are unchanged. An annotated list of all subfamily-, tribe- and genus-group taxa is presented, including new taxa descriptions, synonymies and new combinations.

飞碟虫的系统发育和修订分类（半翅目：Nepomorpha：Naucoridae）

真正的臭虫亚目 Nepomorpha 包含 11 个科，其分类主要使用形态特征，而不是基于系统发育分析。这里介绍的是第一个基于分子的 Nepomorpha 家族的系统发育，包括超过一半的组成分类群。两个核（18S rRNA 和 28S rRNA）和两个线粒体（COI 和 COII）基因被用来重建贝叶斯推断和最大似然分析的系统发育关系。内群分类群包​​括所有六个亚科、43 个属中的 41 个、221 个物种和亚种。分析结果大体一致，揭示了鹦鹉螺科是单系的，但其中两个亚科（角螯足亚科和鹦鹉螺亚科）和三个属（Heleocoris、Laccocoris 和 Naucoris）是多系的。以前在 Naucorinae 中的两个进化枝被恢复为不同的亚科水平进化枝：Macrocorinae subfam。十一月 包含非洲 Macrocoris 和 Neomacrocoris 以及 Ilyocorinae 统计数据。十一月 包含Palaearctic Ilyocoris 和Neotropical Placomerus。Laccocorinae 的组成成员没有变化，但它的组织现在包括四个部落级别的群体。Limnocorinae 和最近修订的 Cryphocricinae 和 Ambrysinae 没有改变。提供了所有亚科、部落和属组分类群的注释列表，包括新分类群描述、同义词和新组合。但它的组织现在包括四个部落级别的团体。Limnocorinae 和最近修订的 Cryphocricinae 和 Ambrysinae 没有改变。提供了所有亚科、部落和属组分类群的注释列表，包括新分类群描述、同义词和新组合。但它的组织现在包括四个部落级别的团体。Limnocorinae 和最近修订的 Cryphocricinae 和 Ambrysinae 没有改变。提供了所有亚科、部落和属组分类群的注释列表，包括新分类群描述、同义词和新组合。
