Abstract

We investigated the phylogenetic relationships among seven of the ten Halobatinae genera (Heteroptera: Gerridae) based on COI+II, 16S rRNA, and 28S rRNA genes. Our analyses recovered monophyly of Halobatinae, and suggested paraphyly of Metrocorini caused by the position of Ventidius and Esakia . Since our phylogenies did not infer monophyly of the subgenus Halobates (s.str.) within Halobatini, we synonymized Austrobates and Halobates ( Hilliella ) with Halobates . We confirmed that (1) the limnic lifestyle of Metrocorini was ancestral in Halobatinae, (2) the marine lifestyle evolved only once in the common ancestor of Asclepios + Halobates , (3) the limnic lifestyle of some members of Halobates was independently derived from marine ancestors, and that (4) the open ocean was colonized at least three times in Halobates . A catalogue of Halobatinae organized according to an updated classification is presented, including all known geographic distributions, bibliographical references, and additional notes to all species of the subfamily.

海滑动物的分子系统发育（Halobates Eschscholtz，1822），Halobatini和Metrocorini之间的关系，以及Halobatinae亚科的目录（半翅目：异翅目：Gerridae）

基于COI+II、16S rRNA和28S rRNA基因，我们研究了10个Halobatinae属（异翅目：Gerridae）中7个属的系统发育关系。我们的分析恢复了Halobatinae的单系性，并表明Metrocorini的副系性是由Ventidius和Esakia的位置引起的。由于我们的系统发育没有推断出Halobatini内Halobates亚属（s.str.）的单系性，我们将Austrobates和Halobates（Hilliella）与Halobates同义。我们证实：（1）Metrocorini的limnic生活方式起源于Halobatinae，（2）海洋生活方式在Asclepios+Halobates的共同祖先中只进化过一次，（3）Halobates一些成员的Limnice生活方式独立于海洋祖先，（4）公海在Halobates至少殖民过三次。根据更新的分类，提供了卤虫亚科的目录，包括所有已知的地理分布、参考文献和该亚科所有物种的附加注释。

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
