The genus Periclimenes Costa, 1844 is the most species-rich genus in the subfamily Pontoniinae. Recent studies have suggested that it might be a polyphyletic taxon and could be further subdivided. In this study, three protein-coding nuclear genes and one mitochondrial ribosomal gene were used to analyze the phylogenetic relationships among the genera of the Periclimenes complex, includes the genus Periclimenes and 15 related genera, viz. Ancylomenes, Brucecaris, Crinotonia, Cuapetes, Harpiliopsis, Harpilius, Laomenes, Leptomenaeus, Manipontonia, Palaemonella, Periclimenella, Philarius, Phycomenes, Unguicaris and Vir. Based on both independent and combined data analyses, the results support that the genus Periclimenes is a polyphyletic group. Furthermore, the studied Periclimenes species could be divided into several independent groups, and the taxonomic status of P. commensalis, P. brevicarpalis and P. digitalis may need to be reconsidered. Besides, the majority of the related genera of Periclimenes are suggested to be monophyletic. Our analyses also reveal that these genera approximately form two main clades, despite some deep relationships are still obscure.
属 Periclimenes Costa, 1844 是 Pontoniinae 亚科中物种最丰富的属。最近的研究表明，它可能是一个多系分类群，并可能进一步细分。在这项研究中，使用了三个蛋白质编码核基因和一个线粒体核糖体基因来分析 Periclimenes 复合体属的系统发育关系，包括属 Periclimenes 和 15 个相关属，即 Ancylomenes、Brucecaris、Crinotonia、Cuapetes、Harpiliopsis、Harpilius、Laomenes、Leptomenaeus、Manipontonia、Palaemonella、Periclimenella、Philarius、Phycomenes、Unguicaris 和 Vir。基于独立和联合数据分析的结果支持属 Periclimenes 是一个多系群。此外，研究的 Periclimenes 物种可以分为几个独立的群体，并且需要重新考虑 P. commensalis、P. brevicarpalis 和 P. digitalis 的分类地位。此外，大多数 Periclimenes 的相关属被认为是单系的。我们的分析还表明，这些属大致形成两个主要分支，尽管一些深层关系仍然不清楚。
