葡萄球菌是庞大的葡萄球菌科的第三大亚科。葡萄球菌科的单系性及其与Paederinae亚科的姐妹关系，直到最近三年才根据传统的形态学和分子系统发育学被广泛接受。近年来的分子系统发育学拒绝了葡萄球菌科的单一性，认为葡萄球菌科是葡萄球菌科中的一个分支。本文对近年来的分子工作进行了重新评价，旨在澄清葡萄球菌科与Paederinae的关系，解决葡萄球菌科内部的部落间关系。基于GenBank中已发表DNA数据的92个分类群（包括Oxyporinae（外群），Paederinae的代表，以及Staphylininae所有现存部落成员）的6个基因数据集（5707 bp），我们得到了Staphylininae所有深节点（部落间关系）强有力支持的良好解决系统发育，并使用贝叶斯和最大似然推断重申了Staphylininae是单系的假设，并且确实是Paederinae的姐妹群。此外，我们的研究是一个案例研究，表明外群选择和核苷酸数据的完整性都可以影响分子系统发育的结果。随着越来越多的葡萄球菌类化石被发现，我们的研究推断出葡萄球菌科强大的系统发育将为理解该类群的早期进化提供一个很好的框架。
Staphylininae is the third largest subfamily of the enormous family Staphylinidae. Monophyly of Staphylininae and its sister relationship to the subfamily Paederinae have been broadly accepted according to both conventional morphology- and molecular-based phylogenies until the last three years. Recent molecular phylogenies rejected monophyly of Staphylininae and regarded Paederinae as a clade within it. This paper re-evaluates the recent molecular work, aiming to clarify the relationship between Staphylininae and Paederinae and resolve intertribal relationships within Staphylininae. Based on a new six-gene data set (5707 bp) for 92 taxa including Oxyporinae (outgroup), representatives of Paederinae, and members of all extant tribes of Staphylininae from published DNA data in GenBank, we generated a well-resolved phylogeny of Staphylininae with all deep nodes (intertribal relationships) strongly supported, and reassert the hypothesis that Staphylininae is monophyletic and indeed the sister group to Paederinae using both Bayesian and maximum likelihood inference. Additionally, our study is a case-study to show that both outgroup selection and completeness of nucleotide data can influence the outcome of a molecular phylogeny. With an increasing number of staphylinid fossils being discovered, the robust phylogeny of Staphylininae inferred by our research will provide a good framework for understanding the early evolution of this group.
