Abstract

Rove beetles (Staphylinidae) and allied families constitute a huge radiation of Coleoptera, but basal relationships in this group remain controversial. In this study, we newly sequenced eight mitogenomes of representatives of Staphylinidae by using next-generation sequencing method. Together with 99 existing mitogenomes of Staphyliniformia, (sub)family relationships were investigated with ML and Bayesian searches under various substitution models and data recoding schemes. The results consistently supported Scydmaenidae and Silphidae to be subordinate groups of Staphylinidae. Within the monophyletic Staphylinidae (including Scydmaenidae and Silphidae), the hypothesis of four major subfamily groups cannot be confirmed. Bayesian inferences under the site-heterogeneous mixture model generally supported the basal position of major clades corresponding to the Omaliine group. At the subfamily level, the monophyly of Pselaphinae, Oxytelinae, Scaphidiinae, Steninae and Staphylininae was supported. However, the subfamilies Omaliinae, Tachyporinae, Aleocharinae and Paederinae were each non-monophyletic.

从线粒体基因组序列推断的甲虫(鞘翅目、葡萄科)的高级系统发育关系

摘要

罗夫甲虫 (Staphylinidae) 及其相关科构成了鞘翅目的巨大辐射,但该组的基础关系仍存在争议。在这项研究中,我们使用下一代测序方法对葡萄球菌科代表的八个有丝分裂基因组进行了新测序。与 99 个现有的葡萄球菌有丝分裂基因组一起,在各种替代模型和数据重新编码方案下,用 ML 和贝叶斯搜索研究了(亚)家族关系。结果一致支持 Scydmaenidae 和 Silphidae 是 Staphylinidae 的下属组。在单系 Staphylinidae(包括 Scydmaenidae 和 Silphidae)中,四个主要亚科群的假设无法得到证实。位点非均质混合模型下的贝叶斯推论通常支持对应于 Omaliine 组的主要进化枝的基础位置。在亚科水平上,支持 Pselaphinae、Oxytelinae、Scophidiinae、Steninae 和 Staphylininae 的单系。然而,Omaliinae、Tachyporinae、Aleocharinae 和 Paederinae 亚科都是非单系的。
