Several studies about the phylogenetic relationships of the Scarabaeinae subfamily (Coleoptera: Scarabaeidae) have been performed, but some phylogenetic uncertainties persist including the relationship and monophyly of different tribes and some genera. The aim of this study was to characterize the mitogenome of Coprophanaeus ensifer in order to establish its position within the Scarabaeidae family and to contribute to the resolution of some phylogenetic uncertainties. The mitogenome was sequenced on the Illumina HiSeq 4000, assembled using the Mitobim software and annotated in MITOS WebServer. The phylogenetic trees were reconstructed by Bayesian inference. The C. ensifer mitogenome is a molecule of 14,964 bp that contains the number and organization of the genes similar to those of most Coleoptera species. Phylogenetic reconstruction suggests monophyly of the tribe Phanaeini and supports the hypothesis that Coprini is a sister group of Phanaeini. The results also revealed the position of the tribe Oniticellini which is grouped with Onthophagini and Onitini. The geographic distribution of these species that form the most ancestral clade suggests with Scarabaeinae originated in Africa.

Coprophanaeus ensifer 的丝裂基因组和金龟科（鞘翅目）的系统发育分析。

已经进行了一些关于金龟子亚科（鞘翅目：金龟子科）的系统发育关系的研究，但一些系统发育的不确定性仍然存在，包括不同部落和一些属的关系和单系。本研究的目的是表征 Coprophanaeus ensifer 的有丝分裂基因组，以确定其在金龟科家族中的位置，并有助于解决一些系统发育的不确定性。有丝分裂基因组在 Illumina HiSeq 4000 上测序，使用 Mitobim 软件组装并在 MITOS WebServer 中注释。系统发育树通过贝叶斯推理重建。C. ensifer 丝裂基因组是一个 14,964 bp 的分子，其中包含与大多数鞘翅目物种相似的基因数量和组织。系统发育重建表明 Phanaeini 部落的单系性，并支持 Coprini 是 Phanaeini 姐妹群的假设。结果还揭示了与 Onthophagini 和 Onitini 归为一组的 Oniticellini 部落的位置。这些形成最古老进化枝的物种的地理分布表明金龟子科起源于非洲。
