Mitogenome of Coprophanaeus ensifer and phylogenetic analysis of the Scarabaeidae family (Coleoptera)

Abstract

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.

Evolutionary history and diversity in the ball roller beetle Canthon cyanellus

“…Different analysis and phylogenetic approaches have brought advances in the systematics of Scarabaeinae dung beetles (Monaghan et al, 2007;Tarasov and Génier, 2015;Gunter et al, 2016;Tarasov and Dimitrov, 2016). Phylogenetic studies for taxonomic levels below subfamily are recent (Nolasco-Soto et al, 2017, 2020Hensen et al, 2018Hensen et al, , 2020Hensen et al, , 2021Maldaner et al, 2019;Pardo-Diaz et al, 2019;Mello et al, 2021;Moctezuma et al, 2021;Halffter et al, 2022). Those studies have explored different data sets (e.g., molecular, morphometric, behavioral, ecological).…”
