The first complete mitochondrial genome of Dufouriellini (Hemiptera: Anthocoridae) and implications for its phylogenetic position

The mitochondrial genome (mitogenome) is extensively used to better understand the phylogenetic relationships within the family level, but there are still limited representations at the tribe level of Anthocoridae. Here we describe the first complete mitogenome of Dufouriellini. The mitogenome of Cardiastethus sp. is 15,209 bp in size, containing 13 typical protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a control region. All genes are arranged in the same gene order as the most other known cimicomorphan mitogenomes. The phylogenetic relationships based on mitogenomes using Bayesian inference and maximum likelihood methods show that Dufouriellini is sister to Anthocorini, and then both of them together form sister group with Oriini. The monophyly of each superfamily of Cimicomorpha is generally well supported. Reduvioidea is basal within Cimicomorpha. The topology of the remaining superfamily is as follows: (Miroidea + (Cimicoidea + (Velocipedoidea + Nabioidea))). This study will help to enhance our understanding of mitochondrial genomic evolution and phylogenetic relationships in the tribe level of Anthocoridae and also superfamily level of Cimicomorpha.
