Abstract

The complete mitochondrial genome of Brachyrhynchus triangulus Bergroth, 1889 was sequenced and annotated in the present study. It was a typical circular DNA molecule of 15,170 bp, with 37 genes and a control region. The percentages of A, C, G, and T nucleotides in the genome of B. triangulus were 41.1%, 17.4%, 11.9%, and 29.4%, respectively. Thirteen protein-coding genes (PCGs) start with a ATN codon or a TTG codon and terminate with a TAA codon or a TAG codon or a single T residue. With the exception of tRNA^Ser(AGN) , each of the 22 tRNA genes had a clover-leaf structure and ranged in length from 62 to 69 bp. The length of lrRNA and srRNA was 1241 bp and 828 bp, respectively. The control region had a length of 708 bp and an A + T content of 74.6%. The sister relationship between B. triangulus and Brachyrhynchus hsiaoi is supported by the phylogenetic tree. Additionally, it proved the sister relationship between Mezirinae and Aneurinae, supporting the classical taxonomy of the Aradidae.
