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 leng...
