The complete mitochondrial genome of <i>Trirachys orientalis</i> (Coleoptera: Cerambycidae)

<i>Trirachys orientalis</i> (Hope, 1841) is a long-horned beetle widely distributed in China with economic importance and potential medicinal value. In this study, we sequenced and assembled its complete mitochondrial genome. The complete mitogenome is 16,028 bp in length with a GC content of 29.60%, including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region. We further made the phylogenetic tree on the complete mitochondrial genomes of other 10 closely related species to show their phylogenic relationship. This genomic resource provides a fundamental baseline for future species identification, phylogenetic resolution, and the exploration of its potential utility as a biological resource.
