# The complete mitochondrial genome of Trirachys orientalis (Coleoptera: Cerambycidae)

## TL;DR

This paper reports the full mitochondrial genome of a long-horned beetle found in China, which could help with species identification and understanding its evolutionary relationships.

## Contribution

The study provides the first complete mitochondrial genome sequence of Trirachys orientalis and its phylogenetic analysis.

## Key findings

- The complete mitochondrial genome is 16,028 bp long with 29.60% GC content.
- It contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region.
- Phylogenetic analysis was conducted with 10 related species to clarify evolutionary relationships.

## Abstract

Trirachys orientalis (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.
