# The complete mitochondrial genome of Trichochrysea japana (Motschulsky, 1855) (Coleoptera: Chrysomeloidea) and its phylogenetic analyses

## TL;DR

This paper reports the first complete mitochondrial genome of the horticultural pest Trichochrysea japana and its evolutionary relationships with other species.

## Contribution

The study provides the first complete mitogenome of Trichochrysea japana and its phylogenetic placement.

## Key findings

- The complete mitogenome of T. japana is 15,681 bp in length and includes 13 protein-coding genes, 22 tRNAs, two rRNAs, and two control regions.
- Phylogenetic analysis shows T. japana is closely related to Basilepta melanopus, B. fulvipes, and Colasposoma dauricum.
- The mitogenome data offers insights into the genetic evolution of T. japana.

## Abstract

Trichochrysea japana (Motschulsky, 1855) (Coleoptera: Chrysomelidae) is a horticultural pest with a widespread distribution. However, the complete mitochondrial genome (mitogenome) of this species has not been available . In this study, we sequenced and analyzed the first complete mitogenome of T. japana. The mitogenome is 15,681 bp in length (GenBank accession number: OR387477) and includes 13 typicalPCGs, 22 tRNAs, two rRNAs, and two control regions. Furthermore, phylogenetic analysis indicated that T. japana is closely related to Basilepta melanopus, B. fulvipes, and Colasposoma dauricum. The T. japana mitogenome data provides valuable insights into the genetic evolution of this species .
