## TL;DR

This paper presents the genome sequence of the soldier beetle Malthodes minimus, including its chromosomes and mitochondrial DNA, as part of a larger project to sequence species in Britain and Ireland.

## Contribution

The paper provides a high-quality reference genome for Malthodes minimus, including sex chromosomes and mitochondrial DNA.

## Key findings

- The genome assembly is 583.60 megabases long, with 97.75% scaffolded into 7 chromosomal pseudomolecules.
- The mitochondrial genome is 19.48 kilobases in length and has been fully assembled.
- The work is part of the Darwin Tree of Life project, which aims to sequence eukaryotic species in Britain and Ireland.

## Abstract

We present a genome assembly from an individual male
Malthodes minimus (soldier beetle; Arthropoda; Insecta; Coleoptera; Cantharidae). The genome sequence has a total length of 583.60 megabases. Most of the assembly (97.75%) is scaffolded into 7 chromosomal pseudomolecules, including the X and Y sex chromosomes. The mitochondrial genome has also been assembled, with a length of 19.48 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
