# The genome sequence of the cylindrical bark beetle, Colydium elongatum (Fabricius, 1787) (Coleoptera: Zopheridae)

## TL;DR

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

## Contribution

The paper provides the first reference genome for Colydium elongatum, including sex chromosomes and mitochondrial DNA.

## Key findings

- The genome assembly is 450.16 megabases long, with 99.15% scaffolded into 10 chromosomal pseudomolecules.
- The mitochondrial genome is 16.82 kilobases long and was fully assembled.
- Gene annotation identified 13,883 protein-coding genes.

## Abstract

We present a genome assembly from an individual male
Colydium elongatum (cylindrical bark beetle; Arthropoda; Insecta; Coleoptera; Zopheridae). The genome sequence has a total length of 450.16 megabases. Most of the assembly (99.15%) is scaffolded into 10 chromosomal pseudomolecules, including the X and Y sex chromosomes. The mitochondrial genome has also been assembled, with a length of 16.82 kilobases. Gene annotation of this assembly on Ensembl identified 13 883 protein-coding genes. 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.
