We present a chromosome-level genome assembly from a single male Colydium elongatum (cylindrical bark beetle) belonging to Arthropoda, Insecta, Coleoptera, Zopheridae. The assembly spans 450.16 megabases, with 99.15% of sequence scaffolded into 10 chromosomal pseudomolecules, including X and Y sex chromosomes. The mitochondrial genome is assembled to 16.82 kilobases. Ensembl annotation identifies 13,883 protein-coding genes. The reference genome is generated under the Darwin Tree of Life project for eukaryotic species found in Britain and Ireland.

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.
