# The genome sequence of the Cockspur worm, Bimastos rubidus (Savigny, 1826) (Crassiclitellata: Lumbricidae)

## TL;DR

This paper presents the genome sequence of the Cockspur worm, a type of earthworm, as part of a larger project to sequence species native to Britain and Ireland.

## Contribution

The novel contribution is the first reference genome assembly for Bimastos rubidus, including a detailed mitochondrial genome.

## Key findings

- The genome assembly is 812.74 megabases long with 95.63% scaffolded into 17 chromosomal pseudomolecules.
- The mitochondrial genome is 16.57 kilobases long and fully assembled.
- The work is part of the Darwin Tree of Life project focusing on species from Britain and Ireland.

## Abstract

We present a genome assembly from an individual
Bimastos rubidus (Cockspur worm; Annelida; Clitellata; Crassiclitellata; Lumbricidae). The genome sequence has a total length of 812.74 megabases. Most of the assembly (95.63%) is scaffolded into 17 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 16.57 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.
