## TL;DR

This paper presents the genome sequence of the house spider, including detailed assembly of chromosomes and mitochondrial DNA.

## Contribution

The study provides a high-quality genome assembly of Eratigena atrica, including sex chromosomes and mitochondrial DNA.

## Key findings

- The genome assembly has a total length of 4,947.42 megabases.
- 98.73% of the assembly is scaffolded into 22 chromosomal pseudomolecules, including X1 and X2 sex chromosomes.
- The mitochondrial genome was assembled with a length of 14.25 kilobases.

## Abstract

We present a genome assembly from a male specimen of
Eratigena atrica (house spider; Arthropoda; Arachnida; Araneae; Agelenidae). The genome sequence has a total length of 4 947.42 megabases. Most of the assembly (98.73%) is scaffolded into 22 chromosomal pseudomolecules, including the X
1 and X
2 sex chromosomes. The mitochondrial genome was also assembled, with a length of 14.25 kilobases.
