## TL;DR

This paper presents the genome sequence of the Madeiran Speckled Wood butterfly, including detailed assemblies of its chromosomes and mitochondrial DNA.

## Contribution

The study provides a high-quality genome assembly for Pararge xiphia, including scaffolded haplotypes and a mitochondrial genome.

## Key findings

- The genome assembly includes two haplotypes totaling 528.41 and 523.51 megabases.
- Haplotype 1 is scaffolded into 28 chromosomal pseudomolecules, including the Z sex chromosome.
- The mitochondrial genome is assembled with a length of 15.27 kilobases.

## Abstract

We present a genome assembly from a male specimen of
Pararge xiphia (Madeiran Speckled Wood; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 528.41 megabases and 523.51 megabases. Most of haplotype 1 (99.02%) is scaffolded into 28 chromosomal pseudomolecules, including the Z sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.27 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
