## TL;DR

This paper provides the genome sequence of the Southern Grizzled Skipper butterfly, including two haplotypes and a mitochondrial genome.

## Contribution

The study presents a high-quality genome assembly for Pyrgus malvoides, including haplotype-specific scaffolding and a mitochondrial genome.

## Key findings

- The genome assembly includes two haplotypes totaling 746.71 and 747.11 megabases.
- Haplotype 1 is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome.
- The mitochondrial genome is assembled with a length of 15.41 kilobases.

## Abstract

We present a genome assembly from a male specimen of
Pyrgus malvoides (Southern Grizzled Skipper; Arthropoda; Insecta; Lepidoptera; Hesperiidae). The assembly contains two haplotypes with total lengths of 746.71 megabases and 747.11 megabases. Most of haplotype 1 (99.8%) is scaffolded into 31 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 15.41 kilobases.
