# The genome sequence of the Mediterranean Skipper, Gegenes nostrodamus (Fabricius, 1793) (Lepidoptera: Hesperiidae)

## TL;DR

This paper reports the genome sequence of the Mediterranean Skipper butterfly, including two haplotypes and a mitochondrial genome.

## Contribution

The novel contribution is the first genome assembly for Gegenes nostrodamus, including chromosomal pseudomolecules and sex chromosomes.

## Key findings

- The genome assembly includes two haplotypes totaling 499.73 and 419.20 megabases.
- Haplotype 1 is scaffolded into 16 chromosomal pseudomolecules, including W and Z sex chromosomes.
- The mitochondrial genome is 18.43 kilobases long.

## Abstract

We present a genome assembly from a female specimen of
Gegenes nostrodamus (Mediterranean Skipper; Arthropoda; Insecta; Lepidoptera; Hesperiidae). The assembly contains two haplotypes with total lengths of 499.73 megabases and 419.20 megabases. Most of haplotype 1 (99.52%) is scaffolded into 16 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 18.43 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
