# The genome sequence of the Northern Summer Mayfly, Siphlonurus alternatus (Say, 1824)

## TL;DR

This paper presents the genome sequence of the Northern Summer Mayfly, including a detailed assembly of its chromosomes and mitochondrial DNA.

## Contribution

The paper provides the first genome assembly for Siphlonurus alternatus, including scaffolded chromosomal pseudomolecules and the mitochondrial genome.

## Key findings

- The genome assembly spans 455.8 megabases and is scaffolded into 11 chromosomal pseudomolecules.
- The mitochondrial genome is 19.36 kilobases in length and has been fully assembled.

## Abstract

We present a genome assembly from an individual male
Siphlonurus alternatus (the Northern Summer Mayfly; Arthropoda; Insecta; Ephemeroptera; Siphlonuridae). The genome sequence is 455.8 megabases in span. Most of the assembly is scaffolded into 11 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 19.36 kilobases in length.
