# The genome sequence of Ramsons hoverfly, Portevinia maculata (Fallén, 1817)

## TL;DR

This paper presents the genome sequence of the Ramsons hoverfly, including a detailed assembly and gene annotation.

## Contribution

The study provides the first genome assembly for Portevinia maculata, including chromosomal scaffolding and mitochondrial genome.

## Key findings

- The genome assembly spans 1,125.3 megabases and is scaffolded into 6 chromosomal pseudomolecules.
- The mitochondrial genome is 18.98 kilobases in length.
- Ensembl identified 24,849 protein coding genes in the assembly.

## Abstract

We present a genome assembly from an individual
Portevinia maculata (Ramsons hoverfly; Arthropoda; Insecta; Diptera; Syrphidae). The genome sequence is 1,125.3 megabases in span. Most of the assembly is scaffolded into 6 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 18.98 kilobases in length. Gene annotation of this assembly on Ensembl identified 24,849 protein coding genes.
