# The complete mitochondrial genome of Ischiodon scutellaris (Diptera: Syrphidae: Syrphinae)

## TL;DR

This paper presents the first complete mitochondrial genome of the syrphid fly Ischiodon scutellaris and explores its evolutionary relationships with other species.

## Contribution

The study provides the first complete mitochondrial genome sequence for Ischiodon scutellaris and contributes to syrphid mitochondrial genomics.

## Key findings

- The mitochondrial genome is 15,815 bp long with an A + T content of 80.7%.
- Phylogenetic analysis shows I. scutellaris is closely related to Scaeva affinis and Eupeodes species.
- Three protein-coding genes use an incomplete T stop codon.

## Abstract

This study reports the first complete mitochondrial genome of Ischiodon scutellaris. The mitochondrial genome is 15,815 bp in length, with an A + T content of 80.7%. The genome contains 13 protein-coding genes (PCGs), 22 tRNAs, 2 rRNAs, and a control region. All PCGs initiate with ATN (G/C/T), except COX1and ND1(TTG). Three PCGs (COX1, ATP6, ND5) terminate with an incomplete T stop codon. Phylogenetic analysis based on 13 PCG sequences using maximum likelihood revealed that I. scutellaris forms a sister clade with Scaeva affinis and clusters closely with multiple Eupeodes species. This study advances understanding of syrphid mitochondrial genomics and evolutionary relationships.
