# Characterization of the complete mitochondrial genome of Hynobius bambusicolus Wang, Othman, Qiu and Borzée, 2023 (Amphibia, Caudata, Hynobiidae) and its phylogenetic implications

## TL;DR

This paper reports the full mitochondrial genome of a newly discovered salamander species and its evolutionary placement.

## Contribution

The study provides the first complete mitochondrial genome sequence for Hynobius bambusicolus and its phylogenetic analysis.

## Key findings

- The mitogenome of H. bambusicolus is 16,406 bp long with typical mitochondrial gene content.
- Phylogenetic analysis shows H. bambusicolus is the basal branch in the Southern Chinese Hynobius clade.

## Abstract

Hynobius bambusicolus (Caudata, Hynobiidae) is a recently described species, identified in 2022, and is thus not widely known. In this study, we sequenced and annotated the complete mitogenome of H. bambusicolus. The resulting mitochondrial genome is 16,406 bp in length and comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNA), 22 transfer RNA genes, and a non-coding region. The base composition of the mitogenome is 33.3% A, 32.1% T, 20.8% C, and 13.8% G. The phylogenetic trees indicated that H. bambusicolus is the basal branch within the Southern Chinese Hynobius clade.
