# The mitochondrial genome of Huananpotamon koatenense (Rathbun, 1904) (Brachyura, Potamidae) and phylogenetic analysis

## TL;DR

This paper reports the first sequencing of the mitochondrial genome of a Chinese freshwater crab and uses it to study its evolutionary relationships with other crabs.

## Contribution

The first mitochondrial genome sequencing of Huananpotamon koatenense and its use in phylogenetic analysis within the genus.

## Key findings

- The mitochondrial genome of Huananpotamon koatenense is 15,528 bp long and includes 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes.
- Phylogenetic analysis shows H. koatenense clusters with H. lichuanense, a related species in the same genus.

## Abstract

Freshwater crabs play essential roles in the well-functioning of the inland aquatic ecosystems. However, due to the lack of sufficient molecular resources, the study of freshwater crabs has been greatly hindered. In this study, the mitochondrial genome of Huananpotamon koatenense, a freshwater crab endemic to China, was sequenced for the first time. This mitogenome sequence is 15,528 bp long, and contains 13 protein-coding genes, 2 rRNA genes and 22 tRNA genes. Phylogenetic analyses based on 25 mitogenomes showed that H. koatenense was clustered with the known congeneric species of H. lichuanense.
