# The complete mitochondrial genome of a rarely reported porcelain crab, Pisidia striata (Anomura, Galatheoidea, Porcellanidae), from the Chinese waters

## TL;DR

This paper reports the full mitochondrial genome of a rare porcelain crab found in Chinese waters, providing insights into its evolutionary relationships.

## Contribution

The complete mitochondrial genome of Pisidia striata is newly sequenced and analyzed for phylogenetic relationships.

## Key findings

- The mitochondrial genome is 15,357 bp long with 13 protein-coding genes, 22 tRNAs, and 2 rRNAs.
- Pisidia striata is closely related to P. serratifrons within the Pisidia clade with strong phylogenetic support.
- The genome provides a valuable resource for evolutionary studies of the Porcellanidae family.

## Abstract

The species Pisidia striata is predominantly distributed along the southeastern coast of China and belongs to the shallow-water crab family Porcellanidae. The complete mitochondrial genome of P. striata, which spans 15,357 bp and contains 13 protein-coding genes, 22 tRNAs and 2 rRNAs, is presented in this study. The nucleotide composition reveals A (37.81%), T (35.48%), G (9.75%), and C (16.96%). Phylogenetic analysis demonstrates a close relationship between P. striata and P. serratifrons within the Pisidia clade with robust bootstrap support values. This mitochondrial genome will be a significant supplement for the genus Pisidia and whole mitogenome phylogenetic analysis provided insights into further evolutionary research of Porcellanidae.
