The first mitogenome report of Dimorphostylis asiatica Zimmer 1921 (Malacostraca: Cumacea)

Abstract

In 1921, Zimmer established the genus Dimorphostylis for Dimorphostylis asiatica from Japanese waters. This study determined the first complete mitogenome of hooded shrimp sequenced from Dimorphostylis asiatica (Cumacea: Diastylidae). D. asiatica is a type species of the genus Dimorphostylis, distributed in the West Pacific from southern Kuril to Vietnam, including Korean waters. The mitogenome is 14,888 base pairs (bp) long with a high A + T content of 70.9%. Phylogenetic analysis places Dimorphostylis within the Superorder Peracarida, providing new insights into the phylogeny and evolution of cumaceans and broader crustacean groups. This report provides a vital reference for further phylogenetic studies of cumaceans and enhances our molecular understanding of crustacean evolution.
