Complete mitochondrial genome sequence of the genus Austinograea (Malacostraca: Brachyura: Bythograeidae) and its phylogenetic analysis

Austinograea species are restricted to hydrothermal vents and are typically considered to be omnivorous predators in vent communities. Here we present the complete mitochondrial genome of Austinograea sp. which was collected from Carlsberg Ridge, the mid-ocean ridge in the northwestern Indian Ocean. The genome is 15,584 bp in length with a 68.11% AT content. It contains 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and 22 transfer RNA genes. Phylogenetic analysis shows that the present species is closest to Austinograea rodriguezensis. This study contributes to further phylogenetic analysis within Eubrachyura.
