The complete mitochondrial genome of Varuna yui (Decapoda: Brachyura: Varunidae) and its phylogeny.

The complete mitochondrial genome plays an important role in the research on phylogenetic relationship. Here, we reported the first complete mitochondrial genome sequence of Varuna yui Hwang & Takeda, 1986 (Varunidae). The complete mtDNA (15,915 bp in length) consisted of 13 protein-coding genes, 22 tRNAs, two rRNA genes, and a control region. The gene arrangement was identical to those observed in the Varunidae species. The phylogenetic analysis suggested that V. yui had close relationship with other Varunidae species (Helicetient sinensis, Eriocher sinesis, etc.). The newly described genome may facilitate further comparative mitogenomic analysis within Varunidae species.
