Complete mitochondrial genome of the commensal scale worm, (Grube, 1855) (Polychaeta: Polynoidae), collected from benthic habitat of the eastern coast of Korea.

The complete mitogenome sequence of the commensal polynoid scale worm was determined for the first time in the present study. The total length of the newly sequenced mitogenome was 15,125 bp, including 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The phylogenetic position of was examined by maximum likelihood analysis using concatenated 13 protein-coding genes with 18 selected polychaete species. was nested within the suborder Aphroditiformia and closely related to among the selected species. The newly determined mitogenome sequence will be useful for further phylogenetic and evolutionary studies of this group.
