The complete mitochondrial genome of <i>Hanabira yukibana</i> Lau, Stokvis, Imahara &amp; Reimer, 2019 (Cnidaria: Anthozoa: Octocorallia)

In this study, we sequenced the complete mitochondrial genome (mitogenome) of <i>Hanabira yukibana</i> (family Clavulariidae), collected in Okinawa, Japan. The complete mitochondrial genome of this specimen was 18,690 bp in length and contained 17 genes (14 protein-coding genes, two rRNA genes, and one tRNA gene). It exhibited gene order pattern A, which is the most common arrangement among octocorals. Molecular phylogenetic analysis indicated that <i>H. yukibana</i> is clustered with the genus <i>Clavularia</i>, including <i>Clavularia inflata</i> (the family Clavulariidae), consistent with the previous research using partial mitochondrial genes. This study corroborates the placement of the species <i>H. yukibana</i> in a monotypic genus. Our study provides an additional mitochondrial genomic resource that contributes to comparative studies of octocoral mitogenomes.
