The mitochondrial genome of a dogielinotid amphipod, Haustorioides koreanus, was completely sequenced for the first time. The total mitogenome length of H. koreanus was 14,839bp with 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The phylogenetic tree confirmed that H. koreanus belongs to the families Hyalellidae in the same clade and to the suborder Senticaudata within Amphipoda. This is the first record of the complete mitochondrial genome sequence of the family Dogielinotidae.
