Complete mitochondrial genome and phylogenetic analysis of <i>Luciogobius parvulus</i> (Synder, 1909) (Teleostei, Gobiidae) from Korea

<i>Luciogobius parvulus</i> (Snyder, 1909) is distributed in restricted areas of Japan and South Korea. Here, we report the first complete mitochondrial genome of this species. The 16,488 bp mitogenome contains 13 protein-coding genes, 22 tRNAs, and two rRNAs, with no gene rearrangements detected. Four protein-coding genes (<i>COX2, COX3, ND4</i>, and <i>CytB</i>) exhibit incomplete stop codons. Maximum-likelihood analysis of Gobionellinae indicates that two <i>Luciogobius</i> species may require morphological reexamination. Only five of the 17 <i>Luciogobius</i> species currently have complete mitogenomes. These results provide essential genomic data for future phylogenetic and taxonomic studies.
