The Gempylidae (snake mackerels) family, belonging to the order Perciformes, consists of about 24 species described in 16 genera primarily distributed in tropical, subtropical, and temperate seas worldwide. Despite substantial research on this family utilizing morphological and molecular approaches, taxonomy categorization in this group has remained puzzling for decades prompting the need for further investigation into the underlying evolutionary history among the gempylids using molecular tools. In this study, we assembled eight complete novel mitochondrial genomes for five Gempylidae species (<i>Neoepinnula minetomai</i>, <i>Neoepinnula orientalis</i>, <i>Rexea antefurcata</i>, <i>Rexea prometheoides</i>, and <i>Thyrsites atun</i>) using Ion Torrent sequencing to supplement publicly available mitogenome data for gempylids. Using Bayesian inference and maximum-likelihood tree search methods, we investigated the evolutionary relationships of 17 Gempylidae species using mitogenome data. In addition, we estimated divergence times for extant gempylids. We identified two major clades that formed approximately 48.05 (35.89-52.04) million years ago: Gempylidae 1 (<i>Thyrsites atun</i>, <i>Promethichthys prometheus</i>, <i>Nealotus tripes</i>, <i>Diplospinus multistriatus</i>, <i>Paradiplospinus antarcticus</i>, <i>Rexea antefurcata</i>, <i>Rexea nakamurai</i>, <i>Rexea prometheoides</i>, <i>Rexea solandri</i>, <i>Thyrsitoides marleyi</i>, <i>Gempylus serpens</i>, and <i>Nesiarchus nasutus</i>) and Gempylidae 2 (<i>Lepidocybium flavobrunneum</i>, <i>Ruvettus pretiosus</i>, <i>Neoepinnula minetomai</i>, <i>Neoepinnula orientalis</i>, and <i>Epinnula magistralis</i>). The present study demonstrated the superior performance of complete mitogenome data compared with individual genes in phylogenetic reconstruction. By including <i>T. atun</i> individuals from different regions, we demonstrated the potential for the application of mitogenomes in species phylogeography.
