Despite the worldwide distribution and rich diversity of the superfamily Tenebrionoidea, the knowledge of the mitochondrial genomes (mtgenome) characteristics of the superfamily is still very limited and its phylogenetics and evolution remains unresolved. In present study, nineteen species of mtgenomes in Tenebrionoidea are newly sequenced and annotated, and a total of 90 mtgenomes are analyzed. There exist 37 genes for all 82 species of complete mtgenomes of 16 families investigated, and their characteristics are identical as reported mtgenomes of other Tenebrionoids. The Ka/Ks analysis suggests that all 13 PCGs have undergone a strong purifying selection. The phylogenetic analysis suggests the monophyly of Mordellidae, Ripiphoridae, Meloidae, Anthicidae, Oedemeridae, Pyrochroidae, Salpingidae, Scraptiidae, Lagriidae and Tenebrionidae, and the Mordellidae is sister to the Ripiphoridae. The “Tenebrionidae clade” and “Meloidae clade” are monophyletic, and both of them are sister groups. In the “Meloidae clade”, Anthicidae is sister to Meloidae. In the “Tenebrionidae clade”, the family Lagriidae and Tenebrionidae are sister groups. The divergence time analysis suggests that Tenebrionoidea originated in early Jurassic, Mordellidae, Meloidae and Oedemeridae in Cretaceous, Anthicidae, Lagriidae and Tenebrionidae in the early Cretaceous. The work lays a base for the study of mtgenome, phylogenetics and evolution of the superfamily Tenebrionoidea.
