摘　　要：Despite worldwide distribution and rich diversity,the knowledge of mitochondrial genome(mtgenome)characteristics within the family Tenebrionidae(Coleoptera)is still very limited,and phylogenetics remain unresolved for the family.In this study,the mtgenomes for 12 species are newly sequenced and annotated.Three of the species represent the first report of complete mtgenomes from the subfamily Alleculinae.Comparative analysis of 36 tenebrionid mtgenomes finds that gene composition and order are the same as a theoretical ancestral insect mtgenome,and AT bias,length variation,and codon usage are consistent with other reported beetle mtgenomes.Some intergenic overlap and gap sequences may contain phylogenetically informative information,whereas neither the conserved nor repeat sequences in the control region do.The subfamilies Lagriinae,Pimeliinae,Stenochiinae,and Alleculinae are found to be monophyletic,and the subfamilies Diaperinae and Tenebrioninae polyphyletic in our study.Furthermore,Lagriinae is sister to the rest of the subfamilies.At the tribal level,the tribes Lagriini in the subfamily Lagrrinae;Strongyliini in Stenochiinae;Cteniopodini in Alleculinae;and Triboliini,Opatrini,and Amarygmini in Tenebrioninae are monophyletic;while Diaperini in Diaperinae,and Tenebrionini in Tenebrioninae are polyphyletic.
