The phylogeny of Lygaeoidea is examined using 45 complete mitogenomes of lygaeoid species and four outgroup species. The gene orientation and arrangement of the two mitogenomes are found to be consistent with typical Lygaeoidea mitochondrial features, comprising 37 genes, including 13 PCGs, 22 tRNAs, 2 rRNAs, and a control region. Nucleotide composition of the species was biased towards A and T, with the gene order identical to the putative ancestral arrangement of insects. Start codons, stop codons, RNAs, relative synonymous codon usage (RSCU), and nucleotide diversity (Pi) of Oxycarenidae exhibited characteristics similar to other families in Lygaeoidea.
