Start and stop refer to the complete mitochondrial genome as referenced in supplementary file S1, Supplementary Material online; length, nucleotide length without stop codon; aa, amino acid length. All newly annotated atp8 are on the “+” strand; ORFs are listed in order of hit, as in supplementary file S19, Supplementary Material online.
