Performance of tested annotation tools (MITOS2, MitoZ, MitoFlex, and GeSeq) for the reference mitochondrial genomes of C. sonorensis (A, B, C, and D) and C. arakawae (E, F, G, and H). Annotation results were represented by performance, where MITOS2 had the best performance in terms of gene annotation. PCGs, rRNA, and tRNA are indicated in green, brown, and orange, respectively. The control region (D-loop) and the intergenic spacers are noted in blue and red
