Figure 1. Mitochondrial genomes of four flat bugs sequenced in this study.

Circular maps were drawn with CGView⁶⁶. Arrows indicate the orientation of gene transcription. Abbreviations of gene names are: atp6 and atp8 for ATP synthase subunits 6 and 8, cox1–3 for cytochrome oxidase subunits 1–3, cob for cytochrome b, nad1–6 and nad4L for NADH dehydrogenase subunits 1–6 and 4L, lrRNA and srRNA for large and small rRNA subunits. tRNA genes are indicated with their one-letter corresponding amino acids. CR for control region. The GC content was plotted using a black sliding window, as the deviation from the average GC content of the entire sequence. GC-skew was plotted as the deviation from the average GC-skew of the entire sequence. The illustrations of four flat bugs were drawn by F.S.
