Fig. 3

Graphics showing the nucleotide diversity of the mitochondrial genome of the four species. Nucleotide diversity of Cx. coronator, Cx. usquatus, Cx. camposi and Cx. usquatissimus was calculated using a sliding window analytical procedure (window of 200 base pairs with step size of 25 base pairs). Gene boundaries are indicated above the graph as follows: black vertical bars indicate tRNA genes, whereas the white boxes represent both protein-coding genes and ribosomal RNA genes. The featured rectangle shows the AT-rich control region
