Table 2.

Percent mitochondrial cytochrome c oxidase I (COI) sequence divergence among species of North American Platynus (mean ± standard deviation). Uncorrected average pairwise distances are shown. Cells below diagonal give the mean between-species distances in %. Diagonal (shaded) cells give the mean within-species distances in %. Number of sequences in square brackets after species names.
