Genetic divergence among six lineages of Eucecidoses based on 2.7 Kb of mitochondrial sequences.

Above diagonal: pairwise phi (ST) values based on haplotype frequency only, which indicates low rates of gene flow among all lineages. All comparisons were statistically significant; P ≤0.05). Below diagonal, pairwise K2P distance (numbers in brackets indicate diversity within populations). See Fig 3 for detailed description of lineages.
