Table S5 Results from tests of linkage disequilibrium between pairs of loci across all species.

Table S6 Tests for selective neutrality and Hardy-Weinberg (H-W) equilibrium.

Table S7 Rates of introgression measured from IMa analyses.

Table S8 Effective population size parameters measured from IMa analyses (θ = 4Neμ).
