Maximum likelihood phylogeny using four-fold degenerate sites and a transversional mutation model with a proportion of invariable sites and a gamma distribution of rate heterogeneity (TVM + I + Γ; [79]). The colors for the branch tip labels correspond to the six different taxa in this study. The numbers at the major branch nodes indicate bootstrap support for each bifurcation in the tree (out of 100). The three-letter code in the middle of each sample name indicates its geographical region of origin (see Additional file 1: Table S1 for additional sample details). Samples under a broad dashed line were determined to be intra-taxonomically admixed (pipiens and molestus only). Samples under a fine dashed line were determined to be inter-taxonomically admixed. Within the pipiens and molestus samples, three broad geographical clusters are defined: North America, Mediterranean and northern Europe (including Russia)
