Hi Doug, color and pattern migrate very quickly. So to judge geneflow based on one looks like another is naive.
ALso geneflow is a funny concept when the types of animals are physically seperated by unsuitable habitat and have been for tens of thousands of years.
Mexicana are clearly a mountain island species. that is they occur at higher elevation seperated by low unsuitable valleys.
Ruths, mex mex, thayeri, pyro, zonata, greeri, are all elevation species, a few places zonatas occur to sea level.
Alterna occurs in both montane and low elevation rocky habitats
All these types are seperated by unsuitable habitat, so gene flow currently is not going to occur.
The geneflow concept is really outdated with many many species.
But your right over millions of year, we have no idea what will occur, or even what has occurred.
I once built a timeline exhibit. It was 67 feet long. Man has only been on earth the last 1/4 inch.
