I would love a link to any research or proof of North American / Asian crosses.
It appears that the cladistic tree is being rewritten here in NA; it almost sounds like you could call the whole NA group "North American Rat Snakes", although that wouldn't appear applicable to their behaviors, diets, etc. Think convergent evolution when comparing New and Old World snakes!

Last I read in the journals, the one snake that ties kings, milks, gophers, corns, and rats together is the Long-nosed Snake, which, based on cytochrome B analysis, shows it to be the colubrid most closely related to what was the common ancestor of them all!

Still, i have not heard of an NA/Asian hybrid and am curious...
