Interesting topic. Another species that come to mind is the black pine. I have wondered what enviromental pressures may have been involved for this snakes appearence.
Another snake would be the eastern hognose. I seen six adult specimens in the field this year from three different county's in Ky. All of these specimens were melanistic. I have seen others from the same areas that were not, but this trait is common. Like the black rat, they the melanistic hogs also start their life as patterned snakes, but as they grow, an ontogenetic change occurs, and those specimens predisposed geteticly to turn black start doing so. Why some specimens in a population go through this color change, and others do not interests me.
