The supposed border is indirectly questioned by the molecular data Thomas referred to.
I wouldn't bet too much on morphology, let alone colouration, as reliable to distinguish them.

At least, if you'd find a hatchling with a green throat within the viridis distribution, it might very likely be that it's bilineata or influenced by it.

Has this been investigated across the entire range of both taxa? Even then, I wouldn't be surprised to see this rule violated...
In the end, even assuming that it would be reliable, I think we can agree that it's of limited practical use, right?
