If you find one of each (one of one subspecies, one of the other, and an integrade) you are not actually finding all 3. You are simply in a zone of integradation, and all animals found within that zone are integrades regardless of phenotypic appearance.

In a zone of integradation animals can key out phenotypically as one subspecies, as the other, or as a blend of the two (or however many subspecies are integrading in the area), but in all actuality they are all integrades within that area, even if they don't phenotypically show it.

BTW, I love herping NW AR/ SW MO, and like you said you can find the animals that are phenotypically one way or the other in the same areas there, but they are all actually integrades, not one subspecies or the other.
