It is a gender difference being added retroactively. If you look at the Pokédex page on the pre-release screenshots on Serebii, you'll see each Pokemon has an entry that says "Number of its forms you've registered." I think every Pokemon in the game will have gender form differences in order to give you more reasons to go back and catch more of the same Pokemon as part of your survey research.
