Algerian and white bellied pygmies are interbred now with the only difference being that the colors won't blend so the term is referring to a color that mirrors the white belliedfs except has colored cheek patches.
African pygmy hedgehogs are a genus of hedgehog that have been domesticated as pets. In that genus there are two species: white bellied and algerian. Algerians and white bellies have such minute differences and have been bred together for quite a while now. So, algerian refers to a color variation with a large mask and highlights under the eyes and a couple other characteristics, and white bellied hogs have a lighter colored mask and some other differences that are hard to tell apart.
So, chances are your hog is both an African Pygmy and Algerian
