Na, sorry. Don’t know what they are called in english. And no, I just made something and when I finished thougt about it, what could it be. Sometimes I have no plan.

    Genasi are humanoids and one of their ancestors were a fire Elemental or wind Elemental and so on.

    But it exists as well Assimar and Tiefling. If I translate Tiefling into englinsh, the could be called deepling. Assimar have a ancestor, who was a kind of angel. Angel have an other name in D&D. The deeplings ancestor is a demon or devil. Maybe you can call assimars positive genasi and deeplings negative genasi.
