taking from each bestiary, AP, and the Advanced Race Guide, not counting the "Monstrous" and "Very Powerful" options of centaur, ogre, shobad, drider, and gargoyle, and also not counting the variant races/subspecies of aasimar, tiefling, dhampir, and skinwalker as separate races, I have compiled the following list;
1. Aasimar
