Add a New Pathfinder Race
From D&D Wiki
To make a new page for you own race, simply replace "MyRace" in the field below. (Make sure the name of your race is in plural form; e.g. "Elves" instead of "Elf.") Please leave the " (Pathfinder Race)" indentifier. Then click the button and you'll be taken to an edit page with a template and instructions for adding your creation. If a race already exists by the name you submit, you'll be taken to the Edit page for the existing race.
You can check out this official Race Building guide for advice on creating a race and working out how to balance it.
