I didn't notice it during game creation, but I had two terran races in the list and on the map. One was called "New Race" or something close, like the above SS shows. I only noticed it because they were created right next to each other. The map had two systems, each with Earth and Mars, right next to each other.
One system was probably populated only by people with slightly sinister goatees...
Game was on a small map, all races including like 8 custom, scattered, all other defaults I think.
