Well, judging from the fact that elves are considered a race rather than a species in fantasy literature, I think the Guado would also qualify as a race. I see no references to Ronso and humans interbreeding, however, so they would probably qualify as a species. That said, I’m not 100% clear on what the exact difference between races and species is, but seeing the Al Bhed referred to as a species irked me, so I had to speak up.
