There are a lot of new aliens in the last three Star Wars movies, but very few known species from the Lucas's movies.
In Star Wars VII, we can see Admiral Ackbar (Mon Calamari), Nien Numb (Sullustan), Chewbacca (Wookiee). In Rogue One, we have Admiral Raddus (Mon Calamari) and an ugly twi'lek in Saw Guerrera's base. I don't think I've seen another alien coming from episodes I-VI.
In any of the Disney movies, are there any species present from the pre-Disney movies?
Humans don't count.
