Back when the first trailer footage came out an Anon, I believe, claimed that there was an Abiorugu Subspecies. I rewatched the trailer over and over until I finally found it.

I am going to assume it is a subspecies since all the other monsters shown were new too so it wouldn't make sense to show an old monster in the trailer.
