Im only saying I agree with it being possibly a new species, going with youre Dog and Wolf example alot of people commonly mistakes Foxes as dogs, so im only saying its possible.

Another thing it sais the "Unknown" Rathian gathers in large numbers in the Desert so there not completely seperate from each other, I can asume its for mating, since I cant think of any other reason for them to gather.
