I been thinking it could also be a new species along with the reasons Dracosaurian said. It is recently discovered and its invasion is so wide spread so I think it may be a new species. That or just a complete horror invasion from another continent or Island, it had to come from somewhere.

Kinda like Abiorugu was the first Brute Wyvern known in the Old World. Originaly it was a member of the even further undiscovered at that time Giaorugu who made its way to the rest of the Old World and changed into the green new species Abiorugu who also became wide spread.
