Did it say that it is for sure a subspecies?

Also I didn't say it has to be like that. I just find it would be a pretty creative idea and it does make sense to me.

The sexual dimorphism might be a trait of the Moga subspecies only. So Minegard only has the black Nargacuga being male or female while Moga has a subspecies of Nargacuga that has a female black and a male green what color can be easily explained with their activity to the respective day time.

Btw, also for Gigginox Subspecies there is a theory that it is the male form of Gigginox. I don't think it is but I just wanted to mention it.
