It's just a guess, but maybe the name comes from Godzilla Island. Apparently on that show, there was an adult Mothra, who had two larvae, a male and a female. The male eventually became the Rebirth of Mothra trilogy Mothra, whom we call Mothra Leo. So, considering there were three Mothras in that series, they could have had different names to differentiate between them. It wouldn't be unusual for Godzilla Island to have given him that name, since they called the Showa MechaGodzilla "Black MechaGodzilla" and the Showa Moguera "Proto-Moguera."

Unfortunately, I don't have access to Godzilla Island or a reliable official database on the monsters, so we may never know.
