Hypos are Colombians. I've always been a big fan of hypos, I think that would be a great choice.
They're the Latin names, Boa constrictor imperator and Boa constrictor constrictor. There are a number of other B.c. subspecies as well but these two are the most common. Then there are locales within the subspecies. For example, there are Bci that originate from Colombia, Hogg Island, Central America, etc, and the most common Bcc are from Suriname, Peru, Venezuela, and many other places.
