Wow I'm jealous; I wish I could go down there. There are actually some bigger types of tegus that aren't even sold here in the US. Maybe you could bring some back
. I'd be interested in one if you do. Especially Tupinambis quadrilineatus; they get over 3 feet long. Maybe you'll consider going to this place in Brazil they have em there.

And of course Callopistes flavipunctatus (fake monitor, monitor tegu, or Peruvian Tegu) from Peru

And you know there are probably other species of tegus yet to be discovered (recognized by science).
