Really cool new lizard species x2

These two newly discovered lizards from Peru are some of the neatest-looking lizards on the planet: they could have been used as dinosaurs in those cheesy horror movies of the 50s where they used normal creatures "blown up" optically (and sometimes blown up physically by the heroes). (I'm looking at YOU, Giant Gila Monster.)  What's scientifically interesting is that these two green-brown-black-patterned reptiles share the same range except for a slightly divergent preference in altitudes. It doesn't take a complete separation, it seems, for one species to evolve into two.
