Tupinambis is a lizard genus which belongs to the family Teiidae and contains eight described species. These large lizards are commonly referred to as tegus (teiús in Portuguese). T. merianae (Argentine black and white tegu), T. rufescens (red tegu), and T. teguixin (gold tegu) are popular in the pet trade. They are primarily found in South America, although T. teguixin also occurs in Panama.
In 2012, a number of tegu species were reclassified from Tupinambis to the previously used genus Salvator. The newly proposed classification comes from a restructuring of the family Teiidae based upon the study of 137 morphological characteristics. The new classification is as follows: Salvator duseni (yellow tegu), Salvator rufescens (red tegu), Salvator merianae (Argentine black and white tegu), Tupinambis teguixin (gold tegu), Tupinambis longilineus (Rhondonia tegu), Tupinambis palustris (swamp tegu) and Tupinambis quadrilineatus (four-lined tegu).[1]
