Tegu's anyone?

[Katatonic]

All I have ever read was that there were two integrades of tegu in Argentina; the BW and the Reds, both attaining a large overall size, then there were the smaller Colombian BWs and the Black & Golds as well as a number of other species distributed throughout South America.
I've gathered this information from past REPTILES articles, which very well could be outdated and reclassified as of present, and from other publications stating two distinct species of Red.
If you review the November 2002 issue of REPTILES magazine, which features an article of the captive husbandry and breeding of tegus, the famed tegu breeder Bert Langerwerf goes through classification of the species and their natural ranges: the sixth species he listed was "T. rufescens: the red tegu; from eastern Bolivia, Western Paraguay and central West Argentina as far south as Neuquen".
The animal I was sold was marketed as "Paraguayan", though I am aware of how untrustworthy the common names of herps can be. If the name was mislabelled, I really don't feel as if I was ripped off, as I paid money for a beautiful, high quality, captive bred baby tegu. What I do know is that I was sold the latin name known as Tupinambis rufescens, and going by what Langerwerf states, you could call it either an Argentine, or a Paraguayan and it's overall length would depend on the locale of the originating bloodline.

Your classification would prove right, Snakemann.
