This greeri was found by Gustavo Ernesto Quintero Diaz, and his team of biologists from Universidad Autonoma de Aguascalientes, back in 1998. It's one of three greeri they found in Aguascalientes. These snakes were an exciting find because they extended the range of greeri dramatically; none had ever been found in this state before. The area they were found in is midway between Durango and SLP. This one is kinda different looking.

Thanks for sharing.

Of the three mentioned, Is this the only one that is different from what we would expect to see? How did the other two compare? Did either of them also have a lighter ground color? Did either of them also have the cheek-spot behind the eye?

Interesting stuff. I am also curious to know if they were all three found within a reasonably specific area, or if there was considerable distance between them.

Great looking snake Dan.
It looks like some Greeri / Thayeri crosses I have seen, but I know it is not. The spot on the cheek behind the eye is usually characteristic of Mexmex, but again it is not.
How was this one keyed out to be Greeri, taxonomically speaking that is?
Don't get me wrong...it DOES have a dominant Greeri "look" to it.
I appreciate you sharing this pic and info Dan. Keep them coming I am sure others enjoy it as much as I....LOL

Wow, great looking find and interesting greeri.
Is it true no more snakes can be imported from Mexico?
Seems like there's alot going on and more studies are warranted including taxonomy and possibly new species or possible intergrades are yet to be discovered.
Happy Herping,

I'm not sure how the scalation keyed out compared to Durango specimens. But basically, it's identifiable as a greeri by its morphology. DV

In my honest opinion....we have a lot to learn still down south across the border....Am I right?
Theoretically, I think there are possible intergrade zones....even with separation of mountain ranges and habitats. Snakes DO NOT know how to read maps (quote from bluerosy...LOL).
I cannot wait to see the "new" Mexicana....I wonder if it will EVER hit the market as a snake we can have and breed??????????

Tell us how it is possible to actually bring specimens from Mexico into the United States Dan....Is it possible? I thought Alan Kardon from the San Antonio Zoo had specific rights...Am I wrong or not?

As far as I know, there are no living specimens of this new mexicana that Rob Bryson found. I believe there are two "pickled" specimens.

To collect herps in Mexico you need a permit from the Mexican government. Then you probably need an export permit to get them out of Mexico, then an import permit to get them into the US.

Not sure about Alan Kardon. But I suppose most zoos have a better chance of securing a permit than Joe Snake Collector.
