Hi there

I'm discussing with some people about the subspecies of the following snakes.

I would say those are L. m. mexicana:

And this one is a L. m. greeri.

What do you think?

First one is a classic L. m. mexicana, typical of those from the Valle de los Fantasmas region of San Luis Potosi.

Second one is problematic, as it has pattern elements suggestive of mex mex but potentially also greeri, and even thayeri. I cannot offer a definitive opinion.

Third one is more or less consistent with greeri. The caveat with this identification is that, not only in the U.S. but more so in European collections, the poor access to breeding material of unquestioned origin has led to the production of numerous animals that are phenotypically intermediate.

Thanx for your answer. I recently found this pic and wonder what it could be. for me it doesn't look like a clean greeri because the pattern do not go till the belly. But the coloration and the build looks like one - so what is it?

Cyrill:

I don't regard this one as beyond the range of normal variation for greeri. Again, it's almost impossible to rule out that something else might be involved along with greeri, but I don't see anything in this animal to suggest that. Neat snake!

Cheers,

Bob

Hi Bob

The reason why I ask is the following. As you know I'm discussing with some people about those snakes. The problem was, he thought / or even think that this one is a thayeri. Because a few years ago someone told this to him. On this way he even think that the third snake in the first post is a thayeri.

If my opinion isn't enough authentic for him, I've got to ask some other people to make him believe. That's the reason for this question. However, thanx for the answer.

Regards from the other side of the atlantic,
