For those with an interest in Mexican forms of triangulum, here are pics of recent animals from the field. All were taken in the Jalpan Valley of eastern Queretaro. These two live animals, in addition to 3 DOR's (one of which is pictured), nicely illustrate the range of variation within this subspecies.

DOR, quite obviously.

2 ball pythons (lazlo and izzy)
1 amelenistic corn snake (maizy

This animal is a "DOR". It is a term commonly used by collectors in the field, indicating that an animal was found dead on road.

Those are some spectacular animals Bob! Thanks for sharing the beautiful pictures as well. Did you happen to come across any other triangulum while you were there? Shannon probably wasn't joking and I am sure he was drooling for most of the night as well...LOL.

Nathan:

No other triangulum observed, but we were not within the ranges of other forms, aside from annulata, and then only marginally. Our focus was on mexicana-complex snakes: thayeri, mexicana, and ruthveni. I will post some additional pics of that material on the mexicana forum in a couple of days when I return. To me, the impressive thing about these dixoni (and the 2 DOR's not shown) is the great variation evident in pattern within a relatively small area (they all came from the same river valley). The two live ones really don't look much like each other at all.

cheers,

Bob

Nice pics, Bob. Thanks for treating the rest of us to your most fortunate opportunity to see these in the wild.
