This is yellow phase B. colombiensis(asper) from Venezuela.

While they are considered asper, WW indicated that their DNA sugggests a closer relation to atrox.

Now all you need are a few jararaca's, a jararacussa, and some insularis for the collection.
I'm gonna start calling you Mattabuey "bothrops" Harris.

Looks like a washed out asper to me.
What do you mean WW thinks it's DNA suggests atrox?
I thought DNA was exact.

Nah, they look more atrox like to me. This pic shows more of a contrast with a normal snake.

FYI, I didn't take this pic.

DNA is fairly exact, but it's interpretation isn't. Basically, if you look at mtDNA structuring in the B. atrox complex across S. America, you get lots of variability. Al the S. Americans I have tested come out as separate from C. American asper. However, whether or not they are all just one species (B. atrox), or whether there is a whole bunch of undescribed species, is something you cannot tell from mitochondrial DNA sequences alone. I'm working on it...
