good question.......
There is some pretty good info indicating that they are the same species with a distinction at the subspecies level.... think bull snake and sonoran gophersnake.
I know that there is a pair of them in Europe... Germany I believe, and we are working with 1.2 of them with Guatemala locality. (think good thoughts and maybe there will be offspring available in 2010!!!!)
Given the small sample size of these guys and the nominant form for that matter I can not really make anything but generalizations on how they differ. Most of the literature suggests that they differ via geographic distribution, but also gibson's line-necked pinesnakes tend to have dashed dorsal neck lines where as the nominant form have solid neck lines.......
the ones I have seen have a nice pale chocolate ground color. A fellow I know who sees them often described seeing a road killed adult that had a striking burnt orange ground color.... unfortunately that was not the norm....
here is am image of a P.l.gibsoni
