A morph of Sonoran decent from Hans Winner.  Originally called Mephisto.  Hets can have a different look, and a lot of people look at these as visual hets.  As a breeder who has extensive Leopard experience, with one of the highest number of successful Leopard breedings in the US, I can attest that it is indeed recessive.  The "look" of het Leopards is simply due to their unique locale origin and this look shows up in mixed lineage litters as a carry over of the locality mix.  I have yet to see a "normal" looking boa in a het x het litter, which shows that this "look" is not connected to the mutation itself.
