Doug's letting it out! LOL I agree with his ideas on the subject.
Those animals show "intermediate" characteristics as far as banding is concerned. What is traditionally known as 'sinaloae' has fewer [=wider red] bands than 'nelsoni'.
As to whether the ranges "overlap"... I'd say no. No two primary subspecies ranges "overlap" in nature. There is an area of non-differentiation, but no "overlap". Primary subspecies did not diverge allopatrically and then re-unite (overlap), but diverged into different ecological niches and remain undifferentiated in transitional habitat areas. There is a lot of misconception regarding subspecies and zones of intergradation. I hereby declare myself the crusader of misconception of the subspecies concept! LOL
Gorgeous animals, by the way.
