Hi Tom, Hi Mark.
 
I am not a respected malacologist..heck, I'm not even a disrespected
one..but I share Tom's idea. Why wouldn't subspecies appear in the same
area as parent species..or at the very least in overlapping areas?
Subspecies apparently share some of the same characteristics as the
parent species..I can see where geographical separation could have
caused some of the evolutionary differences that would split them into
subspecies, but there must be some common link or why would they be
designated subspecies instead of new species?
