You right , these should be considered sub-species, the Granarius is the
exception here , all the other "forms" have the same structure but the
Granarius is very different. since there is very little taxonomy work done
there would be no real way to know.
 Galapagos tortoises are distinct in that the separate species have varied
carapaces and there habitat DOES NOT overlap, after all if they leave the
isle they become submarines.....just a thought. BTW, did you know that there
are finches on the Galapagos that are  hemovorius , this occures no where
else in the world .
