My thoughts are that I would probably recommend leaving the determination of sub-species up to the professional taxonomists. Unless you have some DNA evidence or collected them yourself I would not be trying to split up a species. If people want to breed what they think are specific locale tincts that is fine. But please keep in mind until they are officially designated as sub-species they are just Dendrobates tinctorius period. Again as long as people in the hobby realize that no Conservation Organizations are going to be knocking on the door of their Arks anytime soon asking for frogs for reintroduction programs. This is just my humble opinion and it is not in an effort to upset anyone.
