I always wondered what the criteria were for claiming that something was a subspecies rather than a separate species. For example, what exactly is it that makes o. quadrivatta (is it quadrivattUS now? I'm assuming it is, but correct me if I'm wrong) a subspecies of o. obsoletus? Why couldn't it be quadrivattus quadrivattus? Is it that o. obsoletus has the larger range, or are there DNA tests or something?
