This application seems to disagree with this definition of a complex that I was given when the complex option was created, and with “Species sometimes intergrade and there are places on the tree of life where adding hard range map boundaries is arbitrary and/or identification to species level is often not possible.” Species groups can have species where there is no doubt that they are valid species, and are easily separable with a microscope. If we go with this, should the above definition be broadened?
What would we do in a case like this?
