It's Charles (Chuck) Nishihara actually
Part of the problem I think comes from how these frogs got into the hobby... via europe, wild imporations, both, or one morph one way, the other morph another? Are they like the sips, in which we kept seperate and the forms have bred to the point of more regularly producing like animals? Are they acutally from different parts of an extended wild population? Similar can of worms to Alanis/Inferalanis... there are color/body differences in them too, but does that mean they are different?
We could argue GO/Regina, Alanis/Inferalanis, Blue/Green Sips all day long. We don't know, and likely will never know. Keeping them seperate is a better safe than sorry scenario. They are walking the line of lumping/seperating.
