Are you a scientist that works on the nomenclature? Serious question. You're quite defensive. I'm no scientist but I'm sure that at some point if the scientist keep up the pace that they're on, every cichlid will have its own genus. Every minute color variation or subtle body difference will create a new species and probably a new genus then rinse and repeat. I really think that they need to leave well enough alone. It's getting ridiculous.I don't think I know what you mean. DNA evidence doesn't blur the lines, it makes them transparent.
