I doubt it's severus. It's more likely a mis-barred efasciatus/rotkeil or possibly one of the Inirida-like species from Colombia/Venezuela. I have a bunch of Inirida from Colombia that have either a half-seventh bar, a quarter-seventh bar, or sometimes only eight total bars. They're highly variable.
You'll have to grow it out a bit and see what the coloration looks like before you know for sure. Unfortunately Heros are like discus -- individuals can pretty easily be mis-barred with Y or forked/fused bars.
