Could be johannii. Some variants of M. johannii have clean solid horizontal lines like M. cyanoerhabdos, some have both vertical and horizontal ones like M. interruptus.
That is the beauty of M. johannii. That and the fact that unless you get them from a reputable source (direct, not from a guy who got them from some guy who said they came from "Stuart Grant's Facility") or at the very least a collection location and you were up to snuff on your Malawi cichlid's geographical origins, the likelyhood of them being hybrids is high. M. cyanoerhabdos x M. johannii is not out of the question.
I personally have stayed away from tankbred Johannii types. If I ever was to get one they'd come from a reputable source with collection location so I could sell the offspring in good consience as a certain species, not the run-of-the-mill tankbred Melanochromis "johannii type".
