These games are frequently labeled as "roguelike", but also are referred to as "roguelike-like", "rogue-lite", or "procedural death labyrinths" to distinguish them from the more traditional roguelike.

For the longest time game journalists and people on game forums were careful to refer to these games as "rogue-lite", etc., but in recent years it's become more common to just call them roguelikes as well, even though they don't play anything like Rogue/Angband/Nethack/etc. That's fine by me, it feels more like a natural evolution of the terminology than people using the wrong words for things.
