There are a lot more than two types of nerite. I currently have in my main tank a zebra nerite, a 'red onion' nerite, a wagaiensis nerite, a Clithon nerite, a black military helmet nerite, a king koopa nerite; and a Clithon nerite in my shrimp tank.
I don't have an olive nerite - yet.
I haven't used their Latin names as they vary according to which website I look at.
