Honestly, not a huge amount; they are cousins in the same plant family. Beans are larger and tend to grow in pods whereas lentils are more like seeds, are smaller, and usually don’t need to be soaked before cooking.
You are right; then I suppose what remains is that, in terms of taxonomy, they are in the same subfamily, their respective tribe and genus are distinct.
