In Pokemon Diamond and Pearl the only way to get/see Riolu is in an egg. You can get the Riolu egg from Riley in Iron Island. You must have an empty space in your party then go through it with him and defeat a few Galatic Grunts. Then you will receive an egg, when it hatches you will have a Riolu. This is the only way to see/own it in the game. I hope this answers your question!
First, you have to have defeated Darkrai. Second, you need to equip riolu with a sun ribbon, and take it to the spring where you evolve pokemon. Then it will evolve into lucario.
There is not a legendary Pokemon, however Riley does give you a Riolu Egg.
No, Dusclops does not evolve into Darkrai. Dusclops evolves into Dusknoir by being traded while holding a Reaper Cloth, while Darkrai is a single-evolution legendary Pokemon.
