Riolu evolves into Lucario when it is leveled up with high friendship during the day.
Riolu is #447 in the National Pokedex, and was introduced in the Generation IV Pokemon titles (Diamond, Pearl, and Platinum) where it could only be found by hatching the egg received from Riley. In Generation VI (X and Y), it can be found on Route 22, or through a Friend Safari.

Here's some information on how to make it evolve in Pokemon Diamond Version:
Riolu will evolve at any level during the daytime if it's happiness is maxed. To raise a Pokemon's happiness keep it in your team fully healed for a while. You can also take the Pokemon to a NPC that will groom and massage it to further raise it's happiness.
