Yanma can sometimes be found on Pokemon Diamond, Pearl, and Platinum in the Great Marsh in Pastoria City. You could also catch and evolve a yanma from HeartGold or SoulSilver (found on Route 35 during a swarm) and trade it over to your Pokemon Diamond version. Yanma evolves once it learns AncientPower. You can obtain yanma on Firered or Leafgreen version in Ruin valley and migrate it over to your Pokemon Diamond, Pearl, or Platinum version have it learn AncientPower...and there you have it, you're very own yanmega.
