As far as I know, Wraithbane is only found very rarely on ancient items, and allows you to kill Marsh Wraiths.

Wightbane is obtained by killing a lot of Barrow Wights, Gondor Ruins Wraiths, Rohan Barrow Wraiths, Harad Pyramid Wraiths, and Tauredain Pyramid Wraiths, and does bonus damage against all of the mobs previously listed.
