Corruptor

A Corruptor is a new mob coming to Terraria in the 1.1 (or a proceeding) update. It spawns in Corruption, but it seems that it may only spawn underground. It has 400 health as of its debut, and looks like a larger and fancier Eater of Soul. They fly, and move with little agility but with quite a bit of speed. Their defence and attack power is currently unknown.
