Caustic and Sanguine leaders just seem to be Ancient versions of Fire and Lifesteal respectively.

Also, it seems like each enemy can only become certain leader types - in the Void, I've only seen caustic and lifesteal Ancients, Guardian and Blast MOAs, and lifesteal, ice, and fire Heavy Gunners. Might be worth keeping track of what each enemy can turn into.
