Dead spider in Semuc Champey

So it turns out that this spider isn't actually dead. The wasp is a tarantula hawk, which stings tarantulas, paralyzing them. The tarantula hawk then lays its eggs inside of the paralyzed tarantula, drags the paralyzed tarantula somewhere safe so that the eggs can hatch, and then the young wasps feed upon the tarantula until it dies.

What is that eating the spider? Wasp? Semuc Champey, Guatemala.
