Insect/spider like predator

I haven't drawn enough insect like anythings. At least not from Skatha.

Anyway, this guy burrows down in a tunnel and waits, then zips out and snatches up its prey with its tendrils (not shown). Then it injects a neurotoxin and once the prey has stopped moving it begins to slowly rasp away at it with its lower radula like jaws.
