Why the DR 5/evil ?
As to the CR, it looks slightly harder than a zombie due to the special attacks I'd say CR should be something like 1 more than a zombie of the equivalent creature.
I'm using a new keyboard so there are a few typo's.
Ribwalkers are pumped full of negative energy to the point where they have a glow and their eyes can poison you, some demons aren't even that evil
Changed the CR.
