This is my personal checklist for Indo/Merauke/IJ.
A very pure Indo should have:
- Inky-black front legs
- Dark spider-web outlining on the top of the head
- The bands should be thin and undefined and one-color
- The body should be long and skinny
- The back and tail should appear very mottled
- Colors of silver/yellow/brown with black bands/speckles

- One stripe down back of neck
- The bands should be thin and defined and one/two colors

So that's my definition of the classic forms of Indo/Merauke/IJ. Going by this, I believe Zergling is pure Indo, while Creep falls between Merauke/IJ but closer to Merauke.
The thing that complications IDing is there are two more recent looks to these types of skinks. There's what we've been calling the New Merauke (Creep falls into this), and there's the Halmahera Indo.
The New Merauke is a Merauke that seems to have more IJ traits. Basically they're a bit more colorful and the bands are thicker than on a the older Classic Meraukes that used to be found. This type is somewhat confusing for me, but there are some stunning example that people on this forum own. I would say Creep falls into this group.
These would probably fall into the New-Merauke group too, but I admit I get confused IDing them:

The Halmahera Indos are quite new, and are pretty easy to distinguish from Classic Indos. They've got dark 'warpaint' marking on their faces, the bands are very thick and dark, and they're not very mottled. I don't have any photos of ones currently for sale, but do a forum search on Halmahera and you'll see some.
