I am by far not an expert, so please wait for them to answer. BUT, in the meantime I can show you pictures of my Irian Jaya (Tiliqua ssp) and Meraukes (T. g. evanesence). I think most of the identification comes from the foreleggs, because the striping on the skinks in your pictures do look a lot like Merauke striping.

My T. g. evanesence, Anakin:

Good luck, and hopefully someone else can give you a better answer soon!
