This looks to be Saproscincus sp., however I doubt that it's S. mustelinus as it doesn't have a white spot under/behind the eye. There are a few species of Saproscincus recorded in the area, namely S. rosei, S. challengeri and S. spectabilis. I added Saproscincus sp. to the dropdown menu for cases like this, where it's not clear which species of Saproscincus it is.
