It is a skink rather than a legless lizard as the head is distinct from the body.
The local Leristas are strongly marked with visible stripes bar one and it is round and robust with the tip of the tail tapering very suddenly.
There are two species of Hemiergis that occur in the area. This genus and have highly reduced limbs and no external ear opening. The South-western Earless Skink (Hemiergis initialis) has 5 digits, yellow to orange-red belly and bluish-grey throat. It occurs in moister areas such as woodlands and rocks. The Two-toed Earless Skink (Hemiergis quadrilineata) Is found on the coastal sand plain, has two digits, a yellow belly and a white throat.
The two species can look very much alike. I would say it is mostly likely a Two-toed Earless Skink (Hemiergis quadrilineata). Can you check the belly or tell us the habitat it occurred in – sandy versus gravelly soil?
