I removed this statement:
"The subfamily Acontinae presently holds only this genus. As the Scincinae are apparently paraphyletic, this might eventually change.(Austin & Arnold 2006)" - because if this was ever the case it does not seem to be now, this paper at least states that there are 3 genuses in that subfamily  
"The endemic southern African fossorial subfamily Acontinae (comprising the three genera  Typhlosaurus, Acontias and Acontophiops)"
