Acontias is a genus of limbless skinks, the lance skinks, (family Scincidae) in the African subfamily Acontinae.[1] Most are small animals, but the largest member of the genus is Acontias plumbeus at approximately 40 cm (16 in) snout-vent length.[1] All members of this genus are live-bearing sandswimmers, with fused eyelids. A recent review [2] moved species that were formerly placed in the genera Typhlosaurus, Acontophiops, and Microacontias into this genus, as together these form a single branch in the tree of life. This new concept of Acontias is a sister lineage to Typhlosaurus, and these two genera are the only genera within the subfamily Acontinae.[2]
