Acontias, the lance skinks, is a genus of limbless 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]

Species[edit]

The following 21 species are recognized.[3]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Acontias.
