This largest and most diverse family of lizards contains more than 1,275 species in 85 genera; of these, some 389 species and 38 genera occur in Australia and make up about 50% of our total lizard fauna. The family is represented in all tropical and temperate regions, although it is most speciose in the region encompassing Africa, southern Asia, the Indo-Australian Archipelago, New Guinea and Australia.
A recent proposal by Hedges (2014), based on a molecular phylogeny, to split Scincidae into 7 separate families (5 of which would include Australian representatives) is not followed here. A second analysis based on "data from 10 nuclear genes for 17 ingroup taxa and 44 genes for 12 taxa" by Lambert et al. (2014) found Scincidae to be a monophyletic group, probably comprising 3 subgroups at level of subfamily.
Characterised in Australia by: limbs variable, ranging from well-developed pentadactyl forms through various stages of limb and digit reduction to snake- or worm-like forms in which limbs are entirely absent; eyelids either movable or fixed, the latter either forming a complete, sealed spectacle or with a slit-like opening above; pupil usually circular, sometimes vertically elliptical; external ear opening either present or absent; body scales usually imbricate, rarely juxtaposed; tongue broad, flat and fleshy, slightly notched in front; scales on top of head usually enlarged to form a series of symmetrical shields.
