Lygosominae is the largest subfamily of skinks in the family Scincidae. The subfamily can be divided into a number of genus groups. If the rarely used taxonomic rank of infrafamily is employed, the genus groups would be designated as such, but such a move would require a formal description according to the ICZN standards. Egernia group * Corucia – Solomon Islands skink * Cyclodomorphus * Egernia – (paraphyletic: including Bellatorias, Liopholis and Lissolepis, which are better regarded as distinct) * Tiliqua – blue-tongued skinks Eugongylus group Mabuya group Sphenomorphus group
