Lygosominae

Lygosominae
	Unidentified Eutropis species from Wayanad (Kerala, India)
Scientific classification
Domain:	Eukaryota
Kingdom:	Animalia
Phylum:	Chordata
Class:	Reptilia
Order:	Squamata
Family:	Scincidae
Subfamily:	Lygosominae; Mittleman, 1952

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.^[1]

Also, several Lygosominae genera were notorious "wastebin taxa" in the past, with scientists assigning more or less closely related species to them in a haphazard fashion and without verifying that the new species were close relatives of the genera's type species. What was once placed in Lygosoma, for example, is now divided among some 15 genera. Similarly, Mabuya and Sphenomorphus are having species moved elsewhere even today.^[2] Obsolete genera include Euprepis.

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

Bassiana (= Acritoscincus) – "cool-skins"
Carlia – four-fingered skinks
Cryptoblepharus – snake-eyed skinks, shining-skinks
Emoia – emoias
Eugongylus – mastiff skinks, short-legged giant skinks
Lampropholis – Indo-Australian ground skinks
Leiolopisma
Niveoscincus – snow skinks, "cool-skins"
Oligosoma

Mabuya group

Chioninia – Cape Verde mabuyas (formerly in Mabuya)
Dasia — Southeast Asian tree skinks, including Apterygodon (now considered to be part of Dasia)
Eumecia — Central African elongated skinks ^[3]
Eutropis – Asian (formerly in Mabuya)
Heremites — Mediterranean (North Africa and Middle Eastern species) ^[3]
Mabuya – American mabuyas
Toenayar — composed of a single species in India/Indochina ^[3]
Trachylepis – Afro-Malagasy mabuyas (formerly in Mabuya)

Sphenomorphus group

Anomalopus – worm-skinks
Ctenotus – comb-eared skinks
Eulamprus – water skinks
Glaphyromorphus ^[4]
Gnypetoscincus – Prickly Skink
Insulasaurus ^[4]
Lipinia – lipinias
Otosaurus ^[4]
Parvoscincus ^[4]
Pinoyscincus ^[4]
Scincella – ground skinks ^[4]
Sphenomorphus – common skinks (paraphyletic) ^[4]
Tytthoscincus ^[4]

Undetermined^{[verification needed]}

Eremiascincus
Hemisphaeriodon – pink-tongued skinks
Lamprolepis – tree skinks
Lerista
Lobulia
Lygosoma – writhing skinks
Saproscincus – shade skinks
Tribolonotus – crocodile skinks (Egernia group?)

"Hinulia" elegans, described by Grey in 1838, is unidentified, but may be Eulamprus tenuis.^[2]
