Ctenotus is agenus ofskinks,lizards in thefamily Scincidae. The genus isendemic to Australia. The genusCtenotus belongs to aclade in theSphenomorphus group which contains suchgenera asAnomalopus and the close relativesEulamprus andGnypetoscincus.[2]

Lizards in the genusCtenotus are commonly calledcomb-eared skinks, a reference to the scales aligned near the ear.[3]Ctenotus lizards are able to move very quickly, disappearing whilst being observed. They are highly active in their habits, foraging amongst a diverse range of habitat.

The members of the genusCtenotus are widelydistributed, in all states ofAustralia, and are especially diverse in arid regions and thetropical north, accounting for 10–20% of the lizard species. Around a quarter of lizards found in one area of theGreat Sandy Desert areCtenotus skinks, 11 of the 40 species.[3] A single dune may have up to six species ofCtenotus. TheSouthwest Australian region contains 23 species. The size ranges from very small to moderately large, being similarly varied in body types from slender to stout.[4] The diversity of forms allows species to occupy differentniches, often in the same locality.[3]

Species

[edit]

Ctenotus is the most diverse reptile genus in Australia, with approximately 100 member species. Identification to the rank of species is regarded as difficult, and the largest lizard genus is also one of the most poorly understood.[4][5]

Nota bene: Abinomial authority in parentheses indicates that the species was originally described in a genus other thanCtenotus.
