|Distribution||Australia (New South Wales, Queensland)|
Type locality: Mt Coot-tha, Brisbane, Qld.
|Types||Neotype: QM J23660, collected C. Morris & A. Merrit, 22.vii.1973. Designated by Ingram & Covacevich (1988). Holotype: QM presumed lost, see Covacevich (1971).|
|Diagnosis||Definition (Lygisaurus): The clade comprising Lygisaurus foliorum de Vis, 1884, and all organisms or species that share a more recent common ancestor with Lygisaurus foliorum than with Carlia munda or Liburnascincus coensis (DOLMAN & HUGALL 2008).|
Description (Lygisaurus): A genus of the Carlia group of skinks, maximum adult SVL ranging from 30 to 39 mm, body and head slender, limbs small to moderately well developed, usually 6 or 7 supralabials, dorsal body scales weakly striate never keeled, sexes similar in colour and pattern but breeding males in some species develop reddish colouring confined to the head or tail, usually 15 premaxillary teeth ([Ingram and Covacevich, 1988b] and [Ingram and Covacevich, 1989]).
Diagnosis: L. foliorum is a large Lygisaurus, with a maximum SV length of 39 mm.
L. foliorum and L. timlowi are the only species of Lygisaurus with the lower eyelid fused (or partially fused) above and with a large trans parent palpebral disc. They are readily dis tinguished from each other by ear size and shape (L. foliorum, smaller than disc with longer axis horizontal vs L. timlowi, very much smaller than disc), ear lobules (present vs absent), supraoculars (4 vs usually 3, occasionally 1 or 2), interparietal scale (free vs fused to interparietal), supralabials (7 or 8, with the 5lh or 6th under the eye vs 6, with the 4th under the eye), midbody scale count (21-25 vs 18-20), and lamellae under the fourth toe (17-23 vs 15-19).
L. foliorum appears to be a sister species of L. aeratus despite the fact that the latter species has a moveable eyelid, a character which may appear to be fused in spirit material and cause confusion between these two species (Ingram and Covacevich, 1988: 336).
|Comment||Type Species: Lygisaurus foliorum de Vis, 1884 is the type species of the genus Lygisaurus de Vis, 1884.|
Phylogeny: Bragg et al. 2018 presented a phylogeny of the genera Lygisaurus, Liburnascincus, and Carlia.
