Subspecies
Common Names	E: Large-disced Litter-skink
Synonym	Lygosoma aeratum GARMAN 1901: 7 Ablepharus heteropus GARMAN 1901: 9 Lygisaurus aeratus — INGRAM & COVACEVICH 1988 Lygisaurus aeratus — COGGER 2000: 538 Carlia aeratus — STUART -FOX et al. 2002 Carlia aerata — COUPER et al. 2005 Lygisaurus aeratus — DOLMAN & HUGALL 2008
Distribution	Australia (Queensland) Type locality: Cooktown, Queensland
Reproduction	oviparous (phylogenetic imputation, fide Zimin et al. 2022)
Types	Holotype: MCZ 6476
Diagnosis	Diagnosis: L. aeratus is a large (maximum SV length 39 mm) Lygisaurus with a moveable eyelid con taining a large disc. It can be confused with L. rococo from which it may be distinguished by ear lobules (in L. aeratus, many sharp lobules vs in L. rococo, 1-5 flat lobules), supralabials (6, occasionally 5, with 4th or 5th entering the eye vs 1, with 5th which is grooved, entering the eye), and midbody scale count (19-24 vs 27-30), number of scales between chin and vent (43-54 vs 51-59). Some spirit specimens of L. aeratus can also be confused with specimens of L. foliorum (Ingram and Covacevich, 1988: 340).
Comment	Apparently not listed in COGGER 1983.
Etymology	Presumably named after the Latin aeris (bronze/brass) plus the suffix -atus (made of), relating to the coloration. (G. Shea, pers. comm., 9 Feb 2024)
