DiagnosisDiagnosis: L. laevis is a large (maximum SV length of 37 mm) Lygisaurus with a moveable eyelid containing a small disc, a character it shares with L. tanneri, L. sesbrauna and L. macfarlani. Table 1 summarizes features which distinguish these four species. Other characters (midbody scale count, chin-vent scale number, lamellae under the 4th toe, and numbers of scales between the second presubocular and the nasal) arc not use ful in distinguishing the species. Table I emphasises the similarity of these four species. It shows that L. laevis is most difficult to dis tinguish from L. sesbrauna from which it is dis tinguished consistently only by ear shape and size of ear lobules (Ingram and Covacevich, 1988: 344). 
CommentLygosoma laeve is a synonym of Liolopisma novaeguineae (MEYER) fide DAAN & HILLENIUS 1966 and LOVERIDGE 1934. 
EtymologyPresumably named after the Latin levis (smooth), in allusion to the smooth scalation. (G. Shea, pers. comm., 9 Feb 2024)
