DistributionAustralia (CE Queensland: Magnetic Island)

Type locality: Magnetic Island (19°08’S, 146°50’E)  
Reproductionoviparous 
TypesHolotype: QM J 24448 
DiagnosisDiagnosis: “Differs from all other Menetia in the following combination of characters: frontoparietals and interparietals fused; pretemporals two, and upper palpebrals enlarged. Description.-Squamation generally similar to M. koshlandae but apparently differing as follows: supraoculars two; transversely enlarged nuchals variable, totaling more than two. In preservative, dorsum of head mottled light and dark brown; dorsum of back and tail light brown; a narrow pale dorsolateral stripe extends from canthus posteriorly onto body; sides of body dark brown; throat pale; venter of body light brown. Details of holotype.-The holotype has paravertebrals 55; supradigital scales 8/9; subdigital lamellae 15/15; presacral vertebrae 31; SVL 22.5 mm; tail length 28.5 mm (7 mm regenerated); sex undetermined.” (Greer 1991)

Comparisons. “Only a few Australian skinks besides the three of the Menetia timlowi species group have the frontoparietals and interparietals fused into a single scale: Carlia rhomboidalis and C. rubrigularis Cryptoblepharus; certain Lerista; and Morethia. The Menetia timlowi species group can be readily distinguished from all these by the combination of four digits on the front foot, and six supralabials with the fourth subocular. Within the Menetia timlowi species group, M. koshlandae is easily distinguished from its two relatives in having small instead of enlarged upper palpebrals, and enlarged nuchals totaling only two (one on each side) instead of more than two (Fig. la-b). Menetia timlowi can be distinguished by having a single pretemporal instead of two (Fig. lc-d), and M. sadlieri by the combination of enlarged palpebrals and two pretemporals (Fig. le-f; see also Table 1).” (Greer 1991) 
CommentAbundance: only known from the type locality (Meiri et al. 2017). 
EtymologyNamed after Ross Sadlier, Australian herpetologist who worked at the Australian Museum from 1979 to 2015.
