It can be distinguished from all other members of the genus by the following combination of characters: frontoparietals divided; two loreals, anterior loreal a small semilunar scale positioned off the postero- dorsal edge of the enlarged nasal scale and failing to contact the labials; seven or more upper labial scales; left and right oviduct present in females; lower eyelid “scaled”; ear opening minute; body scales striated; adult dorsal colour two-toned; ear opening positioned four scales posterior to lower secondary temporal; presacral vertebrae 33–34; phalangeal formula for manus 2.3.3.3.3; phalangeal formula for pes 2.3.4.4.3.

CommentThis is the only species of Nannoscincus recorded as being able to vocalise.

Distribution: see map in SADLIER et al. 2014: 56.

Abundance: only known from its original description (Meiri et al. 2017). This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. 
EtymologyThe specific epithet is the Latin word garrulus, meaning talkative, and is in reference to the tendency for this species to emit a squeaking sound when distressed.
