Type locality: King Edward River, "presumably 14° 52’ S, 126° 12’ E", W. A.  
Reproductionoviparous 
TypesHolotype: WAM R28214, adult male, collected on 8 June 1965 by A.K. Lee; Paratypes (94): WAM, MCZ 
DiagnosisDiagnosis: A Gehyra with small body size (mean 42 mm, range 34–55 mm SVL), no flap of skin between limbs, dorsal half of rostral deeply furrowed with groove, single internasal usually present, 2 postnasals of similar size, first supralabial taller and narrower than second, snout short and convex in lateral view, first digit of manus and pes without claw, mode of 6 (range 5–7) divided subdigital lamellae on fourth toe, mean of 15 (range 10–22) pre-cloacal pores in males arranged in a chevron pointing anteriorly. Background colouration dull light tan to brown with numerous small pale spots or short bars and large dark spots (not in contact) on dorsal surfaces that tend to form transverse rows on dorsum; no dark temporal streak behind eye (Doughty et a. 2018). 
CommentBelongs to the Gehyra variegata-punctata species complex, or more specifically to the G. nana complex that has a number of undescribed species (Moritz et al. 2017).

Habitat. This species has been collected from sandstone and other rock formations in open woodlands. Occurs under large flat rocks on open sandstone platforms as well as rocky creeks and gorges, including scree. Occasionally found on trees, but always near rocky outcrops. It is generally found among small boulders and loose rock rubble, but can occur on larger open rock faces in the absence of larger Gehyra species such as G. koira Horner or G. pseudopunctata sp. nov. 
EtymologyStorr used the word nana (Latin), meaning small, to describe this small-bodied species relative to larger forms of Gehyra.
