DiagnosisDiagnosis: A Gehyra with moderately small body size (~50 mm, range 40–57 SVL), no flap of skin between limbs, dorsal half of rostral deeply furrowed with groove, single internasal usually present, 2 postnasals usually similar in size but if different then upper larger than lower, first supralabial slightly taller and narrower than second, 2 pairs of chin shields, first digit of manus and pes without claw, moderately flattened snout, snout straight to concave in lateral view, 7 divided subdigital lamellae on fourth toe, in adult males an average of 15 pre-cloacal pores (range 12–19) arranged in chevron pointing anteriorly. In life, moderately dark tan to brown background colour with pale and dark moderately large spots of similar size and not in contact on dorsum that tend to form transverse rows or coalescing to form short bars. 
CommentHabitat. This species has been collected from sandstone rock formations in open woodland habitats, appearing to prefer large expanses of exposed sandstone such as large boulders and rock walls. It is sympatric with G. nana and G. koira (australis group) at northern localities. The former is a smaller-bodied species that is more commonly found on smaller boulders and amongst rock rubble, whereas G. koira is much larger and prefers boulders and vertical crevices.

Distribution: see map in Doughty et al. 2018: 203 (Fig. 1). 
EtymologyThe specific name paranana refers to the morphological similarity of this species to G. nana, as in “parallel to nana”.
