|Diagnosis||Diagnosis. A Gehyra with moderate body size (average 54 mm, range 47–58 mm SVL), no flap of skin between limbs, dorsal half of rostral deeply furrowed with groove, internasal usually absent, 2 postnasals similar in size, first supralabial taller and narrower than second, 2 pairs of chin shields, snout moderately long and straight or slightly convex in lateral view, first digit of manus and pes without protruding claw, 7 or 8 divided subdigital lamellae on fourth toe, mode of 8 (range 7–11) pre-cloacal pores in males arranged in short shallow curve pointing anteriorly. Background colouration in life dull tan to pinkish-brown with scattered large pale squarish spots and more irregular dark blotches, post-temporal and canthal streaks sometimes present.|
Comparisons with other species. Gehyra pseudopunctata sp. nov. is distinctive in the Kimberley region, owing to its moderately large body size (47–58 mm SVL), divided lamellae lacking granules, relatively few pre- cloacal pores in males and a dorsal pattern of large pale and dark spots on a reddish-brown background. Larger- bodied species of the G. australis species-group possess undivided lamellae. Most smaller-bodied species have fewer subdigital lamellae (typically 5 or 6) and numerous small dark and pale spots (G. nana, G. granulum sp. nov.) and/or more diffuse markings (G. girloorloo, G. spheniscus, G. pluraporosa sp. nov.), whereas G. pseudopunctata sp. nov. typically have 7 or 8 lamellae and much larger and well-defined spots. Species of moderate body size such as G. kimberleyi, G. multiporosa and G. occidentalis tend to have more diffuse markings on the dorsum, smaller spots and more numerous pre-cloacal pores in males (11 or fewer in G. pseudopunctata sp. nov.; most small-bodied species have numerous pre-cloacal pores as well). The most similar Kimberley Gehyra in patterning is G. xenopus that occurs allopatrically in the northwest Kimberley which also possesses large pale and dark spots; however, this species has a distinctive large wedge of granules that divides the proximal lamellae on the undersides of the digits and reaches larger body sizes (62–79 mm SVL).
|Comment||Habitat. Gehyra pseudopunctata sp. nov. has mostly been collected from around large boulders, rock walls, platforms and associated crevices among large sandstone or granite rock formations, similar habitats to the large- bodied G. occidentalis and G. koira from the same region. It is sympatric with the G. nana complex, G. occidentalis and G. granulum sp. nov., and in the west of its range with G. kimberleyi. The species has often been observed running upside down beneath rock overhangs. This habitat differs from the small rock ‘rubble’ habitat typically associated with the smaller-bodied G. nana and G. granulum sp. nov. in the Kimberley.|

|Etymology|| The specific name pseudopunctata refers to the long-standing attribution of this species to the Pilbara species G. punctata. Hence “false [= pseudo, Latin] punctata”.|
