Type locality: Dampier Port, Burrup Peninsula (20.6166°S, 116.7500°E)  
TypesHolotype: WAM R165749, an adult male collected by G. Harold and L. Beesley on 26 April 2006. Paratypes: Australia: Western Australia: WAM R132562 (female), WAM R146581 (male), Burrup Peninsula (20.6161°S, 116.7850°E); WAM R165748 (female), as for holotype; WAM R165239 (female), 2.4 km west of Hearson Cove, Burrup Peninsula (20.617°S, 116.772°E); WAM R165240 (male), 3.4 km north-east of Dampier, Burrup Peninsula (20.658°S, 116.741°E). 
DiagnosisDIAGNOSIS: Differs from non-Australian Gehyra by lack of extensive webbing between toes III and IV and a cutaneous fold along the posterior margin of the hindlimb, and the presence of transversely widened subcaudal scales. Distinguished from other Australian Gehyra by small body size (mean 42.2 mm, maximum 48.5 mm SVL), depressed body and head, snout short and narrow with slightly swollen nostril region, top of rostral weakly curved, furrowed medially, upper postnasal half the size of lower; 0–1 small internasals (supranasals usually in contact); nostril surrounded by rostral, supranasal, 2 postnasals and first supralabial; 7–10 supralabials, first supralabial slightly taller and narrower than second, mental elongate with straight sides and penetrating to approximately half the length of the inner chin shield, inner chin shields in contact with second infralabial, first parinfralabial encroaching on second (usually) or third (occasionally) infralabial; fourth finger and toe lamellae 5–6, lamellae divided and lacking wedge of granules at base of toe, pre- cloacal pores in adult males 7–15; light reddish-brown background colour, dorsal pattern comprised of rows of alternating moderately large pale and dark spots, often forming transverse bars; canthal, loreal and temporal stripes present, pale white patch between canthal and loreal stripes and pale bar above temporal stripe usually present.
Further distinguished from other reddish-brown Gehyra in the Pilbara as follows. From G. media sp. nov. by larger spots tending to be in contact and forming transverse bars, and pale spots lacking dark edging; from G. micra sp. nov. by more elongate body shape and spots on dorsum larger, forming thicker transverse bars; from G. fenestrula sp. nov. by deeper head, fewer supralabials, and pale spots tending to form transverse bars with dark and pale elements not in contact; from G. punctata by smaller body size, deeper head, fewer supralabials and subdigital lamellae and pale dark and pale elements of markings not usually in contact; from G. macra sp. nov. by much smaller body size, fewer supralabials and subdigital lamellae, more reddish dorsum and clearly demarcated spots; from G. pilbara by longer and narrower snout, chin shields not very reduced in length and lacking a diffuse reticulum as a dorsal background pattern; from G. montium by narrower snout, inner chin shield in contact with second infralabial and different dorsal pattern: lacking short dark and pale bars and/or dark reticulum on dorsum.
