| Distribution | Australia (Western Australia: only known from two locations 30 km apart in the north-eastern Pilbara near Shay Gap, north of the De Grey River) Type locality: 47.5 km east–south-east of Goldsworthy, site PHYC03 of the Pilbara Biodiversity Survey (2025′41′′S, 11958′10′′E), WA. |

| Types | Holotype: WAM R161461, an adult male collected on 1 October 2005 by A.H. Burbidge and C. Stevenson. Paratypes. WAM R108368 (male), Sunrise Hill (2027′39′′S, 12002′54′′E); WAM R108420 (male), Nimingarra (2026′11′′S, 12000′39′′E); WAM R156584 (male), Cundaline Gap (2033′28′′S, 12010′55′′E); WAM R161459 and WAM R161460 (females), as for holotype. |
| Diagnosis | Diagnosis: A small-bodied (to 39.0 mm SVL) species with moderately short snout, internarial present (67%) or absent (33%), lower postnasal larger or equal to upper, two pairs of chin shields, second infralabial notched by parinfralabial scales, usually six (occasionally seven) subdigital lamellae on the fourth toe and males with 11–13 (mean 12.3) pre-cloacal pores. In preservative, background colour light tan to medium brown with crescent-shaped dark brown bars with pale spots posteriorly, crown with pale white spots, usually poorly defined head stripes and ventrum with only light stippling towards lateral edges. Genetically diagnosed from other arid clade members by the ND2 sites presented in Table 3. |
| Comment | Similar species: The patterning tends to overlap that of G. punctata, but the greyish background colouration of G. unguiculata sp. nov. is different than the reddish hues in G. punctata, possibly as an adaptation to the greyer colour of granite outcrops in the northern Pilbara vs the reddish ironstones that are more common elsewhere in the Pilbara. Distribution: see map in Kealley et al. 2018: 4 (Fig. 1). |
| Etymology | Unguiculata is Latin (diminutive) for fingernail (or claw) and refers to the resemblance of the dorsal pattern elements of this species to small fingernails. Used as an adjective. |
