Higher Taxa	Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)
Subspecies
Common Names	E: Small Wedge-toed Gecko
Synonym	Gehyra spheniscus DOUGHTY, PALMER, SISTROM, BAUER & DONNELLAN 2012
Distribution	Australia (Kimberley region) Type locality: Lower Monjon Rocks, Prince Regent River Nature Reserve (15.9775°S; 125.3678°E), Australia.
Reproduction	oviparous (not imputed, fide Zimin et al. 2022)
Types	Holotype: WAM R171591* (male), collected on 25 January 2010 by C.A. Stevenson and R. Somaweera. Paratypes: WAM
Diagnosis	DIAGNOSIS: Digits broadly expanded basally and subdigital scansors present on all digits of manus and pes. Digit I of manus and pes clawless or bearing a minute claw, penultimate phalanx of digits II–V free from scansorial pad. Body atuberculate. 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. Differs from Australian species by small (~ 45 mm SVL) body size and a wedge of granules at the base of the expanded terminal pads on the digits; further distinguished from G. xenopus by 6 lamellae on fourth finger and toe, 7 or 8 upper and lower labials, single internarial, ~30 interorbital scales, ~25 precloacal and femoral pores in males in an unbroken chevron and dorsal pattern with transverse rows of alternating light and dark spots or bars.
Comment	Similar species: May have been previously confused with G. xenopus. HABITAT: All specimens were collected from areas of rugged sandstone. Collection notes mention the tops of open sandstone platforms, the top of a large boulder on a high outcrop and one specimen from a tree in a wetland adjacent to a low rocky ridge.
Etymology	The epithet spheniscus (Latinized Greek), meaning ‘a small wedge’ refers to the triangle-shaped wedge of granules on the toe pads. Used as a noun in apposition.
