Higher TaxaGekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)
Common NamesE: Medium Pilbara Spotted Rock Gehyra 
SynonymGehyra media DOUGHTY, BAUER, PEPPER & KEOGH 2018: 27 
DistributionAustralia (Western Australia: Pilbara region)

Type locality: Baldy Rock, Pilbara region (21.05°S, 118.80°E).  
Reproductionoviparous (not imputed, fide Zimin et al. 2022) 
TypesHolotype: WAM R162687, adult male, collected by P. Doughty, C.A. Stevenson and P.G. Kendrick on 15 May 2006. Paratypes: Australia: Western Australia: WAM R160940, male, 9 km northwest of Lake Poongkaliyarra (20.9399°S, 118.0640°E); WAM R161014, female, 3.5 km south of Marda Pool (21.065°S, 116.150°E); WAM R162686, male, as for holotype; WAM R162704, female, as for holotype; WAM R174289, female, Nanutarra Roadhouse (22.46434°S, 116.03714°E). 
Differs from non-Australian Gehyra by lack of extensive webbing between toes III and IV, a cutaneous fold along the posterior margin of the hindlimb, and the presence of transversely widened subcaudal scales. Differs from other Australian Gehyra by possessing small body size, moderately narrow snout, weakly gabled rostral, upper postnasal half to 1/3 the size of lower, 7–9 supralabials, first supralabial taller and usually narrower than second, mental long with straight sides, inner chin shields in contact or narrowly excluded with second infralabial, second infralabial notched by encroachment of first parinfralabial, 5 or 6 divided lamellae on the fourth toe (without basal wedge of granules), in adult males 8–15 pre-cloacal pores arranged in a chevron. Dorsal pattern with dark brown and pale spots on light reddish-brown background, spots usually not in contact; canthal and loreal stripes weak, temporal stripe variable expressed, post-orbital stripes reduced to at most a spot, pale zone between canthal and loreal stripes.
Further distinguished from other Gehyra from the region with reddish-brown colouration as follows: from G. punctata, G. macra sp. nov., G. punctulata sp. nov. and G. polka sp. nov. by smaller body size, shorter and more convex snout and fewer subdigital lamellae; further distinguished from G. macra sp. nov. by adult males possessing fewer pre-cloacal pores (8–15 vs 14– 21); from G. fenestrula sp. nov. by dark and pale spots separated (vs joined); from G. micra sp. nov. by slightly larger body size, broader snout and dorsal pattern consisting of scattered spots (vs rows of short bars) and pale spots with dark border; from G. peninsularis sp. nov. by fewer subdigital lamellae (5–6 vs 6–7) and pattern consisting of small spots not in contact (vs large spots tending to form transverse rows); from G. pilbara by longer and more depressed head, longer inner chin shields in contact with first infralabial and spots on dorsum more clearly demarcated from background colour; and from G. montium by fewer subdigital lamellae and lacking short bars (vs spots) or network of irregular dark lines.
CommentHabitat: under small rocks near roadsides, Triodia plain on stony sandy soil, granite rocks, rocky drainage lines, sandplain and dune slope.

Distribution: see map in Doughty et al. 2018: 8 (Fig. 3). 
EtymologyMedia is derived from the neuter of medius, meaning middle, in reference to this species’ intermediate size between G. micra sp. nov. and G. macra sp. nov.
