|Diagnosis||DIAGNOSIS: 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 37.4 mm, maximum 46.5 mm SVL), depressed body and head, snout short and narrow with slightly swollen nostril region, top of rostral weakly curved, upper postnasal smaller than lower postnasal; postnasals ~half the size of supranasals; 0–1 small internasals; nostril surrounded by rostral, supranasal, 2 postnasals and first supralabial; 8 or 9 supralabials, first supralabial slightly taller and narrower than second; mental elongate with straight sides and penetrating to 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 10–19; reddish-brown background colour, dorsal pattern with short transverse pale and dark bars or spots not in contact; canthal, loreal and temporal stripes present, 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. peninsularis sp. nov. by less elongate body shape, spots on dorsum smaller with pale spots tending to form transverse bars, canthal stripe darker, and scales on chin more pigmented; from G. media sp. nov. by smaller body size, narrower snout and spots tending to be ordered in rows with pale spots lacking dark edging and often forming transverse bars; from G. fenestrula sp. nov. by smaller body size, narrower snout, fewer supralabials and subdigital lamellae, 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 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 smaller body size, narrower snout, fewer subdigital lamellae, more numerous pre-cloacal pores and lacking dark reticulum on dorsum.
|Comment||Distribution: not in the central and western portions of the Hamersley Range and also the Burrup Peninsula near Karratha where it is replaced by G. peninsularis. See map in Doughty et al. 2018: 8 (Fig. 3).|
|Etymology||Micra is derived from the Greek mikros meaning small. Used as an adjective.|
