Description. A moderately long, attenuate skink with small front and rear limbs and a plain brown colour pattern.
Snout bluntly rounded; rostral with broad, moderately deep median lobe projecting between nasals to make narrow contact with frontonasals; frontonasal wider than long (1.4-1.8 x); prefrontals well developed but widely separated; frontal slightly longer than wide (1.2-1.4 x) and slightly shorter than midline length of frontoparietals and interparietal; supraoculars 4, first 2 in contact with frontal; frontoparietals paired, in contact, each shorter and broader than interparietal; interparietal distinct, with distinct parietal eye spot; parietals meet behind interparietal; each parietal bordered posterolaterally by large upper secondary temporal and 2 to 3 more-or-Iess equally sized body scales; transversely enlarged nuchals 0-1.
Nasals large and separated, nostril situated slightly forward and below centre point; loreals 2, approximately equal in size and proportions; preoculars 2, lower much the larger; supraciliaries 6 to 7, first separated from frontal, penultimate occasionally projects slightly medially between third and fourth supraoculars, and ultimate projects medially between last supraocular and pretemporals; suboculars large and forming a continuous row comprised of 1presubocular, 2 suboculars and 1 postocular; lower eyelid scaly; pretemporals 2; primary temporal single; secondary temporals 2, upper very long and overlapping lower which is about equal in size to primary temporal; tertiary temporal single; external ear opening absent, represented by an anteriorly dipping, shallow auricular crease; supralabials 6 or 7, fourth smallest and situated directly below centre of eye; postsupralabials 2; infralabials 6 or 5; mental large, wider than long (1.7-2.3 x); postmental much wider than long, in contact with first two infralabials on each side; enlarged pairs of chin scales 3, first in contact, second separated by 1 scale row and third separated by 3.
Body scales smooth, in 18-20 longitudinal rows at midbody; paravertebral scales only slightly wider than those in more lateral rows, 97-116 in a single row; inner preanals overlap outer, medial pair enlarged; median row or subcaudals equal in size to immediately adjacent rows.
Snout-vent length 63-123 mm; front leg with 3 very short, clawed toes of which middle is longest, 0.05-0.07 x SVL; rear leg with 2 very short clawed toes of which second is longer, 0.04-0.08 x SVL; tail pointed, 1.03-1.21 x SVL.
Presacral vertebrae 51-58; complete inscriptional chevrons 11-13; sternalimesosternal ribs 212.
Manus comprises radiale, ulnare and pisiform (intermedium could not be assessed); centrale; distal carpals 2-4; metacarpals 2-5, and phalanges 0.2.3.2.0.
Pes comprises fused astragalus and calcaneum; distal tarsals 3-4; metatarsals 2-5; phalanges 0.2.2.0.0 (Greer & Cogger 1985: 14).
Colour. In preservative the ground colour of the dorsum ranges from light, greyish brown to dark-brown and the venter from off-white to light-brown. The dorsal pattern is uniform in New South Wales specimens but consists of rows of dark-brown dots or dashes through the centres of the dorsal and lateral scales in the Queensland specimens. The venters are unpatterned in most specimens but consists of rows of dark spots like the dorsum in one Queensland specimen (QM J 8516) (Greer & Cogger 1985: 15).
|Comment||Limb morphology: 2 digits, 1 toe (Reduced limbs, Singhal et al. 2018, Brandley et al 2008; Cogger 2014 says it is 3, 2)|
