|Distribution||Australia (NE Queensland, restricted to Thornton Peak and the uplands of the Carbine Tableland, e.g., Mt Lewis, Mt Spurgeon)|
Type locality: Thornton Pk, via Daintree, NEQ (16°10'S, 145°23'E).
|Types||Holotype: QM J43911|
|Diagnosis||Diagnosis: A large Lampropholis with dark flanks and prominent spotting on the posterior ventral surfaces, a row of dark edged pale spots on underside of tail. This species is reliably distinguished from its closest congener (L. bellendenkerensis sp. nov. ) by 14 nucleotide differences in the mitochondrial gene NADH dehydrogenase 4 that result in nine amino acid differences between the species (Table A2 in Singhal et al. 2018).|
Measurements and scale counts of holotype QM J43911: SVL 45.3 mm; AG 22.9; L1 12.0 mm; L2 15.9 mm; HL 8.41 mm; HW 6.0 mm; midbody scale rows 28; paravertebral scales 53; lamellae beneath fourth toe 26; supralabials 7; infralabials 6; supraciliaries 7.
Description: SVL 36.6–51.45 mm (n = 17, mean = 44.35); AG % SVL 46–54% SVL (n = 17, mean = 50%); L1 26–32% (n = 17, mean = 29%); L2 34–43% SVL (n = 17, mean = 38%); HW 69– 79% HL (n = 17, mean = 73%). Body: Robust. Head and body continuous with almost no narrowing at neck. Snout rounded in profile. Limbs well-developed, pentadactyl, meeting or narrowly separated when adpressed. Scalation: Dorsal smooth (or with three to four faint striations) with a broadly curved posterior edge; nasals widely spaced; rostral and frontonasal in broad contact; prefrontals moderately to widely separated; frontal contacting frontonasal, prefrontals, first two supraoculars and frontoparietal; supraoculars four, second largest; supraciliaries seven, first usually largest but sometimes subequal to third or fourth; lower eyelid movable with small palpebral disc, less than half the size of lower eyelid; ear opening round to vertically elliptic, subequal to palpebral disc; frontoparietals fused, interparietal free; primary temporal single, secondary temporals two (upper largest and overlapping lower); loreals two, subequal or second largest; preoculars two, lower largest; presuboculars two, upper largest; supralabials seven with fifth below eye (eight in QM J55833, with sixth below eye), and last overlapping lower secondary temporal and postsupralabials; postsupralabial divided; infralabials six (seven in QM J55833 and J56464) two in contact with postmental; midbody scale rows 26–28 (n = 23, mode = 26); paravertebral scales (to the level of the posterior margin of the hindlimbs) 49–54 (n = 21, mode = 54); fourth toe longest, subdigital lamellae 21–26 (n = 21, mode = 23) with a single row of scales on the dorsal surface; outer preanal scales overlap inner preanals; three pairs of enlarged chin shields, first pair in contact, second pair separated by a single scale row, third pair separated by three scale rows.
Comparison with similar species: Lampropholis robertsi and L. bellendenkerensis sp. nov. cannot be separated using morphological characters. They are distinguished genetically by 13 nucleotide differences in the mitochondrial gene NADH dehydrogenase 4 that result in nine amino acid differences between the two species (Table A2).
|Comment||Habitat: Occurs in upland rainforest and heath (all records come from above approximately 900 m elevation). Most often seen in warmer, sunlit areas such as in canopy gaps or rocky areas.|
|Etymology||Named after Dr. J. Austin Roberts (1883-1948), a South African zoologist who in his day was the most prominent ornithologist in southern Africa.|
