|Types||Holotype: WAM R46197|
Holotype: WAM R74947 [talpina]
|Diagnosis||Diagnosis: Moderately large and stout Lerista with digits 0 + 2, forelimb groove, eyelid immovable (i.e. large transparent disc surrounded by a series of granules), dark upper lateral stripe, and wide vertebral stripe. Distinguishable from L. C. connivens by immovable (rather than movable) eyelid, more numerous nuchals and subdigital lamellae, slightly longer hindleg, and occurrence of individuals with frontoparietals and interparietal free.|
Distinguishable from L. nichollsi by greater size, two loreals (rather than one), and wider, more ragged-edged vertebral stripe. (Storr 1976)
Description: Snout-vent length (mm): 67.5-69. Length of appendages etc. (% SVL): hindleg 16-17; snout to forelimb groove 21-22.
Nasals forming a short to moderately long median suture. Prefrontals widely separated. In holotype frontoparietals narrowly separated, much smaller than interparietal; in paratype frontoparietals and interparietal fused (as in L. c. connivens and L. nichollsi). Nuchals 2-3. Supraoculars 3, first two contacting frontal. Supraciliaries 1 + 2 or 4. Upper labials 6. Upper secondary temporal much the largest, lower secondary much the smallest (when not fused to last labial). Midbody scale rows 20-22. Lamellae under longer toe 12.
Head, vertebral stripe and tail greyish brown; vertebral stripe wider than whitish laterodorsal strip of ground colour and enclosing four series of dark brown spots. Dark brown upper lateral stripe from nasal or lores back through orbit to tail. Upper labials barred with dark brown. Lower surface whitish except for grey dots on tail.(Storr 1976)
