Cryptoblepharus metallicus — HORNER 2007 
DistributionAustralia (from inland south-eastern Queensland, through eastern and northern Queensland, the northern half of the Northern Territory to the Kimberley region of Western Australia)

Type locality: most likely on the bank of the Victoria River, near the present-day town of Timber Creek, Northern Territory (see comment).  
Reproductionoviparous 
TypesLectotype: BMNH 57.10.24.38 
CommentDiagnosis. A large (45–50 mm SVL), short-legged, shallow-headed, arboreal Cryptoblepharus, distinguished from Australian congeners by combination of modal values of six supraciliary scales, 24 mid-body scale rows and 48 paravertebral scales; mean values of hindlimb length 41.4% of snout-vent length, head depth 41.7% of head length, tail length 144.2% of snout-vent length; smooth subdigital lamellae; rounded, usually callused plantar scales; greyish, longitudinally aligned body pattern and being arboreal.

Sympatry. C. ruber, C. cygnatus, C. juno, C. adamsi, C. exochus, C. l. horneri, C. l. litoralis, C. mertensi, C. pannosus, C. pulcher, C. tytthos, C. virgatus and C. zoticus.

Boulenger diagnosed the taxon as having “22 or 24 scales around the body. Four anterior labials. Yellowish or greenish above, strongly metallic, with small dark brown spots forming a more or less irregular band on each side”. No type locality was given, though the general area can be determined from the expedition’s journal (Gregory and Gregory 1884). Storr (1976) synonymised A. b. metallicus
with C. plagiocephalus.
