DistributionOman Mts. (Oman, United Arab Emirates)

Type locality: Trucial States, Wadi Shawkah, 25°06’ N, 50°03' E.  
TypesHolotype: BMNH 1971.1291, female 
DiagnosisDiagnosis: A small species of Lacerta assignable to Part II of the genus (Arnold 1973) and differentiated from all other species by possessing a double series of carinate and bluntly spinose lamellae on the undersides of the digits. Other characters, which in combination define L. cyanura, are very slender limbs and tail, very depressed habitus, a series of strongly expanded plates under lower forelimb, large scales on the tibia, very strongly keeled caudal scales, hemipenis with well-developed armature (see Arnold 1972: 120), retracted lobes flattened and complexly folded, and micro-ornamentation of crown-shaped tubercles, and bright blue tail. L. jayakari, which is sympatric with L. cyanura, is much larger, has higher meristic counts and tubercular subdigital lamellae and a hemipenial micro-ornamentation of recurved spines.
L. cappadocica of Turkey, North Iraq and N.W. Iran has carinate toes but there is only one series of subdigital lamellae and the lower eyelid has a 'window' of transparent, black-edged scales (from Arnold 1972: 116 ff). 
CommentJuveniles have whitish-yellowish and dark longitudinal stripes and bluish tails while adults have rather uniform brownish color with blue tails and bellies.

Phylogenetics: O. cyanura is clearly split into northern and southern populations (Mendes et al. 2018).

Distribution: See map in Burriel-Carranza et al. 2019 for map in UAE.
