Common name. Not determined.

Diagnosis. Occipital tubercles and supraocular horns always absent; upper labials 12-13; lower labials 13-15; 12-14 scales surrounding the eye; 31-35 scale rows at midbody; ventrals 146-158^-,anal divided: subcaudals divided and vary from 31-36. Extremely short tail. Sexual dimorphism appear clearly: Males in comparison with females have shorter snout-vent length, longer tail, dorsal scale length dorsals at midbody, less ventrals and more caudals. Adult  snout-vent length measures 443mm; tail is 50-66 mm. Coloration: Irregular small dark dots with irregular shapes and sizes are scattered on head. Laterally dark band is accentuated by whitish upper margin extending between the eye corners of mouth. Dorsal background is sandy beige. Dorsal pattern differs within and among members of this subspecies. Middorsal blotches are represented by two dorsolateral series of smaller roundish blotches alternately positioned on left and right sides. These may form a zigzag pattern on same part of the body, oblique pairs of blotches or checkered throughout, but to a lesser degree regular discrete blotches have brown color. Ventrum is white.

Habitats and ecology. This viper is endemic to the sand dunes of Wadi ‘Araba between Ghawr as Safi in the north and ‘Aqaba in the south. It is nocturnal, and encountered hiding into rodent burrows or at the base of shrubs buried in soft sand except for the protruding nostrils and eyes. ​
