Description "A medium to large, slender snake reaching up to 1,900 mm. Tail long, tail / total length = 0.27-0.3. Eyes notably large and bulging, nostril in a divided nasal; loreal elongate, longer than nasals; 9 supralabials, usually fifth and sixth enter the eye, 10 infralabials; 170-198 ventrals, 158-178 paired subcaudals, dorsals smooth, 17 scale rows around mid-body, anal divided. Two Egyptian examples were between 900-1200 mm long. Dorsal side of head and neck plain light olive-gray. Two narrow black stripes extended on each side of the head from the snout through the eyes, merging on the nape, forming a single broad black median stripe that extends posteriorly to the tail tip. This median stripe is bordered on each side by a narrow yellowish stripe, followed by a broad gray band on each flank. Venter white with scattered black spots, throat and labials white." (2)
Habitat "Lightly vegetated hills in dry Acacia scrubland."(2)
Behaviour "Diurnal. The Gebel Elba examples were found in the late afternoon, at an elevation of between 200-500 meters. One of the animals was encountered while it was pursuing a Ptyodactylus ragazzii across a large boulder, in a small, fairly well-vegetated gully."(2)
Comment trivirgatus may be a valid species (Largen & Rasmussen 1993).

Distribution: CORKILL & COCHRANE 1966 list this species from the Arabian peninsula, probably in error.(1)
