The following is a description of the only known Egyptian specimen: Small worm-like snake, total length 97 mm; tail 6 mm long, much longer than wide, terminating with a small conical spine-like scale. Head slightly broader than body. Body cylindrical, thin, 1.5 mm wide, total length / body diameter = 65 (48-67); covered with smooth scales of uniform size, 14 transverse scale rows around the body, 12 around the tail, 354 dorsals between frontal and tail tip (average 321 [281-375] ), 31 subcaudals. Eyes vestigial, visible as small dark dots below large ocular scales, which reach upper lip. Snout is rounded; rostral rather broad, about half the head width, not reaching posteriorly to the interorbital line, pre-oral concavity present but rostral not beaked; nasals divided; prefrontal much larger than supraoculars. Occipitals enlarged, not divided. Posterior supralabi-als medium-sized, twice the size of the anterior supralabials, not reaching the level of the eye.

Global Distribution

provided by Bibliotheca Alexandrina LifeDesk

Southwest Arabia and northeast Africa. The specimen from Wadi Haifa indicates the possible occur­rence of the species along the southern Egyptian Nile Valley as well, however the formation of Lake Nasser might have caused the extinc­tion of the species from the region. Formerly thought to be a southwest Arabian endemic.

Schmidt and Marx (1957) indicate that the single Egyptian specimen was collected at mid-morning on loose sand near an Acacia tree on the coastal plain, north of Gebel Elba. A specimen also referred to L. nursii  from Wadi Haifa, Sudan, was collected "on the ground near the Nile".
