DiagnosisDiagnosis. - A species of Telescopus with the loreal separated from the eye. In its relatively narrow snout and elongate dark body blotches it resembles T. obtusus (Reuss), the only species recorded from Sudan, but it differs from that form in having only two labials entering the eye, in its lower ventral and subcaudal counts, fewer dorsal blotches and in the presence of dark ventral blotches. Specimens of T obtusus from Egypt and Sudan also differ from T gezirae in having the dorsal markings ill defined or absent, they also normally have 23 scale rows at rnidbody (Anderson, 1898; Loveridge, 1955). In its low ventral and subcaudal counts it resembles T. beetzii (Barbour) of southern Namibia and western Cape Province (Broadley, 1983), but is distinguished therefrom by the proportions of the head shields, having only two supralabials entering the eye, the frontal in good contact with the preoculars and divided anal. The dorsal blotches are more elongate and slightly less numerous. From T. variegatus (Reinhardt) of West Africa, the new form is distinguished by its lower ventral and subcaudal counts and different colour pattern. From T pulcher (Scortecci) and T semiannulatus A. Smith it differs in higher midbody scale count, also differing fronl the former species in its higher ventral and lower subcaudal scale counts. The subtriangular frontal shield of T gezirae appears to be unique in the genus. 
CommentKnown from only 2 specimens (Crochet et al. 2008).

Habitat: partly arboreal (Harrington et al. 2018).
