Diagnosis 
CommentSynonymy: Leptodira tripolitana WERNER 1909 has been removed from the synonymy of T. (dhara) obtusus and is now considered as valid species, Telescopus tripolitanus.

Distribution: See maps in Schleich et al. 1996: 526, Geniez 2016: 204. Reports from Libya westwards (Morocco, Algeria (Joger in Böhme et al.), Tunisia [gabesi = gabesiensis], Mali?, N Nigeria?, Sierra Leone) belong probably to T. tripolitanus (as T. guidimakaensis; see Geniez et al. 2004). Spawls et al. 2018 apparently considered this species as a synonym of T. dhara.

Type species: Coluber obtusus REUSS 1834: 137 is the type species of the genus Telescopus WAGLER 1830.

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

Venomous, but usually not dangerous to humans.
