Common names: desert viper,[3][4] Libyan desert blunt-nosed viper,[5] more.

Macrovipera deserti is a venomous viper species endemic to North Africa.[1] No subspecies are currently recognized.[6]

Description

It grows to a total length (body + tail) of 1.6 m (5.2 ft).[3] Others say 1.3 m (4.3 ft).[4]

Common names

Desert viper,[3][4] Libyan desert blunt-nosed viper,[5] desert adder,[7] Sahara adder, Sahara viper.[8]

Geographic range

It is found in North Africa in Libya, Tunisia, and possibly in Algeria.

The type locality given in the original description is "Duriat, South Tunisia".[1] Mallow et al. (2003) mention that it does occur in the southern foothills of the Atlas Mountains in Algeria.[4]

Conservation status

This species is classified as Near Threatened (NT) according to the IUCN Red List of Threatened Species (v3.1, 2001).[9] It is classified as such because its extent of occurrence is probably not much greater than 20,000 km² (7,722 sq mi) and its population is likely declining due to over-harvesting and persecution, therefore making the species close to qualifying for Vulnerable. The population trend is down. Year assessed: 2005.[10]

Habitat

Occurs in rocky, mountainous areas that are semiarid, but well-vegetated.[3]

Reproduction

This species lays eggs (oviparous).[3]

Venom

Little is known about its venom. Antivenoms meant for M. lebetina and Daboia russelii show the strongest cross-reactivity with this venom.[4]

Taxonomy

Based on molecular evidence, Lenk et al. (2001)[11] suggested that this species, along with M. mauritanica, should rather be included in the genus Daboia.
