Atractaspis is a genus of venomous snakes in the family Atractaspidae, also known as the stiletto snakes. The genus is endemic to Africa and the Middle East. The genus contains 15 species that are recognized by ITIS. [2] Others recognize as many as 21 species. [3] [4] [5] 23 are listed here.
Common names for snakes of the genus Atractaspis include burrowing vipers, burrowing asps, mole vipers, stiletto snakes, side-stabbing snakes, side-stabbers. "Side stabbing" refers to the snakes' uncommon ability to strike with the side of their head and inject venom with one protruding fang. [1]
Species of the genus Atractaspis are found mostly in Sub-Saharan Africa, with a limited distribution in the Jordan valley in Israel, Palestine and the Arabian Peninsula. [1]
Members of the genus Atractaspis share the following characteristics. Venom fangs enormously developed; a few teeth on the palatines, none on the pterygoids; mandibles edentulous anteriorly, with 2 or 3 very small teeth in the middle of the dentary bone. Postfrontal bone absent. Head small, not distinct from neck, covered with large symmetrical shields; nostril between 2 nasals; no loreal; eye minute, with round pupil. Body cylindrical; dorsal scales smooth, without apical pits, in 17 to 37 rows; ventrals rounded. Tail short; subcaudals either single or in two rows. [6]

**) Not including the nominate subspecies.
The Atractaspididae (atractaspidids) are a family of venomous snakes found in Africa and the Middle East, commonly called mole vipers, stiletto snakes, or burrowing asps. Currently, 12 genera are recognized.
The boomslang is a highly venomous snake in the family Colubridae. The species is native to Sub-Saharan Africa.
Rhabdophis subminiatus, commonly called the red-necked keelback or red-necked keelback snake, is a species of venomous snake in the subfamily Natricinae of the family Colubridae. The species is endemic to Asia. Unusual for snakes, it is also poisonous.
Echis is a genus of vipers found in the dry regions of Africa, the Middle East, India, Sri Lanka and Pakistan. They have a characteristic threat display, rubbing sections of their body together to produce a "sizzling" warning sound. The name Echis is the Latin transliteration of the Greek word for "viper" (ἔχις). Like all vipers, they are venomous. Their common name is "saw-scaled vipers" and they include some of the species responsible for causing the most snakebite cases and deaths in the world. Twelve species are currently recognized.
Proatheris is a monotypic genus created for the viper species, Proatheris superciliaris. This is a small terrestrial species endemic to East Africa. Like all other vipers, it is venomous. No subspecies are currently recognized.
Atractaspis bibronii is a species of venomous snake in the family Atractaspididae. The species is endemic to Africa. There are no subspecies that are recognised as being valid. Its common names are the Southern stiletto snake, Bibron's stiletto snake, Side-stabbing snake; previously it was known as Bibron's burrowing asp, Bibron's mole viper, and the mole adder.
The horned adder is a viper species. It is found in the arid region of southwest Africa, in Angola, Botswana, Namibia; South Africa, and Zimbabwe. It is easily distinguished by the presence of a single, large horn-like scale over each eye. No subspecies are currently recognized. Like all other vipers, it is venomous.
Bitis inornata is a venomous viper species found only in Cape Province, South Africa. No subspecies are currently recognized.
Amblyodipsas is a genus of snakes found in Africa. Currently, 9 species are recognized. These snakes are often known as purple-glossed snakes or glossy snakes. Although rear-fanged, all species are considered harmless, but their venom has not been well studied. They should not be confused with the glossy snakes of the genus Arizona, which are found in North America.
Aparallactus is a genus of rear-fanged mildly venomous snakes in the family Atractaspididae. The genus is endemic to Africa. 11 species are recognized as being valid.
The twig snakes, also commonly known as bird snakes or vine snakes, are a genus of rear-fanged venomous snakes in the family Colubridae. The genus is native to Africa. All species in the genus have a slender and elongated profile, a long tail, a narrow head and a pointed snout. The eye of all species has a horizontal pupil, shaped like a keyhole, which gives twig snakes binocular vision. Twig snakes are greyish-brown with faint light and dark markings. When threatened, they inflate the throat to display bold black markings between the scales. Twig snake bites are potentially deadly: the venom is hemotoxic, affecting the blood clotting mechanism and causing uncontrolled bleeding and internal hemorrhaging. Bites by twig snakes have caused death in humans; famous herpetologist Robert Mertens died after being bitten by his pet savanna vine snake. However, envenomed bites are extremely rare when not handling the snake, as the fangs can't breach the skin except in a few places like the web between the thumb and fingers.
The small-scaled burrowing asp is a species of atractaspidid snake from West Africa.
Atractaspis aterrima, commonly known as the slender burrowing asp or mole viper, is a species of fossorial, venomous snake in the family Atractaspididae. The specific epithet, aterrima, meaning "blackest", is the superlative form of the Latin adjective ater, meaning "black".
Atractaspis battersbyi, also known commonly as Battersby's burrowing asp and Battersby's mole viper, is a species of venomous snake in the family Atractaspididae. The species is native to Central Africa.
Atractaspis boulengeri, also known commonly as Boulenger's mole viper, the Central African burrowing asp, and simply the mole viper, is a species of venomous snake in the subfamily Atractaspidinae of the family Lamprophiidae. The species is endemic to Africa. There are six recognized subspecies.
Atractaspis duerdeni, commonly known as the beaked burrowing asp, Duerden's burrowing asp, and Duerden's stiletto snake, is a species of venomous snake in the family Atractaspididae. The species is native to southern Africa.
Atractaspis engdahli, also known commonly as Engdahl's burrowing asp, Engdahl's burrowing viper, and the mole viper, is a species of venomous snake in the family Atractaspididae. The species is endemic to Africa.
Atractaspis scorteccii, commonly known as Scortecci's mole viper or the Somali burrowing asp, is a species of venomous snake in the family Atractaspididae.
Atractaspis engaddensis, also known as the Israeli Mole Viper or "الأسود الخبيث" or "שרף עין גדי" and "צפעון שחור" is a venomous snake found in Egypt, Palestine, Israel, Jordan, and Saudi Arabia. The specific epithet references the type locality, Ein Gedi on the western shore of the Dead Sea.
Amplorhinus multimaculatus, commonly known as the many-spotted snake or the Cape reed snake, is a species of mildly venomous snake in the family Pseudoxyrhophiidae. The species, which is native to southern Africa, is monotypic in the genus Amplorhinus.
