Pseudocerastes is a genus of vipers endemic to the Middle East and Asia. It was originally created as a monotypic genus in 1896 by Boulenger for the species Pseudocerastes persicus, [1] but three species are now recognised: the spider-tailed horned viper (P. urarachnoides); Persian horned viper (P. persicus) and Field's horned viper (P. fieldi). [2] [3] Like all other vipers, the members of this genus are venomous.
Pseudocerastes are often referred to as false-horned vipers [2] because of the horn-like structures above their eyes that are made up of numerous small scales. This is in contrast to the "true" horned viper, Cerastes cerastes , which has similar supraorbital "horns", each consisting of a single elongated scale. [4]
In 2006, Bostanchi, Anderson, Kami and Papenfuss described a new species: P. urarachnoides. It is found in the Zagros Mountains of western Iran and is described as having the most elaborate tail ornamentation of any snake yet described, save for the rattlesnakes, Crotalus and Sistrurus . [5]
P. fieldi and P. persicus were once regarded as two subspecies of the same species, but further studies on the snakes' morphology, molecular structure and toxicology determined that they are in fact separate species. [2] [6]

The Viperinae, or viperines, are a subfamily of vipers endemic to Europe, Asia and Africa. They are distinguished by their lack of the heat-sensing pit organs that characterize their sister group, the subfamily Crotalinae. Currently, 13 genera are recognized. Most are tropical and subtropical, although one species, Vipera berus, even occurs within the Arctic Circle. Like all vipers, they are venomous.
Cerastes cerastes, commonly known as the Saharan horned viper or the desert horned viper, is a venomous species of viper native to the deserts of Northern Africa and parts of the Arabian Peninsula and Levant. It is often easily recognized by the presence of a pair of supraocular "horns", although hornless individuals do occur. Three subspecies have been described.
Macrovipera lebetinus, known as the blunt-nosed viper, Lebetine viper, Levant viper, and by other common names, is a viper species found in North Africa, much of the Middle East, and as far east as Kashmir. Like all other vipers, it is venomous. Five subspecies are currently recognized, including the nominate race described here.
Field's horned viper is a species of snake in the family Viperidae. The species is native to the deserts of the Middle East. Like all other vipers, it is venomous. It was previously considered a subspecies of the Persian horned viper. The main differences between this species and the Persian horned viper are in scalation and venom composition.
Cerastes is a genus of small, venomous vipers found in the deserts and semi-deserts of northern North Africa eastward through Arabia and Iran. Three species are currently recognized by ITIS, and an additional recently described species is recognized by the Reptile Database. Common names for members the genus include horned vipers, North African desert vipers, and cerastes vipers.
Montatheris is a monotypic genus created for the viper species, Montatheris hindii, which also known by the common names Kenya mountain viper, Kenya montane viper, montane viper, and Hind's viper. Like all other vipers, M. Hindii is venomous. This is a small terrestrial species endemic to Kenya. There are no subspecies which are currently recognized as being valid.
The many-horned adder is a viper species. It is found in certain rocky desert areas, mostly along the Atlantic coast of southern Africa, in western South Africa and southwestern Namibia. It has characteristic tufts of "horns" above each eye. Like all other vipers, it is venomous. No subspecies are currently recognized.
Cerastes gasperettii, commonly known as the Arabian horned viper, is a venomous viper species found especially in the Arabian Peninsula and north to Israel, Iraq, and Iran. It is very similar in appearance to C. cerastes, but the geographic ranges of these two species do not overlap. No subspecies of C. gasperettii are recognized.
Cerastes vipera, common names Sahara sand viper and Avicenna viper, is a viper species endemic to the deserts of North Africa and the Sinai Peninsula. No subspecies are currently recognized. Like all other vipers, it is venomous.
The Mount Bulgar viper, also called the Bulgardagh viper is a viper species endemic to the mountains of southern Turkey. Like all other vipers, it is venomous. No subspecies are currently recognized.
Vipera latastei, known as Lataste's viper, the snub-nosed viper, and the snub-nosed adder, is a species of venomous snake in the subfamily Viperinae of the family Viperidae. The species is endemic to the Iberian Peninsula and northwestern Maghreb. Three extant subspecies and one extinct subspecies are currently recognized, including the nominate subspecies described here.
Montivipera latifii, known as Latifi's viper, the Iranian valley viper, or the Lar Valley viper, is a species of venomous snake in the subfamily Viperinae of the family Viperidae. The species is endemic to Iran. There are no subspecies that are recognized as being valid.
Montivipera raddei or Armenian viper is a species of viper, a venomous snake in the subfamily Viperinae of the family Viperidae. The species is endemic to Armenia, Azerbaijan, Iran, Turkey, and possibly also Iraq. Two subspecies are recognized.
Vipera renardi is a species of viper, a venomous snake in the family Viperidae. The species is endemic to Asia and Eastern Europe. Five subspecies are recognized.
Montivipera xanthina, known as the rock viper, coastal viper, Ottoman viper, and by other common names, is a viper species found in northeastern Greece and Turkey, as well as certain islands in the Aegean Sea. Like all other vipers, it is venomous. No subspecies are currently recognized.

The Persian horned viper, known as the Persian horned viper, false horned viper, and by other common names, is a species of vipers endemic to the Middle East and Asia. Like all other vipers, it is venomous.
Caudal luring is a form of aggressive mimicry characterized by the waving or wriggling of the predator's tail to attract prey. This movement attracts small animals who mistake the tail for a small worm or other small animal. When the animal approaches to prey on the worm-like tail, the predator will strike. This behavior has been recorded in snakes, sharks, and eels.
The spider-tailed horned viper is a species of viper, a venomous snake, in the family Viperidae and genus Pseudocerastes. The genus is commonly known as "false-horned vipers".
