Pseudocerastes is a genus of vipers endemic to the Middle East and Asia.

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.

[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.
