Pseudocerastes Urarachnoides

Pseudocerastes is a genus of venomous vipers endemic to the Middle East and Asia. It was originally a monotypic genus created in 1896 by Boulenger for the species Pseudocerastes persicus. Due to taxonomic revision and recent discovery, the genus may currently contain as many as three species.
Pseudocerastes persicus is often referred to as the false horned viper because of the horn-like structures above the 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. Two subspecies are currently recognized, including the nominate subspecies, Pseudocerastes persicus persicus.
