The Schokari sand racer or Forskal sand snake (Psammophis schokari) is a species of psammophiidsnake found in parts of Asia and Africa.[1][2]Psammophis aegyptius has at times been considered a subspecies of Psammophis schokari but is presently considered a full species.[3] Many people refer to snakes in the genus Psammophis as colubrids, but this is now known to be incorrect — they were once classified in the Colubridae, but our more sophisticated understanding of the relationships among the groups of snakes has led herpetologists to reclassify Psammophis and its relatives into Lamprophiidae, a family more closely related to Elapidae than to Colubridae.[4]
