"The Toad-headed agama, Phrynocephalus mystaceus Pallas 1776, was described in 1999 from eastern Khorasan by Anderson. Seven specimen of The Toad-headed agama were collected in Khar Turan National Park during fieldwork from June 2008 to June 2009. The new locality of the species is situated about 900 km west of the type locality. This record indicates a wider distribution of Phrynocephalus mystaceus on the Iranian plateau than previously thought. Information on morphological characters and habitat is presented."
