Distribution: A record from Lebanon (Harding and Welch 1980) must be disregarded.
Considered as subspecies of P. persicus by Leviton et al. and other authors (Golay et al. 1993 etc.).
Probably the main external morphological difference between P. persicus and P. fieldi is that the scale rows of P. persicus are all strongly keeled, whereas in P. fieldi several lateral rows are nearly smooth and the outer rows are entirely without keels. Pseudocerastes fieldi also has a significantly shorter tail (after BOSTANCHI et al. 2006).
Etymology: named after Henry Field who collected the type on May 9, 1928.
