REMARKS. Phrynocephalus persicus was separated from P. helioscopus on the basis of the analysis of allozyme variation (Mezhzherin & Golubev 1989). There is an immense chaos regarding the form horvathi Méhely which was originally described as a subspecies of P. helioscopus from the foothills of Ararat, Armenia (Méhely 1894) and which is endemic to E Anatolia, S Armenia, Azerbaijan and NW Iran. In Iran it is restricted to the vicinity and north of the Lake Urmia (Melnikov et al. 2008). Some authors treat this form as it was described — a subspecies of P. helioscopus (Rastegar-Pouyani et al. 2008; Tosunoğlu et al. 2011), some as a subspecies of P. persicus (Barabanov & Ananjeva 2007; Arakelyan et al. 2011; Solovyeva et al. 2011; Milto & Barabanov 2012) and yet others as a full species (Çiçek et al. 2011). According to Anderson (1999), P. horvathi appears to be a younger synonym of P. persicus. This assumption is in accordance with the results of mtDNA analyses of P. helioscopuspersicus complex by Solovyeva et al. (2011) which proved horvathi to be an inner lineage of P. persicus. The name horvathi was stabilized by Melnikov et al. (2013), who designated neotype (see remarks by P. persicus below).
