摘要Based on extensive field work in the northern Zagros Mountains,a new subspecies of Darevskia raddei (Boettger,1892) from the west Azerbaijan Province,northwestern Iran is described.The new subspecies is distinguishable from all the other three subspecies of D.raddei based on the combination of several distinguishing characters,such as dorsal body with 50-55 oval to round,smooth,or very weakly keeled,scales,25-31 scales across the gular region,18-20 femoral pores on each side of body (reaching the knee),29-31 tuberculate lamellae under the fourth toe,11-12 supraciliaries,9-11 collars and a specific color pattern.The new subspecies meets all the morphological characters described by Eiselt et al.(1993) for an undefined and intermediate form between D.raddei raddei in the east of and D.r.vanensis in the west of the distribution range of the species.
