Remarks. The Iranian specimens exhibit most features of the original descriptions, except that the original description has propodosomal pores (absent in redescription), the rostral shield has two long and pointed medial lobes (medial lobes blunter and shorter in redescription), the ratio v2 / v 2–v2 1.5 (ratio 1.03–1.05 in redescription) and ratio c1/c1–c1 0.33 (0.44–0.54 in redescription).

This species is widely distributed in Iran and occurs on several host species of importance to man, especially rosaceous species.
