Material examined. 1 female and 1 deutonymph collected from plum leaf, Prunus domestica L. ( Rosaceae ), 1 female collected from vine leaf, Vitis vinifera L. ( Vitaceae ), 3 females collected from hawthorn leaf, Crataegus monogyna Jacq. (Rosaceae) , 7 females and 2 larvae collected from quince leaf, Cydonia oblonga Mill. (Rosaceae) , IRAN: Hamedan Province, Hamedan, 34º 45ʹ N, 48º 31ʹ E, 1991 m a. s. l, 8 September 2010, coll. M. Khanjani; 12 females collected from hawthorn leaf, C. monogyna Jacq. (Rosaceae) , IRAN: Ardabil Province, Heyran, 38º 26ʹ N, 48º 35ʹ E, 1475 m a. s. l, 23 September 2008, coll. B. Asali Fayaz. Deposited in CALBS.

Remarks. The Iranian specimens exhibit most features of the original description except that in the original description the rostral shield has medial lobes that are irregularly notched (smooth in re-description), the ratio d1 / d1–d1 is 0.19 (0.29–0.30 in redescription) and the ratio d3/d3–e3 is 0.47 (0.34–0.36 in re-description). These differences seem minor and therefore our specimens are deemed to be conspecific.
