Material examined. Seven females, 1 male, and 1 deutonymph collected from upper soil surface under pussy willow trees, Salix aegyptiaca (L.) (Salicacae), IRAN: Hamedan Province, vicinity of Maryanaj City, Heydareh village (34° 48'27"N, 48° 28'0.85"E, 1873 m a.s.l.), 28 October 2010, coll. M. Khanjani. Deposited—CALBS.

Comparative material. Types of A. daneshvari deposited at CPPDRII, lent from Dr. M. Khosrowshahi; types of P. salicicola deposited at Entomology Museum, College of Agriculture, Department of Plant Protection, Abu- Ghraib, Baghdad, Iraq.

Remarks. The Iranian specimens exhibit most of the characters of P. salicicola Al-Gboory, 1987 . However, in the original description the rostrum extends to the base of genu I, but the rostrum of the Iranian specimens extends to the middle of tibia I; in the original description the area between 3a–4a and ventral plate is smooth whereas in the Iranian specimens the area between 3a–4a has transverse striations.
