A survey was carried out on the hyperparasitoids of the poplar spiral gall aphid, Pemphigus spyrothecae Passerini, 1860 in Ardabil province from 2012 to 2013. Two pteromalid species, including Pachyneuron solitarium (Hartig, 1838) and Asaphes suspensus (Nees, 1834) were reared from the mummified aphids. Both species are hyperparasitoid of P. spyrothecae via Monoctonia vesicarii Tremblay, 1991 (Hymenoptera: Braconidae, Aphidiinae). Pachyneuron solitarium is newly recorded from Iran.
