Three species of inquiline cynipids and 11 parasitoids associated with galls of the asexual form of Andricus synophri Pujade-Villar, Tavakoli & Melika, 2015 are cited for the first time. The inquiline species Synergus tavakolii Pujade-Villar sp. nov. (Hymenoptera: Cynipidae, Synergini) is described. Bootanomyia onuri Doganlar, 2011 (Hymenoptera: Chalcidoidea, Megastigmidae) is reported for the first time in Iran, and Baryscapus anasillus Graham, 1991 (Hymenoptera: Chalcidoidea, Eulophidae) for the first time in Asia. A key for Synergus Hartig, 1840 species belonging to Section II of Mayr without pronotal carina is provided. The characters to differentiate Sycophila biguttata (Swederus, 1795) and S. variegata (Curtis, 1831) are discussed.
