Abstract

During a survey conducted in West Azarbaijan Province, northwestern Iran, some grasses (Poaceae) were collected from 2021 to 2023. Plant tissue samples of Bromus tectorum (L.) Nevski, Dactylis glomerata L., Lolium perenne L., Phalaris minor Retzand, Phragmatis australis (Cav.) Trin. ex Steud. were transferred to the Entomology Laboratory at Urmia University, where chalcidoid wasps were reared. Eleven species of Eulophidae (Hymenoptera: Chalcidoidea) across five genera and three subfamilies were identified, i.e. Pediobius epigonus (Walker, 1839) and P. metallicus (Nees, 1834) (Entedoninae); Cirrospilus ingenuus Gahan, 1932; Diglyphus isaea (Walker, 1838) and D. sabulosus Erdös, 1951 (Eulophinae); Aprostocetus apiculatus Graham, 1987; A. forsteri (Walker, 1847); A.phragmiticola Graham, 1987; Aprostocetus sp.; Baryscapus endemus (Walker, 1839), and B.turionum (Hatrig, 1838) (Tetrastichinae). Notably, two species, A.apiculatus and A.phragmiticola, are new records for the Iranian fauna. All the species except for D. isaea and D. sabulosus are new distributional records. The association of B. tectorum, D. glomerata, L. perenne, P. minor and P. australis with corresponding eulophids are new. All potential hosts associated with each species have been thoroughly discussed. Furthermore, notes on diagnostic characters of the newly recorded species along with illustrations are provided
