This is the first case of host record for parasitoid wasps of the genus Diglyphus Walker (Hymenoptera, Eulophidae) from the Anthomyiidae (Diptera) family. This result is based on specimens of D. anadolucus Doğanlar, 1982 which reared from parasitized larval specimen of Pegomya terebrans (Rondani) as a leaf miner of cotton thistle, Onopordum acanthium L. (Asteraceae). Diglyphus anadolucus is reported from Iran for the first time. Some biological notes and morphological characteristics of D. anadolucus along with related photographs are given. An updated checklist of the twelve known Diglyphus species in Iran togther with their host associations is also provided.

Through a survey conducted in West Azarbaijan province, northwestern Iran in 2022, infested fruits of Elaeagnus angustifolia L. (Elaeagnaceae) were collected. Anarsia eleagnella Kuznetsov, 1957 (Lepidoptera: Gelechiidae) was obtained from laboratory rearing. A parasitic wasp was collected in the rearing container that was identified under Hyssopus geniculatus (Hartig, 1838) (Hymenoptera: Eulophidae). This parasitoid is a primary ectoparasitoid and a new record of H. geniculatus on A. eleagnella. Also, the association of H. geniculatus with E. angustifolia and the family Elaeagnaceae is new. Notes on the diagnostic characters of H. geniculatus are provided and illustrations of A. eleagnella and H. geniculatus are presented. The feeding behaviour of A. eleagnella larvae is preliminarily studied. Finally, the colour variations of the collected H. geniculatus specimens compared to the published literature are discussed.

Baryscapus evonymellae (Bouché, 1834) (Hymenoptera, Eulophidae) was rediscovered on Leucoma wiltshirei Collenette, 1938 (Lepidoptera, Erebidae) attacked by different parasitoids. This species had already been reported under different names; therefore, its inaccurate identifications were corrected. It was reared as a larval and pupal hyperparasitoid of two important primary parasitoids of L. wiltshirei including Brachymeria tibialis Steffan, 1958 (Hymenoptera, Chalcididae), and Dolichogenidea persica Abdoli, Mohammadi, Sedaratian-Jahromi & Farahani, 2023 (Hymenoptera, Braconidae). The last parasitoid-hyperparasitoid association is new. Its morphological characters were illustrated and its biological data and main characteristics were discussed.

Species of the genus Necremnus Thomson, 1878 (Hymenoptera: Eulophidae) in Iran are reviewed based on published data and the newly collected specimens in West Azarbaijan province. The genus in Iran is represented by only two species N. leucarthros (Nees, 1834) and N. tidius (Walker, 1839). Hereby, two additional species N. artynes (Walker, 1839) and N. cosmopterix Ribes & Bernardo, 2015 are also identified as new records for the fauna of Iran. Necremnus tidius (Walker, 1839) was also found in Northwestern Iran as a new local distributional record. An illustrated key for identifying the known Necremnus species from Iran and a short description of the newly recorded species are provided. The distribution map of the Iranian species is also presented.

Through a survey that was conducted in Basrah Province, Southern Iraq in 2021, specimens were collected from alfalfa fields (Medicago sativa L.) using a sweep net. These specimens were identified as Neotrichoporoides Girault, 1913 (Hymenoptera: Chalcidoidea, Eulophidae), which is a new report of the genus in Iraq. Three species were collected and identified, i.e. Neotrichoporoides basiflavus Li & Li, 2021; N. cavigena Graham, 1987; and N. viridimaculatus (Fullaway, 1955). An illustrated key for identifying Neotrichoporoides species in Iraq and notes on diagnostic characters of the newly recorded species along with illustrations are provided. The distribution map of the Iraqi species is presented. Furthermore, a preliminary checklist of recorded species of Eulophidae from Iraq is provided.
