Species of the subfamily Diplazontinae (Hym.: Ichneumonidae) were studied in West Azarbaijan province (Northwest of Iran). The specimens were collected using Malaise traps, during 2019–2020. Five species belonging to three genera were collected and identified. One species, Homotropus riedeli Johansson, 2020 was a new record for Iran as well as Asia. The distribution range of this species extends from Sweden to the north-west of Iran. A checklist is being compiled for 27 known Iranian species of this subfamily. In addition, a distribution map based on the recorded areas for each species within the Iranian provinces has been provided. We proposed a new direction for future biodiversity inventories of this subfamily in Iran.

The order Hymenoptera comprises an important group of insects, with ecological and economic importance, and serving as ecological indicators. Investigating the diversity and distribution of fauna is considered a prerequisite for biodiversity conservation. In this research, the hymenopteran fauna in mangrove forests on the southern coast of Iran were studied during 2021–2022. The collection was made by sweeping net and light trap. The survey revealed the presence of ten species and nine genera belonging to six families. Of which, two species, Ampulex assimilis Kohl, 1893 (Hym.: Ampulicidae) and Paridris leda Kozlov & Kononova, 1985 (Hym.: Scelionidae) are recorded for the first time for the Iranian fauna. Diagnostic characters of the new records and geographical distribution of all species are provided.

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.

The species of the genus Dusona Cameron, 1901 (Hymenoptera: Ichneumonidae: Campopleginae) are studied in four provinces of Iran (Mazandaran, Guilan, Alborz and Fars). Specimens were collected using Malaise traps during 2010–2012. Eight species of Dusona were collected and identified, among them three species, D. libertatis (Teunissen, 1947), D. limnobia (Thomson, 1887), and D. disclusa (Förster, 1868) represent new records for the fauna of Iran. Morphological characteristics of the newly recorded species are illustrated. Additionally, an updated checklist of Dusona species known from Iran is provided, along with zoogeographical distribution maps for all species collected in this study.

The data on biology and taxonomy of the new subspecies Bracon pallicarpus dorytomovorus Samartsev & Dokuchaev ssp. nov. are given. It was shown that in the Northern Okhotsk region, the wasps of the new subspecies are solitary univoltine parasitoids of the Dorytomus cinereus Hochhuth, 1851 (Coleoptera, Curculionidae) larvae which feed on the central axis of the catkins of the willow Salix rorida Lakschevitz (Salicaceae). Having consumed the weevil larva, the parasitoid forms a cocoon inside the host's tunnel and overwinters as a pupa inside the fallen catkin. Bracon pallicarpus dorytomovorus ssp. nov. adults emerge the next year in the second half of May. The status of the specimens of the type series of B. pallicarpus pallicarpus Thomson, 1892 was specified and its differences from 30 closely related species are presented. Bracon schmiedeknechti Fahringer, 1927 was synonymised with B. pallicarpus pallicarpus (syn. nov.).

Chalcidoidea is a hyperdiverse superfamily of mostly small, parasitoid wasps of which 14 families and at least 422 species have been recorded from Greece. In the present study, additional distributional data from Greece is provided for Brachymeria rugulosa (Forster, 1859) and Brachymeria tibialis (Walker, 1834). Furthermore, Brachymeria podagrica (Fabricius, 1787) and Monodontomerus obscurus Westwood, 1833 are recorded for the first time from Greece. As well, a new host gall species for B. rugulosa is noted and the presence of Brachymeria inermis (Fonscolombe, 1840) is briefly discussed. Finally, a checklist for the genera Brachymeria (Hymenoptera, Chalcididae) and Monodontomerus (Hymenoptera, Torymidae) is compiled.

In this study, the specimens of the genus Cinetus Jurine, 1807 (Hymenoptera: Diapriidae) were collected using the Malaise traps during 2010-2019 in Northern Iran. The genus Cinetus and five related species are recorded from Iran for the first time: Cinetus angustatus Kieffer, 1910, C. ditomus (Kieffer, 1910), C. fuliginosus Curtis, 1831, C. iridipennis Lepeletier and Serville, 1825 and C. simulans Nixon, 1957.

The collected and distribution data, diagnoses, illustrations of the new records, and host information are provided.

The fall webworm, Hyphantria cunea (Drury, 1773) (Lepidoptera, Erebidae), is one of the most important pests of forest trees in northern Iran. In order to identify the native parasitoids of this pest a survey was conducted in Guilan province, in 2019. The larvae and pupae of the fall webworm suspected being parasitized, were collected from different host trees and wood piles, and reared under laboratory conditions until the parasitoids emerged. This pest was found parasitized with five species of Hymenoptera, Brachymeria lasus (Walker, 1841) (Chalcididae), Chouioia cunea Yang, 1989 (Eulophidae), Psychophagus omnivorus (Walker, 1835) (Pteromalidae), Pimpla rufipes Brulle, 1846, Virgichneumon dumeticola (Gravenhorst, 1829) (Ichneumonidae), and four species of Diptera, Compsilura concinnata (Meigen, 1824), Exorista larvarum (Linnaeus, 1758), Pales sp. (Tachinidae), and Megaselia scalaris (Loew, 1866) (Phoridae). Among them six species (e.g., P. rufipes, V. dumeticola, B. lasus, E. larvarum, C. concinnata and Pales sp.) are newly reported as the parasitoids of H. cunea from Iran.

During the collection of Ichneumonidae from West Azarbaijan province in the northwest of Iran in 2019, we collected a specimen belonging to the subfamily Tersilochinae and identified it as Aneuclis pumilus (Holmgren). This is a new record of this species for the Iranian fauna. A checklist of all known Iranian species of the subfamily is provided.

The occurrence of Pauesia silana Tremblay, as an aphid parasitoid (Hym., Braconidae, Aphidiinae) in Tunisia is documented. The parasitoid was found in association with the Aleppo pine aphid, Cinara palaestinensis Hille Ris Lambers, infesting Pinus halepensis. Specimens were collected by the rearing of the mummified aphids from the colonies infested the pine trees in the Arboretum of the Institut Supérieur Agronomique Chott Mériem (ISA CM - Tunisia) during March–April 2021. A brief diagnosis is provided for the recorded parasitoid. This is the first record of a Pauesia species in Tunisia (out of the purposeful introduction of Pauesia antennata Mukerji). Two secondary parasitoids including Asaphes vulgaris Walker and Pachyneuron aphidis (Bouché) (Hym., Chalcidoidea, Pteromalidae) have also emerged from the mummified aphids. The known Cinara aphids and their associated parasitoids in the North African country are reviewed. Both Aleppo pine aphid and the newly detected parasitoid might be considered exotic species in North Africa, sourced from a recent accidental introduction inside the Mediterranean area, or a horizontal expansion across the North African countries.

Chalcidoidea play an important role in the biological control of many agricultural pests. The present study determines and compares the diversities of this superfamily in four ecosystems in the Lake Urmia basin. It is the largest hypersaline lake in the world with a large basin of different ecological conditions in northwest Iran. These stations were: Khajeh (K) and Tasuj (T) in Lake Urmia Basin (LUBin) and Khoda-Afarin (KA) and Tikme-Dash (TD) out of their (LUBout). Four months of Malaise trapping in these habitats resulted in a total of 512 specimens from 11 families of Chalcidoidea, including 6, 9, 10 and 10 families in K, KA, T and TD, respectively. Maximum abundance was observed in the T station with 192 and the minimum was in the K station with 38. However, the families, Encyrtidae and Chalcididae have maximum abundance in T and KA, respectively. The maximum activity of chalcidoid wasps was observed during June-August. The majority of the species were belonging to the family Mymaridae (25%), in LUBout habitats peaked at 47 specimens in TD during the sampling period, while the corresponding LUBin habitats peaked at 40 specimens in T. The two LUBout habitats had greater community similarity (60%) than found between in and LUBout habitats (42%) and diversity of chalcidoid wasps in LUBout was found much more than LUBin. Biodiversity studies showed that the KA station has the greatest values of diversity, evenness, and richness of Chalcidoidea. This station is located outside of Lake Urmia basin with the warmest and most humid climate and forest ecosystem on the margins of the Aras River.

Stenomesius japonicus (Ashmead, 1904) (Hymenoptera: Eulophidae) was collected for the first time from larvae of the tomato leaf-miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) infesting Lycopersicon esculentum Mill. in Syria. Diagnostic morphological characters, biology and distribution of the newly recorded species are provided. Its role in the biological or integrated control of T. absoluta remains to be evaluated. A list of all eulophid wasps recorded from Syria is also provided.

A study was conducted to determine the braconinae (Hym., Braconidae) parasitoid wasps, associated with Asteraceae in the northwest of Iran during 2013-2015. Ten species were reared from flower-heads of Asteraceae: Bracon bipartitus Wesmael, 1838; B. leptus Marshall, 1897; B. luteator Spinola, 1808; B. mariae Dalla Torre, 1898; B. pectoralis Wesmael, 1838; B. subrugosus Szépligeti, 1901; B. talyshicus Tobias, 1976; B. trucidator Marshall, 1888; B. tschitscherini Kokujev, 1904 and B. urinator (Fabricius, 1798), of which one species (i.e., B. talyshicus) is recorded for the first time from Iran. We also reared some non-frugivorous Tephritidae feeding on the collected flower-heads that can be possible host of these braconids. General distribution and biological associations for all species that have been collected in this study are compiled.

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.

We report the discovery of the parasitic wasp, Anomalon cruentatm (Hymenoptera: Ichneumonidae, Anomaloninae) for Syria. It is the first record of A. cruentatm in Syria. It was collected in a greenhouse in Lattakia province. Its description, distribution and photographs are provided.

We present two new distribution records which add information about the presence of Pseudotorymus ispirlii Doğanlar and P. pulchellus Masi (Hymenoptera: Chalcidoidea, Torymidae) in the northwest of Iran. Based on present records, both species were found for second times after type localities.
