This study was performed on the collections of the National Zoological Collection of the Zoological Survey of India and described a new species in the “multidentati” Cyphoderus group from Bihar, India. This new species, Cyphoderus bihariensis sp. nov., is described with a distinguishing comparison among other species within this group. The new species is notably large compared to its counterparts in this group. This study also redescribed Cyphoderus javanus Börner, 1906 collected from various localities and habitats across India and provides additional morphological identification characters and chaetotaxy for taxonomic sufficiency. Earlier, India was home to nine Cyphoderus species from various localities across the country. Additionally, an identification key to the Indian Cyphoderus is included.

The genus Ametastegia Costa 1882 (Hymenoptera: Tenthredinidae: Allantinae) was studied in northern Iran. The specimens were collected using sweeping net and Malaise traps during March to November 2010 and 2011. Four species were collected and identified of which Ametastegia persica Khayrandish, Talebi & Blank sp. n. is described as new to science. An illustrated key for identification of Ametastegia species in Iran is provided.

The fauna of the subfamily Diplazontinae (Hymenoptera: Ichneumonidae) in the north central parts of Iran was studied during 2010-2011. A total of 933 specimens were collected in 30 localities at different altitudes using Malaise traps. Sixteen species belonging to 7 genera were identified of which twelve species indicated by asterisk, are new records for Iran: Diplazon annulatus (Gravenhorst)*, Diplazon laetatorius (Fabricius),D. pectoratorius (Gravenhorst)*, D. tibiatorius (Thunberg)*, Enizemum ornatum (Gravenhorst), Homotropus nigritarsus (Gravenhorst)*, Homotropus pictus (Gravenhorst)*, Promethes sulcator (Gravenhorst), Sussaba flavipes (Lucas)*, Sussaba pulchella (Holmgren)*, Syrphoctonus tarsatorius (Panzer)*, Syrphophilus bizonarius (Gravenhorst)*, Tymmophorus obscuripes (Holmgren)*, Woldstedtius biguttatus (Gravenhorst), Woldstedtius citropectoralis (Schmiedeknecht)* and Xestopelta gracilima (Schmiedeknekht)*. Detailed morphological characters and a key to the genera and species are provided. Flight periods and distribution in relation to altitude on two slopes of the Alborz mountains are discussed.

A survey was carried out on the genus Colotrechnus Thomson, 1878 (Hym., Pteromalidae) in North Eastern (North Khorasan) and South Eastern (Kerman) provinces of Iran. Two species including Colotrechnus subcoeruleus Thomson, 1878 and Colotrechnus viridis (Masi, 1921) were found, of which the first species is newly recorded from Iran. The new findings represent distribution of this genus along a wide area in Eastern provinces of Iran. An illustrated key to known Iranian species, as well as a brief diagnosis for each species are provided. A distribution map throughout the Palaearctic region is also generated and discussed.

An updated checklist of the scorpiofauna of Iran is presented. The checklist is based on records of scorpion species which their presence have been confirmed in Iran through field expeditions, examination of scorpion collections, literature review, and personal communications with researchers. According to the presented checklist the scorpion fauna of Iran consists of 68 valid species (41 endemic to Iran) belonging to 19 genera and four families and 6 doubtful reports (belong family Buthidae). Hemiscorpius gaillardi (Vachon, 1974) and Compsobuthus jakesi Kovařík, 2003 reported for the first time from Hormozgan province. Odontobuthus tavighiae Navidpour et al., 2013 collected for the first time from Fars province. Kraepelinia palpator (Birula, 1903) and O. tirgari Mirshamsi et al., 2013 were new record for South Khorasan province fauna. The list is dominated by members of the family Buthidae (58 species) with 85.3% of total species. The level of regional endemism exceeds 60.3%. A dichotomic identification key to the Iranian species on the basis of a DELTA database has been provided.

The tribe Orthosiini Guenée, 1837, one of the six tribes of Hadeninae subfamily is represented by 17 genera worldwide. Of those, three genera including Orthosia Ochsenheimer, 1816, Perigrapha Lederer, 1857 and Egira Duponchel, 1845 have recorded in Iran. Here, we present a Catalogue of Orthosiini of Iran including 15 species of this tribe with their provincial distribution in Iran. Identification keys for the Iranian species are provided as well. Perigrapha cilissa Püngeler, 1917 is recorded for the first time from Iran. The external and genital characteristics of the newly recorded species are given, beside the illustrations of the adults and their genitalia.

In July 2022 several grasshoppers of the genus Miramella Dovnar-Zapolskij, 1932 were encountered on two localities in Montenegro. Voucher specimens were sampled. It became clear that these did not belong to the species Miramella albanica Mistshenko, 1952. They also deviated in morphology and habitat from Miramella irena (Fruhstorfer, 1921). After further investigation of external morphology and the male genitalia, confirmation was derived about its undescribed status of the specimens and the species is here formally described and illustrated as Miramella demissa sp. nov. The new species is known from a restricted area in southern Montenegro. It is adapted to particularly low elevations, quite aberrant for the genus. A key to both sexes is given for the species in the region.

Damsel bugs (Hemiptera, Nabidae) are predatory insects belonging to the order of Hemiptera. During the spring-summer of 2021–2022, nabid specimens were collected from Guilan province and adjacent areas. In this study, three species (four subspecies) belonging to two genera were collected and identified: Himacerus mirmicoides (O.Costa, 1834); Nabis viridulus Spinola, 1837; Nabis pseudoferus pseudoferus Remane, 1949 and Nabis pseudoferus orientarius Remane, 1962, furthermore, four species (four subspecies) belonging to two genera were examined from the insect collection of the Natural History Museum of the University of Guilan (UGNHM) including Himacerus major (A.Costa, 1842); Nabis pseudoferus transcaspicus Remane, 1962; Nabis punctatus punctatus A.Costa, 1847 and Nabis capsiformis Germar, 1838. In this paper, based on the morphological characteristics and genitalia of males, brief diagnostic descriptions, illustrated identification key and digital images of species habitus were provided to facilitate the identification of Nabidae of Guilan province and its adjacent areas.

The New World insect species Frankliniella minuta (Moulton, 1907) is reported from Asia for the first time. This is a member of the Order Thysanoptera and is placed in the subfamily Thripinae of the Thripidae. A total of 45 female and 14 male adults were found on Tridax procumbens (Asteraceae) at the Malaysian Agricultural Research and Development Institute (MARDI) in Selangor, Peninsular Malaysia. Both sexes were taken from the capitula of T. procumbens. The potential threat of this species to the horticultural industry is inconclusive, but the discovery will alert horticulturalists and quarantine entomologists to possible invasion pathways. Diagnostic characters, relevant figures and a key to Frankliniella species in Malaysia are provided.
