During the study of aphid fauna of North-Khorasan province, Iran, an aphid species, Brachycaudus cerasicola (Mordvilko, 1929) (Hem.: Aphididae), was collected on Salvia aethiopis, Stachys turcomanica, Hymenocrater elegans, Perovskia abrotanoides and Phlomis cancellata (Lamiaceae) in 2016 and 2017 which is reported here for the first time from Iran. The first to third host plants reported as the new hosts for this aphid. Since the original descriptions of this species by Mordvilko (1929) and Shaposhnikov (1964) are rether brief, so we report here additional notes and more detailed biometric data on this species. The biometric data of the Iranian populations of B. cerasicola is given and compared to the original descriptions.

A three-year survey of species in the Superfamily Pentatomoidea was conducted during March and November of 2018 through 2020 in Tartous Province, Syria. The identified specimens belonging to four families; i.e. Pentatomidae (21 species), Scutelleridae (2 species), Dinidoridae and Cydnidae each with one species. This is the first faunistic study on the Pentatomoidea in the coastal area of Syria, Tartous. The results represented the first records of Tritomegas sexmaculatus (Rambur, 1839) and its host plants in Tartous, here considered as a newly recorded species for fauna of Syria.

In this study, the Iranian specimens of the cixiid tribe Cixiini (genera Cixius Latreille and Tachycixius, Wagner) housed in Hayk Mirzayans Insect Museum (HMIM) were examined. The examined specimens were collected and deposited in HMIM since 1970 including our recent studies and collecting trips since 2007. Cixius remotus Edwards, 1888 is a new record for the fauna of Iran. An Identification key to the genera and species, and distribution maps for the species in the tribe Cixiini present in Iran are provided and zoogeographic implications are discussed.

The genus Cicadula Zetterstedt is reported for the first time from Pakistan with a newly recorded Cicadula simlaensis Viraktamath & Yeshwanth. In addition, Platymetopius fidelis (Distant) is also rediscovered from Pakistan and studied here. A brief diagnosis along with the digital photographs of the habitus and male genitalia of both species are provided. General distribution of these species in both Palaearctic and Oriental regions is also briefly discussed.

The diversity and distribution of aquatic and semi-aquatic Hemipterans were studied from Amrabad and Kawal Tiger Reserve of the state Telangana. This report documents 38 species of aquatic and semi-aquatic hemipterans belonging to 22 genera and ten families from Amrabad and Kawal Tiger Reserve. Interestingly, 20 species were noted as additions to the state of Telangana. Two species Ranatra libera Zettel, 1999 and Rhagovelia sumatrensis Lundblad, 1933 were observed, where both species are new distributional records to peninsular India. Kawal Tiger Reserve (KTR) showed higher species diversity than the Amrabad Tiger Reserve (ATR) with respect to species richness. The present report is the first documentation from both tiger reserves on aquatic and semi-aquatic hemipterans from the state of Telangana.

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.

This study reports the discovery of Corythucha arcuata (Say), a species previously unrecorded in the Republic of Kosovo. Nine individuals of this species were collected from an Oak tree during the investigation. The findings presented in this study enhance our knowledge of the distribution of C. arcuata within the Balkan region. This discovery underscores the importance of further research to elucidate the factors governing the presence or absence of this species in specific areas. Also, herein we made a list of all known alien-invasive species to Kosovo.

Planococcus Ferris (Hemiptera: Coccomorpha, Pseudococcidae) is a genus of mealybug containing 49 species worldwide. Many species of Planococcus are important pests of agricultural crops. Surveys have been set up in Bengkulu Province, Sumatra-Indonesia, on coffee plantations, in 2023. Planococcus bengkuluensis Zarkani & Kaydan sp. nov. was found in association with Coffea robusta Lindl. ex De Will. (Rubiaceae), described and illustrated. The new species has multilocular disc pores and oral collar tubular ducts on the posterior dorsum in limited numbers. It is another species of Planococcus possessing dorsal multilocular disc pores. An identification key to the known Planococcus species of southern Asia is also provided

Aphids constitute a significant cohort of herbivorous insects, primarily nourishing themselves by extracting plant sap, sometimes posing a notable threat to plant health. Here, we present a comprehensive investigation into the aphid fauna associated with Carthamus in Iran, unveiling 18 species across 11 genera within the Aphididae. Furthermore, 31 associations between aphid species and host plants were recognized, of which two are new for Iran. Our study expands upon prior knowledge by documenting three new occurrences, shedding light on previously unrecorded aphid species in Isfahan and Razavi Khorasan provinces. In addition, we describe the previously unknown male of Uroleucon carthami, offering insights into its life cycle and reproductive strategies. An identification key to the apterous viviparous female aphids living on Carthamus in Iran is provided.

Illustrations of the habitus and diagnostic characters of the new species are presented. It most resembles P. shaanxiensis Wang & Wei, 2014 from Shaanxi, China. Diagnostic characters of the two species are compared in detail. Platylomia insignis Distant, 1912 and P. operculata Distant, 1913 are commented on their distributions in China, and P. strongata Lei, 1997 is proposed as an unavailable name and a nomen nudum. In addition, an updated list of all 23 known species of the genus Platylomia are presented.

During the spring-summer of 2020–2022, field investigations were conducted in the diverse climate regions along the southern shore of the Caspian Sea. Examination of the sampled material resulted in the finding of Acetropis carinata (Herrich-Schaeffer, 1841) as a new genus and species for the Iranian fauna. Additionally, four more species were found: Leptopterna inopinata Vinokurov, 1982 and Stenodema (Brachystira) pilosa (Jakovlev, 1889) in Ardabil province, Stenodema (Stenodema) virens (Linnaeus, 1767) in Ardabil and Guilan provinces, and Megaloceroea recticornis (Geoffroy, 1785) in Mazandaran province. Measurements, distributional information, dorsal and lateral habitus photographs, illustrations of male and female genitalia, as well as diagnoses and redescriptions are provided for the new country and province records. A revised key was compiled for the identification of all Stenodemini genera currently known from Iran.
