The larval stage of the species presents a high incidence of intoxication outbreaks in South America with an important economic impact on cattle, sheep, and pig production. Examined specimens were collected from the southern and northern extremes of the species distribution. Southern-limit specimens from Uruguay and Brazil were used to amplify and sequence COI, 16S, and 28S genes, and the same gene sequences were obtained from the Genbank database for the northern limit in Colombia, together with three other species of the Pergidae group. High similarity between Brazilian and Uruguayan samples was found. Colombian haplotypes were highly differentiated from those of the Uruguay-Brazil group. Paired differences between Perreyia species were similar to those found between southern and northern comparisons of P. flavipes, suggesting the need to deeply understand and describe the incipient differentiation of the species across its wide geographic distribution.https://jibs.modares.ac.ir/article_28697_46a62c34c7b8b0c0d02f0833df49ec20.pdfThe Entomological Society of IranJournal of Insect Biodiversity and Systematics2423-811212320260901Annotated catalogue of the tortoise beetles (Coleoptera: Chrysomelidae: Cassidinae) from Indonesia with additional faunistic data from Museum Zoologicum Bogoriense5776092878810.48311/jibs.12.03.577ENAnang SetyoBudiMuseum Zoologicum Bogoriense, Research Center for Biosystematics and Evolution, National Research and Innovation Agency 16911 Cibinong, Bogor, West Java, Indonesia0000-0003-0578-7861JolantaŚwiętojańskaDepartment of Biodiversity and Evolutionary Taxonomy, University of Wrocław, Przybyszewskiego 65, 51-148 Wrocław, Poland0000-0002-6701-8809Journal Article20251216An annotated catalogue of tortoise beetles from Indonesia is presented.

Hibiscus species (Malvaceae) are frequently attacked by different mealybug species globally. Nevertheless, little information is available concerning the mealybug fauna associated with H. rosa-sinensis in Malaysia. The aim of this study was to identify the mealybug species infesting the H. rosa-sinensis by morphological and DNA barcoding. The DNA barcoding study was performed by comparing the sequencing of the universal barcode DNA region, cytochrome c oxidase subunit I (COI), and ribosomal (18S and 28S). The nucleotide sequences confirmed the mealybug species, with the closest BLAST match in the GenBank queries sharing above 97% support. Based on taxonomic characterization by using scanning electron microscopy and DNA barcoding, three mealybug species, Paracoccus marginatus, Maconellicoccus hirsutus, and Phenacoccus solenopsis were confirmed in this study. DNA barcoding, along with the detailed external ultra-structural analysis of the mealybugs, could add a new dimension for identifying the mealybug species rapidly and more accurately. Ultimately, this study will help in decision-making in management practice for mealybugs.https://jibs.modares.ac.ir/article_28828_bb2dba24644723c5ee4d687215836391.pdfThe Entomological Society of IranJournal of Insect Biodiversity and Systematics2423-811212320260901New findings of the family Scelionidae (Hymenoptera: Platygastroidea) in East Azerbaijan province, Iran6456562892610.48311/jibs.12.03.645ENMortezaShamsi Agha-aliDepartment of Plant Protection, Faculty of Agriculture, University of Tabriz, Tabriz, Iran.0000-0003-4741-8431SamadKhaghaniniaDepartment of Plant Protection, Faculty of Agriculture, University of Tabriz, Tabriz, Iran.0000-0002-9787-098XShahzadIranipourDepartment of Plant Protection, Faculty of Agriculture, University of Tabriz, Tabriz, Iran.0000-0002-1987-4758ElijahTalamasFlorida Department of Agriculture and Consumer Services, Gainesville, FL, USA.0000-0002-1048-6345Journal Article20251030This study, conducted between 2022 and 2023, investigated the fauna of parasitoids in the family Scelionidae in the north of East Azerbaijan Province, Iran.

The spotted alfalfa aphid parasitoid Praon exsoletum (Nees) (Hymenoptera: Braconidae, Aphidiinae) exhibits considerable intraspecific morphological variability, and its taxonomic status, whether it comprises distinct subspecies or geographic biotypes, has long been debated. A previous morphometric study failed to separate geographic populations, prompting the present molecular and ecological investigation. Here, we analyzed the mitochondrial COI barcode region from four biotypes: two from Iran (east and west) and two external (Spain and USA, the latter historically referred to as Praon palitans (Muesebeck), with Praon volucre (Haliday). Phylogenetic analyses using Maximum Parsimony, Minimum Evolution, Maximum Likelihood, and Bayesian Inference consistently placed the Iranian biotypes in a separate subclade from the European and American ones, though node support was generally weak across all methods (bootstrap values 33–78%; posterior probabilities 52–58%). Within Iran, sequences were identical, and overall genetic distances were very low (K2P: 0.0% within Iran, 0.3–0.5% between Iran and external biotypes). Canonical Correspondence Analysis (CCA) of 15 Iranian field sites, incorporating three parasitoid species, P. exsoletum, Trioxys complanatus Quilis, and Aphidius smithi Sharma & Subba Rao, and environmental variables (altitude, climate type, geographical direction), revealed no significant species–environment relationships. Despite the lack of statistical significance, T. complanatus tended to associate with hot, dry, south eastern sites, while P. exsoletum was broadly distributed. The discordance between genetic structure and morphological uniformity suggests that Iranian populations of P. exsoletum may represent an evolutionarily distinct lineage in the early stages of divergence, but the evidence is insufficient to support formal subspecific recognition. This study highlights the need for nuclear markers and finer scale ecological data to fully resolve the status of this important biological control agent.https://jibs.modares.ac.ir/article_29029_25b3a3d4f23eec4263e495f5181e207f.pdfThe Entomological Society of IranJournal of Insect Biodiversity and Systematics2423-811212320260901New data on Opilio Herbst, 1798 (Opiliones, Phalangiidae) from Russia and Kyrgyzstan6736812904510.48311/jibs.12.03.673ENNatalySnegovayaInstitute of Living Systems Research, of the Ministry of Science and Education of the Republic of Azerbaijan, passage 1128, district 504, Baku, AZ1004, AzerbaijanWestern Caspian University, Istiglaliyyat str., 31, Baku, AZ1001, Azerbaijan0000-0001-6060-6491Journal Article20260522Two new species of Opilio Herbst, 1798 (Opiliones: Phalangiidae), O. kyrgyzstanicus sp. nov. from Kyrgyzstan and O. zhiguli sp. nov. from Russia, are described based on morphological characters of both sexes. Both species are diagnosed and illustrated in detail, including the structure of the penis, pedipalps, chelicerae, and body armature. The discovery of these new species indicates that the diversity of the genus in the Palaearctic remains considerably underestimated, particularly in poorly studied regions of Central Asia and the Middle Volga.https://jibs.modares.ac.ir/article_29045_49e5149850c506cbe690383f75345b83.pdf
