This paper presents new information on black fungus gnats (Sciaridae) based on field studies at seven localities in Iran. Five sciarid species from the genera Bradysia Winnertz, Corynoptera Winnertz and Lycoriella Frey were collected with Malaise traps, yellow sticky traps, sweep net and an aspirator between 2015 and 2021: Bradysia cellarum Frey, 1948; B. ocellaris (Comstock, 1882); B. tilicola (Loew, 1850); Corynoptera fatigans (Johannsen, 1912); Lycoriella sativae (Johannsen, 1912). All species are first records for the Sistan and Baluchestan province. Bradysia tilicola (Loew) is new to Iran and was recorded for the first time in the Middle East. This brings the number of known sciarid species from Iran to seven. For five species are given a short morphological diagnosis and the global distribution. A map illustrates the distribution of all identified sciarid species in Iran. [ABSTRACT FROM AUTHOR]

Simple Summary: In this paper, we used scanning electron microscopy to describe the morphological types, number of sensilla, and their distributions on the antennae of each nymphal instar and adult of Notobitus meleagris (Hemiptera: Heteroptera: Coreidae). The results show that there were eight subtypes of sensilla on the antennae of the nymphs and 11 subtypes of sensilla on the antennae of the adults. With the growth of instars, the type, quantity, and size of the sensilla gradually increased. Sexual dimorphism did not appear in the type of sensilla but existed in the length and diameter of some sensilla. In addition, we also discussed the functions of different types of sensilla through previous published studies, which will be helpful for further research on the behavioral and biological control of N. meleagris. The bamboo bug Notobitus meleagris (Fabricius, 1787) is a serious pest of bamboo shoots in China, India, Myanmar, Vietnam, and Singapore. The antennae of the nymphal instars and adults of N.meleagris are involved in communication among individuals and finding the host plants. In order to understand the morphology of antennal sensilla, their types, and the distribution of sensilla on the antennae of nymphal instars and adults in N. meleagris, we studied the morphology of antennal sensilla with a scanning electron microscope. The antennae of the nymphs and adults comprised the scape, pedicel, and two flagellomeres. Four types and eight subtypes of sensilla were identified in the nymphal instars (sensilla trichodea [St].1, St.2, St.3, sensilla basiconica [Sb].1, Sb.2, sensilla chaetica [Sc].1, Sc.2, sensilla coeloconica [Sco].1), whereas those of the adults had five types and eleven subtypes of sensilla (St.1, St.2, St.3, Sb.1, Sb.2, Sb.3, Sc.1, Sc.2, Sco.1, Sco.2, and sensilla campaniformia [Sca]). There are significant differences in the number, type, and size of the sensilla in different nymphal instars, which increases with the increase in nymphal instars. There was no sexual dimorphism observed in the adult sensilla; however, the length and diameter of St.3, Sb.2, and Sb.3 were sexually dimorphic. The potential functions of each sensillum were discussed based on the morphology and distribution of the antennal sensilla and were compared with similar published studies. Our results provide primary data for further research on the behavioral mechanism, green prevention, and control of N. meleagris. [ABSTRACT FROM AUTHOR]

BRUCHOPHAGUS ,HYMENOPTERA ,CLASSIFICATION of insects ,INSECT morphology - Abstract
Seed-eater eurytomids of the genus Bruchophagus Ashmead, 1988 were collected from Ardabil and Qazvin provinces in northwest Iran. Various host plants were collected and their seeds were kept in laboratory conditions from 2007 to 2012. Scope of this paper focused on the Bruchophagus species reared from seeds of Astragalus brachydontus Boiss (Fabaceae). We obtained six species of Bruchophagus including B. astragali Fedoseeva. They were B. saxatilis Zerova; B. mutabilis Nikolaskaya; B. nikolskayae (Zerova); B. turkestanicus Zerova, and B. robiniae Zerova. Of which, Bruchophagus saxatilis Zerova, is a new record for the Iranian fauna. New host associations were found for all collected species and it seems a complex biological association that was recorded for the first time. Currently, 11 species of Bruchophagus are occurred inassociated with seeds of A. brachydontus. All previously known species of the genus Bruchophagus in Iran are also tabulated.

An accurate identification of an insect is essential for the effective pest management program. However, due to the restrictions of phenotypic identification, molecular process (e.g. DNA barcoding) is used to overcome some of these limitations. The present paper was aimed to identify the Jujube fruit fly by morphological characters of the adults and molecular DNA barcoding of the larval stage in southeast Iraq. The adults was morphologically identified as Carpomyia incompleta (Becker, 1903) (Diptera: Tephritidae). Results of the molecular method revealed that the mitochondrial COI - COII marker was successfully identified immature stage of the species. The sequence analysis results identified the specimens (AHL1 and AHL2) as C. incompleta. Sequences of the specimens were recorded in The US National Center for Biotechnology Information (NCBI) under accession numbers (ON045002.1 and ON045003.1, respectively. These results were consistent with the phenotypic identification of the Jujube fruit flies. [ABSTRACT FROM AUTHOR]

This article introduces WingSegment, a MATLAB app‐designed tool employing a hybrid approach of computer vision and graph theory for precise insect wing image segmentation. WingSegment detects cells, junctions, Pterostigma, and venation patterns, measuring geometric features and generating Voronoi patterns. The tool utilizes region‐growing, thinning, and Dijkstra's algorithms for boundary detection, junction identification, and vein path extraction. It provides histograms and box plots of geometric features, facilitating comprehensive wing analysis. WingSegment's efficiency is validated through comparisons with established tools and manual measurements, demonstrating accurate results. The tool further enables exporting detected boundaries as FreeCAD macro files for 3D modeling and printing, supporting finite element analysis. Beyond advancing insect wing morphology understanding, WingSegment holds broader implications for diverse planar structures, including leaves and geocells. This tool not only enhances automated geometric analysis and 3D model generation in insect wing studies but also contributes to the broader advancement of analysis, 3D printing, and modeling technologies across various planar structures.

Insect diversity monitoring is crucial for biological pest control in agriculture and forestry. Modern monitoring of insect species relies heavily on fine-grained image classification models. Fine-grained image classification faces challenges such as small inter-class differences and large intra-class variances, which are even more pronounced in insect scenes where insect species often exhibit significant morphological differences across multiple life stages. To address these challenges, we introduce segmentation and clustering operations into the image classification task and design a novel network model training framework for fine-grained classification of insect images using multi-modality clustering and approximate mask methods, named PCAM-Frame. In the first stage of the framework, we adopt the Polymorphic Clustering Module, and segmentation and clustering operations are employed to distinguish various morphologies of insects at different life stages, allowing the model to differentiate between samples at different life stages during training. The second stage consists of a feature extraction network, called Basenet, which can be any mainstream network that performs well in fine-grained image classification tasks, aiming to provide pre-classification confidence for the next stage. In the third stage, we apply the Approximate Masking Module to mask the common attention regions of the most likely classes and continuously adjust the convergence direction of the model during training using a Deviation Loss function. We apply PCAM-Frame with multiple classification networks as the Basenet in the second stage and conduct extensive experiments on the Insecta dataset of iNaturalist 2017 and IP102 dataset, achieving improvements of 2.2% and 1.4%, respectively. Generalization experiments on other fine-grained image classification datasets such as CUB200-2011 and Stanford Dogs also demonstrate positive effects. These experiments validate the pertinence and effectiveness of our framework PCAM-Frame in fine-grained image classification tasks under complex conditions, particularly in insect scenes.

FLEA beetles ,CLASSIFICATION of insects ,INSECT morphology ,INSECT ecology - Abstract
Background: The genus Clavicornaltica Scherer 1974 consists of very small, soil-dwelling flea beetles in South, Southeast and East Asia. Due to their diminutive size and morphological similarities, very little is known about their ecology and taxonomical diversity. It is likely that further studies will reveal this genus to be much more speciose than the 30 species currently recognised. New information: A new species of Clavicornaltica from Brunei Darussalam is described, C. mataikanensis Otani et al., sp. nov. This is the second species of this genus recorded from Ulu Temburong National Park. [ABSTRACT FROM AUTHOR]

SCORPIONS ,SPIDERS ,EYE ,INSECT morphology ,ARACHNIDA classification - Abstract
Scorpions and spiders belong to the class Arachnida in phylum Arthropoda. Scorpions are easily distinguished by median eyes on obvious the center of the carapace and have one pair, and lateral eyes have 2-8 in some species. Scorpions do not have good eyesight so the median eyes have always been simple and they are more sensitive than the lateral pairs. They have anterior median eyes (AME) with narrow field of view and pairs of lateral eyes (LE) with more sensitivity and response to light. Family Buthidae have 2-6 lateral eyes in Compsobuthus Mesobuthus, Hottentotta, while Vaejovidae, Chactidae and Chaerilidae have 2 pairs of lateral eyes. In addition, 3 pairs are found in Orthochirus and Androctonus. Spiders have six eyes in family Pholicidae, Sicariidae, Araneidae, Salticidae, while eight eyes in Theridiidae, Lycosidae and some with two eyes or four in the carapace of the prosoma. Spider have anterior median eyes, anterior lateral eyes, posterior median eyes, or posterior lateral eyes. Scorpions and Spider eyes are not compound but simple. There is one lens for each eye. Spiders have poor vision, not able to see light and darkness. Scorpion and spider taxonomy is based on the forms and number of eyes. So, the reasons to study these organisms are important in studies of medical, ecology, morphology and taxonomy. and it is a little known about their biology and fauna. [ABSTRACT FROM AUTHOR]

Knowledge regarding egg morphology can aid the selection of postharvest fumigants for insect control. Accordingly, scanning electron microscopy (SEM) was used to examine eggs of spotted lanternfly (SLF), Lycorma delicatula (White) (Hemiptera: Fulgoridae), a pest recently invasive to the mid-Atlantic region of the United States. As the overwintering life stage of SLF, eggs are deposited on a variety of refugia, including many forestry products that can be distributed geographically via travel, commerce, and/or trade. For fumigation to control SLF, and potentially translate into a viable strategy for limiting the spread of SLF by subject pathways, the fumigant must permeate the chorion to react with biomolecules and/or disrupt cellular processes. SLF chorion was characterized by a porous network of aeropyles localized around the operculum, in cranial and caudal relation to the developing nymph, as well as an interstice between the operculum edge and the opercular rim. The confirmation of chorionic ultrastructure that allows for ready gas exchange warrants further investigation of fumigation efficacy, even for those "non-reactive" fumigants, such as phosphine and hydrogen cyanide, which must overcome the suppression of cellular processes coincident with overwintering.

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. [ABSTRACT FROM AUTHOR]

NOCTUIDAE ,CLASSIFICATION of insects ,INSECT morphology ,GEOGRAPHICAL distribution of insects - Abstract
The biodiversity of the Noctuidae, an economically important family of Noctuoidea which include major crop pests, is becoming well-identified nowadays in Iran due to the increased number of faunal expeditions. The two large subfamilies of Noctuidae namely Xyleninae Guenée, 1837 and Noctuinae Latreille, 1809 comprise the majority of Iran's noctuid moth fauna. Two species, Leucochlaena hoerhammeri (Wagner, 1931) and Dichagyris (Stenosomides) mansoura (Chrétien, 1911) members of Xyleninae and Noctuinae subfamilies, respectively, are recorded from Iran for the first time. This is also the first record of the subgenus Stenosomides Strand, 1942 from Iran. Both the external and genital characteristics of the newly recorded species are presented together with illustrations of the adults and their genitalia. [ABSTRACT FROM AUTHOR]

Adult caddisflies were collected from the spring area located in the Blinajë Hunting Reserve in Kosovo between May and September 2022. In this study, we identified 21 species belonging to 9 families of caddisflies (Goeridae, Hydropsychidae, Hydroptilidae, Limnephilidae, Philopotamidae, Polycentropodidae, Psychomyiidae, Rhyacophilidae, and Sericostomatidae). The genus Orthotrichia Eaton, 1873 and species Orthotrichia tragetti Mosely, 1930 are reported for the first time from Kosovo. Agraylea sexmaculata Curtis, 1834 is reported from Kosovo again after more than one century. Several other narrowly distributed endemic species were also identified, including Rhyacophila macedonica Karaouzas, Valladolid & Ibrahimi, 2022 and Tinodes janssensi Jacquemart, 1957. This study contributes to the knowledge of the caddisfly fauna of the Blinajë Hunting Reserve in Kosovo and highlights this area for its interesting composition of caddisfly species.

The present study is on the morphology and molecular data of the genus Dineutus MacLeay, were collected from the Eastern Ghats mountains in Odisha, Andhra Pradesh, Telangana, Tamil Nadu states located in the eastern Ghats of India. The morphological identification was based on elytral spines, setation on paramere and structure of the median lobe. Molecular characterization was based on the mitochondrial cytochrome oxidase subunit I (COI) and 16s ribosomal RNA gene. Species identified as being D. indicus, D. spinosus, and D. unidentatus. Phylogenetic trees were constructed for both genes, and the COI fragment shows raw genetic distance between 10-12% among the three species of D. indicus, D. spinosus and D. unidentatus, whereas 16s gene shows a divergence of 4-5%. The present study contributes five novel mitochondrial COI and five ribosomal RNA sequences for D. spinosus and D. unidentatus for the first time from India. [ABSTRACT FROM AUTHOR]

Olfaction is important for mediating aphid behaviors and is involved in host location and mating. Antennal primary rhinaria play a key role in the chemoreception of aphids. The function of the peripheral olfactory system in the subfamily Aphidinae has been intensively studied, but little is known about other subfamilies of Aphididae. Therefore, three aphid species were selected to study the olfactory reception of plant volatiles: Cinara cedri (Lachninae), Eriosoma lanigerum (Eriosomatinae), and Therioaphis trifolii (Calaphidinae). In this study, the morphology and distribution of the antennal sensilla of apterous adults were observed by scanning electron microscopy. Three morphological types were identified (placoid sensilla, coeloconic sensilla, and trichoid sensilla); the first two were distributed on the antennal primary rhinaria. A pattern of primary rhinaria in C. cedri was found that differed from that of E. lanigerum and T. trifolii and consists of 1 large placoid sensillum (LP) on the 4th segment, 2 LPs on the 5th segment, and a group of sensilla on the 6th antennal segments. Later, we recorded and compared neuronal responses of the distinct placoid sensilla in the primary rhinaria of the three aphid species to 18 plant volatiles using a single sensillum recording (SSR) technique. The results indicated that the functional profiles based on the tested odorants of the primary rhinaria of the three investigated aphid species were clustered into three classes, and exhibited excitatory responses to certain types of odorants, especially terpenes. In C. cedri, the ORNs in LP6 exhibited the highest responses to (±)-citronellal across all tested chemicals, and showed greater sensitivity to (±)-citronellal than to (+)-limonene. ORNs in LP5 were partially responsive to a-pinene and (-)-β-pinene in a dose- dependent manner. Across different species, E. lanigerum showed significantly stronger neuronal responses of LP5 to several terpenes, such as (-)-linalool and a-terpineol, compared to other species. In T. trifolii, the neuronal activities in LP6 showed a greater response to methyl salicylate as compared to LP5. Overall, our results preliminarily illustrate the functional divergence of ORNs in the primary rhinaria of aphids from three subfamilies of Aphididae and provide a basis for better understanding the mechanism of olfactory recognition in aphids.

A broad comparative study of insect respiratory morphology is presented. Tracheae, epidermal invaginations extending into the body in branching networks of tubes, supply tissues with direct access to air for gas exchange. While previous tracheal studies focused on a handful of taxa and lacked in consistency, here a unified system of tracheal nomenclature is established using visualizations from micro-CT scanning of representatives from apterygotes, Paleoptera, and Polyneoptera, totaling 29 species, 29 genera, and 26 families in 13 insect orders. Three-dimensional visualizations of named tracheal branches establish robust assessments of homology and provide a framework for further studies across class Insecta. Patterns in respiratory architecture are presented along with a discussion of future investigations into phylogenetic and physiological questions. [ABSTRACT FROM AUTHOR]

The lethal and sublethal effects of Roundup (active substance glyphosate herbicide on phantom midge (Chaoborus flavicans, Meigen, 1830) larvae were checked in the range of concentrations from 20 to 2000 µg/L, in the five-day long tests. The herbicide caused the mortality of insects, with the LC50 values ranging from 357.2 to 120.9 µg of glyphosate/L, for one and five days, respectively. The correlation coefficient >0.9 indicated a strong positive correlation between the concentration of Roundup in water and the mortality of C. flavicans. Also, the LT50 values indicate the toxic activity of the herbicide for the larvae. Also, the reaction to mechanical stimuli was disturbed, in a dose-dependent manner. We also observed the altered vertical migration of midges within the water column. The microscopic observations revealed malformations in insects' morphology and anatomy. Among the most prominent changes were: altered body shape and lower density of chromatophores in air sacs. These changes are in tune with the microscopic observations. We conclude that Roundup 360 Plus herbicide may cause significant changes within C. flavicans populations, especially during long exposure. This, in consequence, may lead to a decline in the population of phantom midges, and next, affect the organisms at the other trophic levels. [ABSTRACT FROM AUTHOR]

The carabid beetle Nebria taketoi Habu, 1962 is endemic to the high-altitude mountains of Honshu, Japan; due to its rarity, it is one of the least taxonomically studied species among Japanese Nebria. This study taxonomically revised N. taketoi based on morphological comparisons, mainly of the endophallus in males, and geometric morphometrics of the pronotum, a taxonomically useful external character. Specimens previously identified as N. taketoi were found to belong to at least two species: N. taketoi, with a currently confirmed distribution in the northern Hida Mountains (type locality: Mikurigaike, Mount Tateyama), and N. kobushicola sp. nov. from the Okuchichibu and Yatsugatake mountains (type locality: Mount Kobushigatake). Species identities in populations from other localities could not be determined, as male specimens for endophallus examinations were unavailable. However, some populations may consist of species distinct from N. taketoi and N. kobushicola, based on their distribution and morphometric features. Based on comparative morphology of the endophallus, N. kobushicola shares features more similar to N. niohozana Bates, 1883 and N. dichotoma Sasakawa, 2020 than to N. taketoi. [ABSTRACT FROM AUTHOR]

Investigations of material collected partly in 1999 and mainly between 2006 and 2016 in New Guinea, mostly along the high, central mountain chain of the island, further increased our knowledge of the diversity of the genus Labiobaetis Novikova & Kluge on this island. Previously, 37 species were reported from New Guinea. We have identified six new species using a combination of morphology and genetic analysis (COI). They are described and illustrated based on their larvae. Five of the six new species belong to the group petersorum, which is endemic to the island. Additionally, Labiobaetis xeniolus Lugo-Ortiz & McCafferty is also assigned to this group. The morphological characterisation of the group petersorum is enhanced, and a key to all species of this group is provided. Complementary descriptions and remarks to the morphology of known species of the group petersorum are provided. Additionally, a genetic analysis (COI) including most species and several additional Molecular Operational Taxonomic Units (MOTUs) of the group petersorum is discussed. One of the new species belongs to the group vitilis. The morphological characterization of this group is slightly enhanced, and the obtained COI sequence was added to the genetic analysis of the group petersorum. The total number of Labiobaetis species worldwide is augmented to 162. [ABSTRACT FROM AUTHOR]

INSECT castes ,CLASSIFICATION of insects ,INSECT morphology ,INSECT evolution ,INSECT genetics - Abstract
Insect caste development and their morphological divergence are not yet studied well, especially in ants. However, the role of developmental and genetic integration in evolution is contentious. In our study, we tried to reveal the quantitative genetics selection responses, phylogenetic signal, and evolutionary origin of weaver ant female castes (queen, major and minor). The widening and lengthening of the head region, as well as the welldeveloped mandibular process, are the major heritable characteristics found in the major worker ants. We hypothesized that these conserved and heritable characteristics may help the major worker ants for defense, foraging purposes and other nest-building function aspects. However, in the case of minor worker, small heads and the reduced mandibular process are the more heritable characteristics. Compared to worker ants, in queen, the highly heritable and conserved morphological character is well-developed thoracic regions and large-sized abdomen. It is interesting to note that there is no detectable phylogenetic signal across the female cast of the Asian weaver ants, which suggests that the caste development and morphological divergence are environmentally modulated not evolutionary conserved. From this study, we concluded that caste-specific morphological shape and size are highly conserved traits and these traits are modulated by their niche preferences. [ABSTRACT FROM AUTHOR]

Tropical mountains display limited variation in monthly temperatures, but high spatial climatic variability. It is assumed this stability promotes ecological and physiological adaptations to local temperatures, which may preclude dispersal up or downslope. Determining how environmental, taxonomic and morphological factors affect thermal limits is fundamental to understand biotic responses to global warming.We selected 54 species of dragonflies and damselflies (Order Odonata) distributed from 300 to 2,550 m along one of the most biodiverse regions on the planet, the Tatamá elevational gradient in the Andean‐Choco region transition. We estimated for 846 individuals three thermal tolerance parameters: CTmax, the highest temperature preceding the loss of motor control, Tvol, the temperature at which individuals avoid heat, and CTmin, the minimum temperature required for wing movement.For each thermal tolerance parameter, we evaluated associations between physiological and behavioural responses, species elevational distribution and specialization to forests or open areas. We also evaluated the effect of autecological characteristics such as body mass, sex and taxonomy on temperature regulation.Temperatures prevalent at different elevations and habitats are associated with odonate upper thermal limits. However, tolerance to low temperatures is not associated with habitat use or elevation. Forest species display lower thermal tolerances. Small species are more tolerant to high temperatures than larger species. Dragonflies are more tolerant to high temperatures than damselflies with similar body mass. Females are more tolerant to high temperatures than males.Our results highlight the importance of considering differences in morphology, life history and behaviour when comparing thermal tolerances of organisms along elevational gradients. Only by incorporating such factors, it would be possible to generate accurate predictions on the impact of climate change on tropical organisms.

This study describes the fine structure of the mouthparts, antennae, forewings, and brochosomes of two leafhopper species belonging to the typhlocybine tribe Erythroneurini collected from the Karst area of Guizhou Province, southern China: Singapora shinshana, which prefers woody dicot hosts, and Empoascanara sipra, which feeds on grasses. As in other leafhoppers, the piercing-sucking mouthparts consist of a conical labrum, a cylindrical three-segmented labium, and a slender stylet fascicle. The labrum of both species has no sensilla and the labium has several common types of sensilla, but the two species differ in the numbers, types, and distribution of sensilla and in other aspects of the surface sculpture of the mouthparts. The stylet fascicle has distinctive dentition on both the maxillary and mandibular stylets. The antennae of the two species differ in several respects, including the sensilla and sculpture of the scape, pedicel, and flagellum, as well as the degree of sub-segmentation of the flagellum. Except for the variable scaly structure and rounded protrusions on the surface of S. shinshana, the fine structure of the forewing surfaces of the two species are similar to those of other leafhoppers. Only small spherical brochosomes were found on the body surface of S. shinshana and E. sipra. Similar studies of additional erythroneurine species are needed to determine whether differences in mouthpart and antennal fine structure may reflect adaptation to different host plant.
