Monophyly of Cerurinae is corroborated, which includes the following genera: Pararethona Janse, Pseudorethona Janse, Oreocerura Kiriakoff, stat. rev., Cerurella Kiriakoff, Notocerura Kiriakoff, Hampsonita Kiriakoff, Afrocerura Kiriakoff, Cerurina Kiriakoff, Neoharpyia Daniel, Furcula Lamarck, Neocerura Matsumura, Americerura St Laurent and Goldstein, gen. nov., Cerura Schrank, and Kamalia Koçak & Kemal. The type species of the Neotropical genus Tecmessa Burmeister, T. annulipes (Berg), which had been incorrectly assigned to Cerurinae, is recovered in Heterocampinae; and Americerura gen. nov. is proposed to receive 17 unambiguously cerurine species transferred from Tecmessa. Divergence time estimates recover a crown age of Notodontidae roughly coincident with the K-Pg boundary, and a late-Oligocene crown age for Cerurinae. An African origin is inferred for Cerurinae, followed by colonization of the Palearctic, the Americas, Indomalaya, and Australasia during the Miocene. At least three independent colonizations of the Americas are inferred, one in the mid-Miocene associated with ancestral Americerura gen. nov. and two in the Pliocene and Pleistocene within Furcula. We hypothesize that the global spread of Cerurinae was enabled by that of its primary caterpillar foodplants in the Salicaceae. State-dependent diversification analyses suggest that cerurines diversified most rapidly in temperate climates.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"7 1","pages":"1 - 25"},"PeriodicalIF":3.4,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42360938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gland is one of the most researched exocrine glands in arthropods and its anatomy, ultrastructure, and chemistry are well documented. Herein, we describe an exocrine gland from the proctotrupoid wasp Pelecinus polyturator (Hymenoptera: Pelecinidae) with a similar position, structure, and chemistry to the ant metapleural gland: it is located just above the hind coxa, corresponds to an externally concave and fenestrated atrium, is composed of class 3 gland cells, and its extract contains relatively strong acids. We discover that the pelecinid gland is associated with the dilator muscle of the first abdominal spiracle, a trait that is shared with ants, but remained overlooked, possibly due to its small diameter, or obfuscation by the extensive metapleural gland. We also provide a biomechanical argument for passive emptying of the gland in both taxa. Pelecinids and ants with metapleural glands share a close association with soil. The pelecinid metapleural gland might therefore also have an antiseptic function as suggested for ants. We examined 44 other Hymenoptera families and found no glands associated with the oclusor apodeme or any signs of external modification. Our results strongly indicate that this complex trait (anatomical & chemical) evolved independently in ants and pelecinid wasps providing an exceptional system to better understand exocrine gland evolution in Hymenoptera.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"7 1","pages":"1 - 10"},"PeriodicalIF":3.4,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45949199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Population analyses indicate that most colonies consist of multiple cohorts formed by close relatives.Territorial social spiders facultatively form colonies by interlinking individual webs, but further cooperation is infrequent, and only among juveniles or (rarely) females. In spiders therefore, aggregations of males outside of the male-male competition context has been unknown. Here, we report on a discovery of a kite spider from Madagascar that exhibits unique colonies. We found colonies of the newly described araneid Isoxya manangona n. sp. formed by up to 41 interconnected, single-cohort adult female webs with up to 38 adult males aggregating on a central, single, nonsticky line. With males resting tightly together, we found no evidence for male-male aggression. Genetic analyses from RAD sequencing suggest that most colonies consist of unrelated individuals. Furthermore, genetic variability of males was somewhat less than that of females. Single cohort colonies made up purely of adults, and peaceful male aggregations, have not previously been observed in spiders. Although direct behavioral observations are preliminary, we speculate based on the available evidence that these colonies may represent a novel and first case of lekking in spiders.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"7 1","pages":"1 - 15"},"PeriodicalIF":3.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"61455806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because species living in tropical regions experience potentially higher risks of predation than those in temperate climes, we hypothesized that variable risk might explain this variability. We used actual evapotranspiration (AET) rates as a stand-in for climate, region, and potential interactions with natural enemies. We predicted that more complex investments, such as coating individual eggs, organizing them, and topping the cluster with thick silk would co-occur with greater predation threats in tropical regions, scored as higher AET. We predicted that simpler organization of eggs would occur where predator risk would be lower, as in temperate regions (lower AET). We used phylogenetic comparative methods to assess whether more complex egg handling behavior correlated with high AET scores. We quantified five traits of egg handling from field and laboratory evidence for 29 species from habitats ranging from low to high AET. Initial pGLS and pGLM analyses showed a weak effect of AET on parental care index. Upon exclusion of three exotic species spread artificially by trade and collected outside their native ranges, we found strong effects of predation threat in both pGLS and pGLM analyses. These analyses revealed that species that experience potentially greater predation threats exhibited behaviors that corresponded to more complex handling and organization of eggs by the mother. These results align nicely with analyses that also detected that additional lines of defense of eggs typify the behavior of tropical species of other primitively social arthropods.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"7 1","pages":"1 - 11"},"PeriodicalIF":3.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41599837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to immature stages of other holometabolous groups, the second instar increases dramatically in size. Compound eyes and external wing anlagen are present in male larvae before the pupal stage. In contrast to the females, the brain of males bears well-developed optic neuropils and retinula cells are present.The cephalothorax is comparatively simple in the female larvae, yet distinctly more complex than in the adult, where most muscles are reduced. Large testes are present in male larvae and numerous oocytes in the females, but they are still immature.The larval features are discussed in the context of holometabolous development and heterochronic processes. Unique features of Strepsiptera are the early differentiation of the sexes and the occurrence of compound eyes and external wing anlagen in male secondary larvae. The phylogenetic position of Strepsiptera suggests that this is a secondary feature and thus an autapomorphy.

The ABB was listed as a federally endangered species in 1989 with remaining distribution in only six U.S. States. Within these states, populations of ABB are disjunct, occurring in mostly undisturbed habitats associated with multiple soil types and vegetation structure. In Nebraska, the distribution of the ABB has been mapped in two ecoregions, the Sandhills and the Loess Canyons. In this project, we developed and compared a logistic regression model and a random forest model of ABB distribution at its northern and eastern edge in the Northern Plains ecoregions of Nebraska and South Dakota. We used baited pitfall sampling for five trap nights at 482 unique sites to establish presence of ABB at 177 sites. Distribution was not uniform in this ecoregion and the random forest model better predicted occurrence in this area.The results show that the ABB population in the northern plains ecoregion is unique from the previous model of the Nebraska Sandhills despite these ecoregions being adjacent. The model results also reduce requirements to survey and conduct habitat mitigation for ABB in approximately 77,938 hectares of Nebraska and South Dakota that was considered potential habitat while prioritizing areas for conservation.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"2 1","pages":"1 - 8"},"PeriodicalIF":3.4,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/isd/ixx011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42580981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ancient, relictual scorpion family Pseudochactidae Gromov 1998 has a disjunct distribution and includes two hypogean subfamilies from caves in the Khammouan-Phong Nha-K Bàng Karst in the northern Annamite (Trưng Sơn) Mountains of Laos and Vietnam, and one epigean subfamily from Central Asia. A recent revision identified six species in the family; however, how these taxa dispersed and diversified into Southeast Asian cave systems has not been tested. In the present contribution, the phylogeny of Pseudochactidae is reconstructed using three mitochondrial and three nuclear markers and 140 morphological characters, divergence time and ancestral range estimation analyses are conducted, and the evolution of troglomorphic characters is investigated. Results confirm a previous hypothesis that Pseudochactidae originated in Eurasia, most likely near the Tajik block in the Carboniferous, supporting the ‘Out of Eurasia’ hypothesis and contradicting the ‘Eurogondwana’ and ‘Out of India’ hypotheses for the origin of Southeast Asian scorpions. Pseudochactidae dispersed across Southeast Asia after the collision of the Cimmerian continent and Indochina with Eurasia in the Late Jurassic. Colonization of Southeast Asian caves began in the Late Cretaceous and was completed by the Miocene. The onset of aridification in Southeast Asia during the Late Miocene resulted in the extinction of epigean Pseudochactidae, whereas hypogean members of the family likely survived within caves in the limestone massifs of the Annamite Mountains, supporting the ‘Climate Relict’ hypothesis.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"6 1","pages":"1 - 21"},"PeriodicalIF":3.4,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42736698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A stable classification and reliable identification of genera and species of these pests and their 1,700 relatives are of great relevance for trade restrictions, biosecurity, pest management, forensics, and biodiversity surveys. In this study, we examined and sequenced mitochondrial genomes of 477 dermestid specimens, representing all subfamilies and 90% of the globally recognized tribes and subtribes. Our study provides the most comprehensive, taxonomically verified, and vouchered resource of mitochondrial reference sequences linked to specimen images and occurrence records of pests and their relatives, enabling eDNA surveys, metabarcoding and molecular species identification. It also reconstructs the phylogeny of Dermestidae based on molecular and morphological data for the first time, thereby providing robust phylogenetic hypotheses for a stable classification system from family to genus-level. Accordingly, a revised classification of Dermestidae with formal nomenclatural changes is proposed, recognizing six subfamilies: Orphilinae, Trinodinae, Trogoparvinae subfam. nov. (type genus Trogoparvus Háva, 2001), Dermestinae, Attageninae, and Megatominae. Trinodinae is recovered towards the base of Dermestidae with three tribes: Trinodini (=Trinoparvini syn. nov.), Thylodriini, and Trichelodini. Dermestinae is the only subfamily with adults lacking a median ocellus, and it includes the tribes Thorictini stat. nov. (that is downgraded from Thorictinae), Marioutini, and Dermestini. The endemic Australian genus Derbyana Lawrence and Ślipiński was recovered within Holarctic Dermestes Linnaeus. Attageninae is strongly supported and includes the monogeneric Adelaidiini and polygenic Attagenini. Former subgenera of Attagenus Latreille, i.e., Lanorus Mulsant and Rey (= Paranovelsis Casey syn. nov.), Telopes Redtenbacher and Aethriostoma Motschulsky, are elevated to generic level. The largest clade, Megatominae, is confirmed as monophyletic and is divided into three tribes: Anthrenini, Ctesiini, and Megatomini. Megatomini is divided into three subtribes: Megatomina, Orphinina subtribe nov. (type genus Orphinus Motschulsky), and Trogodermina. Within the economically important lineage Trogodermina, Trogoderma Latreille is delimited to contain only Holarctic species including the Khapra beetle T. granarium Everts, while a Southern Hemisphere clade is here recognized as Eurhopalus Solier in Gay, 1849 (= Anthrenocerus Arrow, 1915; Myrmeanthrenus Armstrong, 1945; Neoanthrenus Armstrong, 1941; Sodaliatoma Háva, 2013; Reesa Beal, 1967 syn. nov.).

From Luzon northward to Taiwan lies a series of isolated volcanic islands (the Taiwan–Luzon volcanic belt) where three Pachyrhynchus species [P. sarcitis (Behrens, 1887), P. nobilis (Heller, 1912) and P. semperi (Heller, 1912)] (Coleoptera: Curculionidae: Entiminae: Pachyrhynchini) are sympatrically distributed. With intraspecific color variation across different islands, these three weevil species provide a unique opportunity to study genetic divergence associated with geographic isolation and/or phenotypic differences. In this study, genome-wide single nucleotide polymorphism (SNP) data derived from ddRAD-seq was used to reconstruct the speciation history and to delimit species within each of the three species. Our results indicate all three species have ancient diversification histories in southern islands of the Taiwan–Luzon volcanic belt instead of more recent diversification histories in northern islands. Ancestral effective population size estimations also support a scenario of a series of founder colonization events from southern to northern islands in the volcanic belt. Most island populations are monophyletic, and early-divergent populations with deep genetic structures are supported statistically as distinct species. However, color variations could occur between populations with very recent diversification, indicating a fast-evolving rate in the change of coloration, possibly due to müllerian mimicry or founder effects across this region.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":"1 - 14"},"PeriodicalIF":3.4,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45779157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
