Confirming the position of Anthophorinae—a diverse, globally distributed lineage of apid bees—has been particularly problematic, with the subfamily recovered in various conflicting positions, including as sister to all other Apidae or to the cleptoparasitic Nomadinae. We aimed to resolve relationships in Apidae and Anthophorinae by combining dense taxon sampling, with rigorous phylogenomic analysis of a dataset consisting of ultraconserved elements (UCEs) acquired from multiple sources, including low-coverage genomes. Across a diverse set of analyses, including both concatenation and species tree approaches, and numerous permutations designed to account for systematic biases, Anthophorinae was consistently recovered as the sister group to all remaining Apidae, with Nomadinae sister to (Apinae, [Xylocopinae, Eucerinae]). However, several alternative support metrics (concordance factors, quartet sampling, and gene genealogy interrogation) indicate that this result should be treated with caution. Within Anthophorinae, all genera were recovered as monophyletic, following synonymization of Varthemapistra with Habrophorula. Our results demonstrate the value of dense taxon sampling in bee phylogenomics research and how implementing diverse analytical strategies is important for fully evaluating results at difficult nodes.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47652277","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}

Smith, A. Cognato","doi":"10.1093/isd/ixac014","DOIUrl":"https://doi.org/10.1093/isd/ixac014","url":null,"abstract":"Abstract Pseudocryptic species, those that are difficult to diagnose using traditional taxonomic methods, are serious impediments for recognizing the introduction of non-native species. Rapid identification of species facilitates a rapid response to newly introduced species which can lessen their damaging effects. This situation is acute for known pest species such as xyleborine ambrosia beetles which are difficult to identify given minute morphological, often variable, diagnostic characters. These beetles have been introduced into non-native temperate regions and have caused economic and ecological havoc. In this study, we produced DNA-based phylogenies using four genes for individuals of Cyclorhipidion bodoanum (Reitter, 1913), C. distinguendum (Eggers, 1930), and C. pelliculosum (Eichhoff, 1878) sampled from their introduced and native Asian ranges and as well as other Cyclorhipidion species. In addition, we review subtle morphological characters for diagnostic potential for these similar species. Bayesian phylogenetic analysis produced well-resolved and supported phylogeny that provided evidence for multiple introductions of C. bodoanum and C. distinguendum into the United States and the occurrence of pseudocryptic species. The ambrosia beetles Cyclorhipidion tenuigraphum (Schedl, 1953) and C. nemesis Smith & Cognato, sp. nov. are reported in North America for the first time. We find that the pattern of elytral interstrial setae is an unrealized source for the identification of Cyclorhipidion species. This study resulted in the recognition of six species adventive to the United States with the revised status of C. californicum (Wood, 1975). All species known from North American are diagnosed, illustrated and a key is provided.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49211690","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}

Here we present a comprehensive systematic revision and mitochondrial phylogenomic analysis to clarify the identity of this genus, and to unravel its evolutionary history. Combining morphological and molecular evidence, we found that the species currently placed in Gatzara belong to two clades, and most of the Gatzara species are considered to be affiliated to the genus Nepsalus Navás, 1912. The dated phylogeny with ancestral area reconstruction indicates that the common ancestor of Gatzara and Nepsalus might have been widely distributed in East Asia and these two genera may have diverged during the late Miocene. The speciation of most Nepsalus species that are allopatric in distribution might have been driven by a series of vicariance events related to the rise of the Himalayas and the formation of the major islands of East Asia during the late Miocene and Pliocene. A new species, namely Nepsalus chikuni sp. n., is described from Tibet.

{"title":"Assessing the Old-Growth Dependency of Two Saproxylic Beetle Species in the Southern Appalachian Mountains","authors":"Clayton R. Traylor, M. Caterino, M. Ulyshen, M. Ferro, Joseph V. McHugh","doi":"10.1093/isd/ixac012","DOIUrl":"https://doi.org/10.1093/isd/ixac012","url":null,"abstract":"Abstract The southern Appalachian Mountains were intensively logged during the early 1900s, leaving little remaining old-growth forest. Much of the region is now second-growth forest, which may not be suitable to specialist saproxylic species. Moreover, if suitable habitat exists, poorly dispersing species may not be able to colonize it. To investigate this, we assessed the distribution and old-growth dependency of two low-mobility saproxylic beetles in Great Smoky Mountains National Park. Using both field surveys and community science data, we found Megalodacne heros (Say 1823) (Coleoptera: Erotylidae) to be limited to lower elevations regardless of disturbance history, while Phellopsis obcordata (Kirby 1837) (Coleoptera: Zopheridae) was restricted to inside or near old-growth forests. Although trees were generally smaller in second-growth, we detected no habitat limitation for P. obcordata: fungal hosts were present in second-growth areas and the beetle was present on trees as small as 11 cm in diameter. This suggests its distribution is shaped by its low dispersal capability and need for temporal continuity of deadwood habitat, therefore qualifying it as an indicator species. For P. obcordata, old-growth acted as refugia during landscape-wide, anthropogenic disturbances in the early 1900s, though we can draw no conclusions about M. heros from our dataset. The difference in sensitivity to human disturbance displayed between species may be linked to their relative dispersal abilities: P. obcordata is entirely flightless while M. heros is capable of some flight. This study highlights the value of using saproxylic invertebrates with limited dispersal ability for assessing impacts from anthropogenic forest disturbances.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41727254","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}

Members of most extant dryopoid families are set apart from the majority of other polyphagans by their association with aquatic habitats, but little is known about the origin of these derived life habits and the phylogeny of the superfamily. Here we describe Mastigocoleidae Tihelka, Jäch, Kundrata & Cai fam. nov., a new family of Mesozoic dryopoids represented by fossils from the Cretaceous Yixian Formation in northeastern China (undescribed species; ~125 Ma), Crato Formation in northeastern Brazil (Mastigocoleus rhinoceros Tihelka & Cai gen. et sp. nov.; ~113 Ma), and amber from northern Myanmar (Mastigocoleus resinicola Tihelka & Cai gen. et sp. nov. and Cretaceocoleus saetosus Tihelka, Kundrata & Cai gen. et sp. nov.; ~99 Ma). Integrating the findings of recent molecular and morphological phylogenetic analyses, we recover Mastigocoleidae as an early-diverging dryopoid clade sister to the families Lutrochidae and Dryopidae, or less likely as a group of putative stem-dryopoids. Mastigocoleidae are most distinctly separated from all other dryopoid families by their whip-like antennae, with 11 antennomeres, reaching to the pronotal base, and with the scape broadest and longest, a short pedicel, and antennomeres II–XI more or less distinctively gradually tapering toward the apex. Mastigocoleidae indicate that the last common ancestor of Dryopoidea was likely terrestrial in the adult stage, and document character acquisitions associated with a specialization for aquatic life.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45062473","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}

One of the most widespread species is Melitaea ornata Christoph, 1893, present from France (Provence) to Central Asia. Recently, populations of M. ornata were discovered in a mountainous region of south-eastern Iberia, although doubts about their taxonomy existed. To clarify the taxonomic status of these populations and to revise the distribution of this taxon in Iberia, we have sequenced mitochondrial (COI barcode region) and nuclear (wg, RPS5, MDH, and EF-1α) markers, and analyzed the male genitalia for 72 Iberian individuals and for all the species of the M. phoebe group. This information was complemented with phenological and ecological data. Our results unveiled that the Iberian M. ornata-like taxon is in fact distributed through most of the Iberian Peninsula, except for the south-west and north-east. In contrast to the univoltine M. ornata, the Iberian taxon can be bivoltine in the wild. The Iberian taxon was retrieved to be related to M. ornata, but the differences in the genetic markers and genitalia were comparable to those found between species in the group. Based on the evidence here presented and according to species delimitation results, we propose to consider the Iberian taxon as a novel species, tentatively named Melitaea pseudornata Muñoz Sariot & Sánchez Mesa, 2019, stat. nov.

Una de les espècies més esteses és la Melitaea ornata Christoph, 1893, present des de França (Provença) fins a l'Àsia Central.

Amb l'objectiu d'esclarir l'estatus taxonòmic d'aquestes poblacions i revisar la distribució d'aquest tàxon a la península Ibèrica, hem seqüenciat els marcadors mitocondrials (regió del codi de barres del COI) i nuclears (wg, RPS5, MDH i EF-1α) i hem analitzat la genitàlia masculina de 72 individus ibèrics i de totes les espècies del grup de M. phoebe.

It has been hypothesized that adaptation to ground locomotion and the loss of flight led to the substantial rearrangements in the mesosoma in worker ants and that it is likely the ant mesosoma has undergone functional modifications as ants diversified into different ecological and behavioral niches. Despite this importance, studies on the anatomy of the ant mesosoma are still scarce, and there is limited understanding of important variation of internal structures across the ant phylogeny. Recent advances in imaging techniques have made it possible to digitally dissect small insects, to document the anatomy efficiently and in detail, and to visualize these data in 3D. Here we document the mesosomal skeletomuscular system of workers of the red wood ant, Formica rufa Linnaeus, 1761, and use it to establish a 3D atlas of mesosomal anatomy that will serve as reference work for further studies. We discuss and illustrate the configuration of the skeletomuscular components and the function of the muscles in interaction with the skeletal elements.
