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. This anatomical evaluation of a ‘generalized’ ant provides a template for future studies of the mesosoma across the radiation of Formicidae, with the ultimate objective of synthesizing structural, functional, and transformational information to understand the evolution of a crucial body region of ants.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"6 1","pages":"1 - 26"},"PeriodicalIF":3.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49375897","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}

Vilà","doi":"10.1093/isd/ixac004","DOIUrl":"https://doi.org/10.1093/isd/ixac004","url":null,"abstract":"Abstract The Melitaea phoebe group is constituted by six species distributed throughout the Palearctic. 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. Resum El grup Melitaea phoebe està format per sis espècies distribuïdes arreu del Paleàrtic. Una de les espècies més esteses és la Melitaea ornata Christoph, 1893, present des de França (Provença) fins a l'Àsia Central. Recentment, es descobriren poblacions de M. ornata en una regió muntanyosa del sud-est de la península Ibèrica, tot i que existien dubtes sobre la seva taxonomia. 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. Aquesta informació s'ha complementat amb dades fenològiques i ecològiques. Els nostres resultats revelaren que, de fet, el tàxon ibèric de tipus M. ornata es distribueix per bona part de la península Ibèrica llevat del sud-oest i el nord-est. A diferència de la M. ornata, que és univoltina, el tàxon ibèric pot ser bivoltí a la natura. El tàxon ibèric està relacionat amb M. ornata, però les diferències en els marcadors genètics i la genitàlia foren comparables a les trobades entre les diferents espècies del grup. Degut a aquestes diferències i segons els resultats de la delimitació d'espècies, proposem considerar el tàxon ibèric com a una espècie nova, provisionalment anomenada Melitaea pseudornata Muñoz Sariot & Sánchez Mesa, 2019, stat. nov.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":"1 - 9"},"PeriodicalIF":3.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46433917","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 this study, we used a combination of genotyping-by-sequencing (10,419 SNPs) and mitochondrial COI sequencing to test for population genetic structure within the narrow-range flightless sub-alpine stonefly Zelandoperla maungatuaensis Foster. This species is restricted to only a handful of upland streams along a 4 km stretch of the isolated Maungatua range in southeast New Zealand. We identified striking genetic structure across the narrow range of Z. maungatuaensis, with three deeply divergent allopatric lineages detected. These distinct lineages likely diverged in the early-mid Pleistocene, apparently persisting in separate microrefugia throughout subsequent glacial cycles. Our results illustrate how secondary flight loss can facilitate insect diversification across fine spatial scales, and demonstrate that intraspecific phylogenetic diversity cannot necessarily be predicted from range-size alone. Additional demographic analyses are required to better understand the conservation status of these divergent Z. maungatuaensis lineages, and to assess their potential susceptibility to climate change and other anthropogenic impacts.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"6 1","pages":"1 - 8"},"PeriodicalIF":3.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41820811","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}

Due to its rarity, however, the phylogenetic position, natural history, and fungal associations of the monotypic genus Paramycetophylax Kusnezov have remained enigmatic. Here we report the first excavations of colonies of Paramycetophylax bruchi (Santschi) and describe its nest architecture and natural history. Utilizing specimens from these collections, we generated ultraconserved-element (UCE) data to determine the evolutionary position of Paramycetophylax within the fungus-farming ants and ribosomal ‘fungal barcoding’ ITS sequence data to identify the fungal cultivar. A maximum-likelihood phylogenomic analysis indicates that the genus Paramycetophylax is the sister group of the yeast-cultivating Cyphomyrmex rimosus group, an unexpected result that renders the genus Cyphomyrmex Mayr paraphyletic. A Bayesian divergence-dating analysis indicates that Paramycetophylax diverged from its sister group around 36 mya (30–42 mya, HPD) in the late Eocene-early Oligocene, a period of global cooling, expansion of grasslands, and large-scale extinction of tropical organisms. Bayesian analysis of the fungal cultivar ITS gene fragment indicates that P. bruchi practices lower agriculture and that the cultivar grown by P. bruchi belongs to the Clade 1 group of lower-attine fungi, a clade that, interestingly, also includes the C. rimosus-group yeast cultivars. Based on these results, we conclude that a better understanding of P. bruchi and its fungal cultivar, including whole-genome data, is critical for reconstructing the origin of yeast agriculture, a major transition in the evolution of fungus-farming ants.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":"1 - 17"},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49536332","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}

Ranging from the Great Plains to Patagonia, they are concentrated north and south of the tropics in contrast to the latitudinal diversity gradient canon. Despite being frequently collected and ecologically important, Dorymyrmex ants exemplify the taxonomic neglect typical in the subfamily Dolichoderinae.The genus has never had the benefit of a global revision, and even the major lineages are still uncertain. This work characterizes the issues at hand and ushers 22 Dorymyrmex species into the world of modern-day phylogenomics: By targeting ultraconserved elements (UCEs) across the genome, I construct an alignment of 1,891 loci, infer phylogenies under maximum likelihood and Bayesian approaches, and estimate divergence dates. Three major clades of Dorymyrmex emerge with maximal support, corresponding to former genera: Dorymyrmex sensu stricto, Araucomyrmex Gallardo 1919, and Conomyrma Forel 1913.The pyramicus group (‘Conomyrma’) shows a recent, rapid radiation with minimal morphological differentiation, reaffirming the difficulty of species delimitation in this widespread clade. Finally, I observe a general south-to-north pattern of dispersal, likely by way of savanna ‘stepping stones’ across the tropics during cooler, drier periods. Intercontinental dispersal occurred after the hypothetical Caribbean landspan in the Miocene, but before the Pleistocene or the completion of the Panamanian isthmus, suggesting dispersal by flight.This corroborates patterns observed in other arid-adapted amphitropical New World taxa. Characterizing the major Dorymyrmex species groups is an important first step towards stable taxonomic definitions—which underpin active studies in behavior, chemical ecology, and physiology.

Global taxonomic revision has long been stalled by strong intra- and interspecific morphological variation, limited numbers of diagnostic characters, and dependence on infrequently collected male specimens for species description and identification. Taxonomy is further complicated by Nylanderia being one of the most frequently intercepted ant genera at ports of entry worldwide, and at least 15 globetrotting species have widespread and expanding ranges, making species-level diagnoses difficult.Three species complexes (‘bourbonica complex’, ‘fulva complex’, and ‘guatemalensis complex’) include globetrotting species. To elucidate the phylogenetic positions of these three complexes and delimit species boundaries within each, we used target enrichment of ultraconserved elements (UCEs) from 165 specimens representing 98 Nylanderia morphospecies worldwide. We also phased the UCEs, effectively doubling sample size and increasing population-level sampling. After recovering strong support for the monophyly of each complex, we extracted COI barcodes and SNPs from the UCE data and tested within-complex morphospecies hypotheses using three molecular delimitation methods (SODA, bPTP, and STACEY). This comparison revealed that most methods tended to over-split taxa, but results from STACEY were most consistent with our morphospecies hypotheses. Using these results, we recommend species boundaries that are conservative and most congruent across all methods.This work emphasizes the importance of integrative taxonomy for invasive species management, as globetrotting occurs independently across at least nine different lineages across Nylanderia.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":"1 - 15"},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45526588","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}

Stenochrus portoricensis Chamberlin, 1922, defined on a single character of the female spermathecae, is the most widespread schizomid in the New World. Numerous records in the Neotropics, from the southern United States to Brazil, throughout the Caribbean, and further afield, including the Galapagos Islands and Europe, raise the question as to whether S. portoricensis is indeed a single widespread species or a complex of multiple species with conserved morphology? The present study uses a multilocus dataset and the broadest geographical sample currently available to address the phylogeography of S. portoricensis with molecular divergence dating and ancestral area reconstruction of all currently known species of Stenochrus Chamberlin, 1922. Analyses recovered S. portoricensis as paraphyletic. Two species previously synonymized are revalidated and transferred to Stenochrus. Population structure analyses recovered the remaining samples of S. portoricensis as a single monophyletic species with low genetic divergence and comprising two subclades. Ancestral area reconstruction suggests a Mesoamerican origin for Stenochrus, which contains a widespread species, recently introduced to multiple localities. Introductions to Europe and the Caribbean occurred from a single clade in the Yucatán Peninsula, Mexico, within which genetic divergence is minimal, confirming the hypothesis of multiple independent introductions with successful colonization facilitated by parthenogenetic reproduction.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45738346","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}
