In this study, the biology of this species is reported as living in bamboo (Poaceae: Bambusoideae), in close proximity with a highly similar ant species, <i>Polyrhachis dives</i> (Hymenoptera: Formicidae). Further, the phylogenetic position and the origin time of this stink bug species were inferred in the context of Pentatomoidea. The dated phylogeny indicates that <i>Pentamyrmex spinosus</i> is the sister group of Phyllocephalinae, a specialized grass-feeding subfamily in Pentatomidae, and diverged about 42.7 Ma (52.6–33.2 Ma), roughly synchronous with the radiation of the crown group of <i>Polyrhachis</i> ants (42.0–33.0 Ma) and slightly after the early radiation of bamboos (66.9–24.9 Ma).

In the oecleinian lineage, the Oecleini are paraphyletic, including the Bothriocerini.

The Andini tribe appears paraphyletic, including the Brixiini, and the position of the Gelastocephalini is yet to be confirmed.

This tribe is widely distributed, notably throughout the tropics of Africa, Southeast Asia and the Americas, making it a fascinating model in evolutionary biology. However, despite accounting for 25% of the global swallowtail butterfly diversity, Leptocircini have been surprisingly neglected in phylogenetic analyses. This has left unanswered questions about their taxonomy and systematics. Here, we present a new taxonomic working list for Leptocircini, featuring 162 valid species. Using a combination of long and short reads data, we produced five new reference genomes, and we generated highly covered and scaffolded whole genomes for 148 individuals to infer densely sampled phylogenetic hypotheses. Based on mitochondrial or thousands of nuclear genes and multiple phylogenetic approaches, a robust phylogenomic tree is recovered, representing approximately 90% of the known species, which allowed examination of several key phylogenetic hypotheses. We found the monotypic genus <i>Protographium</i> Munroe to be sister of genus <i>Graphium</i> Scopoli.

We explore this by focusing on Onciderini (Coleoptera: Cerambycidae: Lamiinae), a tribe of longhorn beetles commonly referred to as twig girdlers because the females of some species girdle live trees to deposit their eggs. We reconstructed the first time-calibrated phylogeny of the Onciderini, based on three genetic markers (cytochrome <i>c</i> oxidase subunit 1 ‘<i>cox1’</i>, Wingless ‘<i>Wg</i>’ and carbamoyl-phosphate synthase domain of the <i>CAD</i> locus ‘<i>CPS’</i>), and used morphometric data, employing multiple models of trait evolution and phylogenetic regressions, to assess whether girdling behaviour predicts head size or head size sexual dimorphism. Our results indicate that onciderines originated c. 49 million years ago ‘Ma’ (95% highest posterior densities ‘HPD’: 44.1–54.57 Ma) and consist of two major lineages, which we formalize as subtribes Hypsiomatina and Onciderina. Additionally, our analyses revealed several taxonomic inconsistencies within the tribe, which we rectify by proposing new synonymies, including <i>Jamesia</i> Jekel as a synonym of <i>Hypselomus</i> Perty, <i>Cipriscola</i> Dillon &amp; Dillon of <i>Hypsioma</i> Audinet-Serville and <i>Psyllotoxus</i> Thomson and <i>Taricanus</i> Thomson as a synonym of <i>Oncideres</i> Lacordaire, and a new combination for <i>Periergates kenjii</i> Nearns &amp; Swift as <i>Oncideres kenjii</i> (Nearns &amp; Swift) <b>comb. nov</b>. Using this new phylogenetic framework, we identified five independent unidirectional origins of girdling behaviour within the tribe. Overall, our results suggest that girdling influences head size evolution in Onciderini, as it is associated with an increase in both male and female head size of girdler species. Despite this, girdling and non-girdling lineages do not consistently differ in head size sexual dimorphism. This study refines the classification of Onciderini and marks a significant step in understanding the evolutionary dynamics shaping the diversity of twig-girdler beetles, a group with notable ecological and economic importance.</p>","PeriodicalId":22126,"journal":{"name":"Systematic Entomology","volume":"50 2","pages":"369-386"},"PeriodicalIF":4.7,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/syen.12660","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such group is the ant genus <i>Dorymyrmex</i>, which specializes in arid habitats throughout the Americas. To evaluate when and how <i>Dorymyrmex</i> acquired its present-day distribution, I sequenced partial genomes of 167 <i>Dorymyrmex</i> representing 69 species by targeting ultraconserved elements (UCEs).

The <i>D. pyramicus</i> group likely dispersed from South America to North America only once, via Central America. Like many Hymenoptera, this dispersal occurred before the traditional closure date of the Isthmus of Panama, corroborating and extending the results of previous studies.
