Our dataset consists of 6.3 kbp of one mitochondrial and seven nuclear DNA loci and was analysed using model-based phylogenetic methods, that is, maximum likelihood and Bayesian inference. Based on the recovered topology, we recognize two subfamilies, Euteliinae and Stictopterinae, and the tribes Stictopterini and Odontini. We identify apomorphic morphological character states for Euteliidae and its component subfamilies and tribes. Several genera (e.g., <i>Targalla, Paectes, Marathyssa, Eutelia</i>) were found polyphyletic and require taxonomic revision. Two new genera (<i>Niklastelia</i> Zahiri &amp; Holloway <b>gen.nov.</b> and <i>Pellinentelia</i> Holloway &amp; Zahiri <b>gen.nov.</b>) are described and a number of taxonomic changes (new combinations and new synonymies) are established. The Neotropical genus <i>Thyriodes</i>, currently included in Euteliidae, is found to be associated with Erebinae (Erebidae). The divergence time estimate for the split between the Euteliidae and Noctuidae is at 53 Ma, and the Euteliidae subfamilies Euteliinae and Stictopterinae are estimated to have diverged at 42 Ma. In Stictopterinae, the tribes Stictopterini and Odontodini split at 31 Ma, while Euteliinae began diversifying at 34 Ma. Malpighiales are inferred to have been the ancestral larval hostplant order for Euteliidae. The ancestors of Stictopterinae also appear to have been Malpighiales feeders, but then diverged to Malvales specialists (Odontodini) and Malpighiales specialists (Stictopterini) hostplants. Larvae of Stictopterini appear to be restricted primarily to Clusiaceae, apart from a few records from Dipterocarpaceae. In Euteliinae, Anacardiaceae are predominant as larval hosts. Thus, all hosts in the family are lactiferous, possibly providing some degree of pre-adaptation for exploiting Dipterocarpaceae.</p>","PeriodicalId":22126,"journal":{"name":"Systematic Entomology","volume":"48 3","pages":"445-462"},"PeriodicalIF":4.8,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/syen.12587","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50131000","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}

Over the last two decades, morphological and molecular studies have revealed widespread paraphyly and polyphyly among genera, and a comprehensive, robust phylogenetic hypothesis is needed to build a firm generic classification to support ongoing taxonomic revisions at the species level. Here, we generated a dataset that includes sequences for up to nine nuclear genes and the mitochondrial COI ‘barcode’ for a total of 1280 specimens representing 449 described and undescribed species of Euptychiina and 39 out-groups, resulting in the most complete phylogeny for the subtribe to date.

The origin and radiation of the alpine butterfly <i>Parnassius</i>, a high-altitude mountainous insect group, can be attributed to the uplift of the Qinghai-Tibet Plateau. Despite detailed phylogenetic analyses of the genus, deep phylogenetic relationships among the major subgenera remain recalcitrant. In this study, 102 individuals from 10 representative <i>Parnassius</i> species were sampled to resolve the phylogenetic relationships among subgenera based on nuclear and mitochondrial genome datasets. Gene-tree/species-tree conflicts were detected by concatenation and multispecies coalescent (MSC) approaches. We recovered a well-supported species tree, despite these conflicts, and detected considerable phylogenetic discordance among genomic regions. The main explanation for the topological discordance among subgenera was extensive incomplete lineage sorting (ILS), whereas introgression events were not prominent. The origin and explosive radiation of <i>Parnassius</i> (i.e., rapid succession of speciation events) in the late Miocene associated with environmental events on the plateau led to short internal branches, thereby increasing ILS and topological conflicts, especially among closely related subgenera. Our results also suggested that MSC approaches (SNP and AFLP Package for Phylogenetic analysis [SNAPP] and SVDquartets) are accurate and superior to the concatenation approach; in particular, SVDquartets can explicitly accommodate gene-tree/species-tree conflicts caused by high ILS and demonstrate strong robustness. Finally, we explored the phylogenomic data by testing multiple sources of phylogenomic conflict to clarify the strengths and limitations of different approaches, while considering phylogenetic signal variation in mitochondrial loci.

The higher-level classification of the family has historically been controversial due, in part, to the extreme sexual dimorphism exhibited by these insects and their morphological similarity to other wasp taxa that also have apterous females. Modern hypotheses on the internal higher classification of Mutillidae have been exclusively based on morphology and, further, they include Myrmosinae as a mutillid subfamily. In contrast, several molecular-based family-level studies of Aculeata recovered Myrmosinae as a nonmutillid taxon. To test the validity of these morphology-based classifications and the phylogenetic placement of the controversial taxon Myrmosinae, a phylogenomic study of Mutillidae was conducted using ultraconserved elements (UCEs). All currently recognized subfamilies and tribes of Mutillidae were represented in this study using 140 ingroup taxa. The maximum likelihood criterion (ML) and the maximum parsimony criterion (MP) were used to infer the phylogenetic relationships within the family and related taxa using an aligned data set of 238,764 characters; the topologies of these respective analyses were largely congruent. The modern higher classification of Mutillidae, based on morphology, is largely congruent with the phylogenomic results of this study at the subfamily level, whereas the tribal classification is poorly supported. The subfamily Myrmosinae was recovered as sister to Sapygidae in the ML analysis and sister to Sapygidae + Pompilidae in the MP analysis; it is consequently raised to the family level, Myrmosidae, &lt;b&gt;stat.nov.&lt;/b&gt; The two constituent tribes of Myrmosidae are raised to the subfamily level, Kudakrumiinae, &lt;b&gt;stat.nov.&lt;/b&gt;, and Myrmosinae, &lt;b&gt;stat.nov.&lt;/b&gt; All four recognized tribes of Mutillinae were found to be non-monophyletic; three additional mutilline clades were recovered in addition to Ctenotillini, Mutillini, Smicromyrmini, and Trogaspidiini sensu stricto.
