However, molecular phylogenetic studies of the class Copepoda remain limited, and the focus has been mainly on the major taxa, namely Calanoida, Cyclopoida, Harpacticoida and Siphonostomatoida. Consequently, a comprehensive phylogeny encompassing diverse copepod groups has yet to be established. In this study, we reconstructed the phylogeny of Copepoda using amino acid sequences of 40 orthologous genes, with particular emphasis on the previously understudied order Platycopioida. Our primary objectives were to confirm the generally recognized ancestral position of Platycopioida and to investigate subsequent phylogenetic changes in light of previous studies while incorporating additional copepod taxa. Our phylogenomic and statistical analyses revealed that Platycopioida represents the most basal lineage of Copepoda, which is consistent with previous morphological studies. In addition, we investigated the minor topological changes observed within the Podoplea clade, particularly in relation to the inclusion of additional copepod taxa and the use of more genetic information to improve the accuracy of phylogenetic inference.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":" ","pages":""},"PeriodicalIF":8.9,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149026665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we perform a new combined-evidence phylogenetic analysis. We integrate a revised and dependency-coded matrix of 54 discrete characters with 42 morphogeometric and 5 continuous characters, across a comprehensive sample of 37 taxa. This approach overcomes key logical limitations of previous discrete datasets and quantitatively captures shape variation. The analysis yields a fully resolved and well-supported topology for Toxodontidae, with Adinotherium, Proadinotherium and Nesodon forming a paraphyletic assemblage. We identify five major clades, several of which are strongly supported and formally define them based on their sister-group relationships: Xotodontinae is sister of Altiplaniinae, both are sister to a clade comprising Haplodontheriinae and Mixodontinae + Toxodontinae. Branch length decomposition shows the initial divergence and key internal nodes were dominated by discrete character change, while later radiations were driven by morphogeometric change, indicating diversification through shape reorganization. Ancestral reconstructions reveal a shift from a generalized morphotype to specialized forms with euhypsodonty, incisor hypertrophy and larger dental dimensions. This robust phylogenetic framework resolves the long-standing impasse within Toxodontidae phylogeny and provides a foundation for testing evolutionary and biogeographic hypotheses.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 5","pages":"468-491"},"PeriodicalIF":8.9,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147595959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we collected 22 samples from 18 populations representing all species of subgenus Caloscordum (Allium). Using transcriptome and whole-genome resequencing data, we generated 1755 low-copy nuclear genes and 81 plastid genes. By integrating morphological and phylogenomic evidence, we clarified the subgenus's complex evolutionary histories and speciation patterns. A total of 18 morphological characteristics were analysed, with a taxonomic framework established. Our analyses resolved robust species relationships despite detecting extensive phylogenetic discordances, which were attributed to incomplete lineage sorting (ILS) and hybridization. Specifically, our results suggest that A. inutile originated via rapid budding speciation from the widespread A. tubiflorum. This process likely coincided with mid-Pleistocene glacial–interglacial cycles and may have been reinforced by geographic isolation and ecological adaptation. In contrast, the sole tetraploid species, A. peikingense, was confirmed to be of hybrid origin, derived from A. neriniflorum and A. tubiflorum. This allopolyploidization event appears to have been facilitated by secondary contact between the parent species, which was likely associated with climatic oscillations within the 35° N–45° N arid belt. Overall, our findings elucidate the intricate speciation patterns within Caloscordum and highlight how the interplay of polyploidization, ecological isolation, and tectonic uplift-driven aridification has shaped plant diversity in East Asia.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 5","pages":"425-446"},"PeriodicalIF":8.9,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a historical lack of phylogenetic focus, the internal relationships and evolutionary history of the tribe remain poorly understood. In this study, we provide the first robust phylogenetic framework for Leistarchini by integrating molecular data from mitochondrial genomes and nuclear rDNA (88 taxa, 19 937 bp) with universal single-copy orthologs (24 taxa, 667 loci). Our results support the monophyly of Leistarchini and identify five major clades, including a newly described genus Calliemesa gen. n. Our findings further reveal that the five most species-rich genera (Nesita, Orthunga, Pleias, Ploiaria and Tinna) are either paraphyletic or polyphyletic as currently circumscribed. Molecular dating and biogeographic reconstructions suggest a Southeast Asian origin for the Leistarchini crown group during the late Palaeocene (ca. 57 Ma). Early diversification appears to have been driven by Paleogene geological and climatic shifts in Southeast Asia, while multiple intercontinental dispersals since the middle Eocene into the Afrotropics, Madagascar and the New World shaped the current global distribution. Ancestral state reconstructions indicate that the Leistarchini ancestor possessed a well-developed posterior pronotal lobe and a three-segmented protarsus. Subsequent evolutionary trajectories involved four independent transitions toward a shortened posterior pronotal lobe, and four separate reductions in protarsal segmentation.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 5","pages":"447-467"},"PeriodicalIF":8.9,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147822141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the macroevolutionary process since its deep-time origin via a total-evidence approach has been investigated only in a limited number of groups. Here we present the first total-evidence phylogenetic and biogeographic analyses of Dilaridae, a key transitional group of Neuroptera, integrating high-resolution 3D morphological reconstructions of Cretaceous stem-group taxa. We describe a new genus and four new species from the Kachin amber, that is, †Palaeonallachius fangyuani gen. et sp. nov., †Coronidilar jiaxiaoae sp. nov., †Cretodilar zhiqiae sp. nov. and †Cretodilar galaxias sp. nov., which provide valuable morphological data for phylogenetic inference. Comparative analyses using alternative sampling strategies (extant-only or total-evidence) demonstrate the advantages of integrating fossil data in phylogenetic inference, divergence-time estimation and ancestral range reconstruction. Our results support a Gondwanan origin of Dilaridae associated with the West Burma Block, followed by dispersal into Laurasia via northward-drifting Gondwanan landmasses and possible trans-Antarctic dispersal since the Jurassic. The absence of extant dilarids in Australasia is likely due to extinction.

Phylogenomic analyses based on maximum likelihood, ASTRAL, and maximum parsimony demonstrate that Acanthochitonidae, as it was traditionally defined, is paraphyletic, comprising three distinct, well-supported families.

Nuttallochitonidae is elevated to superfamily rank based on its consistent phylogenetic position and distinctive morphology. The genus Choneplax is polyphyletic, with its species distributed across three genera in two families, possibly resulting from habitat-driven convergent evolution. Ancestral state reconstructions reveal that there is no stepwise reduction in slit number but independent shifts correlating with tegmentum reduction and ecological specialization in multiple lineages. Reconstruction of historical biogeography suggests an Indo-Pacific origin for Cryptoplacoidea, with strong geographic structuring within Acanthochitona.

It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character homoplasy and phenotypic variation found across the group, resulting in vague family concepts. The present work aims to mitigate this problem by conducting the thus far most densely sampled phylogenetic study (including 58% of all known genera), combining genomic subsampling (ultraconserved elements) and marker sequencing approaches. Our study especially focused on the so-called Austral marronoids, which have not been sufficiently treated in recent revisionary works. Our results find robust evidence for a biogeographic separation of most marronoid families, which generally exhibit their highest diversity in temperate regions of both hemispheres and are poorly represented in the tropics. Based on our phylogenetic and comparative morphological study, we propose a revised classification system of the marronoid clade, comprising 18 families.
