Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships. Our study seeks to enhance the resolution of Macrodasyida's internal phylogeny through expanded taxonomic and molecular sampling. We obtained 63 new sequences from 21 Macrodasyidan species, integrating them with published data. Our dataset includes representatives from nine Macrodasyida families and 21 genera, alongside two chaetonotidans. We analysed the concatenated sequences of three genes (18S, 28S rRNA, COI mtDNA) from 51 terminals using Maximum Parsimony, Maximum Likelihood and Bayesian Inference. Our findings confirm the polyphyly of Cephalodasyidae. Dolichodasys and Paradasys cluster with Redudasyidae, while Cephalodasys and Mesodasys form unrelated lineages. Cephalodasys mahoae is nested within Paradasys rather than Cephalodasys, suggesting an original misidentification. The phylogenetic placement of Pleurodasys remains uncertain. Macrodasyidae is non-monophyletic, with Urodasys forming an independent lineage. The first molecular data ever obtained for Dendrodasys hint that the family Dactylopodolidae is likely polyphyletic as well. We propose an updated classification of Macrodasyida, introducing Mesodasyidae fam. nov., Urodasyidae fam. nov. and Paraurodasys gen. nov. Furthermore, we reassign Dolichodasys and Paradasys to Redudasyidae and Cephalodasys mahoe to Paradasys.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 1","pages":"25-45"},"PeriodicalIF":6.2,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12789844/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145764544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared point-based occurrence records and polygonal range maps for 160 species of the lizard genus Liolaemus, assessing their influence on the identification of areas of endemism across three spatial scales using endemicity analysis. Our results show that range maps consistently overestimate distributions, often identifying broad endemic areas with low species overlap—patterns likely inflated by commission errors. In contrast, occurrence data yield fewer but more localized and compositionally distinct areas of endemism, especially at finer spatial scales, capturing spatial discontinuities and narrow-range endemism more effectively. Occurrence data also proved to be more sensitive to spatial scale, revealing fine-grained biogeographic patterns often missed by range maps, particularly in mountainous or environmentally heterogeneous regions. Despite potential biases from uneven sampling, occurrence data provide a more ecologically meaningful representation of endemism, especially for habitat specialists or narrowly distributed species. These findings highlight that data choice significantly affects the detection of endemism, with direct implications for biodiversity assessments and conservation planning. Researchers should carefully consider data sources in light of their study taxa's ecological and geographic traits to ensure robust and scale-appropriate analyses.\u0000 </div>","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 1","pages":"95-107"},"PeriodicalIF":6.2,"publicationDate":"2025-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145472117","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}

The global distribution of coastal Cafius rove beetles, combined with the endemic distribution patterns observed in its subclades, suggests repeated colonization of new regions via ocean surface currents, followed by local diversification and speciation. We reached these conclusions by reconstructing the Cafius phylogeny and a time-calibrated Cafius phylogeny, then conducting a spatio-temporal biogeographic analysis. Our study is based on sequences from 10 genetic loci, including six nuclear and four mitochondrial genes (6891 bp). Our findings support the monophyly of Cafius, with an estimated origin in the early Miocene (17.91 Ma) along the coasts of Europe and Australia. From this origin, transoceanic dispersal events led to the colonization of the coasts. These patterns suggest that ancestral Cafius lineages initially migrated to continental coastlines, with subsequent vicariance and in situ speciation. The directionality of these colonization events closely aligns with global ocean surface current patterns and the geological and climatic history of the regions involved. Biological adaptations likely facilitated their survival and subsequent diversification in coastal habitats worldwide.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"42 1","pages":"79-94"},"PeriodicalIF":6.2,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12789850/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145439774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a comprehensive phylogenetic total-evidence analysis of Rhinocerotidae to date, integrating morphological, molecular, fossil and paleoclimatic data within maximum parsimony, maximum likelihood, Bayesian and time-calibrated frameworks. A matrix of 106 taxa and 534 morphological characters, including 11 newly defined ones, was assembled through systematic revision of previously ambiguous characters. In contrast to earlier studies, a fossil-based outgroup was selected in place of extant Tapirus to improve character polarity and reduce topological artefacts associated with distant outgroup choice. The resulting cladograms resolve longstanding conflicts in rhinocerotid systematics and identify many supported clades. Analyses of the studied clades revealed an association between lineage diversification and climatic thresholds, which appear to have mediated ecological turnover and the differential persistence of traits. The application of an integrative total-evidence approach illustrates the role of climatic and ecological filters in shaping the evolutionary trajectories of megafaunal lineages and contributes to broader methodological discussions in phylogenetics.

In this article, we redescribe the single specimen of N. edentata, complementing the examination with micro-CT scan reconstructions, and expanding its original description. This results in a combination of character states unique to Bufonidae, allowing us to confidently assign N. edentata to this family. Then, we performed a total evidence phylogenetic analysis, including molecular and osteological data, to evaluate the phylogenetic relationships of N. edentata within Bufonidae. This species was recovered in a strongly supported clade with the extant genus Nannophryne; thus, Neoprocoela is considered a junior synonym of this genus, retaining edentata as a valid species. Finally, considering the geographic and stratigraphic provenance of the fossil remains, we discuss its value as evidence of the early evolution of South American toads and as an absolute-age calibration point, something relatively unusual for neobatrachian fossil species of that age.","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"41 6","pages":"600-623"},"PeriodicalIF":6.2,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145349840","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}

Plastid genomes and LCN genes, assembled from 66 samples, were used to investigate the phylogenetic structure, reticulate evolution and divergence times among the species of this subtribe. Firstly, phylogenetic analysis revealed that Boeica is polyphyletic and identified a new genus, Crassicaulis, which forms a sister group to the remaining genera within the subtribe. Secondly, complex cytonuclear conflicts and gene tree incongruence at genus-level nodes were identified. Multiple lines of evidence revealed two reticulate evolutionary events within this lineage, suggesting that Boeica porosa and B. stolonifera, as well as Boeica enpingensis, underwent hybridization during their speciation processes. Finally, divergence time estimation revealed that most genera emerged between 17 and 12 Ma.
