Here we report our latest phylogenetic analysis of tinamous, built on previous comprehensive studies, presently including all 46 currently recognized species. Our goal was to apply all the valid available supraspecific names to the clades recovered, creating new ones as needed. We recovered the traditional major subclades, forest-dwelling vs. open-areas tinamous, with all three currently recognized genera in the former matching the chief groupings, and with two taxa in the latter that do not fit the current classification as per the phylogenetic results. Our analysis of the taxonomic history of tinamid taxa revealed complications chiefly owing to the convoluted history of certain key names, particularly <i>Tinamus</i>. We disentangled the perceived misapplication of <i>Tinamus</i> to various tinamid taxa, concluding that <i>Tinamus</i> Hermann, 1783 is valid and not <i>Tinamus</i> Latham, 1790, with type species <i>soui</i> Hermann, 1783, currently placed in <i>Crypturellus</i>. As a consequence, while the phylogenetic signal is clear, a major taxonomic rearrangement is needed in the forest-dwelling tinamous reassigning species of small forest tinamous (currently in <i>Crypturellus</i>) according to priority to <i>Tinamus</i> Hermann, and former invalid <i>Tinamus</i> Latham to <i>Pezus</i> Spix, 1825. In the open-areas tinamous (Tinamotidinae), we recognize two tribes and the phylogeny also indicated the need for a new genus to be applied to <i>cinerascens</i>, formerly in <i>Nothoprocta</i>; and the synonymy of <i>Taoniscus</i>, as the single species <i>nanus</i> was recovered nested in <i>Nothura</i>.

Here, we review the phylogenetic relationships of proteocephalid tapeworms using publicly available (671) and newly generated (91) nucleotide sequences of the nuclear RNA28S and the mitochondrial MT-CO1 for 537 terminals. The main tree search was carried out under the parsimony optimality criterion, analysing different gene alignments simultaneously. Interestingly, we were not able to recover monophyly of the Proteocephalidae. Additionally, it was difficult to reconcile the tree with host and biogeographical data using traditional character optimization strategies in two dimensions. Therefore, we investigated if host and biogeographical data can be correlated with the parasite clades in a multidimensional space–thus considering multiple layers of information simultaneously. To that end, we used random forests (a class of machine learning models) to test the predictive potential of combined (not individual) host and biogeographical data in the context of the proteocephalid tree. Our resulting models can correctly place 88.85% (on average) of the terminals into eight representative clades. Moreover, we interactively increased the levels of clade perturbation probability and confirmed the expectation that model accuracy negatively correlates with the degree of clade perturbation. Our results show that host and biogeographical data can accurately predict proteocephalid clades in multidimensional space, even though they are difficult to optimize in the parasite tree. These results agree with the assumption that the evolution of proteocephalids is not independent of host and biogeography, and both may provide external support for our tree.</p>","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"41 3","pages":"264-282"},"PeriodicalIF":3.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cla.12610","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568738","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}

Much of the neglect is due to the fact that conventional taxonomic methods struggle with handling thousands of specimens belonging to hundreds of species. We thus here propose a new strategy that we call “dark taxonomy”. It addresses (i) taxonomic impediments, (ii) the lack of biodiversity baselines and (iii) the low impact of revisionary research. Taxonomic impediments are reduced by carrying out revisions at small geographic scales to keep the number of specimens low. The risk of taxonomic error is reduced by delimiting species based on two types of data. We furthermore show that dark taxonomy can yield important biodiversity baseline data by using samples obtained with biomonitoring traps. Lastly, we argue that the impact of revisionary research can be improved by publishing two papers addressing different readerships. The principles of dark taxonomy are illustrated by our taxonomic treatment of Singapore's fungus gnats (Mycetophilidae) based only on Malaise trap samples. We show that a first batch of specimens (<i>N</i> = 1454) contains 120 species, of which 115 are new to science, thus reducing taxonomic impediments by increasing the number of described Oriental species by 25%. Species delimitation started with using DNA barcodes to estimate the number of Molecular Operational Taxonomic Units (MOTUs) before “LIT” (Large-scale Integrative Taxonomy) was used to obtain the species boundaries for the 120 species by integrating morphological and molecular data. To test the taxonomic completeness of the revision, we next analysed a second batch of 1493 specimens and found that &gt;97% belonged to the 120 species delimited based on the first batch. Indeed, the second batch only contained 18 new and rare MOTUs, i.e. our study suggests that a single revision can simultaneously yield the names for all important species and relevant biodiversity baseline data.

This study evaluates the accuracy of phylogenetic reconstructions from simulated matrices of continuous characters evolving under alternative evolutionary processes and analysed by parsimony. We sampled 100 empirical trees to simulate 9000 matrices, each containing between 25 and 50 taxa, and 50 and 150 continuous characters evolving under three evolutionary processes: Brownian motion, Ornstein–Uhlenbeck and early burst with variable parametrizations. Our cladogram comparisons revealed that continuous character matrices, when properly coded and analysed by parsimony in TNT, carry phylogenetic signals from which species relationships can be inferred, regardless of the evolutionary models and parameterization schemes. Interestingly, implementing equal weighting or implied weighting with varying penalization strengths against homoplasies did not affect cladogram reconstructions based on continuous characters. Finally, the accuracy of continuous characters in resolving species relationships is skewed towards apical nodes of the recovered trees.

Although several analytical approaches have been applied to infer well-resolved phylogenetic hypotheses—even methods that are arguably conceived to be better at dealing with data conflict and uncertainty, many taxa have not been assigned to specific taxonomic categories. Here, we evaluate the phylogenetic affinities in Osmundales by reanalysing a dataset comprising an extensive taxon sampling of fossil Osmundalean rhizomes. The impact of both character dependence and weighting characters against homoplasy on the inferred topologies is also evaluated. Our analyses cast doubts on the monophyly of Osmundaceae and Guaireaceae. Subfamily Itopsidemoideae was rendered monophyletic when inferences were conducted by considering character dependence and downweighting characters. The subfamily Osmundoideae was retrieved monophyletic only under one concavity value and using character dependence while the remaining subfamilies included fossils with uncertain affinities within Osmundales. The position of <i>Osmundacaulis</i>, for instance, was recovered as a sister taxon to guaireoid fossils. To recover the monophyly of the categories below the subfamily level, incorporating character dependence and/or weighting against homoplasy was necessary. Consistent with previous studies, multiple taxa were unstable, leaving their phylogenetic affinities unclear. Our analyses underline the impact of accounting for both character dependence and weighting against homoplasy, especially when considering the contribution of missing data to observed homoplasy.
