In this study, with an extensive taxon sampling of <em>Paragymnopteris</em>, we assembled 19 complete plastomes of all recognized <em>Paragymnopteris</em> species, plastomes of <em>Pellaea</em> (3 species) and <em>Argyrochosma</em> (1 species), as well as transcriptomes from <em>Paragymnopteris</em> (6 species) and <em>Argyrochosma</em> (1 species). We conducted a comprehensive and systematic phylogenomic analysis focusing on the contentious relationships among the genus of <em>Paragymnopteris</em> through 9 plastid makers, the plastomes, mitochondria, nuclear ribosomal cistron genomes, and single-copy nuclear genes. Moreover, we further combined distribution, ploidy, and morphological features to investigate the evolution of <em>Paragymnopteris</em>. The backbone of <em>Paragymnopteris</em> was resolved consistently in the nuclear and plastid phylogenies.

In this study, we utilized plastomes and single-copy nuclear genes from genome skimming sequencing to reconstruct the generic relationships and estimate the divergence time for the core Millettieae, focusing on the Asian species of <em>Millettia</em>. Our results revealed a broader circumscription of the core Millettieae with the inclusion of the Phaseoleae subtribe Ophrestiinae, consisting of 7 clades and 14 subclades within two main groups (canavanine and non-canavanine).

These patterns can be observed today through the survival of Gondwanan lineages contrasted with relatively recent colonization from south-east Asia, respectively. In general, the post-Gondwanan immigrant lineages from south-east Asia are taxa with traits that facilitate dispersal. Consequently, taxa like tarantulas (Araneae, Theraphosidae) that are largely pan-tropical but also have a low propensity for dispersal, are thought to be Gondwanan in origin. However, the Australian tarantulas are unsampled for phylogenomic studies and, as such, their classification and biogeographic origins have been long debated and are unresolved. Here we test if their current, morphology-based classification in Selenocosmiinae is accurate and assess whether the Australian tarantulas were present in Australia while it was part of Gondwana. We sample 369 tarantula specimens from across Australia, greatly expanding the geographic sampling of previous studies, to develop the first continent-wide phylogeny of the Australian tarantulas. To resolve the ‘back bone’ of the Australian tarantula phylogeny we generate 20 new transcriptomes for species of Australian tarantulas representing distinct lineages uncovered using mitochondrial sequence data and combine these new transcriptomes with published transcriptomic data. Through the recovery of ultra-conserved element (UCE) loci from transcriptomes and testing multiple data occupancy matrices, we find that the Australian clade is monophyletic and nested inside the largely Asian Selenocosmiinae. We find the Australian fauna are a relatively young radiation with a crown age of 18.8–8.3 Ma and we therefore reject the hypothesis of a Gondwanan origin for these animals and, instead, infer a recent dispersal from south-east Asia. Our findings indicate that they underwent a rapid radiation, possibly coinciding with their arrival into Australia.

Despite being named for their nursery webs, similar structures are built by some members of Ctenidae, Trechaleidae, and Oxyopidae. Pisauridae has no known morphological synapomorphies that circumscribe all members of the family, and delineation of subfamilies has been a longstanding issue. In addition, several recent molecular phylogenetic studies have called into question the monophyly of Pisauridae. Here, we infer a phylogeny of Pisauridae with nine genetic markers (12S, 16S, 18S, 28S, actin, COI, histone H3, ITS2, and NADH) combined with ultraconserved elements (UCEs) to test the monophyly of the group and determine intrafamilial relationships. Our study includes a total of 81 terminals (59 of them pisaurids). Our maximum likelihood and gene coalescence analyses strongly suggest that as currently circumscribed, the family Pisauridae is not monophyletic.

We provide a phylogenetic delimitation of the three subfamilies of Pisauridae: Halinae, Thaumasiinae, and Pisaurinae. Ten pisaurid genera are deemed <em>incertae sedis</em> in terms of their placement. In light of our hypothesized molecular phylogeny, we discuss the morphological characters and putative synapomorphies of Pisauridae and propose diagnostic characters for its subfamilies and for the family Dolomedidae, along with taxonomic notes about genera not included in our study.</div></div>","PeriodicalId":56109,"journal":{"name":"Molecular Phylogenetics and Evolution","volume":"203 ","pages":"Article 108247"},"PeriodicalIF":3.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142689695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phylogeny of Ctenidae has been examined using morphology and Sanger-based sequencing data, but these studies have been limited by taxon sampling and have often recovered low branch support for many intrafamilial phylogenetic relationships. Herein, we present the most extensive phylogenetic sampling of this family using genome-scale data, leveraging museum collections of all ctenid subfamilies from across the world. We obtained a well-resolved phylogeny of Ctenidae, with the majority of nodes showing maximal nodal support and topological congruence across different phylogenetic analyses. For the first time, we show with high support that <em>Ancylometes</em> is not within Ctenidae but is the sister lineage to all the remaining lycosoid families. Therefore, we propose Ancylometidae as a new family. We assess the phylogenetic position of Ctenidae within Lycosoidea using a variety of phylogenetic methods and tests, demonstrating that the previously proposed position of Ctenidae as the sister clade of Psechridae, based on phylotranscriptomic analyses, lacks phylogenetic support. As a new finding, this study shows that the subfamily Acantheinae, as currently delimited, is polyphyletic. Therefore, we erect the new ctenid subfamily Enoplocteninae to accommodate the Neotropical genera <em>Enoploctenus</em>, <em>Chococtenus</em>, and <em>Phymatoctenus</em>. Our phylogenomic results using UCE data resolve the position of several problematic genera (e.g., <em>Califorctenus</em> and <em>Acantheis</em>) and add support to other parts of the tree that received low support in the most recent Sanger-based phylogeny. We discuss some of the putative morphological synapomorphies of the main ctenid lineages within the phylogenetic framework provided by the molecular phylogenetic results of this study.</div></div>","PeriodicalId":56109,"journal":{"name":"Molecular Phylogenetics and Evolution","volume":"203 ","pages":"Article 108245"},"PeriodicalIF":3.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
