Systematics of this family was until recently based on traits of the genital system that were shown to be uninformative, resulting in revisions of classifications at the genus and family levels. Up to six species were recognized in <jats:italic>Monachoides</jats:italic> lately, but the inclusion of three of these species was questionable. Our phylogenetic analysis and morphological examinations show that the genus includes species previously classified in two different Hygromiidae subfamilies. After transferring three Balkan species to the unrelated genus <jats:italic>Xerocampylaea</jats:italic>, <jats:italic>Monachoides</jats:italic> emerged as a group that diversified relatively northerly, at the boundary between the Balkans and Central Europe. One species, <jats:italic>Monachoides bacescui</jats:italic>, is synonymized here and a previously overlooked one is redescribed, leaving only three valid species in <jats:italic>Monachoides</jats:italic> as currently understood: <jats:italic>M</jats:italic>. <jats:italic>incarnatus</jats:italic>, <jats:italic>M</jats:italic>. <jats:italic>vicinu</jats:italic>s and <jats:italic>M</jats:italic>. <jats:italic>welebitanus</jats:italic>. These can be distinguished from other hygromiid species by their distinctive microsculpture of the shell surface, which also allows for identification of juveniles or fragmented fossil material. However, the clade comprising the three above species was found to also include the two species currently classified in <jats:italic>Perforatella</jats:italic>. As a result, the two genera are synonymized, with <jats:italic>Perforatella</jats:italic> having priority.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":"29 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140568734","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}

High‐throughput sequencing methods coupled with morphological analyses have facilitated revision of several scleractinian lineages, including the aforementioned family. In previous studies that relied on few mitochondrial and nuclear markers, the caryophylliid genera <jats:italic>Stephanocyathus</jats:italic> and <jats:italic>Vaughanella</jats:italic> were phylogenetically recovered in separate clades from the lineage that includes the type genus of the family, <jats:italic>Caryophyllia</jats:italic>, which is considered the ‘true’ Caryophylliidae. To help untangle the relationship among taxa of this family, here a new deep‐sea scleractinian family (Stephanocyathidae Vaga, Cairns &amp; Kitahara fam. nov.) is proposed based on phylogenomic reconstructions coupled with molecular features, specifically gene order, of the complete mitochondrial genome. Evolutionary reconstructions were based on both mitochondrial and nuclear ultraconserved elements (UCEs) and exon loci data sets and confirmed the divergent position of the genera <jats:italic>Stephanocyathus</jats:italic> and <jats:italic>Vaughanella</jats:italic>. The new family shows a specific gene transposition in the mitochondrial genome, not present in the ‘true’ caryophylliid lineage, but instead already observed for the species <jats:italic>Paraconotrochus antarcticus</jats:italic>, recovered as sister taxon of the here proposed new family. Although its phylogenetic position is unknown, the genus <jats:italic>Ericiocyathus</jats:italic> is also added to the new family, based on macromorphological similarities. This study represents a step forward in our understanding of deep‐sea corals relationships and provide further information (e.g., mitochondrial gene order) that will aid in future efforts of assessing the systematic of caryophylliid lineages.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":"29 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140568884","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 Mexican Plateau cenocron, with Neotropical affinities, is found in temperate and dry climates in the Nearctic region. We hypothesised that it underwent an adaptive shift in environmental niche. We tested this hypothesis using a phylogenetic comparative framework, measuring phylogenetic signal and fitting to single optima macroevolutionary models, and an Ornstein‐Uhlenbeck macroevolutionary model with multiple optima. We used phylogenetic and distributional information of the tribe Phanaeini to assess whether there exists a distinction in conservatism between the earliest (Mexican Plateau) and most recent (Typical Neotropical) cenocrons within the Mexican Transition Zone (MTZ) as this tribe stands as a classic example of the dispersal and diversification patterns of cenocrons originating in the Neotropics. We identified different shifts in environmental requirements that match the niche description of the Mexican Plateau cenocron, suggesting that it was established through multiple adaptive shifts in the Mexican Transition Zone.","PeriodicalId":49334,"journal":{"name":"Zoologica Scripta","volume":"46 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140128704","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}

Analysing their interplay in a phylogenetic framework is key to understand the historical processes that have shaped the evolution of a group. Here, we modelled the ecological niches and geographic distributions of the five species of doraditos (<jats:italic>Pseudocolopteryx</jats:italic> spp.) to study their biogeographic histories, niche evolution and speciation process in a phylogenetic framework. Our potential distribution models uncovered novel range‐wide distributional patterns and seasonal movements in the doraditos, where four species are migratory with distinct breeding and non‐breeding distributions, and one (<jats:italic>P. sclateri</jats:italic>) exhibits a complex spatiotemporal distribution indicating nomadism. Ecological niche pairwise comparisons showed that none of the doraditos have equivalent niches and that niche differences are due to species‐specific habitat preferences. Phylogenetically weighted geographical and ecological analyses showed patterns of allopatric speciation and niche lability in the evolution of doraditos. The divergence of <jats:italic>P. sclateri</jats:italic> seems tied to its tropical‐to‐temperate wetland specialization. The montane <jats:italic>P. acutipennis</jats:italic> expanded to human‐modified lowlands following speciation, highlighting the need to control for post‐speciational changes in ecological niche comparisons as done here.

The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. In this study, we assessed the diversity, relationships, and distribution of species of the <i>Prionospio</i> complex occurring in Norwegian waters. We analysed mitochondrial genomes and nuclear ribosomal DNA assembled via whole-genome shotgun sequencing, and Sanger sequenced fragments of COI and 16S rDNA. Sanger sequencing proved challenging in the group, where COI was only amplified successfully in 14% of specimens. By molecular species delimitation algorithms, our study revealed the presence of four well-supported but currently undescribed species of <i>Prionospio</i> in Norwegian waters. We observed a novel distribution pattern of polychaetes in coastal waters, where certain species demonstrated distribution ranges spanning over 7000 km. Such wide distribution parallels patterns of deep-sea <i>Prionospio</i> species, suggesting that factors beyond recent anthropogenic translocations are involved. Our analysis of 38 mitochondrial genomes and ribosomal nuclear DNA enabled us to hypothesise on the phylogenetic relationships of 14 species of the <i>Prionospio</i> complex<i>.</i> The analysis suggested that two characters previously used to designate genera: the beginning of the branchiae from chaetiger 3 and the presence of pinnules on the branchiae, might have evolved more than one time within the complex.

Furthermore, this species can be used as a model for examining Iranian Platuea's historical biogeography. We conducted a very detailed sampling of its distribution and used genetic approaches. Phylogenetic analyses were done implementing two mitochondrial (Cyt<i>b</i> and 16S) and one nuclear (C-mos) gene fragments. Combination of these results indicated that seven well-supported distinct clades exist within this species complex, i.e. Kerman clade, Esfarayen clade, Halil clade, Ardestan clade, <i>M. watsonana</i> clade, Bardaskan Clade, and Khuzestan Clade in Iran. Also, our results revealed that several distinct clades diverged due to geologic events when the Dasht-e-Kavir and the Zagros Mountains were formed. It seems that the ancestor of <i>M. watsonana</i> spread to Iranian Plateau before the formation of the Zagros Mountains. Orogenic activities of the Zagros Mountains and the formation of deserts have influenced the separation of these lineages from the Late Miocene by allopatric speciation.
