After examining recent and museum collections from Chile and Argentina, two new species of generic uncertainty were identified. A new genus of scutigerid centipede, <i>Edgethreua</i>, is therefore described with two new species, <i>E. chilensis</i> from Central Chile (type species of the genus) and <i>E. goloboffi</i> from Argentinian Patagonia. The new genus is characterised by the presence of scattered setiform bristles with short paired spines and the absence of simple spinulae and spines on all stomatotergites, the presence of a single spine-bristle in the prefemur of the second maxilla, a patch of cuticular ridges and pores surrounding the sensilla of the proximal labral portion of the epipharynx, the morphology of the sensilla of the distal patch of the hypopharynx and the morphology of the female gonopods. A phylogenetic analysis of the new species using two nuclear ribosomal RNA genes (<i>18S</i> and <i>28S</i> rRNA), two mitochondrial ribosomal RNA genes (<i>12S</i> and <i>16S</i> rRNA) and the mitochondrial protein-encoding gene cytochrome <i>c</i> oxidase subunit <i>I</i> show that the new genus does not cluster with any other described genus of scutigeromorph represented in molecular phylogenies. The data indicate that the new genus is probably sister group to a clade including the genera <i>Lassophora</i>, <i>Ballonema</i> and the subfamily Thereuoneminae, although one analysis suggests a position as sister group to Scutigerinae.</p><p>ZooBank: urn:lsid:zoobank.org:pub:A4D453F3-9031-4E21-84C7-87F16C07AD51</p>","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"52 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140577680","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}

Similarities in morphology and host associations between <i>Ivanovcestus</i> and <i>Semiorbiseptum</i> – a genus yet to be assigned to one of the families in the order Rhinebothriidea – led us to explore the possibility that <i>Semiorbiseptum</i> might also belong in the Escherbothriidae. Morphological similarities with <i>Scalithrium ivanovae</i>, <i>Scalithrium kirchneri</i> and <i>Rhinebothrium scobinae</i>, all of which also parasitise arhynchobatid skates, raised questions regarding the generic placements of these species. In addition, new collections from the skate <i>Sympterygia brevicaudata</i> revealed two new species that morphologically resemble species of <i>Ivanovcestus</i>. A combination of morphological and molecular data were used to assess the generic placement of the newly discovered species and refine our understanding of the membership of the family Escherbothriidae. Sequence data for the D1–D3 region of the <i>28S rDNA</i> gene were generated <i>de novo</i> for 14 specimens of 7 rhinebothriidean species and combined with comparable published data to represent all 6 families in the Rhinebothriidea in the analysis. The phylogenetic tree resulting from maximum likelihood analysis strongly supports the inclusion of the genus <i>Semiorbiseptum</i> in the family Escherbothriidae. Our work also suggests that the skate-hosted species previously assigned to <i>Scalithrium</i> and <i>Rhinebothrium</i> are also members of <i>Semiorbiseptum</i> and that <i>Ivanovcestus</i> is a junior synonym of <i>Semiorbiseptum</i>. Six species are transferred to <i>Semiorbiseptum</i>, bringing the total number of species in the genus to ten. The diagnosis of <i>Semiorbiseptum</i> is amended to accommodate the additional species. A second species in the previously monotypic type genus of the family, <i>Escherbothrium</i>, is described. The diagnosis of the Escherbothriidae is amended to include the new and transferred species. This study underscores the importance of integrating morphological and molecular data in bringing resolution to cestode systematics. We believe our findings provide a robust foundation for future research into the evolutionary history and host associations of cestodes within the order Rhinebothriidea and beyond. These also highlight the importance of expanding our understanding of skate-hosted cestodes.</p><p>ZooBank: urn:lsid:zoobank.org:pub:8052AFCA-5FBD-4430-95F4-0E5E368DEA3D</p>","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"18 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140578022","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}

Knowledge of these groups is fragmentary and in many instances, no information is available beyond original descriptions. We assess the monophyly, phylogenetic placement and species-level diversity of the Ulopini genus <i>Austrolopa</i>.

However, recent studies have shown that these diagnostic features are ontogenetically variable and this has resulted in taxonomic confusion among <i>Torix</i> species endemic to the Japanese Archipelago. In this study, we revisit the taxonomic accounts of <i>T. orientalis</i> (Oka, 1925) and <i>T. tagoi</i> (Oka, 1925), in addition to that of the recently redescribed <i>T. tukubana</i> (Oka, 1935) to clarify the diagnostic characteristics for each of the three species.

We study the placement of <i>Paraplectanoides</i> and the classification of the family Araneidae by combining ultraconserved elements with Sanger markers. We also added Sanger sequences of the Australian araneid genus <i>Venomius</i> to the molecular dataset of Scharff <i>et al</i>. (2020) to explore the phylogenetic placement and implications for classification of the family. We evaluate a recent proposal on the classification of the family Araneidae by Kuntner <i>et al.</i> (2023) in which a new family is erected for <i>P. crassipes</i>. <i>Paraplectanoides</i> is monotypic. Examination of the type material shows that <i>Paraplectanoides kochi</i> O. Pickard-Cambridge, 1877 is misplaced in the genus and the name is a senior synonym of the araneid <i>Isoxya penizoides</i> Simon, 1887 (<b>new synonymy</b>) that results in the <b>new combination</b> <i>Isoxya kochi</i> (O. Pickard-Cambridge, 1877). The classification of Araneidae is revised and the following nomenclatural acts are introduced: Paraplectanoididae Kuntner, Coddington, Agnarsson and Bond, 2023 is a junior synonym of Araneidae Clerck, 1757 <b>new synonymy</b>; phonognathines and nephilines are subfamilies of Araneidae (Subfamily Phonognathinae Simon, 1894 <b>rank resurrected</b>; and Subfamily Nephilinae Simon, 1894 <b>rank resurrected</b>).

The placement of the oarcine araneids and <i>Venomius</i> renders the family Araneidae non-monophyletic if this were to be circumscribed as in Kuntner <i>et al</i>. (2023). In light of the paucity of data that the latter study presents, and in absence of a robust, stable and more densely sampled phylogenetic analysis of Araneidae, the changes and definitions introduced by that classification are premature and could lead to a large number of new families for what once were araneid species if the maximum-crown-clade family definitions were to be used.
