https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2633
<p>The genus <em>Lissocnemis</em> Kohl, 1907 of the subfamily Ctenocerinae is recorded from Korea for the first time. The diagnosis and characteristics of the genus, description of a new species, <em>L. koreana</em> Kim & Shimizu sp. nov. and redescription of another species, <em>L. brevipennis</em> hitherto known from Southeast Asia and Japan, are presented. The biogeographical distribution of the genus is discussed. <em>Cryptosalius</em> Turner, 1917 (type species: <em>Pseudagenia rava </em>Bingham, 1896; in part) and <em>Dinagenia </em>Banks, 1934 (type species: <em>D. apollo</em> Banks, 1934) are synonymized with <em>Lissocnemis</em> and the following new combinations are made: <em>Lissocnemis tonkinensis</em> (Turner, 1920) comb. nov. (= <em>Cryptosalius tonkinensis</em> Turner, 1920); <em>Lissocnemis apollo</em> (Banks, 1934) comb. nov. (= <em>Dinagenia apollo</em> Banks, 1934); and <em>Lissocnemis satyrus </em>(Banks, 1938) comb. nov. (= <em>Dinagenia satyrus</em> Banks, 1938). Lastly, <em>L. satyrus</em> (Banks, 1938) and <em>L. nigricoxis</em> Haupt, 1941 are rendered to be junior synonyms of <em>L. apollo</em> (Banks, 1934) comb. nov.</p>Jeong-Kyu KimAkira ShimizuJames P.

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2631
<p>Due to the fragility of the ophiuroid (brittle star) skeleton, the bulk of the group’s fossil record consists of dissociated ossicles preserved as microfossils. In spite of their great potential as basis for taxonomic and phylogenetic studies, however, ophiuroid ossicles from the Paleozoic have received very little attention so far. Here, we provide an exhaustive taxonomic assessment of such fossils retrieved from sieving residues from the Silurian of Gotland, Sweden. This material was used in a previous study to describe two key taxa that allowed constraining the origin of the extant ophiuroid clade. The remaining taxa belonging to that same lineage are described in the present paper. The evidence at hand suggests that the stem of the extant ophiuroid clade was formed by two genera, <em>Ophiopetagno</em> and <em>Ophiolofsson </em>gen. nov., including six and five species, respectively, and spanning at least the upper Llandovery through upper Ludlow. We conclude that <em>Ophiopetagno</em> and <em>Ophiolofsson</em> represent sister genera that coexisted through most of the Silurian in the shallow tropical seas of Gotland. They underwent repeated body size reductions in correlation with environmental perturbations, with <em>Ophiopetagno paicei </em>eventually giving rise to <em>Muldaster haakei</em>; the first member of the living Ophiuroidea. Herein, we also introduce two new clades, Ankhurida clade nov. and Ophiovalida clade nov., and the following eight new species: <em>Ophiolofsson joelmciveri </em>gen. et sp. nov.,<em> O. obituary </em>gen. et sp. nov., <em>O. immolation </em>gen. et sp. nov., <em>O. archspire </em>gen. et sp. nov., <em>O. hendersonorum </em>gen. et sp. nov., <em>Ophiopetagno bonzo </em>sp. nov., <em>O. kansas </em>sp. nov., <em>O. doro </em>sp. nov.; and two probably new species in open nomenclature: <em>Ophiopetagno</em> sp. 1, and <em>Ophiopetagno</em> sp. 2.</p>Ben ThuyMats E.

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2629
<p>Among the 44 genera of predatory stink bugs (Asopinae) described for the Old World, there is a notable lack of recent studies. In this research, we aim to fill this gap by investigating the taxonomic history and morphology of species of <em>Cantheconidea</em>. As results, we present the redescription of the genus and validate three species: <em>C. humeralis</em>, <em>C. javana </em>and <em>C. mitis </em>comb. nov. A lectotype for <em>C. mitis</em> is designated and comments on the type material are given. Additionally, we transfer four species from <em>Cantheconidea</em> to the genus <em>Eocanthecona</em>: <em>E. acuta </em>comb. nov., <em>E. variabilis </em>comb. nov., <em>E. gaugleri</em> comb. nov. and <em>E. insularis </em>comb. nov. To accommodate the unique characteristics of <em>Cantheconidea cyanacantha</em>, we describe a new genus, <em>Cantheconesia</em> Brugnera & Roca-Cusachs gen. nov., and transfer the species, resulting in <em>Cantheconesia</em> <em>cyanacantha</em> gen. et comb. nov. Our study provides detailed redescriptions of species and accompanying images to support taxonomic decisions and presents new distribution records.</p>Ricardo BrugneraJocelia GraziaAndrew MaynardMarcos Roca-Cusachs

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2625
<p><em>Ophioderma teres </em>(Lyman, 1860), an ophiuroid previously believed to have a wide distribution in the eastern Pacific, has been found to have an unclear taxonomic identity. While considered a well-known species, recent studies have revealed that <em>O. teres </em>lacks a holotype and has vague boundaries with its congeners <em>Ophioderma teres unicolor </em>H.L. Clark, 1940 and <em>Ophioderma sodipallaresi </em>Caso, 1986, as well as with two additional new morphotypes detected in Mexico and Nicaragua, causing continuous misidentifications. This study utilized an integrative taxonomy approach based on morphologic, morphometric, and molecular evidence to clarify the taxonomic status of <em>O. teres</em>, <em>O. sodipallaresi</em>, <em>O. teres unicolor</em>, and the two new morphotypes. Data integration led to the following results: 1) the neotype designation and redescription of <em>O. teres</em>; 2) the proposal of <em>O. sodipallaresi </em>as a junior synonym of <em>O. teres</em>; 3) the status change of <em>O. unicolor </em>stat. nov. from subspecies to species, and 4) the description of the morphotypes as the new species <em>Ophioderma aija </em>sp. nov. and <em>Ophioderma bichi </em>sp. nov. An identification key to the eastern Pacific species of <em>Ophioderma </em>was also developed. This work contributes to the knowledge of <em>Ophioderma</em> in the region, increasing the number of described species and providing resources for their accurate identification.</p>Karla J.

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2621
<p>Scalibregmatidae Malmgren, 1867 is a family of annelids, with only few taxa reported from Brazil. In this work, we describe two new species of<em> Asclerocheilus </em>Ashworth, 1901. The new species <em>A. geiseae</em> sp. nov. and <em>A. blakei</em> sp. nov. were collected during scientific expeditions to the Espírito Santo and Campos sedementary basins. These expeditions were coordinated by PETROBRAS/CENPES. The species <em>A. geiseae </em>sp. nov. is unique among its congeners by the presence of acicular spines with rounded and curved tips in two rows. The second species, <em>A. blakei </em>sp. nov., differs from its congeners by the combination of the presence of a trapezoidal prostomium, acicular spines on chaetigers 1–3, lyrate chaetae from chaetiger 3 on notopodia and 2 on neuropodia. Moreover, we report the species <em>A. tropicus </em>Blake, 1981 from the localities sampled on this study. We also provide an identification key to all species of <em>Asclerocheilus </em>of the world.</p>Samuel Lucas Da Silva Delgado MendesPaulo Cesar De PaivaAlexandra E. Rizzo

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2611
<p>The monophyly of Theraphosinae is supported by both morphological and molecular phylogenies. However, intergeneric relationships often show polytomies and branches with low support. A previous phylogenetic study proposed an intergeneric relationship for the subfamily based on molecular data and divided it into three tribes: Grammostolini, Hapalopini and Theraphosini. However, not all genera of Theraphosinae were sampled, and some relationships were inferred based on morphological similarities. Regarding the Hapalopini from Brazil, the relationships of some genera are still uncertain, such as <em>Kochiana</em>, <em>Catanduba</em>, and <em>Munduruku</em>. In this paper, we describe four new species of Hapalopini from Brazil: <em>Cyriocosmus paresi</em> sp. nov., <em>Hapalopus</em> <em>akroa</em> sp. nov., <em>H.</em> <em>guidonae</em> sp. nov., and<em> K. fukushimae</em> sp. nov. In addition, we propose an updated diagnosis for these three genera and for the species <em>K. brunnipes</em> and <em>M. bicoloratum</em>.</p>Wolf MoellerArthur Galleti-LimaJosé Paulo Leite Guadanucci

https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2619
<p>In this study, we describe two new species of <em>Mesobiotus</em> based on morphological data collected through light and scanning electron microscopy. Descriptions include DNA sequences of four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). <em>Mesobiotus</em> <em>efa</em> sp. nov. was discovered in North-West Russia and belongs to the group of species with smooth cuticle, <em>harmsworthi</em>-type OCA, typical <em>Mesobiotus</em> claws IV with unindented lunules, and egg chorion with reticulated processes in form of ‘sharp wide cones’ or ‘cones with long slender endings’, egg process bases with well-developed crone of dark thickenings without finger-like projections, and egg shell surface between the processes with ridges without reticulation, areolation or semi-areolation. It can be distinguished from all know species of this group by a unique combination of morphological and morphometric characters. <em>Mesobiotus vulpinus</em> sp. nov. was found in the Russian Far East, and is similar to <em>Mesobiotus mauccii</em> by having an egg chorion with polygonal relief. The new species can be distinguished from <em>M. mauccii</em> by having a narrower buccal tube, by details of oral cavity armature, and by longer egg chorion processes. Furthermore, we provide results of the phylogenetic analyses of the genus <em>Mesobiotus</em> conducted in this study.</p>Denis V. TumanovEvgenia D. AndrosovaMarina D. GavrilenkoAidar A. Kalimullin
