TandbergAnne.Helene.Tandberg@uib.noSaskia Brixsaskia.brix-elsig@senckenberg.deMartin SchwentnerMartin.Schwentner@nhm-wien.ac.at<p>In the vast abyssal plains northwest of Iceland, white glass sponges of the genus <em>Caulophacus </em>Schulze, 1886 were inhabited by reddish <em>Bythocaris</em> G.O. Sars, 1870 shrimps and pinkish amphipods. After in situ observations at 3700 m depth, in -1°C waters by a remotely operated vehicle, members of this assemblage were collected and preserved for molecular studies. Based on integrative taxonomic analyses, the amphipods were identified as a new species of the genus <em>Halirages </em>Boeck, 1871 – <em>Halirages spongiae </em>sp. nov. Lörz, Nack & Tandberg –, as described in detail below. Part of our integrative approach was to establish reference DNA barcodes for known species of <em>Halirages</em>. However, our investigation of material of Calliopiidae G.O. Sars, 1895 collected around Iceland and Norway revealed slight morphological discrepancies in all the described species of <em>Halirages</em>. Except for <em>Halirages fulvocinctus</em> (M. Sars, 1858)<em>,</em> none of the encountered specimens of Calliopiidae fully matched a current species description. We illuminate the morphological characteristics of nine operational taxonomic units, which also represented clades in COI and 28S. We set the Icelandic samples in the context of <em>Halirages</em> from Canada and Norway. A key to the world species of <em>Halirages</em> is provided.</p>2024-03-28T00:53:24-07:00Copyright (c) 2024 Anne-Nina Lörz, Madita Nack, Anne Helene S.

Morphologically,<em> Trimeresurus kraensis</em> sp. nov. is distinguished from other congeners by the following combination of morphological characters: a dark/bottle-green dorsum with reddish-brown or purple crossbands; pale green venter lacking dark dots; stripes present on the lateral sides of the ventrals; internasals generally in contact; one large supraocular scale on each side of the head; iris pale copper; tail brown with dark purplish-brown crossbars; dorsal scales in 21–21–15 rows; ventral scales 167 in a single male, 169–171 in females; subcaudal scales 62 in a single male, 52–54 in females, all paired. White vertebral spots present in males, located on approximately every two or four dorsal scales; dark brown spots forming discontinuous pattern present on 1–3 lateral dorsal scale rows; males with reddish-brown postocular stripe with jagged edges. The new species differs from the morphologically similar species <em>Trimeresurus venustus</em> s. str. by a notable divergence in cytochrome b mitochondrial DNA gene sequences (p = 5.9%).</p>2024-03-27T06:36:38-07:00Copyright (c) 2024 Sabira S.

Grygierthecostracans@gmail.com<p>The enigmatic ‘y-larvae’ (Thecostraca: Facetotecta) are microscopic marine planktonic crustaceans that were discovered more than a century ago, yet to this day their adults remain unknown. Despite occurring locally in large diversities, and therefore presumably being of ecological importance, only 17 species have been described globally, rendering it practically impossible to identify any y-larval specimen from any locality. The fact that species have been based on different life stages (nauplii and/or cyprids) further hampers identification. Y-larvae include many forms with planktotrophic (feeding) nauplii and even more with lecithotrophic (non-feeding) nauplii. At one coral-reef locality on the shore of Sesoko Island (Okinawa, Japan), extensive fieldwork in 2018 and 2019 confirmed an enormous taxonomic diversity of y-larvae there. Here, we present morphological diagnoses and an identification key for 34 lecithotrophic y-naupliar types (or morphospecies), which will correspond minimally to the same number of species when described. As a temporary measure, all are referred to by alphabetical parataxonomic designations, except for three that have been formally described already within the genus <em>Hansenocaris</em> Itô, 1985. To this should be added an additional 7–9 planktotrophic y-naupliar morphospecies, which are only treated briefly. Most often, y-larval taxonomy has been based on the cyprid stage, but the large morphological diversity of y-nauplii suggests that nauplii are at least as important for taxonomy. Lecithotrophic y-nauplii display a multitude of body shapes, the form-evolution of which is discussed here with reference to a recent molecular phylogeny of Facetotecta partly based on material from the same site. An indirect estimate of the relative abundances of all 34 lecithotrophic y-naupliar morphospecies is presented, based on laboratory-reared final-instar specimens. This treatment is intended as a step towards a proper taxonomy and a revised classification of Facetotecta, which will involve detailed descriptions of both nauplii and cyprids. Until such work progresses, the present overview of the y-naupliar fauna of a single Okinawan locality known to be a hotspot of y-larval diversity is offered as a baseline for further surveys of Facetotecta elsewhere in the Indo-West Pacific and beyond.</p>2024-03-25T00:00:00-07:00Copyright (c) 2024 Jørgen Olesen, Mark J.

The assumed absence of type material, the insufficient original description, and the lack of new samples from its Western Balkan type locality have stymied further clarification. The recent discovery of a single syntype shell housed at the Natural History Museum Vienna now enables the first morphological assessment via 3D X-ray and SEM imaging. Based on this image data, different characters for assessing the southernmost members of the genus are determined and a lectotype is designated. Eleven allied species from 15 Western Balkan populations are described from museum material and recent sampling efforts: <em>Z. amplioscutum</em> Jochum & Ruthensteiner sp. nov., <em>Z. biokovoense</em> Jochum & Ruthensteiner sp. nov., <em>Z. constrictum</em> Jochum & Ruthensteiner sp. nov., <em>Z. dubokidoense</em> Jochum & Ruthensteiner sp. nov., <em>Z. intermedium</em> Jochum & Ruthensteiner sp. nov., <em>Z. kolbae</em> Jochum, Inäbnit, Kneubühler & Ruthensteiner sp. nov., <em>Z. neuberti</em> Jochum & Ruthensteiner sp. nov., <em>Z. njegusiense </em>Jochum & Ruthensteiner sp. nov., <em>Z. njunjicae</em> Jochum, Schilthuizen & Ruthensteiner sp. nov., <em>Z. tortuosum</em> Jochum & Ruthensteiner sp. nov. and <em>Z. tumidum</em> Jochum, Schilthuizen & Ruthensteiner sp. nov. One species, <em>Z. kolbae</em>, is described using DNA sequence data and one species, <em>Z. simplex</em> Inäbnit, Jochum & Neubert, 2021 for which DNA sequence data is already available, is supported by morphological data presented in this study. The DNA sequence dataset (COI, 16S and H3) is included here and implemented in the most recent phylogenetic reconstruction of the genus.

We encountered nine species of which four were already known from off Mauritania. Four new species are proposed herein: <em>Granulina reginae</em> sp. nov., <em>G. ronaldi </em>sp. nov., <em>G. sandrae </em>sp. nov. and <em>G. sigridae </em>sp. nov. These four sympatric new species lack labial denticles and they probably form a phyletic clade with a common ancestor. Most hitherto known species in <em>Granulina </em>from the NE Atlantic Ocean and the Mediterranean possess labial denticles. One additional new species with denticles was left in open nomenclature because the material available was considered inadequate. Species in <em>Granulina</em> from Mauritania and Western Sahara have not been found off NW Morocco or the Canary Islands, and the species known from NW Morocco and the Canary Islands have not been found off Mauritania and Western Sahara. The southern extents of the distributions of the Mauritanian species are currently uncertain as additional sampling would be required off Senegal or further South.
