Scale-worms (Annelida, Polychaeta) collected in the “Fauna II, III, IV” Cruises (“Fauna Ibérica” Project) and a check-list of known species recorded from the Iberian Peninsula. Graellsia, 67(2): 187-197 (in Spanish). The present paper includes a check-list of the 42 species of scale-worm polychaetes (families Aphroditidae, Acoetidae, Polynoidae, Pholoidae and Sigalionidae) collected during the “Fauna Ibérica II, III and IV” cruises, as well as the data on the corresponding sampling stations. Three new records for the Iberian Peninsula are reported: Acanthicolepis zibrowii Barnich & Fiege, 2010; Harmothoe aequespina (Langerhans, 1884) and Neolagisca jeffreysi (McIntosh, 1876). An updated check-list of the 65 scale worm species known for the Iberian Peninsula is also presented.

Original specimens and type localities of early described polychaete species (Annelida) from Norway, with particular attention to species described by O.F. Müller and M. Sars. Memoirs of Museum Victoria 71: 217–236. Early descriptions of species from Norwegian waters are reviewed, with a focus on the basic requirements for re- assessing their characteristics, in particular, by clarifying the status of the original material and locating sampling sites. A large number of polychaete species from the North Atlantic were described in the early period of zoological studies in the 18th and 19th centuries.

The family Polynoidae includes a group of scale worms which is abundant in several marine environments, and many members are associated with other invertebrates. The genus Harmothoe is one of the largest in number of species within the polynoids, with more than 150 described species. We summarize in a checklist information relative to 23 nominal species of Harmothoe from South America, with valid names, synonyms and original citations, discuss possible taxonomic problems, and provide illustrations of specimens from the northeastern coast of Brazil. Redescriptions of two species based on new specimens collected along the littoral of the State of Pernambuco, northeastern Brazil, are included. Harmotthoe fuscapinae and Harmothoe lanceocirrata are reported for the first time for Brazilian waters. Key words: Scale worms, polynoids; South Atlantic, new records.

Thirty-six species belonging to seven families – Acoetidae, Pholoidae, Polynoidae, Sigalionidae, Deep-sea Glyceridae, Goniadidae and Phyllodocidae, were identified. Amended descriptions and/or new illustra- Iberian margin tions are given for the species Allmaniella setubalensis, Anotochaetonoe michelbhaudi, Lepidasthenia Barcoding brunnea and Polynoe sp. Relevant taxonomical notes are provided for other seventeen species. Allmaniella setubalensis, Anotochaetonoe michelbhaudi, Harmothoe evei, Eumida longicirrata and Glycera noelae, pre- viously known only from their type localities were found in different deep-water places of the studied areas and constitute new records for the Iberian margin. The geographic distributions and the bathy- metric range of thirteen and fifteen species, respectively, are extended. The morphology-based biodi- versity inventory was complemented with DNA sequences of the mitochondrial barcode region (COI barcodes) providing a molecular tag for future reference.

  • Zoosymposia 2: Polynoidae (Annelida
    Zoosymposia 2: 149–164 (2009) ISSN 1178-9905 (print edition) www.mapress.com/zoosymposia/ ZOOSYMPOSIA Copyright © 2009 · Magnolia Press ISSN 1178-9913 (online edition) Polynoidae (Annelida: Polychaeta) associated with cold-water coral reefs of the northeast Atlantic and the Mediterranean Sea DIETER FIEGE1 & RUTH BARNICH Forschungsinstitut und Naturmuseum Senckenberg, Senckenberganlage 25, D-60325 Frankfurt/Main, Germany. E-mail: [email protected]; [email protected] 1Corresponding author Abstract An overview of polynoid scale worms known to occur on cold-water coral reefs of the northeast Atlantic and the Mediterranean Sea is given, including a key for identification of species. Harmothoe oculinarum (Storm, 1879), H. vesiculosa Ditlevsen, 1917, and Leucia violacea (Storm, 1879) comb. nov. are redescribed. A lectotype is designated for H. vesiculosa and the generic status of Leucia violacea (Storm, 1879) comb. nov. and Neolagisca jeffreysi (McIntosh, 1876) comb. nov. are changed. The biogeography of the species is discussed. Key words: taxonomy, biogeography, Acanthicolepis, Harmothoe, Leucia, Neolagisca Introduction Cold-water coral reefs have long been known to local fishermen as productive fishing grounds especially in the Northeast (NE) Atlantic. Increasing exploitation of deep-water resources in recent years has raised awareness and subsequently shown that the extent and distribution of these reefs is apparently much wider than anticipated. They occur mainly in areas of enhanced primary productivity and water flow on the continental shelf edge, the continental slopes, and seamounts (Roberts 2005). Cold-water coral species, e.g., Lophelia pertusa (Linnaeus, 1758), a key structural species in the NE Atlantic, form a three-dimensional skeletal framework simultaneously providing niches for other species and hard substrate for the settlement of a wide variety of suspension feeding invertebrates (Rogers 1999).

  • Deep-Sea Life Issue 16, January 2021 Cruise News Sedimentation Effects Survey Series (ROBES III) Completed
    Deep-Sea Life Issue 16, January 2021 Despite the calamity caused by the global pandemic, we are pleased to report that our deep ocean continues to be investigated at an impressive rate. Deep-Sea Life 16 is another bumper issue, brimming with newly published research, project news, cruise news, scientist profiles and so on. Even though DOSI produce a weekly Deep-Sea Round Up newsletter and DOSI and DSBS are active on social media, there’s still plenty of breaking news for Deep- Sea Life! Firstly a quick update on the status of INDEEP. As most of you are aware, INDEEP was a legacy programme of the Census of Marine Life (2000-2010) and was established to address knowledge gaps in deep-sea ecology. Among other things, the INDEEP project played central role in the creation of the Deep-Ocean Stewardship Initiative and funded initial DOSI activities. In 2018, the DOSI Decade of Ocean Science working group was established with a view to identifying key priorities for deep-ocean science to support sustainable development and to ensure deep- ocean ecological studies were included in the UN Decade plans via truly global collaborative science. This has resulted in an exciting new initiative called “Challenger 150”. You are all invited to learn more about this during a webinar on 9th Feb (see p. 22 ). INDEEP has passed on the baton and has now officially closed its doors.Eva and I want to sincerely thank all those that led INDEEP with us and engaged in any of the many INDEEP actions. It was a productive programme that has left a strong legacy.
