REISWIG Biology Department, University of Victoria Natural History Section, Royal British Columbia Museum P.O. Box 3020 Stn CSC, Victoria, British Columbia V8W 3N5 [email protected] MICHELLE KELLY Coasts and Oceans National Centre National Institute of Water & Atmospheric Research Private Bag 99940, Auckland 1149, New Zealand [email protected] Abstract Family Euplectellidae Gray, 1867 (Hexactinellida, Lyssacinosida) of the New Zealand Exclusive Economic Zone (EEZ) is reviewed, inventoried from existing and new collections, and revised where necessary. Collections within the NIWA Invertebrate Collection (NIC), the Museum of New Zealand Te Papa Tongarewa (NMNZ), and specimens from the NORFANZ mid-Tasman Sea survey, housed at the Queensland Museum (QM), have yielded well over 250 catalogued specimens, some of which are from the Australian EEZ and International waters. Prior to this work, our knowledge of euplectellid glass sponges in New Zealand waters was limited to three species, Regadrella okinoseana Ijima, 1896, Walteria leuckarti Ijima, 1896 and W. flemmingi Schulze, 1885, and eight unde- scribed species listed in Kelly et al. (2009). In 2017, a new species of Atlantisella, A. lorraineae Reiswig & Kelly, 2017, was described from Tangaroa Seamount on the Kermadec Ridge. This list of four known species has now been expanded to a total of 26 species, including an additional four species known from other locations and 18 new species. These 26 species represent each of the three subfamilies, Euplectellinae Gray, 1867, Corbitellinae Gray, 1872, and Bolosominae Tabachnick, 2002, and span 14 genera, three of which are new to science (Plumicoma gen. nov., Amphoreus gen. nov., Trychella gen. nov.). Four additional species, previously unknown in the New Zealand region, are redescribed: Euplectella imperialis Iji- ma, 1894; E. plumosum Tabachnick & Lévi, 2004; Bolosoma charcoti Tabachnick & Lévi, 2004; B. biocalum Tabachnick & Lévi, 2004. Three species from the Norfolk Ridge south of New Caledonia have been included as they are considered highly likely to be present in the New Zealand region, but have, thus far, not been collected: Placopegma plumicomum Tabachnick & Lévi, 2004; Bolosoma meridionale Tabachnick & Lévi, 2004, and Hyalostylus monomicrosclerus Tabach- nick & Lévi, 2004. Numerous records from the Australian EEZ occur in this work: Euplectella imperialis from Lord Howe Plateau and the Great Australian Bight and Walteria flemmingi from the latter locality; E. plumosum from Lord Howe Rise and Regadrella okinoseana from Lord Howe Rise, Norfolk Basin and Seamount 7, South Macquarie Ridge. New species, Regadrella australis sp. nov., is described from the Australian EEZ surrounding Macquarie Island, and other locations in the New Zealand EEZ. Records from International waters surrounding New Zealand include Euplectella imperialis from Lord Howe Plateau and R. okinoseana from Wanganella Bank and Louisville Seamount Chain. 8 Non-technical summary Glass sponges in the Family Euplectellidae (basket glass sponges) found in the New Zealand Exclusive Economic Zone (EEZ) are reviewed and revised by studying existing and new collections within the NIWA Invertebrate Collection (NIC), Museum of New Zealand Te Papa Tongarewa (NMNZ) and specimens from the NORFANZ mid-Tasman Sea survey, housed at the Queensland Museum in Brisbane. Studying these collections has yielded well over 250 catalogued specimens, some of which are from the Australian EEZ and International waters. Prior to this work, we only knew of three basket glass sponges in New Zealand waters: Regadrella okinoseana, Walteria leuckarti and W. flemmingi. In 2017, a new species, Atlantisella lorraineae, was described from Tangaroa Sea- mount on the Kermadec Ridge. This list of four known species has now been expanded to a total of 26 species, including an additional four species known from other locations and 18 new species. These 26 species are representative of the entire family Euplectellidae and span 14 genera, three of which are new to science (Plumicoma, Amphoreus, Trychella). Four species previously unknown in the New Zealand region are redescribed: Euplectella imperialis; E. plumo- sum; Bolosoma charcoti and B. biocalum. Three species from the New Caledonia EEZ have been included as they are considered highly likely to be present in the New Zealand region, but have, thus far, not been collected: Placopegma plumicomum; Bolosoma meridionale; Hyalostylus monomicrosclerus. Records from the Australian EEZ are included in this work: Euplectella imperialis, E. plumosum, Regadrella okinoseana and Walteria flemmingi are recorded from Lord Howe Plateau, Lord Howe Rise and Norfolk Basin in the north, Great Australian Bight, South Australia, and South Macquarie Ridge to the south of New Zealand. The type lo- cality of the new species Regadrella australis sp. nov. is Macquarie Ridge, in the Australian EEZ surrounding Macquarie Island; it is also recorded from the surrounding New Zealand EEZ. Records from International waters surrounding New Zealand include Euplectella imperialis from Lord Howe Plateau and R. okinoseana from Wanganella Bank and Louisville Seamount Chain.

  • An Integrative Systematic Framework Helps to Reconstruct Skeletal

    An Integrative Systematic Framework Helps to Reconstruct Skeletal

    Dohrmann et al. Frontiers in Zoology (2017) 14:18 DOI 10.1186/s12983-017-0191-3 RESEARCH Open Access An integrative systematic framework helps to reconstruct skeletal evolution of glass sponges (Porifera, Hexactinellida) Martin Dohrmann1*, Christopher Kelley2, Michelle Kelly3, Andrzej Pisera4, John N. A. Hooper5,6 and Henry M. Reiswig7,8 Abstract Background: Glass sponges (Class Hexactinellida) are important components of deep-sea ecosystems and are of interest from geological and materials science perspectives. The reconstruction of their phylogeny with molecular data has only recently begun and shows a better agreement with morphology-based systematics than is typical for other sponge groups, likely because of a greater number of informative morphological characters. However, inconsistencies remain that have far-reaching implications for hypotheses about the evolution of their major skeletal construction types (body plans). Furthermore, less than half of all described extant genera have been sampled for molecular systematics, and several taxa important for understanding skeletal evolution are still missing. Increased taxon sampling for molecular phylogenetics of this group is therefore urgently needed. However, due to their remote habitat and often poorly preserved museum material, sequencing all 126 currently recognized extant genera will be difficult to achieve. Utilizing morphological data to incorporate unsequenced taxa into an integrative systematics framework therefore holds great promise, but it is unclear which methodological approach best suits this task. Results: Here, we increase the taxon sampling of four previously established molecular markers (18S, 28S, and 16S ribosomal DNA, as well as cytochrome oxidase subunit I) by 12 genera, for the first time including representatives of the order Aulocalycoida and the type genus of Dactylocalycidae, taxa that are key to understanding hexactinellid body plan evolution.

In addition to the three species so far recorded in the region, we report Spongicola goyi for the first time, and formally describe three new species of Spongicolidae. Following the morphological review and DNA sequencing of type specimens, we propose the synonymy of Spongiocaris yaldwyni with S. neocaledonensis and review a proposed broad Indo-West Pacific distribution range of Spongicoloides novaezelandiae. New records for the latter at nearly 54◦ South on the Macquarie Ridge provide the southernmost record for stenopodidean shrimp known to date.

EXECUTIVE SUMMARY Clark, M.R.; Williams, A.; Rowden, A.A.; Hobday, A.J.; Consalvey, M. (2011). Development of seamount risk assessment: application of the ERAEF approach to Chatham Rise seamount features. New Zealand Aquatic Environment and Biodiversity Report No. 74. Seamounts, knolls, and hills are common features of New Zealand’s marine environment. They can host fragile benthic invertebrate communities (e.g., cold-water corals) that are highly vulnerable to human impacts, especially bottom trawling. Commercial fisheries on seamount features for species such as orange roughy are widespread throughout the EEZ, and hence developing a risk assessment for seamount habitat from the effects of bottom trawling has been a focus of research projects supported by both the Ministry of Fisheries and Foundation for Research, Science & Technology. An approach to ecological risk assessment widely used by the Australian Fisheries Management Authority to assess Australian fisheries is the Ecological Risk Assessment for Effects of Fishing (ERAEF).

However, the relationships and systematics within the common genus Rossella Carter, 1872 (Lyssacinosida: Rossellidae) are unclear and in need of revi- sion. The species content of this genus has changed dramatically over the years depend- ing on the criteria used by the taxonomic authority consulted. Rossella was formerly regarded as a putatively monophyletic group distributed in the Southern Ocean and the North Atlantic. However, molecular phylogenetic analyses have shown that Rossella is restricted to the Southern Ocean, where it shows a circum-Antarctic and subantarctic distribution. Herein, we provide a molecular phylogenetic analysis of the genus Rossella, based on mitochondrial (16S rDNA and COI) and nuclear (28S rDNA) markers.

    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.

All Chilean hexactinellid species occur in bathyal to abyssal depths (from 256 up to 4142 m); nine of them are reported for the Sala y Gomez and Nazca Ridges, with one species each in the Juan Fernandez Archipelago and Easter Island.
