ZooKeys 488: 1–29. doi: 10.3897/zookeys.488.9061 Abstract In November 2012, a workshop was carried out on the taxonomy and systematics of the family Syllidae (Annelida: Phyllodocida) at the Dove Marine Laboratory, Cullercoats, Tynemouth, UK for the National Marine Biological Analytical Quality Control (NMBAQC) Scheme. Illustrated keys for subfamilies, genera and species found in British and Irish waters were provided for participants from the major national agencies and consultancies involved in benthic sample processing. After the workshop, we prepared updates to these keys, to include some additional species provided by participants, and some species reported from nearby areas. -

Zootaxa, Loandalia (Polychaeta: Pilargidae)
Zootaxa 1119: 59–68 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1119 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) New species of Loandalia (Polychaeta: Pilargidae) from Queensland, Australia SHONA MARKS1 & SCOTT HOCKNULL2 1 S. A. Marks. CSIRO Marine Research, PO Box 120, Cleveland QLD 4163. [email protected]. 2 S. A. Hocknull. Queensland Museum, 122 Gerler Rd Hendra QLD 4711. [email protected] Abstract Two new species of Loandalia are described from Queensland, Australia. Loandalia fredrayorum sp. nov. is described from Moreton Bay, south eastern Queensland and is distinguished from all other species of Loandalia by the presence of singular palpostyles; uniramous parapodia at chaetiger 1; an emergent notopodial spine at chaetiger 9; neurochaetae numbering 20–24; ventral cirri begin on chaetiger 7 and the pygidium with two lateral papillae-like anal cirri. Loandalia gladstonensis sp. nov. is described from Gladstone Harbour, central eastern Queensland and is distinguished from all other species of Loandalia by the presence of bifid palpostyles; chaetiger 1 uniramous with remaining chaetigers biramous; an emergent notopodial spine from chaetiger 7–8; ventral cirri present from chaetiger 5 and neurochaetae numbering 5–6. Key words: Loandalia fredrayorum sp. nov., Loandalia gladstonensis sp.nov., Pilargidae, Queensland, Australia, new species, systematics. Introduction Saint-Joseph (1899) established the Pilargidae for the new species Pilargis verrucosa Saint-Joseph. Prior to this, pilargids had been placed in several different families including the Syllidae, Hesionidae and Polynoidae (Licher & Westheide 1994). Recent cladistic analyses of the Phyllodocida firmly recognise Pilargidae as a distinct clade (Glasby 1993; Pleijel & Dahlgren 1998). -

The Namanereidinae (Polychaeta: Nereididae). Part 1, Taxonomy and Phylogeny
© Copyright Australian Museum, 1999 Records of the Australian Museum, Supplement 25 (1999). ISBN 0-7313-8856-9 The Namanereidinae (Polychaeta: Nereididae). Part 1, Taxonomy and Phylogeny CHRISTOPHER J. GLASBY National Institute for Water & Atmospheric Research, PO Box 14-901, Kilbirnie, Wellington, New Zealand [email protected] ABSTRACT. A cladistic analysis and taxonomic revision of the Namanereidinae (Nereididae: Polychaeta) is presented. The cladistic analysis utilising 39 morphological characters (76 apomorphic states) yielded 10,000 minimal-length trees and a highly unresolved Strict Consensus tree. However, monophyly of the Namanereidinae is supported and two clades are identified: Namalycastis containing 18 species and Namanereis containing 15 species. The monospecific genus Lycastoides, represented by L. alticola Johnson, is too poorly known to be included in the analysis. Classification of the subfamily is modified to reflect the phylogeny. Thus, Namalycastis includes large-bodied species having four pairs of tentacular cirri; autapomorphies include the presence of short, subconical antennae and enlarged, flattened and leaf-like posterior cirrophores. Namanereis includes smaller-bodied species having three or four pairs of tentacular cirri; autapomorphies include the absence of dorsal cirrophores, absence of notosetae and a tripartite pygidium. Cryptonereis Gibbs, Lycastella Feuerborn, Lycastilla Solís-Weiss & Espinasa and Lycastopsis Augener become junior synonyms of Namanereis. Thirty-six species are described, including seven new species of Namalycastis (N. arista n.sp., N. borealis n.sp., N. elobeyensis n.sp., N. intermedia n.sp., N. macroplatis n.sp., N. multiseta n.sp., N. nicoleae n.sp.), four new species of Namanereis (N. minuta n.sp., N. serratis n.sp., N. stocki n.sp., N. -

During the reproductive period, the benthic marine worms leave the ocean floor and swim to the surface to spawn, using bioluminescent light for mate attraction. The behavioral aspects of the courtship ritual have been extensively investigated, but little is known about the origin and evolution of light production in Odontosyllis, which might in fact be a key factor shaping the natural history of the group, as bioluminescent courtship might promote speciation. -
A New Cryptic Species of Neanthes (Annelida: Phyllodocida: Nereididae)
RAFFLES BULLETIN OF ZOOLOGY 2015 RAFFLES BULLETIN OF ZOOLOGY Supplement No. 31: 75–95 Date of publication: 10 July 2015 http://zoobank.org/urn:lsid:zoobank.org:pub:A039A3A6-C05B-4F36-8D7F-D295FA236C6B A new cryptic species of Neanthes (Annelida: Phyllodocida: Nereididae) from Singapore confused with Neanthes glandicincta Southern, 1921 and Ceratonereis (Composetia) burmensis (Monro, 1937) Yen-Ling Lee1* & Christopher J. Glasby2 Abstract. A new cryptic species of Neanthes (Nereididae), N. wilsonchani, new species, is described from intertidal mudflats of eastern Singapore. The new species was confused with both Ceratonereis (Composetia) burmensis (Monro, 1937) and Neanthes glandicincta Southern, 1921, which were found to be conspecific with the latter name having priority. Neanthes glandicincta is newly recorded from Singapore, its reproductive forms (epitokes) are redescribed, and Singapore specimens are compared with topotype material from India. The new species can be distinguished from N. glandicincta by slight body colour differences and by having fewer pharyngeal paragnaths in Areas II (4–8 vs 7–21), III (11–28 vs 30–63) and IV (1–9 vs 7–20), and in the total number of paragnaths for all Areas (16–41 vs 70–113). No significant differences were found in the morphology of the epitokes between the two species. The two species have largely non-overlapping distributions in Singapore; the new species is restricted to Pleistocene coastal alluvium in eastern Singapore, while N. glandicinta occurs in western Singapore as well as in Malaysia and westward to India. Key words. polychaete, new species, taxonomy, ragworm INTRODUCTION Both species are atypical members of their respective nominative genera: N.
