Box A285, Sydney South, NSW 2000, Australia ABSTRACT. The polychaete fauna of the Hawkesbury River and some other estuarine areas in central and southern New South Wales is described. The majority of material comes from Merimbula, Jervis Bay, Port Hacking, Botany Bay, Hawkesbury River, Port Stephens and Broughton Island; often from seagrass habitats. The material from the Hawkesbury River has been collected over several years and detailed habitat and occurrence data are available. Over 180 species are recorded, of which 28 species and 4 genera are new: Harmothoe charlottae n.sp., Sthenelais pettiboneae n.sp., Compsanaitis inflata n.gen., n.sp., Podarke microantennata n.sp., Augeneria verdis n.sp., Schistomeringosjilijormis n.sp., Caulleriella dimorphosetosa n.sp., C. longisetosa n.sp., C. retusiseta n.sp., Chaetozone platycerca n.sp., Tharyx aphelocephalus n.sp., Lobochesis bibrancha n.gen., n.sp., L. longiseta n.sp., Ophelia elongata n.sp., O. multibranchia n.sp., Notomastus annulus n.sp., N. chrysosetus n.sp., N. estuarius n.sp., Polycirrus rosea n.sp., Pseudostreblosoma serratum n.gen., n.sp., Streblosoma atos n.sp., S. latitudinis n.sp., Longicarpus glandulus n.gen., n.sp., Nicolea amnis n.sp., Terebella pappus n.sp., Desdemona aniara n.sp., Euchone variabilis n.sp., and Laonome triangularis n.sp. For each species a full description is given except where a recent easily accessible description in English is available, in which case only a reference to that description is given. Habitat data where known is given together with the Australian distribution of the species. Many of the species are new records for Australia or for New South Wales. Keys to the families and species described in the paper are given. HUTCHINGS, PAT and ANNA MURRAY, 1984.

Gottfried Pillai Zoology Department, Natural History Museum, Cromwell Road, London SW7 5BD, United Kingdom absTracT. In 1988 Pat Hutchings of the Australian Museum, Sydney, undertook an extensive polychaete collection trip off the Kimberley coast of Western Australia, where such a survey had not been conducted since Augener’s (1914) description of some polychaetes from the region. Serpulids were well represented in the collection, and their present study revealed the existence of two new genera, and new species belonging to the genera Protula, Vermiliopsis, Hydroides, Serpula and Spirobranchus. The synonymy of the difficult genera Spirobranchus, Pomatoceros and Pomatoleios is also dealt with. Certain difficult taxa currently referred to as “species complexes” or “species groups” are discussed. For this purpose it was considered necessary to undertake a comparison of apparently similar species, especially of Spirobranchus, from other locations in Australia and the Indo-West Pacific region. It revealed the existence of many more new species, which are also described and discussed below. Pillai, T. Gottfried, 2009.

Box 94766, 1090 GT Amsterdam, The Netherlands cBamfield Marine Sciences Centre, Bamfield, British Columbia, Canada, V0R 1B0 Received 19 December 2005; accepted 2 June 2006 Abstract Phylogenetic relationships of (19) serpulid taxa (including Spirorbinae) were reconstructed based on 18S rRNA gene sequence data. Maximum likelihood, Bayesian inference, and maximum parsimony methods were used in phylogenetic reconstruction. Regardless of the method used, monophyly of Serpulidae is confirmed and four monophyletic, well- supported major clades are recovered: the Spirorbinae and three groups hitherto referred to as the Protula-, Serpula-, and Pomatoceros-group. Contrary to the taxonomic literature and the hypothesis of opercular evolution, the Protula- clade contains non-operculate (Protula, Salmacina) and operculate taxa both with pinnulate and non-pinnulate peduncle (Filograna vs. Vermiliopsis), and most likely is the sister group to Spirorbinae. Operculate Serpulinae and poorly or non-operculate Filograninae are paraphyletic. It is likely that lack of opercula in some serpulid genera is not a plesiomorphic character state, but reflects a special adaptation. r 2007 Gesellschaft fu¨r Biologische Systematik.

  • Biomineralization of Polychaete Annelids in the Fossil Record
    minerals Review Biomineralization of Polychaete Annelids in the Fossil Record Olev Vinn Department of Geology, University of Tartu, Ravila 14A, 50411 Tartu, Estonia; [email protected]; Tel.: +372-5067728 Received: 31 August 2020; Accepted: 25 September 2020; Published: 29 September 2020 Abstract: Ten distinct microstructures occur in fossil serpulids and serpulid tubes can contain several layers with different microstructures. Diversity and complexity of serpulid skeletal structures has greatly increased throughout their evolution. In general, Cenozoic serpulid skeletal structures are better preserved than Mesozoic ones. The first complex serpulid microstructures comparable to those of complex structures of molluscs appeared in the Eocene. The evolution of serpulid tube microstructures can be explained by the importance of calcareous tubes for serpulids as protection against predators and environmental disturbances. Both fossil cirratulids and sabellids are single layered and have only spherulitic prismatic tube microstructures. Microstructures of sabellids and cirratulids have not evolved since the appearance of calcareous species in the Jurassic and Oligocene, respectively. The lack of evolution in sabellids and cirratulids may result from the unimportance of biomineralization for these groups as only few species of sabellids and cirratulids have ever built calcareous tubes. Keywords: biominerals; calcite; aragonite; skeletal structures; serpulids; sabellids; cirratulids; evolution 1. Introduction Among polychaete annelids, calcareous tubes are known in serpulids, cirratulids and sabellids [1–3]. The earliest serpulids and sabellids are known from the Permian [4], and cirratulids from the Oligocene [5]. Only serpulids dwell exclusively within calcareous tubes. Polychaete annelids build their tubes from calcite, aragonite or a mixture of both polymorphs. Calcareous polychaete tubes possess a variety of ultrastructural fabrics, from simple to complex, some being unique to annelids [1].

Their diversity and simple macro- and 203 WOOD RESEARCH micromorphology of fungal structures have been major obstacles for more rapid progress in this regard. However, over the past two decades, there has been substantial progress in our understanding of genetic variability within traditionally recognized morphospecies. In this study we have overviewed genetic variation and phylogeography of macrofungi, which are important destroyers of wooden materials indoor of buildings. Several morphologically defined species of these fungal destroyers (Coniophora puteana, C. olivacea, C. arida, Serpula himantioides) have been shown to actually encompass several genetically isolated lineages (cryptic species). The protective efficacy against cryptic species within traditionally recognized morphospecies through laboratory tests (EN 113) and field trials (EN 252) might be sufficient to better prognosis of decay development in wooden materials for hazard assessment and for proper conservation and management plans.

  • Guide to the MEDITERRANEAN SIPUNCULANS
    Guide to the MEDITERRANEAN SIPUNCULANS Introduction Sipunculans, commonly known as peanut worms, are a group of exclusively marine benthic organisms. They are protostome, coe- lomate, unsegmented bilaterally symmetric invertebrates. Since the mid-twentieth century Sipuncula was considered an independ- ent phylum (Hyman 1959; Stephen 1964; Clark 1969; Stephen & Edmonds 1972), but nowadays this status is unclear and recent genetic studies would place the group within the phylum Annelida in a clade yet to be determined (e.g. Struck et al. 2007, 2011; Dordel et al. 2010). Sipunculans are likely to be placed in their own class in Annelida due to their distinctive features; e.g. lack of segmentation, U-shaped digestive tube and a sipunculan-specific larva (pelagosphera). From this perspective, in the present work no particular taxonomic rank has been assigned them. Nowadays, the sipunculans remain a group of little known and scarcely studied animals. This is mainly due to a lack of specialists (no more than 20 worldwide) and difficulties in species identifi- cation, since a detailed dissection is often required to clarify the details of their internal anatomy. Dissection is a difficult technique that requires skills and training, since most of the specimens are just a few mm in length. Moreover there is a lack of specific teach- ing materials. Although a few monographs aid in identification (Saiz-Salinas 1993; Cutler 1994; Pancucci-Papadopoulou et al. 1999), the information included is insufficiently illustrated, which is always a major problem. There are thus large gaps in the knowl- edge of this taxon. Unfortunately, most sipunculans collected in macrobenthic studies are not identified further than Phylum level, except for a few common species.

Previously, copper-based wood preservatives were commonly used for pressure treatment of wood for building construction, but some decay fungi are known to be copper tolerant. In this study, soil-block tests were undertaken to clarify the effect of copper, copper citrate, and alkaline copper quaternary-type D (ACQ-D) on the decay capabilities of S. lacrymans compared with an alternative wood preservative not containing copper. Twelve isolates of the dry rot fungus S. lacrymans and four other brown-rot species were evaluated for weight loss on wood treated with 1.2% copper citrate, 0.5% ACQ-D, and 0.5% naphthaloylhydroxylamine (NHA). Eleven out of 12 isolatcs of S. lacrymans were shown to be tolerant towards copper citrate. The ACQ-D and NHA preservatives, on the other hand, were both effective against the dry rot isolates.
