ISSN 0067 1975 The Amphitritinae (Polychaeta: Terebellidae) from Australia PAT HUTCHINGS AND CHRIS GLASBY Australian Museum, P.O Box A285, Sydney South, NSW 2000, Australia ABSTRACT. The amphitritine fauna of Australia comprises 17 genera and 37 species. These are described, and a key to the genera and Australian species is provided. Twenty one new species and one new genus are described: Amphitrite pachyderma n. sp., Amphitritides harpa n. sp., A. ithya n. sp., Arranooba booromia n. gen" n. sp., Bafjinia biseriata n. sp., Eupolymnia koorangia n. sp., Lanassa exelysis n. sp., L. ocellata n. sp., Lanicides fascia n. sp., L. lacuna n. sp., L. tribranchiata n. sp., Lanice bidewa n. sp., Loimia batilla n. sp., L. triloba n. sp., Neoleprea macrocercus n. sp., Phisidia echuca n. sp., Pista australis n. sp., P. sinusa n. sp., P. turawa, n. sp., Reteterebella aloba n. sp. and Terebella maculata n. sp., and the following new combination Longicarpus modestus. A full descript,ion of all Australian species of this subfamily is given except when a recent description is available. HUTCHINGS, P.A. and CJ. GLASBY, 1988.

This paper describes the Australian Amphitritinae Fauchald's (1977) generic definitions of the (F.

They comprised 10 338 individuals in 1722·7 g dry weight of polychaete tubes, with Echino- dermata, Polychaeta (not identified to species) and Crustacea as the dominant taxa. The Shannon–Wiener diversity index did not vary seasonally, only two species (a holothurian and a pycnogonid) showing seasonal variation. Ophiactis savignyi was the dominant species, providing 45·5% of individuals. Three other ophiuroids, the holothurian Synaptula hidriformis, the crustaceans Leptochelia savignyi, Megalobrachium soriatum and Synalpheus fritzmuelleri, the sipunculan Themiste alutacea and the bivalve Hiatella arctica were all abundant, but most of the 68 species recorded occurred sparsely.

  • <I>Lanice Conchilega</I>
    BULLETIN OF MARINE SCIENCE, 48(2): 517-523, 1991 BROMO PHENOLS IN LANICE CONCHILEGA (POL YCHAET A, TEREBELLIDAE): THE INFLUENCE OF SEX, WEIGHT AND SEASON Helmut Goerke and Kurt Weber ABSTRACT The levels of four brominated compounds in Lanice conchilega were measured: 2,4-di- bromophenol (I), 2,6-dibromo-4-methylphenol (2), 2,4,6-tribromophenol (3), 3,5-dibromo- 4-hydroxybenzaldehyde (4). The presence of all four of these secondary metabolites in the j.lg/grange was species specific. Ten other terebellid species did not contain the compounds in significant concentrations. The levels in L. conchilega were not dependent on animal size, sex or seasons. Bromophenols were not detected in plankton and only (3) was found in sea water (2 pg.g-I) near the sites of dense populations of the annelid. The compounds are generally not accumulated, which was tested by feeding pieces of L. conchi/ega to three marine invertebrate spllcies. Bromophenols are known as secondary metabolites in various Enteropneusta (Higa, 1981; King, 1986; Woodin et aI., 1987), in Phoronidea, Phoronopsis viridis (Sheikh and Djerassi, 1975), and in Polychaeta, Lanice conchilega and Arenicola cristata (Weber and Ernst, 1978; Woodin et aI., 1987). The compounds exhibit antimicrobial activity and are possibly of antiseptic importance for wound healing in bottom living species (Sheikh and Djerassi, 1975). King (1986) suggested that a dibromophenol inhibits the aerobic microbial degradation of the burrow-wall mucous lining. There is little information on the concentrations of the compounds in the taxa mentioned above, and it is not known whether the compounds are predominant during particular growth stages or under specific environmental conditions.

    Family Terebellidae Marine Sediment Monitoring Puget Sound Polychaetes: Family Terebellidae Family Terebellidae General characters (from Hilbig, 2000) Body divided into anterior thorax (notopodia and neuropodia present) and posterior abdomen (neuropodia only). Prostomium reduced and fused with peristomium; having an anterior upper lip and posterior tentacular membrane (tentacular membrane bearing numerous nonretractile tentacles (long in life, short when preserved)). (Ampharetidae can retract their buccal tentacles.) Eyespots sometimes present, located above and behind the reduced, belt-like prostomium. First 2-3 segments without setae; may bear branchiae dorsally and/or lateral to ventrolateral membranous flaps called lateral lappets. Branchiae present or absent (genus level characteristic); when present, located on a few anterior segments, usually segments 2 to 5; may be simple and cylindrical, arborescent, or bottle-brush shaped (number of gills is species level characteristic). Thoracic parapodia biramous; notopodia cylindrical bearing simple setae, usually limbate capillaries; thoracic neuropodia usually present, usually avicular uncini. Abdominal parapodia uniramous or without setae; notopodia lacking; neurosetae, when present, usually consist of avicular uncini. Pygidium simple, without anal cirri or lobes. (Usually absent from specimens, but it is unremarkable.) There are a couple of genera with no neurosetae in the abdomen. Neurosetae are variable…spines to uncini. Common species of Terebellidae found in Puget Sound Genus Polycirrus No gills. Anterior has glandular ventral shields…staining patterns are important. Many species, but not many are described. In Hobson and Banse, 1981, they are numbered with Roman numerals. Good info from Larry Lovell, 1995, a key with a nice table of provisional species…also, there is a key with the staining patterns.

  • <I>Eupolymnia Nebulosa</I> (Polychaeta, Terebellidae)
    BULLETIN OF MARINE SCIENCE, 48(2): 420-431, 1991 LARVAL RELEASE FROM THE EGG MASS AND SETTLEMENT OF EUPOLYMNIA NEBULOSA (POL YCHAETA, TEREBELLIDAE) Michel R. Bhaud ABSTRACT The study of distribution and abundance of soft-substrate organisms can be examined by the recruitment mechanisms of the species involved. A study was carried out on Eupolymnia nebu/osa (Polychaeta, Terebellidae), starting from the release of larvae from the egg mass through the initial tube formation. The liberation of larvae, e){tending over 10 days, was counter-balanced by a marked synchrony at the time of settlement which occurred over a 2-day period for nearly 70% of the larvae. Despite the morphological differences present at the time of liberation, settlement took place at the same morphological stage. The duration of the planktonic life varied in relation to the time ofrelease from the egg mass. The larvae were provided with sufficient energy reserves to reach the first benthic stage. At this point, the most essential requirement is the construction of the first tube. Later, two basic require- ments arise: food, and material for the prolongation of the tube. Both are satisfied by input from sedimentation. The synchronized settlement period caused a negative inter-individual effect, which tended to distance the individuals from each other, resulting in an even distri- bution pattern. The dynamics of benthic communities are subject to fluctuations, which are due for the most part to the different life history strategies of the species involved. Therefore, study of the most abundant species, whose presence in a community is likely to be the most influential, would appear to be essential.

These fairly large and cephalized polychaetes are often characterized by extendible feeding tentacles and brightly colored brachial plumes that extend from their anterior region (Fig 1) (Fauchald & Jumars 1979, Rouse 2001). These long feeding tentacles are associated with a sessile benthic lifestyle as their flexibility and length allow for selective feeding on deposits of diatoms, unicellular algae, and various small invertebrate larvae living within the sediment (GrCmare 1988). Many species of terebellid worms use their tentacles to build tubes (Fig 1) (Fauchald & Jumars 1979, Rouse 2001), selecting low-density detrital matter as their construction material. To build a tube the tentacles produce mucus, which adheres to the particles allowing their extraction from the surrounding sediment. Using cilia along the ciliary grooves of each tentacle, terebellids transport particles to their mouth or down the length of their body for tube building. Their tubes vary in construction material, size, and shape (Gremare 1988). For example, the tube of the local species Pista Paczjca has a stiff chitonous tube, characterized by a frayed oral hood and can be up to 1 meter in length. Meanwhile, the local species Thelepus crispus builds extensive sediment tubes on rock surfaces in the intertidal (Harrnan 1969). In terms of tube building, selection pressure favors individuals that can build sturdy tubes efficiently as a tube offers protection from sunlight and predators (Duchgne 2004).
