E-mail: [email protected] Abstract Recent surveys on the benthic harpacticoids in the northwestern sector of the Caribbean have called attention to the lack of a list of species of this diverse group in this large tropical basin. A first checklist of the Caribbean harpacticoid copepods is provided herein; it is based on records in the literature and on our own data. Records from the adjacent Bahamas zone were also included. This complete list includes 178 species; the species recorded in the Caribbean and the Bahamas belong to 33 families and 94 genera. Overall, the most speciose family was the Miraciidae (27 species), followed by the Laophontidae (21), Tisbidae (17), and Ameiridae (13). Up to 15 harpacticoid families were represented by one or two species only.

  • Meiofauna of the Koster-Area, Results from a Workshop at the Sven Lovén Centre for Marine Sciences (Tjärnö, Sweden)

Todaro 9, W. Sterrer 10 and U. Jondelius 1 Abstract During a two-week workshop held at the Sven Lovén Centre for Marine Sciences on Tjärnö, an island on the Swedish west-coast, meiofauna was studied in a large variety of habitats using a wide range of sampling tech- niques. Almost 100 samples coming from littoral beaches, rock pools and different types of sublittoral sand- and mudflats yielded a total of 430 species, a conservative estimate. The main focus was on acoels, proseriate and rhabdocoel flatworms, rotifers, nematodes, gastrotrichs, copepods and some smaller taxa, like nemertodermatids, gnathostomulids, cycliophorans, dorvilleid polychaetes, priapulids, kinorhynchs, tardigrades and some other flatworms. As this is a preliminary report, some species still have to be positively identified and/or described, as 157 species were new for the Swedish fauna and 27 are possibly new to science. Each taxon is discussed separately and accompanied by a detailed species list.

NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The NOAA Technical Report NMFS Circular series continues a series that has been in existence since 1941. The Circulars are technical publications of general interest intended to aid conservation and management. Publications that review in considerable detail and at a high technical level certain broad areas of research appear in this series. Technical papers originating in economics studies and from management in- vestigations appear in the Circular series. NOAA Technical Report NMFS Circulars arc available free in limited numbers to governmental agencies, both Federal and State. They are also available in exchange for other scientific and technical publications in the marine sciences.

Zoological Studies 48(4): 493-507. A new species belonging to the Miraciidae Dana, 1846 (Copepoda: Harpacticoida: Miraciidae), is described from a seagrass bed dominated by Enhalus acoroides at Banpaklok, Phuket I., Thailand. An amended diagnosis of Typhlamphiascus includes: rostrum well-developed, expanded at the base with a small sensillum on each side of the rostrum about 1/5 from the acute tip. The new species, T. higginsi sp. nov., is similar to other species of the genus by having 8 segmented antennules, an almost linear body shape, and the baseoendopod of the 5th legs with fork-tipped setae. Autapomorphies of the new species are provided by the following characters: the inner edge of the basis of male 1st legs with only 3 chitinous lamellae; the dorsal edge of the female 1st abdominal somite ornamented with 1 row of 7 min spinules on each side, the armature of the abdominal somites furnished with rows of triangular spinules along the ventral edge of the 3rd and 4th somites in special patterns above the hyaline frills; the caudal ramus with a conical shape twice as long as broad, and the inner edge with 2 min spinules at the base.

With 33 figures A new harpacticoid copepod family collected from Australian sponges and the status of the subfamily Rhynchothalestrinae Lang RONY HUYS Marine Biology Section, <oology Institute, State University of Gent, X.L. Ledeganckstraat 35, B-9000 Gent, Belgium and Delta Institute for Hydrobiological Research, Vierstraat 28, 4401 EA Yerseke, The Jetherlands Received June 1989, accepted for publication Nouember 1989 A new family is proposed for Hamondia superba gen. et sp. nov., a shield-shaped harpacticoid collected from washings of sponges from Port Phillip, Australia. It is concluded that the closest relatives of the Hamondiidae fam. nov. currently belong to the heterogeneous thalestrid genus Rhynchothalestris Sars, 1905 and for that reason the latter is revised. Rhynchothalestris rufocincta (Brady, 1880) is redescribed and designated as type species for Ambunguipes gen. nov., comprising also the Indo-Pacific A. similis (A.Scott, 1909) which is re-instated. Ambunguipes uanhoeffii (Brady, 1910) is ranked as species inquirenda within the genus. Because of its body ornamentation R. conuta Geddes, 1969 is transferred to Lucayostratiotes gen. nov. The Ambunguipedidae fam. nov., accommodating Ambunguipes and Lucayostratiotes are regarded as the sister-group of the Hamondiidae on the basis of the loss of the seta on the first antennular segment, the presence of bifid spinules on the antennary exopod, the presence of a modified seta on the maxillary precoxal endite, the sexual dimorphism of leg 3, the detailed structure of the female genital complex, and the asymmetry of the male P6. The diagnosis of the subfamily Rhynchothalestrinae, encompassing the genera Rhynchothalestris and Peltthestris Monard, 1924 is amended, and a redescription of the former’s type species R.

Manuals will be published 'at irregular intervals on as many taxa of the region as there are specialists available to collaborate in their preparation. The manuals are an outgrowth of the widely used "Keys to Marine Invertebrates of the Woods Hole Region," edited by R. 1. Smith, published in 1964, and produced under the auspices of the Systematics-Ecology Program, Marine Biological Laboratory, Woods Hole, Mass. Instead of revising the "Woods Hole Keys," the staff of the Systematics-Ecology Program decided to expand the geographic coverage and bathymetric range and produce the keys in an entirely new set of expanded publications.

    Epibenthic Invertebrates at Two Beaches After Addition of Olympia Oysters, with Particular Reference to Prey of Juvenile Pacific Salmon Jeffery Cordell, Brenda Bachman, and Lucinda Tear University of Washington, School of Aquatic and Fishery Sciences 2 Summary 1. Epibenthic pump samples designed to quantify juvenile Pacific salmon prey taxa were taken at two beaches in Puget Sound, Washington, before and after addition of Olympia oysters. Before-oyster sampling occurred at two plots at each beach in 2006 once in April and once in May. In 2007, after oysters had been added to one of the plots at each beach, sampling occurred again. 2. Seventy-one taxa of epibenthic organisms were collected at the two beaches, twelve of which were juvenile prey salmon taxa. 3. Taxa richness before and after addition of oyster was similar at both beaches. 4. Samples were dominated by harpacticoid copepods, particularly the family Ectinosomatidae, and the juvenile salmon prey taxon Tisbe sp. 5. Densities of most taxa were higher in 2007 than in 2006. 6. Four-way Analysis of Variance, using treatment (oyster, no oyster), month, year, and location indicated that the treatment*year interaction was significant for many of the taxon densities, including total epibenthic organisms, total harpacticoids, and Tisbe sp. This resulted because the change in mean density from 2006 to 2007 was much greater in the oyster plots than in the no oyster plots. 7. We conclude that the addition of Olympia oysters to the two beaches studied increased overall epibenthic organism densities and those of the most abundant salmon prey harpacticoid copepods.
