The Lioconcha Castrensis Species Group (Bivalvia : Veneridae), with the Description of Two New Species

Email: [email protected] Abstract Part of the genus Lioconcha Mörch, 1853 is reviewed. Species strongly resembling Lioconcha castrensis (Linnaeus, 1758) are discussed and two new species are described: Lioconcha arabaya n. sp. from the Northwest Indian Ocean and Lioconcha rumphii n. sp. from Thailand and Sumatra. These three species, together with Lioconcha macaulayi Lamprell & Healy, 2002, share many morphological similarities and we suspect them to be closely related. They are referred to as the Lioconcha cast- rensis species group. Furthermore, lectotypes of Venus castrensis Linnaeus, 1758, and Venus fulminea Röding, 1798, are desig- nated. The latter is considered a junior synonym of V. castrensis.

(Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
© Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed. -

En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos). -
Imported Food Risk Statement Bivalve Molluscs and Domoic Acid
Imported food risk statement Bivalve molluscs and domoic acid Commodity: Bivalve Molluscs. This includes whole or portions of bivalve molluscs that are fresh, frozen, dried or canned, such as cockles, clams, mussels, oysters and scallops. The following products are excluded and therefore not covered by this risk statement: cephalopod molluscs (e.g. squid, octopus, cuttlefish) and jelly fish marinara mix. Analyte: Domoic acid (DA) Recommendation and rationale Is DA in bivalve molluscs a medium or high risk to public health: Yes No Uncertain, further scientific assessment required Rationale: Consumption of seafood containing DA has resulted in human poisoning incidents and deaths. DA is a potent neurotoxin that causes amnesic shellfish poisoning (ASP) within 24-48 hours following ingestion. There is no antidote for ASP. DA is not destroyed by cooking, freezing or other food processing. General description Nature of the analyte: DA is a water-soluble, non-protein amino acid. It is produced by some marine diatoms of the genus Pseudo- nitzschia spp., which are likely to be present to some extent in most coastal marine environments. Isomers of DA are less toxic. Domoic acid is not reliably destroyed by common cooking methods (Vidal et al. 2009) or by autoclaving (McCarron and Hess 2006). Adverse health effects: DA is a potent neurotoxin that causes amnesic shellfish poisoning (ASP) within 24-48 hours following ingestion. There is no antidote for ASP. Clinical signs of acute DA toxicity (or ASP) are mild gastrointestinal symptoms (vomiting, diarrhoea, and abdominal pain) from an oral dose ranging between 0.9 and 2 mg DA/kg bw. -
Miscellaneous Mollusc Resources of Pacific Islands

Lewis Introduction l Molluscs (Phylum Molluscs) we a diverse array of "shellfish", which include bivalves (clams, cockles, oysters, mussels - Class Pelecypoda) ,gastropods ( snails, abalone, seahares- Class Gastropods) and cephalopods (squids, octopus, cuttlefish - Class Cephalopoda). These support large marine fisheries, world landings of molluscs exceeding 6 millions tonnes in 1985 (Anon, 1987) and dominated by cephalopods ( 1.67 million mt,), clams, cockles and arkshells ( 1.6 1 million mt.) and oysters ( 1.03 million mt). 2. Previous sessions at the workshop have considered in detail the molluscs of major commercial importance to Pacific Islands. This include molluscs harvested primarily for Industrial purposes (eg. trochus, green snail and pearl shell, for their nacreous shell interiors) as well as those harvested primarily for human consumption (giant clams). 3. There is in addition, however a wide range of molluscs harvested throughout the Pacific Islands for subsistence purposes and in some cases small scale commercial exploitation. Many are gleaned from a variety of inshore habitats, including mud flats, mangrove roots, sandy beaches, reef flats and rubble areas. These molluscs are commonly collected by women, and have traditionally served as important reserve food sources during times of bad weather or poor line fishing. In (tensely populated atolls, they may become a primary fooAsource, Zann ( 1985) noting that in South Tarawa (Kiribati), landings of three lagoon bivalves exceed that of all finfish combined. 4.

It is native to the north-eastern coasts species of sea snails, of the Atlantic Ocean, including northern Spain, France, commonly referred to as England, Scotland, Ireland, Scandinavia and Russia and has been periwinkles. They have a introduced to the Atlantic coast of North America. It is now a global distribution. Within predominant mollusc from New Jersey to Newfoundland. In this family of periwinkles Canada, their range includes New Brunswick, Nova Scotia, there are several genera, Quebec, Newfoundland and Labrador. one of which is Litttorina. They are plentiful at Burntcoat Head. Habitat Though most abundant on rocky substrates and common in tide In the Atlantic it is found pools, it is a habitat generalist that also occurs on muddy or on both open coast and sandy bottoms. They are found along the entire coast, on estuary habitats from the breakwaters, dikes, piers, etc. In favourable habitats, it reaches upper intertidal zone to densities of up to 200-800 individuals per square metre. about 40 metres deep, and Since its arrival in North America it has become the most can tolerate salinities down abundant shallow-water herbivorous snail from Nova Scotia to to around 13 ppt.
