Format : 27 cm ISBN/ISSN/EAN : 978-2-85653-642-1 Langues : Français (fre) Index. décimale : 594 Mollusques Résumé : The Pyramidellidae are a species-rich family of small gastropods which live as ectoparasites on other marine invertebrates. Their subtle variations around a quite homogenous basic morphology make species-level taxonomy extremely difncult. This volume contains the descriptions of 272 species collected in the last 30 years of deep-sea benthic exploration promoted by MNHN and IRD scientists. More than three-quarters of the species are new to science, and more is to corne with the other genera to be studied following Turbonilla. This paper takes a step forward towards answering some questions regarding the mega-diverse Indo-Pacific. What is really the order of magnitude of species richness? How are numbers of individuals distributed among species? How heterogeneous is the fauna on a géographie scale? Anselme Penas and Emilio Rolan have a considarable background in malacology, mostly European and Eastern Atlantic. Their venture with the Pyramidellidae started with the European and West African species, in a series of papers which appeared in the Sjanish malacological journal Iberus, in which new species appeared by the dozens. The move to the Indo-Pacific goes sp one order of magnitude, and only the great XIX century expéditions match similar numbers of new species introdftced in a single paper.
