In den WarenkorbThe Atlantic species which we attribute to the genera Chrysallida s.l. (Heterostropha, Pyramidellidae) cited or found in the West coast of Africa, from the Mediterranean until South Africa, are revised. In total we consider 44 taxa with specific validity, from which 4 are cited by first time in the study area (C. emaciata, C. gh…isotti, C. nivosa and C. palazzii), for 11 the known distribution area is enlarged (C. clathrata, C. dimidiata, C. dollfusi, C. excavata, C. fenestrata, C. impercepta, C. interstincta, C. intumescens, C. juliae, C. sergei and C. sigmoidea), 12 are new for science. All them are described and most of them are figured. Further more some taxa considered valid until now are passed at synonymy. At the end of the work a dicotomic key for the identification of all the signalized species, a table showing their geographic distribution and a synonymy list, are presented. New taxa: Chrysallida verdensis n. sp., Chrysallida manonegra n. sp., Chrysallida sixtoi n. sp., Chrysallida jordii n. sp., Chrysallida pinguis n. sp., Chrysallida gubbiolii n. sp., Chrysallida pyrgulina n. sp., Chrysallida herosae n. sp., Chrysallida anselmoi n. sp., Chrysallida mauritanica n. sp., Chrysallida pelorcei n. sp., Chrysallida eugeniae n. sp., 73 pp., 176 figs, br. gr. 8.

In den WarenkorbThe present work is the first of a series in which the Pyramidellidae of the Red Sea will be studied. We start with the tribe Chrysallidini, which includes the genera Helodiamea (2 species), Strioturbonilla (1), Parthenina (12), Pyrgulina (20), Chrysallida (1), Costabieta (1), Miralda (4), Oscilla (10), Pseudoscilla (1) and Babe…lla (6). In total there are 58 species, of which 34 are new to science. One species has a preoccupied name and is renamed. Whenever we were able to photograph the type material of the different species, such photos are shown, and the new species are studied, described and represented through micrographs made with the canning electron microscope. New taxa: Helodiamea prima n. sp., Helodiamea firma n. sp., Strioturbonilla irregularis n. sp., Parthenina perpetua n. sp., Parthenina elegantiae n. sp., Parthenina tavianii n. nom., Parthenina convoluta n. sp., Parthenina sudanensis n. sp., Parthenina nexa n. sp., Parthenina perforata n. sp., Parthenina unavera n. sp., Pyrgulina carmeloi n. sp., Pyrgulina isae n. sp., Pyrgulina permansa n. sp., Pyrgulina quinqueflexa n. sp., Pyrgulina permanens n. sp., Pyrgulina lineotuber n. sp., Pyrgulina microtuber n. sp., Pyrgulina scabra n. sp., Pyrgulina minusgranum n. sp., Pyrgulina condita n. sp., Pyrgulina lacrima n. sp., Pyrgulina erecta n. sp., Pyrgulina linomicalii n. sp., Pyrgulina prosorbis n. sp., Chrysallida yuamaniaensis n. sp., Oscilla mirifica n. sp., Oscilla aqabaensis n. sp., Oscilla virginiae n. sp., Oscilla multistriata n. sp., Pseudoscilla montseromansae n. sp., Babella ovalis n. sp., Babella micronodulosa n. sp., Babella nimiaprocostae n. sp., Babella maestratii n. sp. 98 pp., 45 figs, br. gr. 8.

In den WarenkorbThe 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 difficult. This volume contains the descriptions of 272 species collected in the last 30 years of dee…p-sea benthic exploration promoted by MNHN and IRD scientists. More than three-quarters of the species are new to science, and more is to come 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 geographic scale? Anselmo Peñas and Emilio Rolán have a considerable 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 Spanish malacological journal Iberus, in which new species appeared by the dozens. The move to the Indo-Pacific goes up one order of magnitude, and only the great XIX century expeditions match similar numbers of new species introduced in a single paper. 436 pp., 156 partly col. pls, hardcover 4 [22 x 27.7 cm].
