Infante de Henrique 7, Areias São João, P-8200 Albufeira, Portugal; [email protected] 2Department of Geology, University of California at Davis, One Shields Avenue, Davis, CA 95616 USA; [email protected] *Corresponding author Received: 16 April 2012; revised version accepted 20 April 2012 The first occurrence of the cosmotropical pisaniine buccinid gastropod genus Engina Gray, 1839 was previously in the lower Gatun Formation (late Miocene) of Panama. Here we describe four new fossil species: E. cantaurana nov. sp., from the early Miocene of Venezuela (the oldest known species of Engina, with an unusually high spire), E. gigas nov. sp., from the late Miocene and early Pliocene of the Dominican Republic (the largest known Engina, with an erect inner lip and obsolete parietal denticle), E. latior nov. sp. from the late Miocene and early Pliocene of the Dominican Republic (a more typical species of Engina in terms of apertural dentition) and Engina moinensis nov. sp from the Pleistocene of Costa Rica and the Bocas del Toro Area (a species with possible paciphile affinities). We propose the new pisaniine genus Ameranna (type species: Anna florida García, 2008) for four living Carib- bean species and for two fossil species: A. primitiva nov. sp., from the early Miocene of Venezuela (the oldest known species of Ameranna) and the new Pliocene species A. minuscula nov. sp. from the Dominican Republic. The new genus differs from the early Oligocene to Recent eastern Atlantic genus Anna by having a lirate rather than denticulate outer lip.

  • ABSTRACT Title of Dissertation: PATTERNS IN
    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject.

Abstract Predatory gastropods of the superfamily Conoidea number over 12,000 living species. The evolutionary success of this lineage can be explained by the ability of conoideans to produce complex venoms for hunting, defense, and competitive interactions. Whereas venoms of cone snails (family Conidae) have become increasingly well studied, the venoms of most other conoidean lineages remain largely uncharacterized. In the present study, we present the venom gland transcriptomes of two species of the genus Clavus that belong to the family Drilliidae.

Deep-water species from the western Indian Ocean off the East African coast and Madagascar, belonging to the subfamily Photinae, are discussed and compared with species from the West Pacific. Phos elegantissimus Hayashi & Habe, 1965, P. hirasei Sowerby, 1913 and P. laevis Kuroda & Habe in Habe, 1961 are recorded from Mozambique and/or from Madagascar, hereby extending their known range considerably into the western Indian Ocean. The East African specimens formerly assigned to Phos roseatus Hinds, 1844 are found to differ from this West Pacific species. In total, five species are described as new: Phos ganii sp.

Sixty-seven species are recorded, of which 18 are new: Gibberula ligeriana nov. sp., Euthria presselierensis nov. sp., Mitrella clava nov. sp., Mitrella ligeriana nov. sp., Mitrella miopicta nov. sp., Mitrella pseudoinedita nov. sp., Mitrella pseudoblonga nov. sp., Mitrella pseudoturgidula nov. sp., Sulcomitrella sceauxensis nov. sp., Tritia turtaudierei nov. sp., Engina brunettii nov. sp., Pisania redoniensis nov. sp., Pusia (Ebenomitra) brebioni nov. sp., Pusia (Ebenomitra) pseudoplicatula nov. sp., Pusia (Ebenomitra) renauleauensis nov. sp., Pusia (Ebenomitra) sublaevis nov. sp., Episcomitra s.l. silvae nov. sp., Pseudonebularia sceauxensis nov. sp. Fusus strigosus Millet, 1865 is a junior homonym of F. strigosus Lamarck, 1822, and is renamed Polygona substrigosa nom. nov. Nassa (Amycla) lambertiei Peyrot, 1925, is considered a new subjective junior synonym of Tritia pyrenaica (Fontannes, 1879).
