    The deep-water Xestoleberidinae Sars, 1928 (Crustacea: Ostracoda) in the Pliocene - Early Pleistocene of the M. San Nicola Section (Gela, Sicily)

    No full text
    Three species of the Xestoleberidinae Sars, 1928 have been found in the Plio-Pleistocene section of Monte S. Nicola (Sicily) which are x. pasta n. sp., X. prognata Bonaduce & Danielopol, 1988 and Platyleberis profunda (Breman, 1975). The ostracode assemblage of the section pertains without any doubt to the bathyal environment, a fact which confirms that the subfamily is not restricted to the shallow marine and brackish waters

    The Ostracode genus Sylvestra Doruk 1973: systematics, ecology and distribution

    The marine genus Sylvestra Doruk 1973 represented by Sylvestra posterobursa Doruk (type-species), S. seminis (Bonaduce, Masoli & Pugliese, 1976), S. bismuthi n. sp., S. delicatula n. sp., S. gravida n. sp., S. intermedia n. sp., S. moncharmonti n. sp., S. patriziae n. sp., S. ruggierii n. sp., S. tramontanoi n. sp. And S. virgula n. sp. All the new species are described and illustrated. From its distribution in the Recent, S. sylvestra can be defined as a shallow warm-water marker. Its occurrence in sediments from Tortonian to Holocene allows some paleoclimatic conclusions. The validity of the genus is discussed and confirmed

    The Ostracods in the palaeoenvironmental interpretation of the Late Langhian – Early Serravallian section of Ras il Pellegrin.

    The distribution of ostracods in the composed Langhian-Serravallian section of Ras il Pellegrin (Malta) has been studied quantitatively to define the evolution of both the assemblages and the palaeoenvironmental conditions. 99 samples have been examined at a stratigraphic distance of about 1 m. 78 species have been identified whose assemblages indicate an epibathyal environment and a sedimentation depth of 500-700 m. In particular, the almost continuous occurrence of the genus Oblitacythereis, which characterizes the water layer just above the psychrosphere, together with the absolute absence of the psychrospheric genus Agrenocythere confirm this interpretation. The sudden drop of both the simple diversity and abundance near the boundary "Upper Globigerina Limestone" - "Blue Clays" Formations, especially at the top of the succession, in our opinion may be due to the decrease of dissolved bottom oxygen content supported also by the Cytherellidae

    The genus Cytherella Jones, 1849 (Ostracoda) in the Italian Tortonian – Recent:

    Italian species of the genus Cytherella Jones, 1849 are studied from the Tortonian to Recent interval. Thirteen species are treated, 12 of which are illustrated. The lectotype and a paralectotype of Cythere ? serratula Brady, 1880 are also illustrated for comparison. Three species, Cytherella cercinata, C. gibba and C. vulgatella are described as new
