【 摘 要 】

The ostracod associations of the Upper Pliocene-Pleistocene sedimentary succession out-cropping at Punta Mazza (Milazzo, Sicily NE) have been investigated. The ostracod fauna is often well-preserved and well-diversified: there 42 species belonging to 24 genera have been found. The association consists almost exclusively of bathyal taxa such as Bythocypris obtusata (Sars), B. bosquetiana (Brady), Henryhowella ex H. profunda Bonaduce et al. group, Quasibuntonia radiatopora (Seguenza), Retibythere (Bathybythere) scaberrima Brady, Pseudocythere caudata Sars and Bythocythere mylaensis Sciuto. Also, the Krithe group is well-represented with Krithe compressa (Seguenza) and K. pernoides (Bornemann). Further taxa such as Cytheropteron testudo Sars are rare. Almost all species, especially those belonging to Trachyleberididae Sylvester-Bradley are described, illustrated and commented on, including a new species, Acanthocythereis reticulata n.sp., found in the lower part of the section in Upper Pliocene sediment, is proposed as new. Finally, a specimen belonging to the genus Quasibuntonia Ruggieri is currently given in open nomenclature.
