  A Well, 1-SPS-9 (25°51’S; 45°36’W), was drilled in an area of the Santos Basin, southern Brazil. The well’s lower level reached evaporites from the gulf phases. At the upper level, the well ranges into Recent sediments. From this well, forty nine cutting samples from the Late Cenozoic were analyzed. The following twenty-six ostracode species were recovered: Krithe trinidadensis Bold, 1958; K. gnoma Do Carmo & Sanguinetti 1999; K. pernoides Bornemann, 1855;

  K. morkhoveni Bold, 1960; K. minima Coles, Whatley & Moguilevsky, 1994; Krithe sp.1;

  Parakrithe sp. 1; Henryhowella macrocicatricosa Whatley et al., 1998; H. heros Whatley et al., 1996;

  Henryhowella sp. 1; Coquimba sp. 1; Eucythere sp. 1; Eucythere sp. 2; Argilloecia tenuis Ciampo, 1981; Loxoconcha sp. 1; Semicytherura sp.

  1; Munseyella sp. 1; Bradleya pelotensis Sanguinetti et al., 1991; Costa riograndensis Sanguinetti et al., 1992; Bairdoppilata triangulata Edwards, 1944; Neonesidea sp. 1; Neonesidea sp. 2; Cytherella sp. 1; Cytherella sp. 2; Cytherella sp. 3; Cytherella sp. 4.

  Quarenta e nove amostras de calha provenientes da perfuração 1-SPS-9 (25°51S; 45°36W) offshore, foram analisadas, correspondentes ao intervalo Oligoceno-Pleistoceno da Bacia de Santos. No Brasil, os ostracodes deste intervalo tem sido pouco estudados, apesar de sua importância para analise de bacia sedimentar. Neste trabalho são identificadas 26 espécies: Krithe trinidadensis Bold, 1958; K. gnoma Do Carmo & Sanguinetti 1999; K. pernoides (Bornemann, 1855); K. morkhoveni Bold, 1960; K. minima Coles, Whatley & Moguilevsky, 1994; Krithe sp. 1; Parakrithe sp. 1; Henryhowella macrocicatricosa Whatley et al., 1998; H. heros (Whatley et al., 1996); Henryhowella sp. 1; Coquimba sp. 1; Eucythere sp. 1; Eucythere sp. 2; Argilloecia tenuis Ciampo, 1981; Loxoconcha sp. 1; Semicytherura sp. 1; Munseyella sp. 1; Bradleya pelotensis Sanguinetti et al., 1991; Costa riograndensis Sanguinetti et al., 1992; Bairdoppilata triangulata Edwards, 1944; Neonesidea sp. 1; Neonesidea sp. 2; Cytherella sp. 1; Cytherella sp. 2; Cytherella sp. 3; Cytherella sp. 4.
