ABSTRACT = {A new species of cyclopoid copepod, <i>Ozmana huarpium</i>, is described as a symbiont to <i>Pomacea canaliculata</i> (Lamarck 1822) (Caenogastropoda, Ampullariidae). Rather large numbers (about one hundred copepods per snail) were found, although there was no evidence of harm to the host. To our knowledge, <i>O. haemophila</i> (symbiont to <i>P. maculata</i>), and the currently described species, <i>O. huarpium</i>, are the only copepod species ever recorded as endosymbionts to freshwater invertebrates. While <i>O. haemophila</i> is restricted to the haemocoel of its host, <i>O. huarpium</i> predominate in the penis sheath, the ctenidium and the mantle cavity, figuring in these pallial organs 63-65 % of total mature forms. The sex ratio of the symbiont is skewed to the female side in these organs, specially in male hosts. The hypothesis that a special female tropism for the male host’s pallial organs might ensure interindividual transmission of the symbiont was tested, with indications that the symbiont is mainly transmitted during copulation.},
