title: Two new species of cheilostome bryozoans from the South Atlantic Ocean .
abstract: Two new species of cheilostome bryozoans are described from Bahia and Espírito Santo States, Brazil-Calyptooecia conuma n. sp. and Hippotrema fissurata n. sp. Both genera are registered for the first time in the South Atlantic Ocean. Inter alia, Calyptooecia conuma n. sp. is characterized by the presence of dimorphic brooding zooids with relatively small orifices and no perioral tubercles, contrasting with bigger non-brooding zooids having larger orifices surrounded by perioral tubercles. Hippotrema fissurata n. sp. differs from congeners in colony morphology and colour, in details of the ooecium and in zooidal metrics. Specimens were collected on varied substrata, commonly calcareous nodules and shells as well as other bryozoans and sponges.
