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.
从巴西巴伊亚州和圣埃斯皮里图州描述了两种新的唇口目苔藓虫——康纳卡利普托苔藓虫（Calyptooecia conuma）新物种和裂沟希波苔藓虫（Hippotrema fissurata）新物种。这两个属均首次在南大西洋被记录。特别地，康纳卡利普托苔藓虫新物种的特征是存在具有相对小孔口且无口周瘤的双态育卵类虫体，与之形成对比的是具有较大孔口且被口周瘤包围的较大非育卵类虫体。裂沟希波苔藓虫新物种在群体形态和颜色、卵室细节以及类虫体尺寸方面与同属其他物种不同。标本采集于各种基质上，常见的有钙质结核、贝壳以及其他苔藓虫和海绵。
