In this study we introduce one new genus and five new species of cheilostome bryozoans based on material collected mainly at bathyal depths in the Subantarctic Southwest Atlantic by the vessels ARA Bahía Blanca, BO Puerto Deseado and RV Meteor. Bathyanasca incubatrix gen. nov., sp. nov., Chondriovelum perforatum sp. nov., Aspidostoma adeoniforme sp. nov., Talivittaticella bathyalis sp. nov. and Turritigera formidabilis sp. nov. are described and illustrated. Bathyanasca incubatrix, characterized by the lack of ovicells and the incubation of embryos within the autozooidal cavity, is tentatively classified in the family Calloporidae. Present results contribute to support the hypothesis of close faunal affinities between Antarctica and relatively deep areas around southern South America.
