Twelve species of the genus Oswaldella Stechow have been studied, eight of which are new to science (Oswaldella delicata sp. nov., O. encarnae sp. nov., O. garciacarrascosai sp. nov., O. gracilis sp. nov., O. grandis sp. nov., O. incognita sp. nov., O. obscura sp. nov. and O. rigida sp. nov.), originating from the Weddell Sea and collected by several antarctic expeditions with R.V. Polarstern. Each is described and figured, its systematic position is considered and current data concerning its autecology and geographical distribution are given. Finally, a comparative table is presented including the principal features of all known species of the genus. Descriptors: OSWALDELLA DELICATA new species; OSWALDELLA ENCARNAE new species; OSWALDELLA GARCIACARRASCOSAI new species; OSWALDELLA GRACILIS new species; OSWALDELLA GRANDIS new species; OSWALDELLA INCOGNITA new species; OSWALDELLA OBSCURA new species; OSWALDELLA RIGIDA new species
