Notes

The genera Acineria, Trimyema and Trochiliopsis are reviewed. The revision is based on an investigation of each of the type-species, namely Acineria incurvata Dujardin, Trimyema compressa Lackey, and Trochiliopsis opaca Penard, which were found in a sewage-treatment plant. Acineria comprises three species; A. incurvata, A. nasuta, and A. uncinata. A. acuta is a synonym of A. incurvata. Trimyema comprises eight species; T. alfredkahli, T. claviformis, T. compressa, T. echinometrae, T. kahli, T. marina, T. minuta and T. pleurispiralis but T. alfredkahli and T. claviformis are perhaps synonyms of T. marina. Trochiliopsis is monotypic and new for the fauna of Austria. This genus is apparently closely related to the autochthonous soil ciliate Stammeridium kahli.
