N2 - © 2015, Gesellschaft für Biologische Systematik.Paramecium is one of the best known and most intensely studied ciliate genera. It currently comprises 18 morphospecies including the P. aurelia complex of 15 sibling species. Here, we describe the new morphospecies Paramecium buetschlii sp. nov. from a freshwater pool in Norway, featuring unusual combinations of morphological characters and a high genetic diversity relative to other congeners. Three further investigated Paramecium spp. from Germany, Hungary, and Brazil are treated as cryptic species, because they are difficult to discriminate from other members of the genus relying on morphological criteria only. However, DNA-based taxonomic markers (18S-rDNA and mitochondrial COI) clearly indicate they are separate species. Due to the lack of an appropriate systematic term within the International Code of Zoological Nomenclature for distinguishing cryptic from valid biological species, we propose the provisional status Eucandidatus as a component of the taxonom
