摘要

Although testate amoebae have attracted great interest of protistologists for more than a century, some groups, especially those with a hyaline, organic test (=theca) are still poorly known. One of those is the genus Lecythium Hertwig et Lesser, 1874. Only recently Lecythium spp. were characterized by morphological and molecular means, but data on the type species Lecythium hyalinum Hertwig et Lesser, 1874, was still lacking. In this study, we screened for L. hyalinum in freshwater samples of Germany and the Netherlands. Four different isolates of L. hyalinum and one novel species were cultured and characterized by light microscopy. Phylogenetic analyses based on the small ribosomal subunit (SSU) RNA gene show that the genus Lecythium forms two robust clades, one forming a sister group to the Rhizaspididae/Pseudodifflugiidae clade (Tectofilosida), the other branching within ‘Novel Clade 4’ (Tectofilosida). We untangle this polyphyly by establishing Fisculla gen. nov. and the Fiscullidae fam. nov. for the former of these two clades. ]]>
