Résumé
Thecofilosea is a class in Cercozoa (Rhizaria) comprising mainly freshwater-inhabiting algivores. Recently, numerous isolates of thecofilosean amoebae have been cultured and were characterized by an integrated morphological and molecular approach. The captivating spine-bearing taxa in Thecofilosea were not yet molecularly characterized due to being very rare. There are only two known spine-bearing species, Pamphagus armatus and Lecythium spinosum, which were synonymized by Penard in 1902. Due to a morphological difference of those taxa, we discuss here that we disagree with this taxonomical act. We further isolated single cells of Pamphagus armatus directly from their habitat and successfully sequenced their SSU rDNA, which we subjected to phylogenetic analyses. We show that Pamphagus armatus branches within the Rhizaspididae (Tectofilosida, Thecofilosea). Accordingly, we transfer Pamphagus armatus and the assumingly closely related species Lecythium spinosum to Rhizaspis.
