Anaerocyclidiidae fam. nov. (Oligohymenophorea, Scuticociliatia): A newly recognized major lineage of anaerobic ciliates hosting prokaryotic symbionts
Original language description
The research on anaerobic ciliates, to date, has mainly been focused on representatives of obligately anaerobic classes such as Armophorea or Plagiopylea. In this study, we focus on the anaerobic representatives of the subclass Scuticociliatia, members of the class Oligohymenophorea, which is mainly composed of aerobic ciliates. Until now, only a single anaerobic species, Cyclidium porcatum (here transferred to the genus Anaerocyclidium gen. nov.), has been described both molecularly and morphologically. Our broad sampling of anoxic sediments together with cultivation and single cell sequencing approaches have shown that scuticociliates are common and diversified in anoxic environments. Our results show that anaerobic scuticociliates represent a distinctive evolutionary lineage not closely related to the family Cyclidiidae (order Pleuronematida), as previously suggested. However, the phylogenetic position of the newly recognized lineage within the subclass Scuticociliatia remains unresolved. Based on molecular and morphological data, we establish the family Anaerocyclidiidae fam. nov. to accommodate members of this clade. We further provide detailed morphological descriptions and 18S rRNA gene sequences for six new Anaerocyclidium species and significantly broaden the described diversity of anaerobic scuticociliates.
