Candidate division

A candidate division, candidate phylum or candidate division-level is a lineage of prokaryotic organisms for which until recently no cultured representatives have been found, but evidence of the existence of the clade has been obtained by 16S rRNA metagenomic analysis of environmental samples.[1] The term candidatus in fact means a species which there is insufficient information to call it a new species according to the International Code of Nomenclature of Bacteria[2]
