Telonema is a genus of single-celled organisms.
Some sources group Telonema within the cryptomonads-haptophytes assemblage. It is sometimes assigned to a unique phylum, Telonemia. Although Telonema is within the Eukaryota Domain, it does not have any close relations to other organisms within that domain. However, it was once thought Telonema was closely related to photosynthetic cryptomonads, or stramenopiles and centrohelids, but there was not enough data to prove this. After a study of 127 genes across 72 species, they found that Telonema subtile could be related to Alveolata and Rhizaria.
