Telonema is a genus of single-celled organisms.

Some sources group Telonema within the cryptomonads-haptophytes assemblage. [1] It is sometimes assigned to a unique phylum, Telonemia. [2] Although Telonema is within the Eukaryota Domain, it does not have any close relations to other organisms within that domain. [3] 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. [4] After a study of 127 genes across 72 species, they found that Telonema subtile could be related to Alveolata and Rhizaria. [4]

Species

Two species are recognized by AlgaeBase as of 2013, Telonema subtile and T. antarcticum . [5] The latter was described in 2005. [6]

Other sources call the former Telonema subtilis. [6] [7]
