Anisonemidae is a small family of euglenid algae, with two accepted genera. It is the only family in the order Anisonemida.[1]
Description
[edit]The family consists of single-celled organisms with a larger posterior flagellum by means of which they are able to glide. They are phagotrophic, meaning that they feed by engulfing particles of food, and are non-photosynthetic.[1]
Taxonomy
[edit]The family was established by William Saville-Kent in a work published in 1880–1881.[2][3] Saville-Kent used a much wider circumscription than more recent sources.[3] Historically, phagotrophic euglenids have been treated as animals, and named under the International Code of Zoological Nomenclature,[1] hence the family name ending "-idae".
Genera
[edit]As of May 2023[update], two genera are accepted:[1]
A third genus, Heteronema Dujardin, 1841, is listed by some sources.[2] The status of the genus is unclear; it appears to be polyphyletic, with some species falling into the order Peranemida and others in Anisonemida. Many of its species have been transferred into Teloprocta, which is placed in Peranemida.[1]
