Species

Tetradesmus is a genus of green algae in the family Scenedesmaceae.[1] Species of Tetradesmus are found in a variety of habitats, including fresh water and biological soil crusts in deserts.[2]

Taxonomy

The genus Tetradesmus was described by Gilbert Morgan Smith, containing the single species Tetradesmus wisconsinensis. It was not universally accepted; Robert Hippolyte Chodat synonymized the genus into Scenedesmus, while George Stephen West accepted the genus as separate from Scenedesmus.[3]

In the 2000s, molecular data revealed found that Scenedesmus was polyphyletic. Scenedesmus was subsequently split up into several genera, corresponding to the former subgenera Scenedesmus, Desmodesmus, and Acutodesmus.[3] As Tetradesmus species are phylogenetically closely related to species once placed in Scenedesmus subgenus Acutodesmus, the genus Acutodesmus was raised to genus rank and Tetradesmus was placed as a synonym of Acutodesmus.[4] However, since the name Tetradesmus was published before the genus combination Acutodesmus was made, this meant that the name Tetradesmus had priority Therefore, species in Acutodesmus were renamed to Tetradesmus.[5]
