Entosiphon is a genus of euglenids. It was described by Friedrich Stein in 1878.
==Description== Entosiphon is a genus of phagotrophic euglenids, single-celled flagellates with two flagella characterized by a protein pellicle present beneath the cell membrane. In particular, Entosiphon cells are distinguished by a protrusible ingestion apparatus. Their pellicle is composed of twelve protein strips. ==Classification== The genus Entosiphon was described by Friedrich Stein in 1878. It was established to transfer a species of Anisonema, A. sulcata, to a separate genus, which changed the original spelling of this species to E. sulcatum. A second species, E. oblongum, was described in 2016. The genus was placed in a separate family Entosiphonidae the same year.
