Paracercomonas is a genus of wild flagellates . It wasseparatedfrom the genus Cercomonas in 2006. They occur in soil and water.

features

The protozoa are sliding flagellates with a very flexible body. At every point in the cell they form pseudopodia of different shapes , including branched filopodia . During the movement, the cells touch the ground. The front flagellum performs slow, rowing movements, the rear flagella is dragged more passively.

Some species have a complex life cycle that includes multinucleated plasmodia and cysts . The mitochondria have cristae in the form of rounded tubules.

They differ from the closely related genera Cercomonas and Eocercomonas by the presence of cartwheels on both centrioles as well as by molecular genetic features.

Systematics

The genus Paracercomonas was separated from the genus Cercomonas in 2006 . It is the sister group of the pair Cercomonas and Eocercomonas along with some undescribed species :
