The type genus is Monocystis.

History

This subfamily was created by Bütschli in 1882[1] and modified by Bhatia in 1930.[2]

Description

The species in this subfamily are cylindroid in shape with a mucron at the anterior end.

The trophozoites are solitary.

Syzygy occurs late in the life cycle.

They parasitise the coelom of earthworms and are spread by the orofaecal route.
