 The Monocystinae are a subfamily of parasitic alveolates in the phylum Apicomplexa. 
  Taxonomy
 There are seven genera in this subfamily. 
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.
