The Exoschizonidae are a family in the phylum Apicomplexa.
This family was created by Levine in 1971.
There is one genus currently recognised in this family - Exoschizon. This genus has only one species - Exoschizon siphonosomae - which was described by Hukui in 1939.
This species was found in the intestine of a sipunculid worm (Siphonosoma cumanense) in Japan.
The meronts measure 90 µm × 15 µm. There are ~13 longitudinal striations per side.
The meronts and gamonts are similarly shaped.
Transmission is presumably by the orofaecal route.
