History

[edit]

Exoschizonidae was described by Levine in 1971.[1]

Taxonomy

[edit]

Exoschizon is the only genus currently recognised in the family Exoschizonidae. The genus has only one species - Exoschizon siphonosomae - which was described by Hukui in 1939.[2]

Description

[edit]

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.
