Taxonomy

The order Archigregarinorida was redefined by Levine in 1971.Levine N D (1971) Taxonomy of the Archigregarinorida and Selenidiidae (Protozoa, Apicomplexa) J Euk Micro 18 (4) 704-717 DOI: 10.1111/j.1550-7408.1971.tb03401.x This reorganisation lead to the creation of two new families ( Exoschizonidae and Selenidioididae) and several genera including ''Selenidioides''. There are 11 species in this genus.

Life cycle

The parasites in the genus infect the gastrointestinal tract and are presumably transmitted by the orofaecal route but the details of this mechanism are presently unknown.
