The Platyproteum are a genus of parasitic alveolates in the phylum Apicomplexa.
Species in this genus infect marine invertebrates.
This genus was described in 2009 by Sonja Reuckert and Brian Leander.
This species was moved from the genus Selenidium.
The parasite infects the gastrointestinal tract and is presumably transmitted by the orofaecal route but the details of this mechanism are presently unknown.
