Polycystidea

Usage notes

• Taxonomic revisions and the adoption of standardized suffixes for naming biological entities appear to have rendered the name of this "division" obsolete. The intended organism appears to be a parasitic amoeba-like protozoan in the subclass Telosporea rather than the flatworm family Polycystidae.
