Polycystidea

New Latin, see poly-, and Cystidea.

Polycystidea

1. (obsolete, zoology) A division of Gregarinia including those that have two or more internal divisions of the body.
2. (obsolete, zoology) A species of large brown algae, Cystophora polycystidea found in Spencer Gulf, South Australia.

• 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.
