Diagnosis

Diagnosis_species: Endoparasitoid infecting the cytoplasm of a wide range of dinoflagellates. The trophocyte develops inside the host. The sporangium is released into water. Sporangium wall covered by numerous processes 0.4-0.45 µm in length. Zoospores (6 µm in length, 1.8 µm in width) with two unequal flagella, anterior rostrum, are released from sporangium via opercules. Zoospore has open conoid, rhoptry, microneme-like structures root and large vacuole with electron translucent contents.

Etymology

rostrata referring to the rostrum of zoospores.

Type species

The type species (holotype) of the genus Parvilucifera is P. infectans.
