Parvilucifera infectans
Diagnosis
Diagnosis_species: Alveolate endoparasite in dinoflagellates. Motile cells with two unequal flagella arising from the anterior part of the cell. The two flagella orthogonal, arising close together. Cells with few-membered conoid. Sporangium formed inside the host and covered by small spicules (processess). Each sporangium produces numerous swarmers.
zoospore has open conoid, rhoptry, and microneme-like structures root.
Body_spores_length: 4 µm
Body_spores_width: 1-1.5 µm
Etymology
parvus (Latin), small lucidus (Latin) shining, referring to the small refractile zooids; infectans (Latin), that infects.
Type species
This is the type species (holotype) of the genus Parvilucifera
