Peridiniales
Family: 
Podolampidae
Genus: 
Podolampas

bipes var reticulata

P. bipes reticulata Kofoid 1907

Diagnosis

P. bipes and P. bipes var reticulata always contained autofluorescent endocytobionts, which were interpreted as dinoflagellate chloroplasts by former investigations based on light microscopy. Ultrastructural details of the endocytobionts show that they belong to the class Dictyochophyceae (Heterokontophyta), most probably to the order Pedinellales.

Body_dorsoventral: 43-56 µm
Body_length_appendage: 26-31 µm
Toxicity: No

Etymology

Kofoid (1907) distinguished reticulata from bipes mainly by its "very large and broadly rounded" antapical fins and its reticulated thecal surface. The present author found from Shimoda Bay some intermediate forms in addition to the two typical ones. In respect to the surface reticulation, all of the bove-mentioned forms cannot be distinguished from one another.

Type species

The type species (holotype) of the genus Podolampas is Podolampas bipes Stein.
