Sister taxa: P. dimorphosus, P. tenuiculus, P. martinii, P. bisulcus, P. sp.

Taxonomy:

Citation: Prinsius martinii (Perch-Nielsen, 1969) Haq, 1971
Rank: Species
Basionym: Ericsonia martinii Perch-Nielsen, 1969
Taxonomic discussion: Similar to Prinsius bisulcus but smaller (Wei & Liu, 1992).

Distinguishing features: Small (<5.5µm), elliptical placoliths with conspicuous tube cycle and closed centre.

Farinacci & Howe catalog pages: E. martinii + *


Morphology:

Slightly larger then P. dimorphosus. Similar to Prinsius bisulcus but smaller.


Size: <=5.5 µm. NB <5µm according to Wei & Liu, 1992 but shifted to 5.5µm by Bown (2016), in order to include the Prinsius martinii holotype)

Most likely ancestor: Prinsius dimorphosus - at confidence level 3 (out of 5). Data source: Romein 1979 p72-3.
Likely descendants: Prinsius bisulcus;
