Classification: ntax_mesozoic -> Podorhabdales -> Axopodorhabdaceae -> Perissocyclus -> Perissocyclus noeliae
Sister taxa: P. fenestratus, P. liesbergensis, P. noeliae, P. plethotretus, P. tayloriae, P. sp.

Taxonomy:

Citation: Perissocyclus noeliae Black, 1971
Rank: Species
Variants:

Farinacci & Howe catalog pages: P. noelae + * , P. fletcheri *

Distinguishing features: Small to medium Perissocyclus (5-7 µm) with 9-18 perforations in the outer ring.


Morphology: Wind & Cepek (1979) give a long description and discission. We follow their concept of a rather variable species here.
