Short diagnosis: monospecific

NB The short diagnoses are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They have initially been copied from the diagnostic characters/distinguishing features sections of the Eocene and Paleocene Atlases, they will be edited as the site is developed.

Description


Test morphology: Test medium, relatively high trochospiral, chambers globular to hemispherical, increasing regularly in size. The final whorl consists of three chambers, sutures radial to curved, depressed; surface smooth, microperforate with extremely fine perforations distributed irregularly (PI. 57, Fig. 8). Primary aperture not visible in the adult; numerous small, rounded secondary apertures, bordered by a rim, almost completely surround the later chambers. [Kennett & Srinivasan 1983]

Size: >250µm

Biogeography and Palaeobiology


Geographic distribution: Tropical to subtropical [Kennett & Srinivasan 1983]

Phylogenetic relations: Molecular genotypes recognised (data from PFR2 database, June 2017), one genotype only from 18 sequences. References: Ujiié & Lipps 2009.

Similar species: C. nitida is easily distinguished by its microperforate, trochoid test with sutural supplementary apertures completely surrounding the later chambers. [Kennett & Srinivasan 1983]
