Subfamily Nodosariinae Ehrenberg, 1838

Diagnosis

The diagnostic characters of the family Nodosariinae are a uniserial chamber arrangement and a rectilinear to slightly arcuate test in the megalospheric generation, with a terminal aperture made of radiate slits or grooves around the margin ( Hayward et al. 2012). The few and rarely encountered specimens of the microspheric generation of Dentalina antarctica Parr, 1950 , Dentalina elegans d’Orbigny, 1846 , Dentalina obliqua ( Linnaeus,1758) , and Nodosaria incerta Neugeboren, 1856 have rudiments of a planispiral arrangement of the very first initial chambers.
