Description
Genus Dentalina Risso, 1826
Diagnosis
Elongate, arcuate, uniserial tests; chambers cylindrical to ovate, sutures oblique; wall calcareous, hyaline radial in structure; aperture terminal and radiate. The generic distinction (Loeblich & Tappan 1986) between species with a smooth surface of Laevidentalina and a costate exterior of Dentalina is not used here, following Hayward et al. (2012: 109, 236). Dentalina differs from Nodosaria in having more oblique than horizontal sutures, and test shape is more arcuate than straight, and more cylindrical than nodular.
