Dentalina Risso, 1826

Guðmundsson, Guðmundur, Cedhagen, Tomas & Andersen, Tom, 2022, Taxonomy and distribution of recent species of the subfamily Nodosariinae (Foraminifera) in Icelandic waters, European Journal of Taxonomy 824 (1), pp. 1-74 : 5

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.
