Subfamily Dagmaritinae Bozorgnia, 1973 View in CoL
Genera included: Dagmarita Reitlinger, 1965 ; Louisettita Altıner and Brönnimann, 1980 ; Danielita Altıner and Özkan-Altıner, 2010 .
Description.—Test free, elongated in shape, evolute, rounded peripheral outline, biserial, uncoiled. Subspheric chambers, semi-circular to semi-ellipsoidal in axial section. Presence of outer thornlike projections of the test wall. Endoskeletal septal partitions (peripheral chamberlets) are present in Louisettita . Test wall plurilayered composed of dark microgranular and white median or outer hyaline layer. The microgranular layer described with perforations (in Danielita ). Aperture interiomarginal depressed and protected by a valvular projection.
Stratigraphic and geographic range.—Roadian (Zheng 1986) (Guadalupian, Permian) to late Changhsingian (Lopingian, Permian) of the Palaeotethys, the Neotethys, and the Panthalassa ( Japan and North America).
The first appearance datum (FAD) of the Dagmaritinae is based on the FAD of the genus Dagmarita . Zheng (1986) recorded the first appearance of this taxon in the sample D40 of the Chihsia (= Qixia) Formation (South China), which has been referred to the Verbeekina grabaui Zone. This biozone corresponds to the Roadian Neoschwagerina simplex Zone ( Nestell and Nestell 2006; Angiolini et al. 2015).
