Taxonomy
Original description: Mit der Gattung Cuneolina, wie sie ursprünglich von d'Orbigny aufgestellt wurde, lässt sich unsere Form ohne Zwang nicht vereinigen. Sie weicht aber auch von den typischen Textularien so weit ab, dass die Aufstellung einer neuen Gattung — Pseudotextularia — gerechtfertigt sein dürfte. Es ist nicht unmöglich, dass die von verschiedenen Autoren beschriebenen tri- und multiserialen Textularien ebenfalls hieher gehören.
Entries in the Catalog of original descriptions: Pseudotextularia
Distinguishing features: Adult biserial chambers expanded such that test breadth is greater than width in side view.
Morphology: Test subtriangular in outline, with biserially arranged, inflated chambers compressed parallel to the line of junction between the two series of chambers so that the test appears broader in apertural or edge view than from the sides with the zigzag suture between chambers, sutures depressed; wall calcareous, finely perforate, surface with longitudinal, slightly irregular to discontinuous fine to medium coarse costae; aperture a broad low to medium arched basal opening bordered by a narrow lip.
