Taxonomy

Citation: Pseudotextularia Rzehak 1891
Rank: Genus
Basionym: Cuneolina elegans
Type species: Cuneolina elegans Rzehak, 1891
Taxonomic discussion: A neotype (Natural History Museum, Vienna, Geol.-Palaeont. Coln. MI-465) was designated (S. Nash, 1981, *2231, p. 74) for Pseudotextularia elegans (Rzehak) from the type locality.

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.
