Entries in the Catalog of original descriptions: Gublerina
Parent taxon (Heterohelicidae): Aperture symmetrical, ranging from a low slit to a high arch at the base of the final chamber, becoming terminal in uniserial taxa.
This taxon: Test flabelliform, the 2 rows of chambers diverge leaving nonseptate central space that later is partially occupied by chamber proliferation.
Morphology: Test compressed, flabelliform, early stage planispiral, later biserial and increasing rapidly in breadth, the two series of chambers diverging to leave a broad nonseptate central area that later is partially occupied by chamber proliferation, sutures depressed; wall calcareous, finely perforate, ornamented with longitudinal costae and nodes, most prominently in the early stage; aperture an arch at the base of the final chamber.
