Original Description

The smooth- to rough-walled, calcareous hyaline test is trochospirally coiled. Its small early chambers are globular, inflated, and globigerine-like. The last few chambers are elongated and extend into a relatively small umbilicus. The aperture is rounded interiomarginal, and opens into the umbilicus. Short apertural flaps extend into the umbilicus but do not form an umbilical cover-plate. Family Globotruncanidae.

Extra details from original publication
Remarks. - The most characteristic feature of Hedbergella, new name, is the extension of the last few chambers into the umbilicus. This represents a stage in the phylogeny from a Globigerina-like form to Ticinella Reichel, with a large umbilicus and umbilical cover-plate. In this lineage the enlarging umbilicus was at first minimized by extension of the last few chambers as a whole into it as represented by Hedbergella. Later in the lineage the umbilicus became too large to be filled in by the chambers themselves. However, by extending only the apertural flaps, and not the chambers as a whole, the large umbilicus was covered by an umbilical cover-plate composed of extended apertural flaps as represented by Ticinella.

Editors' Notes
This genus was originally described as Hedbergina, by Brönnimann & Brown 1956, with the type species Globigerina seminolensis Harlton. However, G. seminolensis proved on further research to be a problematic species and not a member of the group, so Bronnimann & Brown 1958 redescribed the genus with a new name and a different type species.
