Citation: Kuglerina Brönnimann and Brown 1956
Rank: Genus
Basionym: Rugoglobigerina rngosa subsp. rotundata
Type species: Rugoglobigerina rngosa subsp. rotundata Brönnimann, 1952
Taxonomic discussion: Helvetiella was described as differing from Rugoglobigerina in lacking a meridional alignment of rugosities and from Archaeoglobigerina in lacking an imperforate carinal band (although none is present in the type species of either) and in the heavily ornamented surface. However, it appears very similar to Kuglerina and is here regarded as synonymous.

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous
