Genus KUGLERINA

KUGLERINA Brönnimann and Brown. 1956
 
 
Type species: Rugoglobigerina rugosa subsp. rotundata Brönnimann,1952 (*373), p. 34; OD.
Kuglerina Brönnimann and Brown. 1956 (*394), p. 557. Helvetiella Longoria and Gamper. 1984 (*1935), p. 174;
type species: Helvetiella helvetia Longoria and Gamper.1984; OD.
Test relatively large, up to 0.5 mm in diameter, with moderately high trochospiral coil, chambers globular to somewhat elongate as seen in edge view, enlarging gradually, four to six in the final whorl, sutures radial, depressed, umbilicus about one-fourth the test diameter, periphery rounded, noncarinate, peripheral outline lobulate: wall calcareous, perforate, surface with prominent pustules and rugosities but without regularly aligned costellae; primary aperture umbilical, provided with tegilla and with both proximal and distal accessory apertures. U. Cretaceous (M. to U. Maastrichtian); Trinidad; Tunisia.
 
Remarks: 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.
