Species Globigerinella pseudobesa Salvatorini 1966 |
|
|
Diagnosis / Definition: |
Kennett & Srinivasan (1983):
Test low trochospiral, equatorial periphery strongly lobulate, axial periphery broadly rounded; chambers spherical to subspherical; four rapidly enlarging cham-
bers in the final whorl; spiral sutures radial, depressed; umbilical sutures slightly curved to nearly radial; surface densely perforated with circular to subcircular pores and elevated circular spine bases. Umbilicus wide and deep; aperture interiomarginal, umbilical-extraumbilical, a rather medium-wide arch extending to the spiral side of the test, without a lip or rim. |
Discussion / Comments: |
Kennett & Srinivasan (1983):
Ge. pseudobesa shows a wide range of variation in apertural position from extraumbilical to nearly umbilical as in Glo-
bigerina. The aperture commonly extends onto the spiral side of the test. Ge. pseudobesa closely resembles Ge. obesa but differs in the highly variable apertural position. |
