Species Paragloborotalia pseudokugleri Blow 1969


Discussion / Comments:
Spezzaferri & Silva (1990):
Rare specimens displaying transitional characters to P. kugleri occur at the top of the sequence. Recent investigations by Spezzaferri (in press) suggest that on the basis of the wall structure (cancellate with spines) the former "Globorotalia" kugleri group should be attributed to the genus Paragloborotalia.
Chaisson & Leckie (1993):
Remarks: Leckie et al. (this volume) present numerous illustrations of Paragloborotalia pseudokugleri with emphasis on its distinction from P. kugleri. Similar species: Paragloborotalia pseudokugleri is distinquished from P. kugleri by its rounded peripheral margin, radial dorsal sutures, and tendency to be more circular in equatorial outline.
