Comparison. - This species was erroneously referred to (Shutskaya, 1953. loc. cit. ) as Globigerina praebulloides. with which it has no features in common except for the rotaloid arrangement of the chambers in the initial part of the test. In the Globigerina varianta group it is closest to G. moskvini Shutskaya, from which it differs (Shutskaya, 1970, op. cit., table 1) by the low-trochospiral rather than flattened-trochospiral coiling or the whorls in the initial part of the test, the smaller number of chambers, their gradual enlargement and spherical shape, thin deep sutures, and umbilical aperture. The distinctive features of the species make it possible to identify it in the literature (see synonymy) also, demonstrating its broad geographic distribution.
