Current identification/main database link: Praegublerina acuta (De Klasz, 1953)
Description : The test consists of two divergent rows of more or less globular chambers connected with each other by a calcareous lamella. The latter also contains a varying number of irregularly dispersed, often partly reniform, chambers filling almost the whole space between the two lateral rows of chambers of some of the specimens. The chambers of the lateral divergent rows are separated from each other by depressed sutures. Their size is generally increasing from the first to the last, although this increase in size is not always regular. The size of the initial chambers is increasing more slowly than of these ones of G. cuvillieri. The last chambers are often elongating a little towards the centre of the test. The whole test is sometimes compressed in the vertical direction towards the symmetric plane of both divergent rows of chambers. The calcareous lamella, filling the space between these rows, occasionally encloses the upper end of the test and part of its flanks.
The aperture of the specimens found up to now could not be seen; it can be assumed however that it is at the inner basis of the last chamher like G. cuvillieri Kikoine.
