Original Description

Test flat dorsally and considerably inflated ventrally, six-seven chambers in the last volution, one finely beaded keel. The chambers increase more rapidly in size as in Glt. gansseri gansseri and are more inflated even dorsally; the test is rougher. The inner volutions are not visible because of the fairly developed rugosity.

Dimensions of holotype: Width 0.58 x 0.54 mm.; thickness, 0.38 mm.

Extra details from original publication
Remarks.— It differs from the Glt. gansseri gansseri because of the greater number of chambers in the last whorl, the smaller size, the less evident keel, the more inflated chambers.
