Original Description
Test small (greater diameter up to 0.28 mm.), with a low spire, left- or right-coiling. Spiral side of the test flat or slightly concave, umbilical side always concave. Test outline from rounded to oval, lobate. Peripheral margin broadly rounded. In mature forms two whorls are observed, in the first of which there are 5-5.5 chambers, and in the second 5.5-7. The proloculus and the chambers in the first whorl are spherical. Later chambers are oval in outline on the spiral side. Chambers uniformly increase in size. Septal sutures straight, depressed. Umbilicus broad and deep. Aperture bordered by a short lip. Spatulate lips are incompletely covered over when a new chamber is added, their ends can be seen between the last two or three chambers. Wall thin, finely perforate, possibly primarily unilamellar. Test surface smooth. Microspheric and megalospheric forms are observed.

Etymology: Название вида от globus лат.—шар и feiio лат.—носить.
