Original Description

Test wall thin, microperforate, wall pores evenly distributed and variably spaced in adult chambers, surface smooth or with scattered and weakly developed pustules. Test small to moderate in size, coiled in a very low to low trochospire, spiral side evolute, umbilical side mostly involute; chambers globular, never elongated radially, increasing rapidly to moderately in size, with 3–6 in the final whorl; aperture a low interiomarginal, umbilical-extraumbilical arch bordered by a thin lip or flap that may extend partly into umbilical region.

Editors' Notes
Microhedbergella differs from Hedbergella primarily by its generally smaller size, particularly in the early species, by having a thinner shell wall (~2-3 µm; Fig. 9b) that is microperforate with a smooth surface, and by always having an apertural lip or flap. Microhedbergella resembles Praehedbergella because of its small test size, relatively thin wall and smooth wall texture, but these genera are considered as distantly related homeomorphic lineages because of the stratigraphic gap that separates species included within each of the genera.
