Original Description
Test free, trochospiral in first whorl, planispiral in later stages. Chambers spherical in juvenile stage, later chambers radially elongate. Wall calcareous, smooth, finely perforate, of radially crystalline structure, septa bilamellid. Aperture basal, a low equatorial arch.

Etymology: The generic name is from the Latin protensus, protentus meaning "stretched out," in reference to the typically elongate chambers of this genus +ella, diminutive. Gender: feminine.

Extra details from original publication
Remarks: Protentella may be differentiated from other hastigerinids and globigerinids by its planispiral test with radially elongate chambers in the later stages, and by the smooth wall texture. A few specimens have slight knobs on the chambers which may represent the bases of large spines, although because of their rare occurrence their significance could not be determined.
