Original Description
Species placed in the subgenus Hantkenina, typified by Hantkenina alabamensis Cushman, 1924, are characterized by having chambers which increase rapidly in size, are generally broader than long, inflated, definite in outline, and clearly separated. The test is closely coiled, although in some species one notes a tendency towards slight uncoiling in the lastformed whorl. The spines are of variable length; they are situated near or at the end of the suture; usually the spines are radially oriented but sometimes they may be inclined backwards or forwards, tangentially to the contour of the test. The sutures are radiate, generally straight, and deeply furrowed. Aperture slitlike, arched, or tripartite (clover-like). Specimens of this subgenus attain a size varying between 0.4 and 0.8 mm. [Thalmann 1942]
