Original Description: "The small and lentricular test is composed of four to five closely coiled chambers which increase gradually in size. The general outline is subcircular to subelliptical. The sutures are rather indistinct, straight to very slightly curved. The umbilicus is indistinct and small. "The glassy and usually pointed spines are very thick and short for the genus. They are situated in the prolongation of the sutures, except the early ones which lie below the anterior sutures as in H. (Applinella) longispira (Cushman). "The surface is granulate and appears rough. The aperture is not visible but probably is the elongate tripartite slit of Hantkenina s.s. "Maximum diameter without spines: 0.3-0.4 mm. Length of spines: 0.1-0.2 mm.
