Original Description
The most primitive representatives of this genus are allocated to the subgenus Aragonella, typified by Hantkenina aragonensis Nuttall, 1930. The species placed in this subgenus have 5-6 bilaterally compressed, distinctly separated and stellate arranged chambers; each chamber is elongated distally and terminates in a spine. The chambers are longer than broad; the spines are situated in the prolongation of the chamber-axis; the sutures are straight or only slightly curved. The size of the specimens of this subgenus varies between 0.45 and 1.00 mm. Unbroken spines measure about one-half the length of the chambers. The aperture is not visible, usua1Iy filled and indistinct.
