Remarks. Hansenisca soldanii (d’Orbigny) of Loeblich and Tappan (1987, 1994) does not appear to be conspecific with Gyroidina soldanii of Papp and Schmid (1985), who restudied the type specimens of d’Orbigny. Hansenisca soldanii of Loeblich and Tappan (1987, 1994) shows a broadly opened umbilicus and slit-like opening along the dorsal side of the ultimate whorl.

Occurrence. Common in the Onogoshi, Yonahama, and Minebari formations.
