Range — Japan, lower or middle Pliocene of Tonohama.
Remarks — The author of this species considered its generic position doubtful but referred it provisionally to Turricula, and remarked that "it somewhat resembles T. sobrina (Yokoyama) and T. kamakurana (Pilsbry) from Japan. However the present species differs from the two above mentioned forms, not only in its outline but also in sculpture".
Although the apical whorls are missing, the general facies, the style of sculpture in particular, suggests Comitas as the most likely genus. From sobrina, this species is distinguished by its more broadly fusiform shape and more numerous axial folds.
