Compared with:

1954 Saracenaria akitaensis Iwasa and Kikuchi , p. 191, text-fig. 3.

Diagnosis. Species with rounded triangular shape in cross section and smooth surface without depressed sutures and inflation of chambers.

Remarks. In general shape, this form closely resembles S. akitaensis originally described from the middle Miocene of northern Japan. Specimens from Miyakojima, however, have a smaller test size (about 0.6 mm in diameter) than S. akitaensis (1.5 mm in the original description).

Occurrence. Rare in the Yonahama and Minebari formations.
