Description. Test very small for the genus, approximately 0.12—0.15 mm in diameter; trochospiral, biconvex but umbilical side more convex; periphery rounded; seven to eight chambers in the last whorl; sutures on dorsal side strongly curving backwards, umbilical side radiate; aperture interiomarginal extending to edge of periphery of last chamber; test thin and finely perforate.
Remarks. We could not find any taxon to assign this specimen to. This form might be a juvenile of any species of Cibicidoides , although all our specimens show the similar small test size and we regard them as adult.
Occurrence. Thirty-nine specimens from only a single sample of the Yonahama Formation.
