Diagnosis.

Bebryce with rosettes with warty, rounded, or bristle-like projections. Those of calycular margin asymmetrically developed, with strong projecting blade. Coenenchymal sclerites are thick, warty disks.

Remarks.

Apparently this is the most common Bebryce species in sub-tropical to temperate Japanese waters, in a depth range of 97-213 m.
