( Fig. 6S )

Material examined. MFM 145619 and 41 other referred specimens.

Remarks. The specimens are represented only by fragment of the cheliped fixed fingers. They cannot be identified to specific level. The present genus is one of the common genera within the decapod fauna of the Pleistocene of Japan (e.g., Kato & Karasawa 1998; Karasawa et al. 2014).
