Material examined. MFM 145618 and one other referred specimen.

Remarks. The present specimens lack the rostrum, but features of the carapace match with those of Podocatactes hamifer Ortmann, 1893 . Fossil specimens are known from the Lower Pleistocene Soga and Hijikata formations of Kakegawa Group (Karasawa 1993, 1997; Kitamura & Shiba 2008). Extant specimens are known from the lower sublittoral zone to bathyal zone around Japanese coasts (e.g., Takeda 2001).
