The approximatus-group of Cryptocephalus in Japan is reviewed. As the result the group is shown comprising 4 closely allied species, approximatus BALY, fortunatus BALY, nitidulus FABRICIUS and one new species, aeneoblitus, instead of 1 to 3 species as hitherto treated by authors. Morphological characters and biological or distributional data of these species are presented.
