A new species of Ceratocephale is described from Wakasa Bay, Sea of Japan. Among 10 Ceratocephale species ever described world-wide the present species is closest to C. pacifica (Hartman, 1960) or C. pacifica (sensu Hutchings and Reid, 1990) in lacking mid-dorsal papillae in median body region and any falcigers and having double neuropodial cirri from setiger 1 and sesquigomph spinigers. But the present species differs from the latter two in having two pairs of distinct eyespots on the prostomium. While the present species is from the continental shelf area, the latter two are abyssal dwellers. This is the first record of this genus from Northwest Pacific region.
