Two Early Devonian species of coenitid tabulate corals, Coenites fukujiensis sp. nov. and Planocoenites ozakii sp. nov., are described from the D4 Member (Emsian?) or the float blocks probably derived from this member of the Fukuji Formation in the Fukuji area, Gifu Prefecture. Coenites fukujiensis is diagnosed by its strong sinuations in the intercorallite walls, whose morphology separates it from all other species of the genus. The most similar species with Planocoenites ozakii is Placocoenites [sic] hinganensis Tchi, 1980 that known from Heilongjiang, Northeast China. But, the Chinese species has the much thicker coralla and the attenuated intercorallite walls. Comparable form with Planocoenites ozakii is also reported from the Hitoegane Formation, Gifu Prefecture.
