Favositid tabulate corals described by Kamei (1955) from the Early Devonian Fukuji Formation, Gifu Prefecture are reexamined. The assignments of the available specimens in the Kamei's original material using up to date taxonomic knowledge are as follows: Favosites ichinotanensis Kamei, 1955, Mesofavosites igoi (Kamei, 1955), Sapporipora kamitakaraensis Tsukada, 2005, Plicatomurus flexuosus (Kamei, 1955), Squameopora hidensis (Kamei, 1955), Squameopora takarensis (Kamei, 1955), Squameofavosites fukujensis (Kamei, 1955), Squameofavosites sugiyamai (Kamei, 1955), and Squameofavosites sp. indet. Plicatomurus was not previously known in Japan. On the basis of the emended generic diagnosis of Squameopora, its systematic position is transferred from the subfamily Favositinae to Pachyfavositinae.
